incremental str_replace...help!!

[Guest_imported]

hi,
i need some help doing a find and replace on a text string. I want to replace every instance of "%0D%0D" with "&value$i=" within the text string, where $i is a number that increments for each replace.

This is the code I'm using at the moment:

for ($i=0; $i<substr_count($string,&quot;%0D%0D&quot; $i++)
{
$new_string = str_replace (&quot;%0D%0D&quot;, &quot;&value$i=&quot;, $string);
}

There are 5 instances of &quot;%0D%0D&quot; in the text string. With the above code it does replace all the &quot;%0D%0D&quot;'s to &quot;&value$i=&quot;, but they all read as &quot;&value5=&quot;. But I need them to read: &quot;&value1=&quot; for the first instance of &quot;%OD%OD&quot;, &quot;&value2=&quot; for the second instance of &quot;%OD%OD&quot;, and so on up to &quot;&value5=&quot;.

Any ideas??

thanks,

jc

set the count of the strings matched to a different variable cos at the moment you say $i=0 then $i=5 (count of strings matched)

$i=0;
$counter<substr_count($string,&quot;%0D%0D&quot;
while ($i <= $counter)
{
$new_string = preg_replace(&quot;%0D%0D&quot;, &quot;&value$i=&quot;, $string, 1); // replaces one at a time
$i++;
}

hi, thanks for the reply. When I try that I get the following error:
Warning: Unknown modifier '0' in /

http://www/test.php

on line 28

line 28 is:
$new_string = preg_replace(&quot;%0D%0D&quot;, &quot;&value$i=&quot;, $string, 1);

any ideas??

thanks again!

oh yeah, % is a special character , delimit it with \ and things may look better ***************************************

OK after beating my head against the door for a few hours I figured out why it wasn't working for me ...

Note: Parameter limit was added after PHP 4.0.1pl2.

but.. if you have later version then this should work:
$string = preg_replace('/%0D%0D/', &quot;&value$i=&quot;, $string,1); // replaces one at a time ***************************************

$i=1;
$counter=substr_count($s,&quot;%0D%0D&quot;

$string = preg_replace('/%0D%0D/', &quot;&value$i=&quot;, $string, 1);
