Description: For loop always execute
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 : $c";
for (..) {
echo "<br>Inside for-loop...";
...
}
}
the first echo output 0 but the second echo output another value like 1 or 2.
The strange thing is that if the FIRST echo output 0 the SECOND echo doesnt execute
**BUT** the for-loop execute!
// Parse the parts of message and get info on each
function parseparts($ref, $ofs='') {
global $part_no, $msg_part, $imap, $sorted_msgs, $msg_no, $bgcolor, $background,

$part_no++;
$msg_part[$part_no] = $ref;
$msg_part[$part_no]->index = $ofs;
$ac = count($ref->dparameters);

break;

As I can not reproduce this with latest CVS please try
the latest snapshot from http://snaps.php.net/
And if happens with it too, create one
short but self-containing script which can be used
to reproduce this anywhere without modifications
and add it into this bug report.

When i said ONCE - i didnt mean ONCE :)
It ALWAYS happen in the code referred...

Its not easy reproduceable - i have only seen this happens ONCE - in the specified
function. Its NOT a simple for-loop - the for-loop executes INSIDE a recursively
called function.
I've also tried this one :
---
$c = count($myarray);
if ($c>0) {
echo "c is greater than 0<br>";
for (...) {
...code
}
}
---
then IF c is 0 the echo statement doesnt execute BUT the for loop executes...
I cant figure out why...
If some of you want it i can mail you the file so you can see the things in
perspective.

I can't reproduce this (using code below):
<?php
$c=0;
for($i=0; $i<$c; $i++) {
echo "yesn";
}
?>
Could you try this one?
And note: If the variable passed to count() is not an array,
it will return 1.

The code submitted is inside a function that is called recursively and its not exact
copy of the code.
I've also tried to change the for loop to a while loop with the same result.
