You should know that, unless you tell php to limit the number of replaces, it
will keep on replacing until it doesn't find a match anymore.

Here is what happens:

<?php
$texte = 'cd' ;
$original = array('a', 'b', 'c', 'd', 'e', 'f', 'g');
$modif = array ('c', 'd', 'e', 'f', 'g', 'h', 'i');
$texte = str_replace($original, $modif, $texte) ;
#after first replacement
$texte='ef'
#after 2nd replacement
$texte='gh'
#after third replacement
$texte='ih';

If you want to prevent this, tell the function that you only want 2
replacements. Like this:
$limite=2;
$texte=str_replace($original,$modif,$texte,$limite);

Hope this helps

With kind regards


ps: the php documentation is also available in French. Check out:

str_replace
