Updated by: [EMAIL PROTECTED]
Reported By: php at hristov dot com
Status: Open
Bug Type: Scripting Engine problem
Operating System: All
PHP Version: 5.3CVS-2008-05-07 (CVS)
New Comment:
To make it even easier for testing :
./php -r '$a=1; $b = ($a, 2);'
The equivalent in C is:
#include <stdio.h>
int main(void)
{
int a = 1, c;
c = (a, 2);
printf("%d\n", c);
}
"," has lower prio than =, thus the brackets.

Sorry, but your problem does not imply a bug in PHP itself. For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions. Due to the volume
of reports we can not explain in detail here why your report is not
a bug. The support channels will be able to provide an explanation
for you.
Thank you for your interest in PHP.
The ternary operator is not supposed to support that syntax, and it
doesn't.
So this is not a bug, and I'm not sure it's a good feature request
either: ternary syntax is suited for simple cases. But if you really
think it should be implemented, file a feature request.

Description:
------------
In the following case the parser bails out:
php -r 'echo true? $t++,"true":"false";'
with
Parse error: syntax error, unexpected ',' in Command line code on line
1
The following mini-C program however does compile, although gcc is kind
of stupid to realize that there should be no warning:
#include <stdio.h>
int main(void)
{
int t=0, f=0;
printf("%s\n", (1==1) ? t++,"True":"False");
}
[EMAIL PROTECTED]:~/dev> gcc -o a a.c
[EMAIL PROTECTED]:~/dev> ./a
True
The comma does work however when used in a for() loop :
[EMAIL PROTECTED]:~/dev> php -r 'for($i=0; $a++, $i < 2; $i++) echo "-";
echo "\n";'

Reproduce code:
---------------
php -r 'echo true? $t++,"true":"false";'
Expected result:
----------------
true
