Your regex wont work.

Your trying to match || followed by a space at the end of the string.

Where you have space then the double pipes in $string.

Using
------
$string = "ship_id = '17' ||";

$string = preg_replace("/ \|\|$/", "", $string);

echo $string;

I get no
ship_id = '17'
as exepcted

Description:
------------
There seem to be some major issues with preg_replace in this version.

See code actual and reproducable for explanations

Reproduce code:
---------------
$string = "ship_id = '17' ||";

$string = preg_replace("/\|\| $/", "", $string);

echo $string;

Expected result:
----------------
SHOULD result in

ship_id = '17'


being printed to the screen.

Actual result:
--------------
PHP crashes.
Indeed it would seem absolutely anything i enter as either the regexp,
or the string will crash it. Even if both are blank.


Below is the 'details' of the error (as gained from windows thing):

But the regexp DOES work with 3.4.2!!! And earier version too.

What the regexp ("/\|\| $/") does is:

\|\| = looking for ||

" " = looking for space

$ = the above must be at the end of the string


No piping or anything else required there.

And the string it's replacing is something more like:
$del_str .= "ship_id = '17' || "; (with an extra space at the end (typo
my missing it out on the original post)). That'd be why you thought it
wouldn't work. Sorry. ;)
