Re: [PHP] Re: My experience with the Forms Generation and Validation class
Guys! Here you both have a really good oportunity. You have contacted each other and say a lot, try to make something of this! Think on what you have done, design your idea, diagram a new set of classes, propose an implementation, work together and write the best form generation tool for all the community.

I had seen Manuel promoting his formsgeneration class on the mailing list and thought I'd look into it to help keep the project within the deadline. I read some positive reviews and comments, the demos looked promising, and the interface seemed good enough. Little did I know the headaches I was in for. I found the configuration structures and interface to be extremely cumbersome, not to mention terribly documented. The interface seems quite inefficient and in most cases its easier just to throw together a form and validation code by hand. Usage was often convoluted, and due to the poor documentation I spent half my effort trying to decipher the interface. And it was difficult to customize in several areas. While it can work well enough in several simple cases, in my opinion it is too cumbersome for any significant form processing project, especially in the business world. I ended up wasting a week of work using the formsgeneration class and had to redo the project making my own form utility code from scratch as I went (which took just as much time and actually worked as intended). Granted I did make the mistake of not giving myself enough evaluation time before the project. I just want caution others to carefully evaluate this code before deciding to use it in their projects, especially since Manuel seems so eager to promote his code (and his web site) whenever the opportunity arises. And in general, to be cautious and take your time when evaluating any 3rd party code for production use. There seems to be a misunderstanding. I am not eager to promote my code. I just look forward to have my classes tested by as many people as possible, so I get as many bug reports and feature improvements as possible. The fact is that I developed this and many other packages for my own purposes. Nowadays I could not live without them because they make me several orders of magnitude more productive than if I had to do it edit HTML code mannually as you said you did. Anyway, maybe this surprises you, but I like criticism. Especially constructive criticisms from people that are able to give specific examples of what they do not like, instead of making vague claims as you did. I like constructive criticism because it helps me making my code better, more useful to others and ultimately to myself. That is why I publish my work as Open Source. Unfortunately you did make any constructive criticism. There seems to be no way to improve my work because you were not specific to what exactly you find cumbersome, even less what you would different to make it less cumbersome. I never claimed it would be perfect for everybody. What is good and productive for some, maybe hard and difficult for others, especially if you try to learn all by yourself and never ask for help. The class has a support forum where you can ask questions and always get a response so you never get stuck. http://www.phpclasses.org/discuss/package/1/ Anyway, I don't know if you ever asked for help because you are using an anonymous identity here. Actually, I wonder why you bother to write a special message anonymously just campaign against the forms class. It makes me wonder if you have other reasons to do it that you may not be revealing unrelated with the class. Anyway, I am not upset. I am just sorry that you made many criticisms without giving real examples to demonstrate your points. That way it will not be helpful to anybody. -- Regards, Manuel Lemos Find and post PHP jobs http://www.phpclasses.org/jobs/ PHP Classes - Free ready to use OOP components written in PHP http://www.phpclasses.org/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- Martin Scotta

Lets say the HTML from that sends data to this script has 3 upload forms
that get send to $_FILES, would I access the data by modifying the following
line from the above example:
...
foreach($_FILES[' UPLOADIMAGE1 '] as $file_name = $file_array) {

...
foreach($_FILES[' UPLOADIMAGE2 '] as $file_name = $file_array) {

Your foreach does exactly what you are asking.
foreach($_FILES as $file_name = $file_array)
The keys in $_FILES are the input type=file / in your form.
If you have 3 files... then count( $_FILES ) should be 3

I believe that it determines if the return value of somefunc() is
non-false. It will have the added benefit then that you can use the
return value afterwards if it was, for example, not true, but a string
or something instead.
I do this all the time... an example is the following:
?php
if( ($user = get_current_user()) )
{
// Yay, we have a user... do something.
echo $user-name();
}
else
{
// Handle no current user.
echo 'Anonymous';

Hey everyone, I have an issue.
I need my (employee) users to be able to insert shows into the our MySQL
database and simultaneously upload an image file (and store the path in the

I have accomplished this with a product-based system (adding products and
uploading images of the product), and accomplished what I needed because
the
product name was unique; I used the following statements:
$prodName = $_POST['prodName'];
$prodDesc = $_POST['prodDesc'];
$prodPrice = $_POST['prodPrice'];
$query2 = INSERT INTO product (pID, pName) VALUES (NULL, '$prodName');;
$result2 = mysql_query($query2) or die(mysql_error());

$result = mysql_query($query) or die(mysql_error());
$row = mysql_fetch_array($result) or die (mysql_error());
$prodID = $row['pID'];
I had to select the new product to get the product id to use in the new
unique image name.
The problem I am facing now, is that with the shows that my users add will
have multitple show times; this means non-unique titles. In fact, the only
unique identifier is the show id. How can I insert something (leaving the
show_id field NULL so that it is auto-assigned the next ID number), and
then
immediately select it?
PHP doesn't seem to be able to immediately select something it has just
inserted, perhaps it needs time to process the database update.
Here is the code I have now (which does not work):
$query2 = INSERT INTO afy_show (show_id, show_title, show_day_w,
show_month, show_day_m, show_year, show_time, show_price, show_description,
show_comments_1, show_seats_reqd) VALUES (NULL, '{$show_title}',
'{$show_day_w}', '{$show_month}', '{$show_day_m}', '{$show_year}',
'{$show_time}', '{$show_price}', '{$show_description}',
'{$show_comments_1}', '{$show_seats_reqd}');;
$result2 = mysql_query($query2) or die(mysql_error());
$query3 = SELECT * FROM afy_show WHERE *show_id = '$id'*;;
$result3 = mysql_query($query3) or die('Record cannot be located!' .
mysql_error());
$row3 = mysql_fetch_array($result3);
$show_id = $row3['show_id'];
How do I select the item I just inserted to obtain the ID number??

Using the same type way as before in this thread.

No I don't think it is. It produces $test and if this is what you need

Did you mean the variable derived by $arr[3]?
echo This works: {$$arr[3]};
since curly brackets make the meaning of the expression explicit, it will
be 3 indeed.
What is the less ambiguous, readable, easy to maintain, way to obtain that
result?
echo This works: {${$arr[3]}};

But in php anything other than 0 translates to true, meaning a 1. What I
am trying to achieve is for a 1 to be a 1 and a true or false to be a true
and false respectively and I do not want to put quotes around the word
true/false either because then it is no longer a boolean but string.
Is it possible to overwrite php's true/false and declare them as boolean?
You often see in C++, some use Define().
Thanks.

Yes *true* and *false* are booleans.
PHP convert natively different types to boolean in order to help write
sentences like this
if( $object )
{
$object-something();
}
while( $data = mysql_fetch_assoc( $resource ) )
{
print_r( $data );
}
But we you try to print a boolean variable PHP convert it to string: true
becomes '1' and false becomes ''. That's why you can't just echo a boolean
variable to see the value, but you can rely on var_dump to show this.
$bool = true;
echo $bool;
var_dump( $bool );
$bool =! $bool;
echo $bool;
var_dump( $bool );
As other languages PHP as an special operator for checking types while
comparing values.
$a = 'false';
$b = true;
var_dump(
$a == $b, # -- true
$a === $b # -- false
);
This happens because values are converted before comparison so, 'false'
becomes true.
PHP converts everything different to an empty string as *true*
This also affect any type of variable.

The PHP_EOL is system dependent. If you want a solution that works on every
type of file you have to code it yourself. Here you have a function made
some time ago.
Maybe you can improve it.
If you want the result as a text format you can implode( PHP_EOL, $buffer )
Hope this helps you.
function explode($code)
{
$lines = array();
$buffer = '';
for($i=0, $len = strlen($code); $i$len; ++$i)
switch( $code{$i} )
{
case \r:
case \n:
if( $i+1 == $len )
break 2;
if( \r == ($next = $code{ $i+1 }) || \n == $next )
{
++$i;
}
$lines[] = $buffer;
$buffer = '';
break;
default:
$buffer .= $code{$i};
}
if( '' !== $buffer );
$lines[] = $buffer;
return $lines;

Thank you in advance, -behzad The best approach to shared sessions are, commonly, database driven, but this can vary depending on your site/network topology. If the two sites are in the same server (and the server is unique) you can share sessions, but this is risky, so you have to develop with this issue in mind, let's say avoid things like this. ?php $_SESSION[ 'something' ] = $somewhat; # you can be, probably, breaking the other app ? If you have more than just one web server, or you are planning to scale it later, then the database driven fits better. You need to share a cookie between both sites, often the session_id, and store the user-session info in a table. If the user logs-in -no matter in which site- an entry on the user-session table is set with the cookie and the user id. When the user logs-out this entry is removed, and the user is not able to navigate to private areas in both sites. Avoid doing things like a form-post from SiteA to SiteB. This kind of things only make holes to your application security system. User credentials MUST not be handled at client-side.

During a socket read, why would all the requested number of bytes
not
get sent? For example, I request 1000 bytes:
?php
$data = @socket_read ($socket, 2048, PHP_BINARY_READ);
?
This is actually in a loop, so I can get all the data if split up.
So,
for example, here's how the data split up in 3 iterations (for 1000
bytes):
650 bytes
200 bytes
150 bytes
But if I can accept up to 2048 bytes per socket read, why would it
not
pull all 1000 bytes initially in 1 step? Any thoughts on this would
be
greatly appreciated!
Because that's the way TCP/IP works, by design. TCP is a stream
protocol. It guarantees all of the bytes written to one end of the
pipe
will come out the other end in the same order, but not necessarily in
the same groupings. There are a number of buffers along the way that
might split them up, as well as limits on packet sizes in the various
networks it passed through. So you get what is available in the last
buffer when a timer expires, no more, and no less.
If you have serialized data that needs to be grouped in specific
blocks,
your application will need to keep track of those blocks,
reassembling
or splitting the streamed data as necessary. You could use UDP which
does guarantee that packets will be kept together, but that protocol
doesn't guarantee delivery.
Thank you for your input.
Is it guaranteed that at least 1 byte will be sent each time? For
example, if I know the data length...
?php
$input = '';
for ($i=0; $i$dataLength; $i++) {
// Read 1 byte at a time
if (($data = @socket_read ($socket, 1, PHP_BINARY_READ)) !==
false) {
$input .= $data;
}
}
return $input;
?
Or is this a completely unreasonable and unnecessary way to get the
data?
While I have written a lot of code to manage sockets over the years, and
coded a UDP/IP stack, I have never done it in PHP. And unfortunately, I
don't have time to experiment right now. My boss is waiting for the next
product release from me.
Getting one byte at a time is somewhat wasteful, as it requires more
system calls than necessary. That's a lot of wasted overhead.
Whether you always get one or more bytes depends on a number of factors,
including whether the calls PHP uses are blocking or non-blocking, plus
there may be ways to switch the socket back and forth.
Have you tried doing a Google search on the group of PHP functions you
expect to use. That should come up with some sample code to look at.
Bob McConnell
I agree that one byte at a time is wasteful. I'm sure others haven't
implemented something along these lines, but I wrote a much more efficient
way to make sure I grab all the data of a known length...
?php
function readSocketForDataLength ($socket, $len)
{
$offset = 0;
$socketData = '';
while ($offset $len) {
if (($data = @socket_read ($socket, $len - $offset,
PHP_BINARY_READ)) === false) {
return false;
}
$offset += strlen ($data);
$socketData .= $data;
}
return $socketData;
}
?
If not all the data is obtained on a read, it will loop until the amount of
data is the same as the length requested. This is working quite well.

2009/8/24 Szczepan Hołyszewski webmas...@strefarytmu.pl
Hi Lars and list!
New facts about the strange bug initially diagnosed as array() returning
NULL:
Firstly, the issue is not really about array() returning null, but about
full
blown UndefinedBehavior(TM) progressively trashing local variables. It just
so
happened that I noticed it first with a variable to which array() had been
assigned just before things began breaking.
Secondly, I proudly present the culprit: things break when I iterate over a
DOMNode's children *by reference* using firstChild and nextSibling:
for($child=$node-firstChild; $child; $child=$child-nextSibling)
{
//processing...
}
No problems if iteration is done by value or by DOMNodeList (childNodes,
DOMXPath...).
HOWEVER,
I still consider this a bug because it destablizes PHP. After the evil loop
has finished, things happen that should never happen, like a variable being
NULL immediately after being assigned array().
I attach a demonstration. It is a self-contained commented script that you
can
execute from command line. Also attached is output on my machine.
Best regards,
Szczepan Hołyszewski

Re: [PHP] session variables - help
(such
as
total cost); initially, this will have the calculated fields not
displaying
anything, and these will be (re)populated at each Update. Using this
method, all your values are contained solely within the $_POST array.
(ii) Have your initial form post to the process form, which then also
posts
to itself on Update. This process form will have visible fields only for
values which can be changed, but *must* then contain hidden fields for
all
the other values which were originally passed in the $_POST array. This
arrangement means that the process form always receives a full complement
of
values in the $_POST array -- either from the original form, or from
hidden
fields posted back to itself.
This is all just coming off the top of my head, and I'm sure there are
improvements/other solutions to be offered. Hope this will give you some
things to think about, and maybe a pointer or two towards a satisfactory
solution.

$time = strtotime( $i . ' day' );

$time = strtotime( $i . ' day' );
$fridays[] = date( 'Y-m-d', $time );

Here's my solution:
http://webbytedd.com/b/color-rows/
Cheers,
tedd
However, my solution (after reading others) is for an alternating row color
(a boolean operation).
The problem was NOT making every third row a different color or making
every row a different color. Those problems would require different
solutions.
There is nothing wrong with embedding php within html, which is really a
misnomer because it's the php interpreter that's sending the resultant html
to the browser. It is not sending php snip-its for the browser to handle.
So, embedding code such as:
tr class=row?php echo($i++ 1);?
Is a valid statement that works. It would be nice if you initialize the $i
value, but it will work either way.
My solution, provided via the above link, is a valid solution.
Cheers,
tedd

I see that from PHP 5.3.0 ereg_replace() function is deprecated and
throws a warning.
I would like to use the preg_replace() function as an alternative of
ereg_replace() function but...
can't undestand the \n#[^\n]*\n expression.
$sql = ereg_replace(\n#[^\n]*\n, , $sql);
Generally the only change you need to make for transition from ereg to preg
(for simple expressions, anyway) is the addition of pattern delimiters. So
the above becomes, for example:
$sql = preg_replace(|\n#[^\n]*\n|, , $sql);
Although I would argue that those \ characters should be escaped (and
should have been even for ereg), so the more correct version of this is:
$sql = preg_replace(|\\n#[^\\n]*\\n|, , $sql);

You can use a single quote string (instead of escape the \n)
The result is the same, but is more legible.
$sql = preg_replace('|\n#[^\n]*\n|', '', $sql);
Personally I try to not use double quoted.
PHP parses single quoted very much faster.
# for this
echo Hi, $name, wellcome $home;
# I use
echo 'Hi, ', $name, ', wellcome ', $home;

Aha! That must be what I tried and was still getting the notice!
Interesting that it works (without notice) if we check against the isset ()

This intelligence is given by the laziness of the operator.
$res = a() b(); # if a() is false then b() does not evaluate
$res = a() b(); # b() evaluates no matter a()'s result
so, order matters.

That's logically correct, and while PHP does implement this

Re: [PHP] navigation include not functioning
I think you are looking for something like this:

Then you MUST sanitize the $page variable.

echo $path = $_SERVER['QUERY_STRING'];

Re: [PHP] dynamically naming PHP vars on the fly?
You can use variable variables
?php
$nombre = 'Martin';
$name = 'nombre';
echo $$name; # === Martin
You can make more complicated statements with this technique.
$var1 = 'apple';
${ 'Fruit_' . $var1 } = 'organic';
echo $Fruit_apple; // here you are
When your statements are complex use the ${ statement } syntax.
I often use this for hidden global variables.
${ 'try to use this variable directly' } = 'something';
print_r( get_defined_vars() ); # [try to use this variable directly]
= something

Re: [PHP] Re: unsetting a referenced parameter in a function
I think he is confusing the unset semantic.
Unset just destroy a variable, but not the content of it.
Take a look at the output of this simple script:
function avoid_global_scope()
{
$a = 'foo';
var_dump( get_defined_vars() );
$b = $a;
var_dump( get_defined_vars() );
unset( $a );
var_dump( get_defined_vars() );
unset( $b );
}
avoid_global_scope();
This is the output in my apache2 / php 5.2.6... but yours MUST be the same
array(1) {
[a]= string(3) foo
}
array(2) {
[a]= string(3) foo
[b]= string(3) foo
}
array(1) {
[b]= string(3) foo
}
Note in the second array both variables was converted to references.
But in the third b is just a common variable.
This behaviour is cause by how PHP handles the references?
1) $a = 'foo';
Here we have an string 'foo' and a variable a which points to the string.
2) $b = $a;
Now we have anothe variable b which refers to _contents_ of variable a
Variable a is converted to a reference to it contents
3) unset( $a );
When a is destroyed only b refers to 'foo', PHP handles b as a common
var
3) unset( $b );
When b is destroyed PHP notes that no one is referencing 'foo'... so, it's
removed too.
Remember... unset destroy variables, not it's content.
class Foo
{
public static $last;
function __construct()
{
self::$last = $this;
}
}
$a = new Foo;
$a = null;
unset( $a );
var_dump( Foo::$last instanceof Foo ); # bool(true)

i think i'd have preferred compile error.
Well, you unset the reference and then you assigned 'meaning' to a local
function variable $a. Why would you get a compile error?
when you state it in those terms (which are clearly correct) i wouldn't.
but if the way i think is unset() destroys the specified variables (as
the
manual puts it) then i expect that the specified variable would be
destroyed, not the reference.
so, as i said, i was a bit surprised when the variable wasn't destroyed.
once i understood what was happening, i thought it a bit confusing to
have
such scope-dependent differences in behavior of a language element.
It might be easier to understand if you don't use the same var names:
function foo($arg) {
$arg = 42;
unset($arg);
$arg = 'meaning';
}
$a = 0;
foo($a);

You can use this simplest function to translate a string to camelCase.
The process could be...
1) parse by PHP
2) translate tokens to camelCase
3) writte the file with changes

You made a mistake in your code:

must be:
?php echo the_title(); ?

i think i'd have preferred compile error.
Well, you unset the reference and then you assigned 'meaning' to a local
function variable $a. Why would you get a compile error?
when you state it in those terms (which are clearly correct) i wouldn't.
but if the way i think is unset() destroys the specified variables (as
the
manual puts it) then i expect that the specified variable would be
destroyed, not the reference.
so, as i said, i was a bit surprised when the variable wasn't destroyed.
once i understood what was happening, i thought it a bit confusing to have
such scope-dependent differences in behavior of a language element.

The behavior of *unset()* inside of a function can vary depending on what
type of variable you are attempting to destroy.
If a globalized variable is *unset()* inside of a function, only the local
variable is destroyed. The variable in the calling environment will retain
the same value as before *unset()* was called.

If a variable that is PASSED BY REFERENCE is *unset()* inside of a function,
only the local variable is destroyed. The variable in the calling

Re: [PHP] Exception not being caught
There are many examples of error_handlers at

YOu can write a simple handler or a fully featured one, but the essence is
the same...

This does not run as expected. I'd think that when the implicit string
conversion in the try block hits, the exception would be thrown,
caught by the catch block, and relayed.
Instead you don't ever see the words exception caught and you get
Catchable fatal error: Object of class A could not be converted to
string.
If it's catchable, why isn't it caught in my example?
It's not an exception, it's a fatal error. Fatal errors are caught
by error handling functions, not by catch blocks.
Consequence of having (at least) two separate error handling
mechanisms in the same language.

Re: [PHP] Sub Menu System?
you can make the menu based on the files. Open the directory, read the files and save some sort of cache that use the site.

Thanks again everyone!!
Terion,
I hope that isn't your final answer. This has SQL injection written
all over it since you are neither validating that $letter is actually
a letter, nor are you escaping it before passing it off to MySQL.
?php
$letter = isset($_GET['letter']) ? $_GET['letter'] : 'A';
if (!preg_match('/^[A-Z]$/i', $letter) {
$letter = 'A';
/*
Rather than setting $letter to 'A' and continuing,
you could generate an error if you end up in here
so you can let the user know that what they passed
was invalid.
*/
}
//
?
In this case, it should be safe to use $letter directly in the query
without passing it through mysql_real_escape_string() since it should
only contain a single harmless alphanumeric letter, but it wouldn't
hurt (and may still be a good idea) to go ahead and escape the value
in the query anyway just in case something in your code changes later
that might cause some cruft to slip in.
Andrew
My point of view:
# i'll use constants for these values
assert( ord('A') == 0x41 );
assert( ord('Z') == 0x5A );
# 1. get the ascii code of the 1st character or from A=0x41
$letter = ord( array_key_exists('letter', $_GET) ? strtoupper(
$_GET['letter']{0} ) : 'A' );
# 2. different solutions
# 2.a check if it is range ussing = ussing constants (faster)
$letter = chr( 0x41= $letter $letter = 0x5A ? $letter : 0x41 );
# 2. different solutions
# 2.b check if it is range min/max and with constants (faster)
$letter = chr( min( max(0x41, $letter), 0x5A) );
I'd use the 2.b but this has different behaviour when $letter Z (should
this ever happen?)
In the other hand I think it is the faster one.
printf has it's own mini-syntax.
This was implemented in C.
PHP's printf syntax is very similar, but with some cool add-ons

But then he did say from memory -- use with caution. The general idea is correct. 2) It implements numeric pagination, which is usually based on a fixed number of rows per page. The OP wanted alphabetical pagination (like an address book) with each page containing all entries that begin with the selected letter. Andrew I just had a query doing the same thing one time, and that did take it's time (about 2-3 seconds) but it did have a few million records to look at, so I can understand why it was slow!

Re: [PHP] Scope of Variables and use of global and this-var
do you need to use global?
IMO you should use just 1 global variable, thats is what I call entry point
My scripts looks like...
require_once 'loader.php';
Loader::registerAutoload();
$foo = new Foo();
$foo-doStuff();
This way you can develop faster and do maintenance better avoiding
problems with third-party.
Here you have some rules for remember how to access
you want a $var from outside and you are outside an object or
function? = use the $var
you want a $var from outside you are inside an object or function? =
global $var o $GLOBALS['vars'] (better to pass it as arg)
you want a $var from an object and you are inside the same object? =
use $this-var (better $this-getVar() )
you want a $var from an object and you are inside other object? = use
$object-getVar() or Class::getVar()
It is a good practice to declare the object members as protected and
provide s/getters for each member (when your design allow it). Also
you can overload by using the __get, __set and __call

The :: is used to access static methods of a class. Static methods can
be used without creating an instance of the class because they dont
use any of the classes member variables.
For example say you have a class with a function for calculating the
area of a rectangle:
class SomeMathFunctions {
public function calculateRectangle($width, $height) {
return $width*$height;
}
}
To use this function you would need to first create an instance of the
class then call the method using the normal - :
$funcs = new SomeMathFunctions();
$area = $funcs-calculateRectange(10,15);
But if you create the function as static by using public static
function calculateRectangle($width, $height) {
then you can access the method by using just 1 call:
$area = SomeMathFunctions::calculateRectange(10,15);
So for creating utility functions its better to use static methods
since you dont get the overhead of creating a new instance of the
class.

If i commentize the header function i get a lot of strange simbols (such

The result of this code is a blank page. In Firefox the title sets to

He is actually re-assigning the var ussing the content of the var.

I have tried to get into the new version a few times, but it just seems so much more complicated to even set up a project in the new version and it seems like there are always updates to some component or other, many of which I do not use and some of which would not actually install. When I went looking for an IDE, I wanted a good code editor with features like syntax checking and code completion, and I wanted a debugger that I could step through code to figure out why something wasn't working as I expected. There were a couple that were close, but I chose Zend Studio at the time because it seemed to have the most complete/accurate code completion not only of the core language, but also recognizing functions and classes declared within the PHP code in the project itself (especially when you include a basic phpdoc block that describes the function @params and @return). Perhaps the new version still does all that wonderfully well, but as I said I've found it to be not worth the hassle. Perhaps, to be fair, I need to take some time to get familiar with the new paradigm, but that furthers my point: I want an editor that I can be productive with more or less out of the box.

foreach works on a copy of an array, so the behavior you saw is

See the online manual.
You could use a while loop, or, instead of unset-ing elements of

store the elements you want to keep into a new array.

For the moment, I am trying to resolve the problem of
extracting a value
from a string returned by a query. I thought that in_array() would do
it, but the tests I have run on it are 100% negative. The only thing I
have not used in the tests is third parameter bool $strict which only
affects case-sensitivity if the $needle is a string.
$strict has nothing whatsoever at all in any way to do with case
sensitivity -- $strict controls whether the values are compared using
equality (==) or identity (===) tests. As is stated quite clearly on the
manual page, in_array() is always case-sensitive.
This leads me to
believe that in_array() is either inappropriately defined in
the manual
and not effective on associative arrays
Complete rubbish -- the in_array() manual page is excellent and totally
accurate, complete with 3 working examples.
I would really like to understand why my attempts to reproduce the first
example just did not work.
Note also that the examples do not show in_array($string, $array)
My array was Array ([0]=6[1]=14), so when I tried if
(in_array($string, $array) , echo $string did not return 14 as I had
expected; neither did if(in_array(14, $array) ... nor if(in_array(14,
$array). It still does not... actually, the screen goes blank.
So, what am I doing wrong?
Here's what is not working... I'm trying to reproduce the example from
php.net:
$selected = array();
if ( ( $results = mysql_query($sql, $db) ) ) {
while ( $row = mysql_fetch_assoc($results) ) {
$selected[] = $row['id'];
}
}
print_r($selected);
$ex = 14;
if (in_array($ex, $selected)
echo br /yes;
else echo br /no;
Regardless if I put 14 into $ex or 14 or '14' or even if I put the 14
instead of the $ex into the if line, I get a blank screen. It seems tp
me, from what I see in the manual that this should work... or am I
supposed to know something that is not clear in the examples... ?

Everything is exaclty the same, but this one will not work. I have retyped
them, copied from those working, changed the name, changed the input
name...If I change the var to $zip, it works.
Any other suggestions?
Thanks again.

The center echo does not show. It will show if I replace $newmort with
anything else. I have copied the first if statement,pasted it in the
second position, and it works fine. Once I change the var to $newmort,
it
will not show. The third echo shows fine, it is only if I use newmort. I
have renamed the var from mort1, because I was getting the same thing.

$newmort=STRIPSLASHES($_POST['newmort']);
$purchprice=STRIPSLASHES($_POST['purchprice']);
$howlong=STRIPSLASHES($_POST['howlong']);
if ($purchprice) {
echo Purchase Price:$ $purchpricebr /;

the comment about use the !empty if you dont care about PHP.
if you don't care about PHP Notice...
eror_reporting:
http://us.php.net/manual/en/function.error-reporting.php
http://us.php.net/manual/en/errorfunc.constants.php#errorfunc.constants.errorlevels.e-notice
put error_reporting(E_ALL) on the begining of you page you will get errors,
warnings and notices - if any.
errors and warnings stop the execution of the code. notice not. notices are
usually about not defined variables before you started to use them.
if you put error_reporting(E_ALL ^ E_NOTICE) it will not bother you. but I
like to do everything correctly. :-)

But this is working, and unless someone sees a problem with it, I will
leave it as is.
Thank you to everyone for helping.

I have a form that gives the submitter a choice or either one set of
questions, or another. I am still getting the message even if the input was
left blank. So on the line below,
$msg.= isset($_POST['mort']) ? The mortgage amount is $mort\n : ;
I get
The mortgage amount is
What am I missing here?

Re: [PHP] Persistent data between two executions
You can use $_SESSION to store the object, and serialize to convert to string and reverse http://ar2.php.net/manual/en/language.oop.serialization.php // file one.php require 'user.php'; $user = new User(); $_SESSION[ 'user' ] = serialize( $user ); // file two.php require 'user.php'; // the class needs to be declared $user = unserialize( $_SESSION[ 'user' ] ); I think this is the cleanest way to do, but no the best performant. If you need performance you can use the interface serializable http://ar2.php.net/manual/en/class.serializable.php If you need a resources (like a db connection) you can implement __sleep and __wakeup in your class http://ar2.php.net/manual/en/language.oop.magic-functions.php On Wed, Jun 17, 2009 at 12:11 AM, James Colannino ja...@colannino.orgwrote: Hey everyone, Long time reader, not such a long time poster :-P (though I have posted to the list occasionally in the past...) Anyway, I have a general question for the list. Basically, I need to maintain persistent objects between page refreshes. So, for example, if while running a PHP script the first time I create an instance of class foo, the next time the script is run (when the browser reloads the page) I can again access that same instance of foo. I know that there's no way to truly do that, since a script only runs while generating output for the browser, but my question is, in the group's opinion, what's the best way to mimic this sort of behavior using temporary storage? Should I be using temporary files? I can think of at least a couple ways to do it, but I'd like to get some opinions as to best practice techniques, which take both security and relative efficiency into account. I would want to make sure that data isn't shared between multiple concurrent sessions, which would be a bad thing for what I'm doing. my oh-so-limited knowledge of PHP is shining through, I think :) Thanks so much!

Re: [PHP] Re: Dynamic Titles
PHP complains (usually) after the error.
1.
2. for( $i=0; $i10; ++$i )
3. echo $i, \n # missing ;
4.
5. unset( $i );
PHP will complain about unexpected T_UNSET at line 5
Why? Because PHP is expecting a anything different to unset.
So, when PHP says that an error was found at line x take a look at line x-1

Hello, im trying to make the CMS system im using more SEO friendly by
giving each page it's own title. Right now, the system assigns all pages
the same general title. I would like to use PHP to discertain which page
is being viewed and in turn, which title should be used.
I have put in the title tags the variable $title. As for the PHP im
using, I scripted the following:
$url = http://'.$_SERVER['SERVER_NAME']''.$_SERVER['REQUEST_URI']';
switch ( $url )
{
default:
$title = Photoshop tutorials, Flash tutorials, and more! Newtuts
Tutorial
Search; break;
case $config[HTTP_SERVER]help.php :
$title = Newtuts Help;
break;
}
Right now, im getting this error:
Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE,
expecting
T_STRING or T_VARIABLE or T_NUM_STRING in
/home/a7201901/public_html/includes/classes/tutorial.php on line 803
Can someone please help me with this?
Thanks!
I'm guessing that line 803 is
$url = http://'.$_SERVER['SERVER_NAME']''.$_SERVER['REQUEST_URI']';
which is full of mismatched quotes :-) Try any of
$url = http://{$_SERVER['SERVER_NAME']}{$_SERVER['REQUEST_URI']};
$url = http://.$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];
$url = 'http://'.$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];
Cheers
Also the line:
case $config[HTTP_SERVER]help.php :
probably won't work very well : should be either
case $config[HTTP_SERVER].'help.php':
or
case {$config[HTTP_SERVER]}help.php:
according to whether you like interpolation in quotes or not.
I recommend finding a development environment or editor that does syntax
highlighting - that would catch all of these problems before you even save
the file.

Re: [PHP] CURL intermittant problem
It looks like a connection problem, You has to make sure php can connect to the IP ?php echo exec( 'ping 10.20.30.40' ); ? You can remove the IP from the source, just add an entry in the /etc/hosts file Mrtn On Thu, Jun 11, 2009 at 8:14 PM, Daniel Brown danbr...@php.net wrote: On Thu, Jun 11, 2009 at 19:07, ioan...@btinternet.comioan...@btinternet.com wrote: The target URL works perfectly and quicly if put directly into the browser URL line. Do you know of any other reasons for problems with such a connection? Is the script being run located on the same system as which you're using the browser to (successfully) connect to the target host? If not, check to see if there's a network issue - a downed or improperly bound interface, SELinux restrictions, blacklisted by the remote machine, etc. - on the server on which the script it hosted. In addition, as simple and obvious as it is, if it's a private network, make sure the machine on which the script is hosted is within the same network as the target machine. -- /Daniel P.
