[PHP] preg_match_all problem
Hi,
Below is my code for a templating kind of script, it basically searches for
'tags' like this {movies 30} and replaces them, the problem is that if there
are 2 tags (eg: {movies 30}{movies 60}) it only replaces the first one...so
I tried using a preg_match_all...
I tried using a preg_match_all at:
preg_match($pattern,$content,$matches[]);
but then $res is blank when $res usually contains the tag names... (using a
print_r($res); I just get Array ( [0] = Array ) )
**Start of code*
$categories=array(movies,action,cartoons,textlinks);
// This gets the tags and put it into matches[]
foreach ($categories as $value)
{
$pattern = /{.$value. ([0-9_]+)?}/;
preg_match($pattern,$content,$matches[]);
}
foreach ($matches as $key =$value){
preg_match(/\w+/,$value[0],$res);
//print_r($res);
***End of code*
What am I doing wrong?
Thanks,
Ryan

I see where things are being matched, but how are they being replaced? What you really
need here is preg_replace_callback(), probably.
?php
$result = preg_replace_callback('/\{([a-z]+) ([0-9]+)\}/i','callback',$yourtext);
function callback($matches)
{
//$matches[1] is movies, cartoons, textlinks, etc
//$matches[2] is the number that was matched
//this function should return the string to replace
//{movies 20} {cartoon 10}, etc...
}
?

From: Ryan A [EMAIL PROTECTED] $content = str_replace($matches[$index][0],$value,$content); If you are interested in seeing the whole script, just scroll down. I'm not... but thanks. Did you read what I wrote? using preg_match twice and then str_replace is a waste. Learn to use preg_replace_callback() to make this worthwhile. ---John Holmes...

[PHP] Preg_match_all problem
Can anyone see why I'm getting this error message:
Warning: No ending delimiter '^' found in
C:\Inetpub\wwwMIS_DEV\import_mvs.inc.php on line 126
From this line:
if(preg_match_all(^([00])?.*$,$called,$found))
{
substring($called,2,9);
}
I basically have a phone bill that sometimes has the phone number
preceeded by 00 and sometimes not.
When it has the 00 I want to trim it with the substring command.
Thanks,
Jeff

You need to enclose your regex in /regex/
if ( preg_match_all ( /^([00])?.*$/, $called, $found ) )

In fact, you don't have a starting delimiter, either, but preg assumes you meant the ^ character to be your delimiter. This is explained in all of the examples in the manual, but you must surround your regular expression by a delimiter such as the / or # character. This is because you can include modifiers after the delimiters to further create your regex. if(preg_match_all(/^([00])?.*$,$called,$found)) Although I doubt that'll work like you want it since [00] matches a zero, or another zero. It only matches one character. I basically have a phone bill that sometimes has the phone number preceeded by 00 and sometimes not. When it has the 00 I want to trim it with the substring command. I wouldn't even use preg for this. Just use ltrim() or if(substr($called,0,2)=='00')... ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] preg_match_all problem
Hi, I'm a frog (french),
I,ve some troubles with the preg_match_all function.
input type=TEXT name=search maxlength=50 size=36
$strSearchWords = Trim($search);
$pattern = $strSearchWords;
andwhile (!feof($openFile))
{
$strFileContents .= fgets($openFile, 4096);
}
$strPageTitle = htmlentities(GetFileMetaTag(title,
/title, $strFileContents));
$strPageDescription = htmlentities(GetFileMetaTag(meta
name=\description\ content=\, \, $strFileContents));
$strPageKeywords = htmlentities(GetFileMetaTag(meta
name=\keywords\ content=\, \, $strFileContents));
$strFileContents = $strPageTitle. .$strPageDescription.
.$strPageKeywords;
$strFileContents = str_replace(; , ,$strFileContents);
$strFileContents = str_replace(,, ,$strFileContents);
then I get the following warning message:
Delimiter must not be alphanumeric or backslash in :
if (preg_match_all($pattern,$strFileContents,$match) 0)
WHAT CAN I DO ???

I had this problem only a day ago. You have forgotten to add slashes to
your pattern. The variable $pattern looks something like this:
\d+\s
when it should look like this:
/\d+\s/
Hope that was helpful,
