Jerry Lake
For example -
$NewString = ereg_replace("([[:alpha:]]+) ", "\\1".chr(9), $String);
This will convert a sequence of one or more alphabetic characters followed
by one space to the same set of characters followed by a tab (that's the
chr(9) part).
If you want to match only a specific set of text characters - say, a, e, i,
o and u - then you can use
$NewString = eregi_replace("([aeiou]+) ", "\\1".chr(9), $String);
Notice i used eregi_replace() instead of ereg_replace(); the 'i' means case
INsensitive.
Of course, there are other ways of doing this with preg_replace and
str_replace, both of which are faster than ereg_replace (str_replace is the
fastest); I happen to use ereg becaouse I'm most familiar with it, since it
came along before the preg_ functions. As always, you can check out the docs:
http://www.php.net/ereg_replace
http://www.php.net/eregi_replace

I tried doubleval() without success and I can't use intval() because it

kind regards,

If you really need to make this a float variable, then you can add

Subject: [PHP] Form data is not "remembered"
Hi,
I have a page with a couple of form fields that are being POSTed to a
processing PHP script. The page that contains these form fields is itself
a
PHP page that uses sessions and so on.
I have to make "server-side data validation" on the fields because of
their
complexity. When the user hits submit and comes to the result page, if
there
was any error I ask the user to go back to the form and correct the
mistakes, using either his browser BACK button or by clicking on a link
that
does a javascript:history.back().
The problem is, when the user gets back to the form page, all of the
values
he had typed in are gone, and he has to start all over again. Does anyone
have an idea why this is so, and how to circumvent it without saving the
user data into a session variable and then setting it back again once the
user hits the form page again ? I have seen many pages where your previous
data would stay in the form after you make a "Back" operation, but here,
it
disappears.
Some browsers will save the entered info when you hit the BACK
button, some won't; it also depends on your HTTP header settings
(no-cache, must-revalidate, etc.). Probably bad idea to rely on that.
In a nutshell, if your validation fails, don't tell the user to hit
the back button. Instead, redisplay the form with the data fields
already filled in.
I usually write my form display process programs something like
this (assuming $Submit is the name attribute of the submit button):
...
if ($Submit = 'Enter your data') {
$ErrorList = validate_form_data();
if (is_array($ErrorList)) {
show_form($ErrorList);
} else {
process_data();
}
} else {
show_form();
}
...
Where:
validate_form_data is a function that returns an array of
error messages like $ErrorList[form field name] = error message,
or FALSE if all tests passed. If there are errors, I redisplay the
form with entered data (from $HTTP_POST_VARS or wherever), and error
messages displayed alongside the appropriate form fields.
show_form displays the entry form, with any existing data
(from HTTP_POST_VARS, etc.) filled in and error messages, if any,
displayed. Basically, the FORM tag action attribute refers to the
same program as displayed the form - that is, $PHP_SELF.
Hope this is clear...I getting tired, and I don't even think an
intravenous drip of concentrated Mountain Dew syrup will help.

"A return statement will terminate the evaluation of the string

So, if you're using PHP4, just ensure that there is a return

Of course, you would want to do your own processing in place of the echo.
If you want to use POSTed or cookie variables, replace the _GET_ in
the above snippet with _POST_ or _COOKIE_, respectively.
The reset(), by the way, resets the array pointer to the beginning of
the array. It's not always needed, but I tend to do it anyway. It IS
necessary, however, ig you use the above snippet within an enclosing
loop.

Take a look under date/time functions:
http://www.php.net/manual/en/ref.datetime.php
You want to convert your stored time into a Unix timestamp (that is,
seconds since midnight 1 jan 1970), subtract the unix timestamp of
the current time, and then display the result in your desired format:
$Deadline = ' 27:01:2001:08:13';
$Bits = explode(':', $Deadline);
$TimeDiff =
mktime($Bits[3],$Bits[4],$Bits[5],$Bits[1],$Bits[0],$Bits[2])
- time();
# $TimeDiff is now the time difference, expressed in seconds.
# Now, use modulo operator repeatedly to get day, hour minute values.
# BTW, there are 86400 seconds/day, 3600 seconds/hour.
$NDays = $TimeDiff % 86400;
$R = $TimeDiff - ($NDays * 86400);
$NHours = $R % 3600;
$R = $R - ($NHours * 3600);
$NMinutes = round($R/60);
echo "You have $NDays days, $NHours hours and $NMinutes left!";
If you're feeling obfuscatory, you could compact the calculations
into (I think):
$NHours = ($R = $TimeDiff - (($NDays = $TimeDiff % 86400) *
86400)) % 3600;
$NMinutes = round(($R - ($NHours * 3600))/60);
Why you would _want_ to do this, I don't know. I suppose if you're an
ex-FORTRAN programmer frustrated by the lack of assigned and computed
GOTOs and want to take it out on others, maybe. OK, now I'm rambling.
And showing my age...

Hi!
When I use the echo to see what is inside the list(). Instead I got the
message on screen saying "ArrayArray".
The array are being assigned first then then list come second. ie.
$test = array();
$test1 = array()
list($test,$test1);
---
When I do "echo list($test,$test1);", it doesn't work.
What are the better way to see the data in the array?
Are these actual program snippets? If they are then
(1) '$test1 = array()' line is missing a trailing ';'
(2) The statement 'list($test,$test1);', to the best of my knowledge,
does nothing in this context.
(3) From your echo statement, you should see the output
'list(Array,Array)' - functions and language constructs aren't
evaluated in double-quoted strings; only variables.
It would make more sense to me to have something like
$test = array('bean', 'noodle', 'wednesday');
$test1 = array('a'='apple', 'b'='banana', 'c'='carrot');
$foo = array($test, $test1);
Then you could display these values like so:
If you have PHP4, use print_r() or var_dump():
echo print_r($foo);
See
http://www.php.net/manual/en/function.print-r.php
http://www.php.net/manual/en/function.var-dump.php
I haven't used either of these functions, so I don't know exactly
what the output looks like. It says var_dump() was available in PHP 3
after 3.0.5, but I'm not entirely sure that's true. If it is, it must
have been undocumented for a while.
An alternative display method would be something like (a little more
cumbersome, but works in PHP3 4):
for ($i=0; $icount($foo); $i++)
{
while(list($Key,$Val) = each($foo[$i]))
{
echo "foo[$i][$Key] = $Valbr\n";
}
}
Also, instead of the
$test = array('bean', 'noodle', 'wednesday');
$test1 = array('a'='apple', 'b'='banana', 'c'='carrot');
$foo = array($test, $test1);
way of declaring the $foo array, you could also say
$foo = array(
array('bean', 'noodle', 'wednesday'),
array('a'='apple', 'b'='banana', 'c'='carrot')
)
or
$foo[0] = array('bean', 'noodle', 'wednesday');
$foo[1] = array('a'='apple', 'b'='banana', 'c'='carrot');
See
http://www.php.net/manual/en/language.types.array.php

The var is part of the syntax of a class definition; it isn't used anywhere else. I don't know the actual deep reason for having it, as far as the parser is concerned, but it does make it clear - at least to me - what the class variables are. class definitions are the fundamental building blocks of object orientated programming. They define an object type which your object is an example of. The defined variables should be regarded as properties of the class rather than variables in the usual sense. If you're going to be strict about it you should not even refer to them directly outside the class definition but use methods to access and change them.

You can also initialize the variable here, too: var $a = 5; not any more you can't ... use the constructor According to the docs, you can still use a _constant_ initializer in PHP4 (I use them in 4.0.4), just not a variable one. From http://www.php.net/manual/en/language.oop.php: Note: In PHP 4, only constant initializers for var variables are allowed. Use constructors for non-constant initializers.

You don't need the $hash in that function call unless you need to use
it later on in your main program, so you can just say:
foo (array('var1'='value', 'var2'='value'));
which is basically the same as the Perl or Ruby (??? never heard of
that...) call above, with the addition of array(...). I use the
function(array('param1'='value', ...))
syntax a lot instead of individual parameters in function calls. I
don't have to remember function argument order that way.

Now, I don't undestand why exactly do you need references. By default
everything is passed in a referenced manner, if I undestood correct the
explanation Zeev wrote right after 4.0 was out, or so.
Don't take references like something that will boost your skript speed
to 200%.
Use them only when you need them, and to find out when you actually need
them
check out an article on references at zend.com.
Now, let me tell you that somehow I agreed with you :) cause I love
Python way
of dealing with arrays, but we are in PHP, so we have to figure PHP way,
not
your-fav-lang way.

Well, in this case, you'd have to use regular expressions. One way to do it
would be:
$SanitizedString =
ereg_replace('[[:space:]]*([[:alnum:]]+)[^]*', "\\1", $String);
this _should_ work (haven't tested it). If you wanted to remove some tags
entirely, and then remove the attributes of the remaining tags, you could
(1) use strip_tags() with a list of allowable tags, then (2) run the regexp
above. Incidentally, the above regexp also removes leading spaces from the
tag. Eg,font style="unreadable" becomes font. If you don't want,
that user the regexp
'([[:space:]]*[[:alnum:]]+)[^]*'
instead.

alternatively, you could do

Re: [PHP] string to array??
Actually, you can treat a string as an array without any further processing:
$Globbot = 'dribcot';
echo $Globbot[0]; # echoes 'd'
echo $Globbot[6]; # echoes 't'
Check out 'String access by character' about halfway down the page at
http://www.php.net/manual/en/language.types.string.php
(or, in Portuguese,
http://www.php.net/manual/pt_BR/language.types.string.php

Actually, using the [] syntax is deprecated - using {} is the new way
- but I'm a creature of habit...

Re: [PHP] string to array??
Sorry if I was less than totally clear; I was referring to this part
of the page:
Characters within strings may be accessed by specifying the
zero-based offset of the desired character after the string in curly
braces.
Note: For backwards compatibility, you can still use the
array-braces. However, this syntax is deprecated as of PHP 4.
Example 6-3. Some string examples
SNIP
/* Get the first character of a string */
$str = 'This is a test.'
$first = $str{0};
...and that was the first I'd noticed that myself; I assume that the
{} syntax is only being used to refer to arrays as strings, to avoid
confusion with an array of strings -
$str = array('string 1', 'thing 2');
echo $str[0]; # produces 'string 1'
- and a scalar string variable being treated as an array of
characters. So I'm guessing (too lazy to test right at the moment)
that you would get
$str = array(array('bork','fubar'), 'snafu');
echo $str[0][1]; # produces 'fubar'
echo $str[1][1]; # produces null
echo $str[1]{1}; # produces 'n'
Again, that's just what I'm assuming from the docs. A quick test
would clear it up, but it doesn't affect me right now, and I'm
feeling lazy ;)
Hope that clears up my statement...

I call this from a PHP page with the following code:
begin code--
$myCourses = getCourses($session[id]);
foreach ($myCourses as $value)
{
print br$value;
}
end code---
Now, when I test the SQL from my function directly on the database, it
returns just want I want it to return but it isn't working that way on my
PHP page. For results where there is a single entry, I am getting the same
entry TWICE and for records with more than a single entry I am getting ONLY
the FIRST entry TWICE.
Now I know my SQL code is correct (I am testing it against a MySQL database
using MySQL-Front) so I suspect I'm doing something stupid in my foreach
loop.
I think your problem lies in a misunderstanding of the
mysql_fetch_array() function. It doesn't return the entire result set
in an array - just one record at a time. You can fix this in one of
two ways:
(1) Loop though the entire result set in your function:
function getCourses($UID)
{
global $link;
$ResultSet = array();
$result = mysql_query( SELECT C.CourseName FROM tblcourses C, tblusers U,
tblEnrollment E WHERE C.ID = E.CourseID AND E.UserID = U.ID AND U.ID =
$UID, $link );
if ( ! $result )
die ( getRow fatal error: .mysql_error() );
while ($Row = mysql_fetch_array( $result ))
{
$ResultSet[] = $Row['C.CourseName'];
}
return $ResultSet;
}
...
$myCourses = getCourses($session[id]);
foreach ($myCourses as $value)
{
print br$value;
}
or (2) set a flag in getCourses() so that the query is only executed
once, otherwise returning a result line - something like:
function getCourses($UID)
global $link;
static $result = false;
if (!$result)
{
$result = mysql_query( SELECT C.CourseName FROM tblcourses C,
tblusers U,
tblEnrollment E WHERE C.ID = E.CourseID AND E.UserID = U.ID AND U.ID =
$UID, $link );
if ( ! $result )
die ( getRow fatal error: .mysql_error() );
}
{
return mysql_fetch_array( $result );
}
...
while ($Row = getCourses($session[id]) as $value)
{
print br, $Row['C.CourseName'];
}
(standard caveats about off-top-of-head, untested code apply)
The reason you are getting the first record TWICE is becaouse of the
default behaviour of the mysql_fetch_array() function. It returns
both an associative array - ie, elements of the form field-name =
value - and a numerically indexed array (0, 1, 2, etc.). You can
alter this behaviour by the second parameter of the function: see
http://www.php.net/manual/en/function.mysql-fetch-array.php

I'm hoping someone will spot my dumb mistake. Thanks very much for any help

This make total sense to me. Now, I was pretty sure that
I was getting an array back from mysql_fetch_array because when I do a
'print $myCourses' without specifying any value, I just get 'array' which I
believe I am supposed to, IF it is truly an array. Anyway, I'm going to
revisit the mysql_fetch_array function right now. Thanks for your help, it
is greatly appreciated.
...Brad
Just to clarify a bit - mysql_fetch_array() DOES return an array -
thus the name - but it is an array containing one record from the
result set. For instance, if the result of the statement
SELECT C.CourseName
FROM tblcourses C, tblusers U, tblEnrollment E
WHERE C.ID = E.CourseID AND E.UserID = U.ID AND U.ID = 1
through the MySQL commandline was
+-+
| C.CourseName|
+-+
| Basketweaving |
| Noodle twirling |
| Poodle furling |
| Puddle curling |
+-+
then the first use of mysql_fetch_array($result) through PHP would
retrieve the array
'C.CourseName' = 'Basketweaving',
0 = 'Basketweaving'
the second call would retrieve
'C.CourseName' = ' Noodle twirling',
0 = ' Noodle twirling'
and so on. If you had two columns in the result set:
+-++
| C.CourseName| C.CourseNo |
+-++
| Basketweaving | 12 |
| Noodle twirling | 23 |
| Poodle furling | 24 |
| Puddle curling | 25 |
+-++
you would get results like
'C.CourseName' = 'Basketweaving',
0 = 'Basketweaving',
'C.CourseNo' = 12,
1 = 12
and so on. The reason you get the doubled keys (associative
numeric) is for historical compatibility; to turn off the feature,
and retrieve only the associated indexes (the behavior you normally
want), you can use
mysql_fetch_array($result, MYSQL_ASSOC);
Incidentally, I just learned something here myself; there's a
relatively new (= version 4.0.3) function mysql_fetch_assoc() which
does what you want...return ONLY the associated indexes. See:
http://www.php.net/manual/en/function.mysql-fetch-assoc.php

No, but you can do it this way:
switch ($foo) {
case 1:

do_something();
break;
case 2:

break;
case 3:

Re: [PHP] Check for Associative Array

What's the best way to check for an Associative Array? There is no
is_assoc() or similiar function listed in the manual (I don't think anyway).
No, because AFAIK all PHP arrays are associative; there is no
distinction between arrays hashes as in Perl.
I'm using mysql_fetch_array() and I want to foreach only the assoc. part of
the array without using mysql_fetch_assoc():
foreach ($arr as $key=$value) {
echo $key:$value;
}
If you really don't want to use mysql_fetch_assoc(), you can use the
second parameter of mysql_fetch_array():
$arr = mysql_fetch_array($ResultHandle, MYSQL_FETCH_ASSOC);
This functions exactly like mysql_fetch_assoc(), and is available in
PHP = 3.0.7.
See
http://www.php.net/manual/en/function.mysql-fetch-array.php
for more info.
But of course it show both the indexed array and the assoc array contents.
Is there an existing function to check this, or should I do one of these
things inside the foreach loop:
A) set $last=value and just check if $value = $lastval
B) check if the $key is just a number or just a string
C) $key += 1
Lastly, you _could_ just step through the array using each() in a
loop, and use only every OTHER array entry...but this is really funky
and you shouldn't do it this way anymore.

Re: [PHP] viewing get/post variables
You might be thinking of the register_globals parameter here, instead of safe_mode: http://php.he.net/manual/en/configuration.php#ini.register-globals It is, in general best to keep this off so that you can explicitly validate user input. If you trust the POST or GET data, though, you can turn register_globals ON or use the extract() function - http://php.he.net/manual/en/function.extract.php - for example: extract($HTTP_GET_VARS); echo $var1; or in a function, extract($GLOBALS['HTTP_GET_VARS']); echo $var1; I don't think the safe_mode setting affects this, but I'm not sure. Some of the default settings may have changed between 4.0.6 4.2; that might explain why behavior changed after upgrading. -steve At 10:43 AM -0300 4/16/02, Martín Marqués wrote: On Mar 16 Abr 2002 10:35, Christoph Starkmann [EMAIL PROTECTED] wrote: Hi Martín!

http://php.he.net/manual/en/control-structures.alternative-syntax.php

If you are using the alternative syntax, I recall several messages

all one style or the other.
Lastly, quadruple check that you haven't accidentally quoted or
double-quoted a { or ( or something that you THOUGHT was part of PHP

Re: [PHP] whitespace...

How do I remove the whitespace from a document? I consulted the manual and
it said to use the trim function. But in a large PHP document, with lots
of fuctions etc in PHP... is there a simple way to compress the whitespace
of the entire document? Rather than going through each var and using the
trim? Like add a header at the top: ?PHP compresswhitespace() ?
If you have a 300k php document, won't the source code reveal (after the
browser displays the page) a bunch of whitespace. Doesn't this add to dl
time and if so, how do I get rid of it.
Not 100% sure if I understand the drift of your question, but here's a few
possibilities.
(1) Are you concerned about whitespace you put in a PHP program to enhance
readability slowing down page loads?
Any whitespace WITHIN PHP tags does not get sent to the browser at all. So
you don't need to worry about it.
(2) Are you concerned that the OUTPUT of your PHP program and/or HTML
embedded therein might have excessive whitespace? If so, you could create
an output handler that cleans up the output before sending, I think; see
http://www.php.net/manual/en/ref.outcontrol.php
Or, use compression. See:
http://www.php.net/manual/en/function.ob-gzhandler.php
(3) If you simply wanted to clean up excessive whitespace in a file, you
could use a snippet like:
...read file into $file variable
# Replace multiple spaces/tabs with a space
$file = preg_replace('/[ \t]{2,}/','/ /', $file);
# Replace multiple lines with single line
$file = preg_replace('/(\n|\r|\r\n){2,}/', '\r', $file);
...write $file back out
That last line for replacing multiple blank lines is probably wrong; at the
very least you'd have to do some platform checking (Win vs. Mac vs. Unix)
to get the proper line ending. You might also be able to use the pattern
'/(^$){2,}/m'
In PHP4 I think you can use arrays:
...read in
$file = preg_replace(
array('/[ \t]{2,}/', '/(\n|\r|\r\n){2,}/'),
array('/ /', '\r'),
$file
);
...write out
See
http://www.php.net/manual/en/function.preg-replace.php

Re: [PHP] PHP and Apache
It's certainly _possible_ -
Your httpd.conf (I'm assuming you use Apache, of course) file is just
a text file that can be read/written like anything else. Then you
could do a
system('/path/to/apache/bin/apachectl restart');
to activate. Doing it this simply, thoughm means that your
webserver's user (usually nobody) would have write access to the conf
file and execute perms to apachectl, which could open up some
bulldozer-security holes. At the very least, you want to access
things through SSL.
But you might want to try Webmin:
http://www.webmin.com/
Looks very comprehensive, and I've seem a number of good
recommendations for it. I've been planning on doing a little testing
of it on my test server, but haven't had the time.

Re: [PHP] Need more memory... possible to set?
Several ways:
(1) PHP still reads a php.ini file, so you could set it there; try a
php -i | grep php.ini
to find out where the commandline php thinks it is (and/or do
php -i | grep memory_limit
to find the default memory limit setting.
(2) You can set it at execution time via the -d command option:
php -d memory_limit=20M -f yourprogram.php
(3) Set it in your program with the ini_set() command:

If you want a case insensitive match, use eregi(...) instead. The
above regexp allows passwords as short as 2 characters. If you want
to, for example, enforce a password length of 4 to 8 characters, you
can do:
ereg('^[a-z][-a-z0-9\._]{2,6}[a-z]$', $TestPwd)

Is it just me or is there anyone else that thinks PHP suffers from not being modular. Let me explain myself. If you write a module for a lot of procedural languages it sits on the filling system and is called up when it is needed , loaded into memory and executed. There maybe some cashing which happens but this is basically how it works. PHP on the other hand seems to load in ALL the code that MAY be run. i.e. an include brings things in which are inside an if, even if the if equates to false. Not true; require() has this behavior, but include() does not. See http://php.he.net/manual/en/function.require.php and http://php.he.net/manual/en/function.include.php -steve This means that the language is not extendible in the way others are. If you do write a function you wish to include in 'only the pages you wish to use' you have to first include it, then call it. This has also meant that things like spell checking functions are built into the core module rather than called in as or when they are needed. Then there is the way database connectivity is handled. There are a load of functions (again in the core language) with there NAMES containing the name of the database you are connecting to. For example all MySQL functions are mysql_something and I guess all oracle ones are oracle_something. This would only be a minor inconvenience because wrapper functions can be written but from what I can gather different databases have different functionality available. I know this is partly because different databases have different functionality. what I would expect to see is a load of generic function which attempt to provide same functionality where it is available or implement some of the functionality themselves. Obviously for some of the less sophisticated databases these functions would have to do more work and maybe some functionality wouldn't be available in certain databases (but only the things like stored procedures). If you can deal with the 'lowest common denominator' approach, use ODBC. Or, as you mentioned, use one of the db wrapper classes available in PHPLIB, PEAR or Metabase. -steve -- + Open source questions? + | Steve Edberg University of California, Davis | | [EMAIL PROTECTED] Computer Consultant | | http://aesric.ucdavis.edu/ http://pgfsun.ucdavis.edu/ | +--- http://pgfsun.ucdavis.edu/open-source-tools.html ---+ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Syntax here is wrong; you don't need to declare function arguments
using var; only class variables need that. I'm uncertain what will
happen if you do this. I would expect that - if PHP's error reporting

So do either:
(1) Drop the 'var $HTTP_POST_VARS line;
OR do
(2)
clas Member{
var $HTTP_POST_VARS;
function vallidateForm (){
echo $this-HTTP_POST_VARS['frmUsername'];

Although option (2) would require rewriting the code below.
Also I assume that the 'clas Member{' line is just a typo, and your
actual code says 'class Member{'...
$user = new Member;
if($action==register){
global $HTTP_POST_VARS;
$user-vallidateForm($HTTP_POST_VARS);
}else{
$user-displayForm();
}
?
But i can't acces $HTTP_POST_VARS['frmUsername'] within the function
If you are using an old (any PHP3.x, and I think some early betas of
PHP4) version of PHP, you need to turn 'track_vars' on to enable
$HTTP_POST_VARS and other $HTTP_xxx_VARS arrays. If that's the case -
and you can't upgrade immediately - you need to turn track_vars on in
httpd.conf, php.ini, or .htaccess (whatever's appropriate in your
setup).
Hope that helps -

RE: [PHP] ucwords Except 'The' 'And' etc?
Something like this, perhaps (untested):
function smart_ucwords($String)
{
$ExceptionList = array('the', 'an', 'a'); # should all be in lowercase
$String = ucwords(strtolower(ltrim($String))); # LINE A
foreach ($ExceptionList as $Word)
{
$String = eregi_replace([[:space:]]+$Word[[:space:]]+,
$Word, $String);
}
return $String; # LINE B
}
This will leave the exception word capitalized if it is the first
word in the $String (as it should be), or if it is the last work in
the $String (unlikely). If you want to handle cases where the
exception word comes at the end of the string, just replace LINE A
above with
$String = ucwords(strtolower($String)).' ';
and LINE B with
return rtrim($String);
Of course, there will be exceptions that are near-impossible to
programmatically determine, eg;
'Dr. Martin van Hooten Hears a Who'
in this case, van should be lower case, since it isn't referring to a
medium-capacity box-like automobile, tennis shoe brand, or naval
vanguard.

I know, I know, I have a lot of work to do...I shouldn't be doing
this. I did get to play with PCRE regexps here, though...lotsa cool
features over eregs!. Anyway, here's a *** NEW!!! IMPROVED!!! ***
version of smart_ucwords(), that's probably way too much overkill. I
did some quick tests, seems to work. Beware of email-induced
line-wrapping, particularly in the comment black quoted strings:
?php
function smart_ucwords($String, $ForceCase=1, $CapitalizeTrailing=1) {
#
# A more sophisticated approach to title-casing.
#
## PARAMETERS
##
#
# $String string Input string.
# $ForceCase 0|1 If true, will force title case (only
first letter
#capitalized, no matter what case the
string is in.
# $CaptializeTrailing 0|1 If true, will capitalize a normally-excepted
#word if it is the last word in the
string. So, a
#string like 'Shot In the Dark, A'
works properly.
#
## USAGE NOTES
#
#
# The Exception List words should be in the case you desire;
normally this will
# be lowercase.
#
# The Invariant List contains words and titles (eg; NASA, MySQL, PostGreSQL,
# eBusiness) whose capitalization should be fixed, no matter what.
#
# If one of these arrays is not to be used, simply set it to array().

$INVARIANT_LIST = array(

);
# First, strip save leading trailing whitespace
preg_match(

Re: [PHP] Errors
Well, since you're getting a PHP error, PHP is obviously parsing the
page. My guess is that your error reporting (in php.ini, httpd.conf
or .htaccess) is set very high, so that uninitialized variables
generate a warning. You could either (1) initialize $page at the top
of your program:
$page = false;
or (2) lower the warning level:

If $page is coming from somewhere else (eg; GET/POST parameters) then
you can test for its existence like so:
if (!isset($page)) { $page = false; }
or $page = 0...whatever's appropriate.

Hi
I'm getting strange errors if I add
LoadModule php4_module ../php/sapi/php4apache.dll to http.conf
If I don't load it everything is working with php.exe without any

load it as a modul I get for example -
Warning: Undefined variable: page in d:\abria

here is the page.inc file:
?php
if (!$page):
$page = 1;

$limit = ($page * 10) - 10;

What is wrong? I need php as a modul but what do I do
wrong, I did everything according to install.txt in php

Re: [PHP] Sorting IP Address Data (oops!)
And if the numbers are from different subnets, you could sort like so
(assuming addresses are in a 1-dimensional array, here called
$IpAddresses):
function sort_address($IpAddresses) {
$List = array();
foreach ($IpAddresses as $A) {
list($x,$y,$z,$t) = explode('.', $A);
$List[($x*16777216) + ($y*6553616) + ($z*256) + $t] = $A;
}
ksort($List, SORT_NUMERIC);
return array_values($List);
}
My first thought was to use the line
$List[($x24) + ($y16) + ($z8) + $t] = $A;
instead, and gain a little speed advantage by bitshifting instead of
multiplying, but then you'd need to force $x, $y, $z and $t to
integers first. You might be able to do
$List[(((int)$x)24) + (((int)$y)16) + (((int)$z)8) + $t] = $A;
or
$List[(($x+0)24) + (($y+0)16) + (($z+0)8) + $t] = $A;
I MADE A BIT OF A CUT'N'PASTE ERROR IN THE LINE ABOVE IN MY PREVIOUS EMAIL!
instead, though. If you wanted 'em in REVERSE order, use krsort()
instead of ksort().
Usual 'untested code' warnings apply.

$num=123 is an integer *and* numeric value.
$num='123' might not be an integer, but it is

now the problem of how to devise a proper test for

That's because $fp is a file POINTER, not the actual contents of the
file. You might have been thinking of the file() function, which
sucks the entire contents of the file into an array...very wasteful,
if all you need are the first few lines. What you want here is:
$fp = fopen(meh.txt,r);
for($i=0;$i2;$i++)
{
print fread($fp, 4096);
}
or
unset($FileArray);
$fp = fopen(meh.txt,r);
for($i=0;$i2;$i++)
{
$FileArray[] = fread($fp, 4096);
}
foreach($FileArray as $line)
{
print $line;
}
The second parameter in the fread function is the maximum line
length; normally, that would be set to ma number larger than the
maximum line length you're likely to encounter (unless you have long
lines, and only need the first few characters of that line). See:
http://www.php.net/manual/en/function.fopen.php
and
http://www.php.net/manual/en/function.fread.php
Also, the line
print $fp[$i];
isn't likely to work the way you expect; if $fp was an array, you'd
get something like
Array[0]
Array[1]
Array[2]
as the printout, since the $i, in quotes, wouldn't be interpreted as
an array index. Use something like
print $fp[$i];
or
print Some text here .$fp[$i]. more text here;
instead.

Re: [PHP] PHP Redirect in the middle of code?
Right off the top of my head, you have three options that I can see: (1) Rewrite the code to avoid any output before the redirect. (2) Use output buffering (available only in PHP4). I haven't used this, but check out http://www.php.net/manual/en/ref.outcontrol.php (3) Use a META REFRESH tag. For example: META HTTP-EQUIV=refresh CONTENT=1;page.php where 1 is the time (in seconds) before you want the redirect, and 'page.php' is where you want the redirect to. Of course, this tag needs to be in the HEAD section, so it might not help you much. As far as I know, though, cold fusion's cflocation tag only works because CF does output buffering implicitly. So, I'd guess you need to do option (2). -steve At 10:37 AM -0400 9/10/01, Andrew Penniman wrote: I am trying to figure out how to use PHP to redirect the user to a new location *after* processing and most likely outputting a bunch of code.

Re: [PHP] header redirection
It's my understanding that PHP's normal behavior IS to send the header when it is encountered in your program, and then continue running the program (unless you have an exit statement after the header). Perhaps you have output buffering turned on? If that's not the case, please most more info, and perhaps the relevant parts of the script if possible. By the way, I'm pretty sure you don't need those trailing newlines (\n\n) there; PHP takes care of that for you.

[PHP] Re: excuting several sql statements in one time
This is more of a MySQL question, but:
Actually, as of MySQL version 3.22.5, INSERT statements can have
multiple value lists. In your case, this would be
$query =
INSERT INTO com VALUES .
('pentium'), ('amd');
mysql_query($query, $dbconnect) or die(mysql_error());
Also, you don't need a trailing ';' on the SQL query statement (you
DO need it, of course, at the end of the PHP statement).
See
http://www.mysql.com/doc/I/N/INSERT.html
for more information.

delete this line, and you'll be happy.
while($query_data = mysql_fetch_array($result)) {
$firstname = $query_data[firstname];
$email = $query_data[email];
$optin = $query_data[optin];
echo BR\n;
echo $firstname;$email;$optin\n;

[PHP] Re: string formatting help
In the original message below, did you mean that you're actually
SEEING the br tags in the output? If so, there may be a conversion
with htmlentities() going on somewhere that converts the br tags to
lt;brgt; (so they are displayed instead of being interpreted).
If you replaced the br's with spaces or newlines, the output
_should_ all be on one line, since HTML considers ALL strings of
whitespace (tabs, newlines, returns, spaces) to be a single space. If
you replaced br's with newlines and you are getting the line breaks
still, your output may be in a pre.../pre block.

$variables = array($author_firstname, $author_lastname, $author_dob,
$author_dod, $author_bio);
foreach($variables as $value) {
$value = strip_tags($value);
$value = AddSlashes($value);
}
will the values be changed outside of the loop?
No, because $value is a copy the current array element, not simply a
pointer to it. Furthermore, if I understand the documentation (see
below) correctly, this construct (using the $variables array from
above) -
$i = 0;
foreach ($variables as $value)
{
$variables[$i] =AddSlashes( strip_tags($value));
$i++;
}
- will not work either, since foreach() operates a COPY of the array.
From the docs at
http://www.php.net/manual/en/control-structures.foreach.php :
Note: When foreach first starts executing, the internal array pointer
is automatically reset to the first element of the array. This means
that you do not need to call reset() before a foreach loop.
Note: Also note that foreach operates on a copy of the specified
array, not the array itself, therefore the array pointer is not
modified as with the each() construct and changes to the array
element returned are not reflected in the original array.

Re: [PHP] Name of an array???
Not quite sure what you're getting at here. As you discovered, if you have
$Thing = array(5,6,7,8);
and you 'echo $Thing;' you get 'Array.' However, in this case, you
know the variable name already - $Thing!
Are you thinking more along these lines:
$ArrayName = 'Thing';
$$ArrayName = array(5,6,7,8);
now,
echo $ArrayName;== Thing
echo $$ArrayName; == Array
echo ${$ArrayName}[0]; == 5
See
http://www.php.net/manual/en/language.variables.variable.php
for more info.

Re: [PHP] sorting results of opendir()
Here's one way:
$dir = opendir('.');
unset($FileList);
while ($file=readdir($dir)) {
if($file!= '.' $file != '..')
{
$FileList[] = $file;
}
}
sort $FileList;
reset($FileList);
while(list(, $F) = each($FileList)) {
echo $Fbr\n;
}
If you're using PHP4, you can replace everything after the
sort($FileList) with the more compact:
foreach($FileList as $F) { echo $Fbr\n; }
See
http://www.php.net/manual/en/function.sort.php

Re: [PHP] Help..Parse error
My guess is that you have the short_open_tags option on in your PHP3 config, but off in your PHP4 config. If it's off, PHP will only recognize the ?php...? tags, not ?...?. PHP config params can be set in php.ini, .htaccess, and/or Apache httpd.conf files. Scroll down to short_open_tag in http://www.php.net/manual/en/configuration.php#configuration.file for more info.

Re: [PHP] Using $$ to access a variable
I'm not sure that your construct will work; however, you could always do
echo $HTTP_POST_VARS[$table_array[$iCnt][0]];
in place of 'echo $$var' or
$var = 'HTTP_POST_VARS';
echo ${$var}[$table_array[$iCnt][0]];
When using variable variables, the array index - here, 'ld_val' might
not be interpreted correctly; I'm guessing that PHP is looking for a
variable named 'HTTP_POST_VARS[ld_val]', not an element of the
HTTP_POST_VARS array. More info is at
http://www.php.net/manual/en/language.variables.variable.php
On the other hand, are you absolutely sure that something (other than
whitespace) is actually IN $HTTP_POST_VARS['ld_val'] ??

Cold Fusion has a wonderful function called CreateODBCDate(), which

Does PHP have a similar function? I've looked for one but can't
seem to find it anywhere.
From
http://www.php.net/manual/en/function.strtotime.php
-
"strtotime - Parse about any english textual datetime
description into a UNIX timestamp"
If the ODBC timestamp looks like
-mm-dd hh:mm:ss
then you could do:
$Date = '1 jan 2001';
ODBCDate = date('Y-m-d H:i:s', strtotime($Date));
And if you really want, just define the function
function CreateODBCDate($DateString)
{
return date('Y-m-d H:i:s', strtotime($DateString));
}
and you can ease your CF-PHP transition :)
If you want to default to returning the current date:
function CreateODBCDate($DateString='')
{
return
(
$DateString ?
date('Y-m-d H:i:s', strtotime($DateString)) :
date('Y-m-d H:i:s')
);
}
Sorry about the weird indent style --- I was trying to avoid wordwrapping.
It doesn't specify in the docs, but I _assume_ strtotime() returns
false if it can't figure out what the date string is...you might want
to test that.

Two possibilities I can think of:
(1) Is your echo statement above within a function? If so, you have
to globalize it, or pass it as a function parameter:
function zaphod($beeblebrox)
{
return 'div align="center"'.
$beeblebrox.
'/div';
}
echo zaphod($contents);
or
function zaphod()
{
global $contents;
return 'div align="center"'.
$contents.
'/div';
}
echo zaphod();
See
http://www.php.net/manual/en/language.variables.scope.php
for more info.
(2) The register_globals parameter is not set. This must be on if you
want GET/POST/COOKIE etc. parameters to be automagically converted to
variables. This can be set in php.ini, .htaccess, or httpd.conf, and
can also be programmatically set and checked via ini_set() and
ini_get(), respectively. If this is NOT set, you'll have to refer to
your GET parameter as
$HTTP_GET_VARS['contents']

I think - if you're feeling obscure - that

while
(($count = 10) print 'Number is '.$count++." br\n")

will work too. As will - using alternate while syntax -
$count = 0;

In your HTMLTable() function, use

$this-attributes[] = array("cellpadding", "0");
otherwise, PHP thinks $attributes is a variable local to that

Hi all,

if ($value == 5)

The above doesn't seem to work. In one of my scenarios, when I encounter
and error in a foreach loop, I need the ability to rewind the array
pointer by one. How can I achieve this?
echo $numbers[$index-1] . PHP_EOL;
That will only give me the value of the previous index. What I want is to
rewind the array pointer and continue with the loop.
I would think that if you rewound the array pointer as above, you'd
simply end up in an infinite loop, as you'd keep hitting the
condition that triggered the rewind. So I'm assuming you have some
other test in there and this is just a stripped down example.
If you're using a one-dimensional array, as opposed to a
multidimensional and/or associative array, you can do (untested):
$Count = count($numbers);
for ($i=0; $i$Count; $i++) {
$value = $numbers[$i];
if ($value == 5 some_other_test()) {
$value = $numbers[--$i];
}
echo Value: $value . PHP_EOL;
}
Wouldn't be much more complex to extend to a multidimensional array
with an integer index. If you were using an associative array with a
string index, you'd probably have to do something like
$NotJustNumbers = array('a'='slurm', 'b'='fry', 'c'='leela');
$Keys = array_keys($NotJustNumbers);
$Count = count($Keys);
for ($i=0; $i$Count; $i++) {
$value = $NotJustNumbers[$Keys[$i]];
if ($value == 5 some_other_test()) {
$value = $NotJustNumbers[$Keys[--$i]];
}
echo Value: $value . PHP_EOL;

if ($_GET['foo'] == 'y')...
and
if ($_GET['foo'] == '1')...
or even
if ($_GET['foo'] == 'Oui')...
One should really not do be doing just
if ($_GET['foo'])
anyway. Checking that a specific value is passed, rather than just
some value that PHP evaluates to true or false, is one way to catch
possible form hacking. For general reference, there are a number of
php security howtos out there on how to sanitize user input, but I'll
leave finding them as an 'excercize for the reader' at the moment. I
suppose using 0/1 does have the advantage of 'doing the right thing'
if a if ($_GET['foo']) creeps into your code, though. As would
using 'Y'/''.
That being said, I've used 0/1 along with y/n in the past; it depends
on whether I'm thinking like a programmer or a human ;)

First of all, using y and n for boolean values (such as a checkbox) is
very sloppy. n is boolean True. A boolean value should evaluate correctly
in a boolean context. For that, you should use 1 and 0 for your values.
What I usually do is this:
input type=hidden name=foo value=0 /
input type=checkbox name=foo value=1 ?php echo $checked; ? /
Then when it gets submitted, foo will get the value of the form element that
was submitted last that has a value. That is, if the checkbox is checked
then foo will be 1, otherwise it will be 0. That gives you a nice, clean
boolean value you can rely on being present (mostly g).

I am checking if the allowed fields match the sent fields.
From the database I get the information if a checkbox is checked or not:
?php if($DB_a ==y) {
$checked=checked;
} else {
$checked=;
}
?
input type=checkbox name=R_a value=y ?php echo $checked ?
If the user takes out the checkmark the value will become and the
field will not submitted which results in a missing field.
$allowed = array();
$allowed[]='form';
$allowed[]='R_a';
$allowed[]='R_b';
$sent = $array_keys($_POST);
if($allowed == $sent) {
... do some checking ...
} else {
echo Expected input fields do not match!;
}
break;
How can I force a n for not checked in the input field? or how can I
solve that?

Re: [PHP] var_dump() results
At 12:32 PM -0500 1/13/08, Europus wrote:
It's pretty much the same. With var_dump(), values from the first row
of the table are iterated twice, the script is not looping through and
reporting all 2100 rows. Grossly similar behavior was observed with
print_r() and echo: while different data was reported by each, the
loop wouldn't loop. The first row was reported once (or twice) and
that was the end of that. I've tried foreach() also, same-same. It
doesn't loop, it just reports the first row.
Here's my code:
?php
//connect to db
$link = mysql_pconnect('$host', '$login', '$passwd');
if (!$link) {
die('Unable to connect : ' . mysql_error());
}
// make $table the current db
$db_selected = mysql_select_db('$table', $link);
if (!$db_selected) {
die ('Unable to select $table : ' . mysql_error());
}
//get column data
$sql= SELECT column2, column3 FROM $table;
$result = mysql_query($sql);
$row = mysql_fetch_row($result);
//loop through to display results
for($i=0; $i count($row); $i++){
var_dump($row);
echo br /br /;
?
Ulex
As far as displaying only the first row, that's because you're only
fetching the first row; count($row) in your for loop will always
evaluate to 0 (if there are no results) or 1. You need to move the
mysql_fetch_row() call into your loop; something like
$result = mysql_query($sql);
while ($row = mysql_fetch_row($result)) {
var_dump($row);
...
}
or you could do
$result = mysql_query($sql);
$count = mysql_num_rows($result);
for ($i=0; $i$count; $i++) {
var_dump($row);
...
}
As far as displaying the results twice, I'm not sure; that resembles
the behavior of mysql_fetch_array() -
http://us.php.net/manual/en/function.mysql-fetch-array.php
- where the default is to return data as both an associative and
numerically-indexed array. I'm guessing that the above code isn't an
exact cut-and-paste, as using single quotes (eg,
mysql_pconnect('$host', '$login', '$passwd') does not interpolate
variables, so that line will not work unless your username is
actually '$login', etc. Which it probably isn't. Are you sure the
real code isn't using mysql_fetch_array() instead of
mysql_fetch_row()?

What I would do is something like this (assuming your table has a column 'filename' in it): Create a cron job (on windows, I think the command is called 'at'?) that runs this query select filename from photo_table order by rand() limit 1 once per day, then copies that file to a predefined location (eg images/pic_of_the_day.jpg). Then, your web page simply refers to images/pic_of_the_day.jpg. The contents of pic_of_the_day.jpg change every time the cronjob runs (unless you randomly pick the same picture twice; not likely with 1000 rows, but you could include some sort of flag [eg; last used date] to avoid picking the same image twice, or to cycle through all images before reusing them). This requires one database hit per day, returning one row, so the load is next to nothing. The cronjob could be written in any language, but since this is a PHP list you'll have to promise to write it in PHP ;) steve -- +--- my people are the people of the dessert, ---+ | Steve Edberghttp://pgfsun.ucdavis.edu/ | | UC Davis Genome Center[EMAIL PROTECTED] | | Bioinformatics programming/database/sysadmin (530)754-9127 | + said t e lawrence, picking up his fork + -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Yeah, that's probably why most popular scripting languages support it.
In Ruby:
def foo
1, 2
end
a, b = foo
In Python:
def foo
return 1, 2
a, b = foo
In Perl:
sub foo
{
return (1, 2);
}
(my $a, my $b) = foo;
For completeness sake, this is pretty much the same in PHP:
function test() {
return array(1,2);
}
list($a,$b) = test();
works as above. Works fine with complex arrays as well:
function test() {
return array(1,array('a','b'));
}
list($a,$b) = test();

You might want to check the HTTP_REFERER value; test the program from
a browser and the swf, and see what happens. Alternatively you could
use a GET parameter like
http://example.com/yourscript.php?calledby=swf
Be aware that anything sent back from the client can be spoofed - and
HTTP_REFERER can be altered or disabled - so it probably wouldn't be
hard for someone to make it appear to your script that it is being
called by your SWF.
If you're really concerned about restricting the communication
between the Flash movie and your server, there might be some way to
build a challenge-response mechanism into the flash; I don't know
much about it.
If, on the other hand, you just don't want to confuse someone who
might accidentally run the XML-generating script from the browser,
checking a GET parameter as above is probably the safest. If it's not
set properly, redirect the user, eg:
if (!isset($_GET['calledby']) || $_GET['calledby'] != 'swf') {
header('Location: http://example.com/thecorrectpage.html');
exit();
}
...
