New Comment:
reviewed preg_replace string again and realized two non-alphanumeric
characters were not escaped. (specifically two "(" ) re-ran and now the
preg_replace string works. this must have been a change in 5.2.5 but now
that the ('s are escaped the function works properly.

EDIT:
"<img src=\"./skin/$skinname/emotes/crazy.png\"
src=\"./skin/$skinname/emotes/crazy.png\" alt=\"crazy\"
title=\"crazy\">"
should be "<img src=\"./skin/$skinname/emotes/crazy.png\"
alt=\"crazy\"
title=\"crazy\">"
preg_last_error(); returns 0 NO_ERROR.
why is this function not working as expected?

Description:
------------
preg_replace blanks a string that it didn't use to in previous versions
of PHP 5.x. other preg_replace strings not affected
Reproduce code:
---------------
function doSmiles($string, $skinname)
{
$patterns = array(
"/\[alien\]/i",
... snipped due to length ...
"/\[crazy\]/i"
);
$replacements = array(
"<img src=\"./skin/$skinname/emotes/alien.png\" alt=\"alien\"
title=\"alien\">",
... snip due to length ...
"<img src=\"./skin/$skinname/emotes/crazy.png\"
src=\"./skin/$skinname/emotes/crazy.png\" alt=\"crazy\"
title=\"crazy\">"
);
$string = preg_replace($patterns, $replacements, $string);
return $string;
}
Expected result:
----------------
print substrings like [alien] to html-valid strings like <img
src="./skin/default/alien.png">. prior to upgrading to 5.2.5 this
particular function DID work. it no longer works.
Actual result:
--------------
returns a blank string ""
