Status: Bogus
Bug Type: Scripting Engine problem
Operating System: linux
PHP Version: 5.2.3
New Comment:
Other languages? Let's see:
[EMAIL PROTECTED] dmitry]$ cat x.c; gcc x.c; ./a.out
#include<stdio.h>
int a,b,c;
main()
{
c = a=1,b=2;
printf("a=%d b=%d c=%d\n",a,b,c);
}
a=1 b=2 c=1
[EMAIL PROTECTED] dmitry]$ cat x.pl;./x.pl
#!/usr/bin/perl
$c = $a=1, $b=2;
print "a=$a b=$b c=$c\n";
a=1 b=2 c=1
Guess the result of following:
<script>
c = a=1,b=2;
alert('a='+a+' b='+b+' c='+c);
</script>

I find that very confusing and stupid syntax. Just put the stuff inside
the loop like in all other languages. Don't reopen this anymore, this is
no bug.

How about following examples:
while ($a = mysql_fetch_array(),$rec_no++) {
}
$to_pay = ($left<$total)?($left,$stop=1):$total;

Because it doesn't make any sense elsewhere.
(Disclaimer: I can not think of any other places where it would be
useful, your example is not the best one..)

Actually documentation has nothing about comma expression, the only way
to know about it is to view example 4 of 'for' operator. Though, it is
also mentioned but not explained in Operator Precedence part of chapter
15.
Well, this syntax works inside 'for' structure, so it is supported, why
not to allow to use this syntax in other expressions also?

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php
This syntax is simply not supported, and that is expected.
