Description:
------------
When i pass in ereg_replace a variable like this:

ereg_replace($pattern, $variable, $string);

and $variable is holding an integer value, then $string will be replace with blank, not the value hold in $variable. This only happen in Windows installation not Linux as i have used this many times.

Doing the following will fix the problem:

ereg_replace($pattern, (string)$variable, $string);

But does that mean PHP is now no long type tolerant?

Reproduce code:
---------------
$variable = 13;
$pattern = 'test';
$string = 'this is a test';
ereg_replace($pattern, $variable, $string);

Expected result:
----------------
this is 13

Actual result:
--------------
this is
