Jason is right. $v = preg_replace('/\$[0-9]/', '\\\\$0', $v);Should work. $12
to him. To also protect against \\12.50in your data the best I can do is
follows./jm<?php # you need this while developing!error_reporting(E_ALL); #
init test vars$v='One $, $12.50 \\12.50 \\\\12.50 \1'; print $v;
$ff='something';$newpage['text']='text with (:something: value:) embedded'; #
the essential bit $v=str_replace(array('\\','$'),array('\\\\','\$'),$v);if
(strpos($newpage['text'], "(:$ff: ") !== false) # not needed at all,
complicates your code (Kathryn is your friend) $newpage['text'] =
preg_replace("/\\(:$ff: (.*?):\\)/s", "(:$ff: $v:)", $newpage['text'], 1);
print " <br/>\n$newpage[text]"; exit;From: [EMAIL PROTECTED]: [EMAIL

I'm now busy resolving your problem. Before starting there are a few problems
with your code upfront:> if (strpos($newpage[text], "(:$ff: ") == true)
$newpage['text'] = preg_replace(> '/\\(:'.$ff.': (.*?):\\)/s',
"(:$ff: $v:)", $newpage['text'], 1);1. Do this in anything you are developing:
error_reporting(E_ALL); # let PHP help you2. strpos returns either false
or a number. Don't test for 'true', test for ' !== false ' (note this isn't '
!=false ' )strpos($newpage[text], "(:$ff: ") == true 3. Use quotes as in
$newpage['text'] (point 1 would have helped you here). Now getting to the
regex part. Seems like you have to preg_quote()/jm > > On 4/9/07, The Editor
