Replace only once

[IWeb]

Hello!

I want to replace a string within a string on the first position.

e.g.:

$a="this is my something and another something is...";

I want only to replace the first time "something" occurs in the string.

How can I do this?

thanks

Should it work with "preg_replace" ?

You could do it with REGEX if you want. Here is a not-so-elegant solution without REGEX though.

<?
$mystring = "this is something this is something";
$to_be_replaced = "something";
$replace_with = "[replaced]";

echo $string = substr_replace($mystring, $replace_with, strpos($mystring, $to_be_replaced), strlen($to_be_replaced));
?>

would output:

this is [replaced] this is something

I am sure the REGEX gods will flame me, but this should get you started.
