Old-Status: Closed
Status: Open
Bug Type: Scripting Engine problem
Operating system: RH Linux 6.1
PHP Version: 4.0.4pl1
Description: For loop always execute
I have solved the problem in another way. BUT; The value of $c *IS* 0 when entering
for loop and the stange behavior of the for-loop explained above happens. I think it
maybe is other part of the code BEFORE this function who make som "crash" in the
system so this happen. I've never seen this before neither after so i dont know what
more to say :)
But for sure it was a strange behavior of PHP in this code. We are two persons coding
this system and we both spent a lot of time trying to find out what happens (with echo
and other debug code) but we could'nt find out.
We had to drop the for-loop because it didnt work as it should.

I have spent twenty mins trying to recreate this, before you start your for loop
please check the value of $c (echo it out etc) and make sure its what you expected. I
very much doubt this is a bug, if the value of $c is indeed 0 then please reopen this
report.

I'm sorry, but all other script i make work ok. Its just this one that cause the
problem.
I dont know how to make another script for you as i cant reproduce the error in any 5
line of code.

I asked for 'self-containing' script. ie. one that doesn't
need anything outside but works as is. This example script
you added is useless and can not be used to reproduce anything. Please create a SHORT
(max 5 lines) script that doesn't work.

The parameter passed to the function i prev. post is the stricture returned from
imag_fetchstructure...

I post the function that cause the problem.
Its the for-loop int the wery bottom of the function that cause my problem. If you can
see any wrong logic in the code please let me know :)
I have solved this problem in another way in my current code.
The code below have worked for a long time, but stopped working and caused described
problem after installing - i think php4.0.4 or 4.0.4pl1
Even if i surrond the for-loop with this :
echo "<br>First : $c";
if ($c!=0) {
echo "<br>Second : $c";
for (..) {
echo "<br>Inside for-loop...";
...
}
}
the first echo output 0 but the second echo output another value like 1 or 2.
The strange thing is that if the FIRST echo output 0 the SECOND echo doesnt execute
**BUT** the for-loop execute!
