If you're expecting the statement
Echo Foo::getUs();
To echo me me it will not because you never returned $us from the
getUs() method. I'm assuming also that xxx is a variable to mean some
class library correct?

I have a class that won't be instantiated...so basically just a bunch
of static methods.
How do I call one of the class' static methods from within another
method? Can't use this, and self doesn't work...this is php4.
Thanks.

I'm sure I could test it and maybe find out if it works but is it
documented behaviour I can rely on? I'm sure not finding this in
the
manual now that I go looking for it, though I know I saw it there
before.
I would think it would be just fine *EXCEPT* that the internal
pointer of the original array is being incremented in parallel with
the copied array key/values, so it ends up at the end after the
foreach
So, unless it's a DOCUMENTED FEATURE rather than an implementation
detail, I don't really want to rely on unset($original[$k]) working
because who knows what might change in PHP6 with the internal
pointer and unsetting the current entry it points to, or, rather, the
entry it previously pointed to.
I know for sure that while/list/each and an integer-indexed array and
(unset($array[$k + 1])) is a big mistake :-)
I would *think* (just my opinion without much thought on a Friday
morning)
[PHP] Referencing Containing (Non-Parent) Object?
I'm trying to figure out if PHP has the facility to reference containing,
non-parent objects. I have three classes, embedded hierarchically, but which
are NOT extended classes of their containing objects. I'd like to be able to
reference variables in the higher-level objects from the lower-level objects.
To illustrate:
?php
class Country {
var $name;
var $states;
function Country($name = '', $states = array()) {
$this-name = $name;
$this-states = $states;
}
}
class State {
var $name;
var $cities;
function State($name = '', $cities = array()) {
$this-name = $name;
$this-cities = $cities;
}
}
class City {
var $name;
fuction City($name = '') {
$this-name = '';
}
function name_with_state() {
return $this-name, . /* parent node reference */-name;
}
}
$countries = array (
'USA' = new Country('United States',
array (
'WA' = new State('Washington',
array (
'SEA' = new City('Seattle'),
'GEG' = new City('Spokane')
)
),
'CA' = new State('California',
array (
'LAX' = new City('Los Angeles'),
'SFO' = new City('San Francisco')
)
)
)
)
);
echo $countries['USA']-states['WA']-cities['SEA']-name_with_state();
// Output: 'Seattle, Washington'
?
Obviously, just extending Country doesn't make sense: a State isn't a type of
Country, and a City isn't a type of State -- but States are part of Countries,
and Cities are part of States. Plus, if City was just an extended State (which
in turn is an extended Country), it would contain both a $states and a $cities
variable. Which doesn't make sense.
What, if anything, do I replace /* parent node reference */ with in
City::name_with_state()?
Thanks,
Morgan

A bit off-topic but important: Always make sure that you check the
contents of $value1 and $value2 before putting them into the query!
With
$value1 = 'xyz,xyz); DELETE FROM MYTABLE;';
you might get surprising results!
This is called SQL injection and it's important to escape all the values
before putting them into the statement.
Did you try that? This doesn't work on my machine:
mysql_query(DELETE FROM mytable; DELETE FROM mytable;);
ie, mysql extension won't let me do more than one statement at a time.

[PHP] Images outside webroot + session = safe?
Hi there,
I am storing images outside the webroot to keep them from being accessible
for unauthorized users to see.
Then I use a script to show the images, like this:
img src=show.php
Now, as there is no information on the images stored in a database yet (they
have just been uploaded via ftp), I need to find a way of passing the
information as to which image is to be displayed.
I am currently trying out this way:
1. I read the filenames for all images in the upload directory into an
array.
2. I store that array in a session variable.
$_SESSION['images'] = $this-image_array;
3. I call show.php passing an array key:
img src=show.php?id=xy
4. In show.php I start the session, get the image information from the
session array, check if the mime type is okay and then display the image.
Of course I still need to add user authorization...
Any opinions on how safe this method seems or how it could be made
safer/more efficient? Do you think this method could be exploited to
compromise the server in any way?
Here the listing for show.php
?php
session_start();
$file = $_SESSION['images'][$_GET['id']];
if(is_file($file['path'].$file['file'])) {
//determine mime type and imagetype
$tmp = getimagesize($file['path'].$file['file']);
$file['mime'] = $tmp['mime'];
//if file is of valid type - output to browser
if(in_array($file['mime'], $_SESSION['conf']['images']['allowedtypes'])) {
header(Content-Type: .$file['mime']);
header(Content-Disposition: filename=.$file['name']);
readfile($file['path'].$file['file']);
}
}
?
Any comments are appreciated.

Well, somewhere in the said manual it is written that foreach operates
on a *copy* of the array, so you should be safe unsetting values in the
original array while iterating through the copy.

I suspect you want the functionality of Java embedded clases, where
embedded class can access fields of its container. If that's what you
mean, then sorry, PHP doesn't have that. You would have to keep a
reference ro parent object as a variable in child object, ie your City
should have a var $_state variable, etc.

[PHP] Sessions and register_long_arrays
Strange behaviour that's taken me ages to track down. I have the situation where I can create a session, but any changes to it are not saved. session_write_close() didn't help. Eventually I tracked it down: if you have register_long_arrays disabled (as is the default in PHP5), this can happen. Enabling it fixed the problem. A very simple test case didn't show this problem, so I guess something in my sessions has a dependency on HTTP_GET_VARS or similar, though these old-style vars do not appear anywhere in my code... Some of the libraries I'm using may use them (for example Smarty, though I have the request_use_auto_globals option enabled for that which should stop it using them), but nothing to do with them is stored in the session. If I look at a session file, it's all just scalars and arrays, no complex types at all, but changing an item in $_SESSION simply does not get saved back to the session file if register_long_arrays is enabled. Anyone else seen this? Any idea why it might be happening?

I've also tried using it with the mm session save handler and I get the same symptoms. I also get identical results on OS X and Linux. FYI, I want to disable this setting for increased performance, especially as I'm not using these old arrays anyway.

Re: [PHP] [DONE] Substr by words
Good job!
However, let me give a few suggestions to optimize the code
function trim_text($text, $count)
{
$text = str_replace( , , $text);
/*
* This is redundant; you are replacing all in $text with
* maybe you meant
* $text = trim($text); ?
*/
$string = explode( , $text);
/*
* For better programming practice, you should initialize $trimed
* I believe if you turn on error_reporting for all in php.ini
* PHP will display all warnings and errors.
*/
for ( $wordCounter = 0; $wordCounter = $count;wordCounter++ )
/*
* Typo - you forgot the $ for wordCounter++
*
* for ( $wordCounter = 0; $wordCounter = $count; $wordCounter++)
*/
{
$trimed .= $string[$wordCounter];
if ( $wordCounter $count )
{
$trimed .= ;
}
else
{
$trimed .= ...;
}
}
$trimed = trim($trimed);
return $trimed;
}
This is purely my suggestion... and I'm not saying it is better... but
if I were you, I'd do it this way :
function trim_text($text, $count)
{
$text = trim($text);
$string = explode( , $text);
$trimed='';
for ( $wordCounter = 0; $wordCounter = $count; $wordCounter++ )
{
$trimed .= $string[$wordCounter].' ';
}
$trimed = trim($trimed);
if (count($string)$count)
$trimed.='...';
return $trimed;
}
The only difference(not that you'd notice in a lightweight routine like
this) is that, I don't have that if-else block inside the loop.

Re: [PHP] [DONE] Substr by words
Good start guys. That's usually how I start down the path in solving a new
problem. Invariably down the road I find a more refined way of doing what I
did the hard way. The hard way is good though, you learn stuff along the way.
Let's see how tight we can make this though:
?php
$string = This is a test string of some sort. ;
$truncated = truncstr($string);
echo $truncated;
function truncstr($tmpstr) {
$maxwords = 4;
$tmpstr = trim($tmpstr);
$wordarr = explode( , $tmpstr);
if (count($wordarr) $maxwords) {
$wordarr = array_slice($wordarr, 0, $maxwords);
$tmpstr = implode( , $wordarr) . ...;
} else {
$tmpstr = implode( , $wordarr);
}
return $tmpstr;
}
?
Or if you want really obfuscated code...
?PHP
$string = This is a test string of some sort. ;
$truncated = truncstr($string);
echo $truncated;
function truncstr($tmpstr) {
return implode( , array_slice(explode( , trim($tmpstr)), 0, 4)) . ...;
}
?

So, if there is any php code in the include, you can't rely on the include being inside a php block. You must put a php block inside the include as well.

Re: [PHP] Retrieve Data Formated from Text field
The data is inserted into db in this way: Hello, This is a sample of first line. This is another paragraph, blah blah blah Bye But the result is in one paragraph: Hello, This is a sample of first line. This is another paragraph, blah blah blah Bye It sounds as if your database record includes a carriage return or new line character (\n), which is not recognized in html (except using the pre tag. You need to replace the new line with an html p tag. You might want to store each paragraph in a different database record (make a table for the text. It will include a key that connects it to the main record, the text, and a sequence number that tells you the order in which the paragraphs should be displayed).

Re: [PHP] is there a number translation function?
I couldn't find one out there Linda (and I'm sure I've seen them before) so
since I'm stuck at work on a Saturday I thought I'd take a break and see if I
could hack this out myself.
Probably a more elegant way to do this, but here's what I came up with. Feel
free to use and modify it at will.
It should be infinitely expandable by adding to the $places array. (well,
'infinite' in regards to your system's ability to handle long strings, no long
ints or floats are used so that shouldn't limit it).
Let me know if you have any questions or if anyone can improve this (always up
for learning new tricks :)

Hi,
Does anyone know of a function for translating a decimal number into an
English number. In other words, if you pass it 1 it will return 'one', if
you pass it 127 it will return 'one hundred twenty seven', and etc.
Thanks,

Keep in mind that the pipe between your database and PHP is a rather small narrow expensive opening. Sucking down your ENTIRE description field to throw away all but 50 characters may not be the best use of limited resources. [This is all MOOT if you have no dreams of your site being big some day.] You therefore may want to consider something like: select substring(description, 1, instr(description, ' ', 50)) as description_50, substring(description, instr(description, ' ', 50), 1) as more from ... $description_50 will be 50 chars, more or less $more will tell you if there was more or not You will only be getting ~50 characters squeezed through that narrow expensive db - PHP pipeline. I believe that in MOST PHP/database applications this is going to be a better performing solution, and it's somewhat cleaner aesthetically than shoveling a bunch of data around that you're going to discard anyway. * instr may or may not be the right function in your database.

It was probably replacing *TWO* spaces with one.
If so, it should really be in a while loop, because there could be 3
or more spaces in a row, and if the goal is only single-spaced
words...
//Replace 2 spaces with 1 until all words are single-spaced
while (strstr($text, ' ')) $text = str_replace(' ', ' ', $text);

My post was doing 50 LETTERS, not 50 words.
So change 50 to 250 and call it done. :-)
Unless the word-count is really that critical...

Is it possible to loop through all $_POST values to see if it is a
checkbox?
If so then for that element if it is equal to 'on' then change it to 1

No.
The only things you get in POST are:
name (string)
value (string)
PHP does provide the feature (some call it mis-feature) of array
processing on name, so that:
name[index] turns into $name['index']
If you want to identify your checkboxes as checkboxes, you will need
some external, application-specific way to do so.
You could:
#1. Use Hungarian Notation (ugh!) in your checkbox field names, so you
would know that any 'name' that starts with 'ckbx' was a checkbox.
#2. Have an array of known checkbox fields in your PHP
?php
$checkboxes = array('spam_me', 'read_terms', 'whatever');
?
And then you could compare each $_POST index with that array.
Improving performance using $checkboxes with KEYS of the names instead
of values is left as an exercise for the reader :-)
You also need to be aware that HTTP does *NOT* transmit off checkboxes.
If the user has 3 checkboxes, and selects only 1, you get *NOTHING* in
$_POST about the other 2 checkboxes.
The very lack of any POST data tells you the checkboxes are off
So you will most likely be using isset($_POST['checkbox_name']) rather
than testing for on

Re: [PHP] Re: Type of form element
I usually place a hidden field with the same name as the checkbox
field before the actual checkbox field. I store my 'false' value in
there. If the checkbox is checked the hidden field is overridden.
?php
error_reporting( E_ALL );
if( isset( $_POST[ 'submit' ] ) )
{
echo 'pre';
print_r( $_POST );
echo '/pre';
}
echo EOF
form method='post' action='$_SERVER[PHP_SELF]'
input type='hidden' value='0' name='blah'
input type='checkbox' value='1' name='blah' Blah?
input type='submit' name='submit'
/form
EOF;
?
This probably works just fine in all browsers, but...
I don't THINK the HTML and HTTP specification specificially require
ordering of HTML/INPUT/POST elements to match up
In fact, as I recall (and it's been YEARS since I read the damn thing)
I believe they specifically said that the ordering was NOT to be
relied upon...
Though this may well have changed in HTTP/HTML 3.0, 4.0, XHTML, etc
vesions of specifications.
It also seems like rather needless bloat of HTML, to me, unless I'm
missing something.
$blah = isset($_POST['blah']);
//update or process $blah
If the processing of $blah is particularly expensive or heinous, and
it's a pre-existing preference type of setting, I can see the savings,
but given the overhead of checking every value going in/out to compare
before update, it seems like the overhead outweighs the savings, and
clutters up the code...

Now, out of all that, the only thing expensive is download.php coming off the disk drive. If you have a PHP Cache of some kind (Zend Cache, et al) then this is cheap.

But you get the idea. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Script Multitasking
Hi, I have a file, which I run using command line. The file I am running, runs several files using passthru(). What I realise is, that it runs each file in sequence and waits for its result. I need to run all files at once and they don't have to return the result to the main file. How do I do this? Any help appreciated!

Couple Options: Change your script to accept a single filename from the command line ($argv) and then run several of that script from command line in the background: php -q singlefileprocess.php datafile1.txt php -q singlefileprocess.php datafile2.txt php -q singlefileprocess.php datafile3.txt http://php.net/pcntl This basically would be the same (sort of) as just running multiple copies of your PHP script, one for each file, but keeps your script able to process multiple files... Not sure it's worth the effort, but there it is. You could also use http://php.net/exec to have PHP fire up more PHP scripts in the background: ?php //loop through $filename exec(/full/path/to/php -q processonefile.php $filename , $output, $error); if ($error) echo OS Error: $error\n; echo implode(, $output); if ($error) exit; ? Note that in all cases, not only with the results most likely not return to the main file, they'll be reading the files in parallel and doing whatever to them... Be sure that this won't affect other parts of the application. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Re: Substr by words
Hello.
What do you think about this:
?php
$MyOriginalString = This is my original string.\nWhat do you think
about this script?;
$MaxWords = 6; // How many words are needed?
echo substr( $MyOriginalString, 0, -strlen(ereg_replace
(^([[:space:]]*[^[:space:][:cntrl:]]+){1,$MaxWords},
,$MyOriginalString)));
?
Only 3 lines.
You have to change $MaxWords to 50 if that's what you need.
Best regards,
Gustavo Narea.

Hi,
I need to extract 50 words more or less from a description field. How can i
do that?. Substr, cuts the words. Is there any other way to that, without
using and array? I mean and implemented function in PHP 4.x
I´ve been googling around, but wordwrap, and substr is driving me mad...
Thanks in advance
Best Regards

If forgot to say that It counts ($MaxWords) words, It doesn't matter if
they're separated by simple spaces, line feeds (Unix, dos or mac), tabs,
among others.
On the other hand, you won't have any problem if you use non-English
characters.
