Regex pattern help

What would the pattern be for something like this?

#QUOTE_POST_123#

Where "123" is the post's id, which I'll need to grab out of that it.

Thanks in advance!

PCRE: #QUOTE_POST_(\d+)#
POSIX: #QUOTE_POST_([[:digit:]]+)#

Something like that.

Hmm,

It's not recognizing the #'s. If I put QUOTE_POST_123 it still works.

Edit: Here's my current code:

Code:

if(preg_match('/^#QUOTE_TOPIC_([[:digit:]]+)#$/', $topic_body, $matches))
{
$found = $matches[1];

$topic_body = preg_replace('/^#QUOTE_TOPIC_([[:digit:]]+)#$/' , $forum->find_quotes_and_replace($found , TOPIC) , $topic_body);
$topic_body = preg_replace('/^#QUOTE_TOPIC_([[:digit:]]+)#$/' , '' , $topic_body);
}

With the /^ and $/ it's not recognizing it at all.

v3x0rg: Mind posting what you did so other future users who may come across this thread will know a solution?

PHP:

<?php

/**
 * A Valid pattern to match the digits of a string and ONLY  the digits, if preg_match_all is used, the search will be repeated through the string.
 */
// '/([[:digit:]]+)/'

// Explanation
'/
    ( # Begin our sub patern
        [ # Begin our character class
                [:digit:] # We are only conerned about digits
            ] # End our character class
        + # add the + quantifier to match as many digits asneeded
    ) # End our sub pattern
/'

?>

Not tested but quality assured just a explanation for other forum posters and im bored

ringpull: Here's my code:

PHP:

<?php
        function find_quotes_in_post($id , $post_body , $type = NULL)
        {
            if($type != NULL)
            {
                $query = "SELECT * FROM forum_" . (($type == TOPIC) ? "topics" : "posts") . " WHERE id = '" . $id . "'";
                $result = mysql_query($query) or die(mysql_error());

                $str = "";

                if(mysql_num_rows($result) > 0)
                {
                    $row = mysql_fetch_assoc($result);

                    $poster_id = $row["posterid"];
                    $body = $row["body"];
                    $stamp = $row["timestamp"];

                    $date = date("F j, Y, g:i a" , $stamp);

                    $str .= "<div class=\"quote\">";
                    $str .= "<img src=\"images/paper_folded2.gif\">&nbsp;Posted by <b><a href=\"#\">" . name($poster_id) . "</a></b> - " . $date . "<br \><br \>";
                    $str .= $body;
                    $str .= "</div>";
                }

                $strings = array();
                $replace = array();

                preg_match_all('|#QUOTE_TOPIC_(\d+)#|', $post_body, $matches, PREG_SET_ORDER);
                foreach($matches as $match) 
                {
                    $strings[] = $match[0];
                    $replace[] = $str;
                }

                $post_body = str_replace($strings, $replace, $post_body);

                unset($strings);
                unset($replace);

                $strings = array();
                $replace = array();

                preg_match_all('|#QUOTE_POST_(\d+)#|', $post_body, $matches, PREG_SET_ORDER);
                foreach($matches as $match) 
                {
                    $strings[] = $match[0];
                    $replace[] = $str;
                }

                $post_body = str_replace($strings, $replace, $post_body);

                return $post_body;
            }
        }
    }
?>

I sort of gave up on this idea though. If you want to suggest any changes to my code, please do so

P.S. I don't think it works 100% though.

The ##'s were delimiters for the regex, I should have been more specific.

PHP:

<?php

preg_replace('#^QUOTE_TOPIC_(\d+)$#', $forum->find_quotes_and_replace($found, TOPIC), $topic_body);

?>

preg == PCRE
ereg == POSIX

Read up, mate.
