FIXED

Hi I have my own dev server which is running php 5.4.7

PHP 5.4.7 (cli) (built: Oct 2 2012 12:10:57)
Copyright © 1997-2012 The PHP Group

The problem is ?: is giving me a weird http error once in a while (more often than you think)
http://dev.coding-tech.com/test.php
http://dev.coding-tech.com/test2.php

test.php

<?php

$test = "xxx";

echo ($test ?: "no value");

$x = null;
echo "<br />" . ($x ?: "no value");

test2.php

<?php

$test = "xxx";

echo ($test ? $test : "no value");

$x = null;
echo "<br />" . ($x ? $x : "no value");

That's because the variable on the right hand side of ? requires a variable with a value, even if the value is null.

I found this in the PHP manual:

Ternary

Hope this helps

Huh no ?: should work from version 5.3

in test1.php
I should get xxx
no value

Where do you see anywhere that this

echo ($test ?: "no value");

should work?

EDIT: Oh wait, I found it!

Since PHP 5.3, it is possible to leave out the middle part of the ternary operator. Expression expr1 ?: expr3 returns expr1 if expr1 evaluates to TRUE, and expr3 otherwise.

That's new to me. Sorry.

Works for me in 5.3.15:

<?php

$test = "xxx";

echo ($test ?: "no value");

$x = null;
echo "<br />" . ($x ?: "no value");

php -f tern.php 
xxx<br />no value

AND it looks like what you get as well?

Lol everywhere. Shortened ternary operator it is called and working from php 5.3
It's in some big frameworks like symfony and zend.

I got it to work, it was a problem with apc and fixed now by updating.

@4 JackOfAllTrades
No problem, thanks for the help anyway

Hehe, I fixed it, it was a server problem. I thought it was maybe something else that's why I posted. I looked at the problem for a day and couldn't find anything that's why I posted.
