Description:
------------
The str_replace and str_ireplace functions seem to be malfunctioning. Instead of returning the expected result, it adds the subject paramater to the end of the search parameter and returns that.
 
Any thoughts? I'd really appreciate anyone's help.
 
Thanks,
Clint
 

Reproduce code:
---------------
<?php 
 
$bodytext="one two three four five six seven eight"; 
echo $bodytext; 
 
$searchtext="three"; 
$replacetext="(two again)"; 
 
$bodytext = str_replace($bodytext, $searchtext, $replacetext); 
 
echo $bodytext; 
 
?> 

Expected result:
----------------
one two (two again) four five six seven eight

Actual result:
--------------
one two three four five six seven eight(two again)
