Question : PHP: Find and Replace only 1st occurance

I want PHP to go through my string and only replace the first occurrence of the words I want replaced.  str_replace seems to replace every occurrence, I just want to have the 1st occurrence replaced.  How can I go about doing this?

Answer : PHP: Find and Replace only 1st occurance

Use preg_replace ...here is an example..


<?
$var = 'abcdef abcdef abcdef';
// pattern, replacement, string, limit
echo preg_replace('/abc/', '123', $var, 1); // outputs '123def abcdef abcdef'
?>
