Operating system: windows2000
PHP version: 4.3.4
PHP Bug Type: Reproducible crash
Bug description: using str_replace() together with while chaches PHP
Description:
------------
When using str_replace() in a way it might not be thought (inside a
while-loop where the statement is the actual str_replace one...) for (but
still a valid one) it crashes php. This is 4 lines of code...
It just takes a while (less than a minute for me) before php actually
crashes. I have not seen any updates on this bug in 4.3.5 or 4.3.6...
Reproduce code:
---------------
$string="I hate double spaces.";
while ($string=str_replace(" "," ",$string)) {
$string=str_replace(" "," ",$string);
}
Expected result:
----------------
I expected $string to be: "I hate double spaces." I did not realise that
str_replace() did this without the while loop... So everything works like
a charm for me, but it might be problematic for other people?
Actual result:
--------------
A chrash... it takes a while and then apache restarts...
