Description:
------------
output from var_export($var,true) has trailing comma so you have to strip that manually before utilising the returned string.

the manual example shows this behaviour so perhaps its a feature ?

Reproduce code:
---------------
$yaks = array( 'dfdf'=>'a' , 'b' , 'c' , 'd' ) ;
echo '$llama = ' . var_export( $yaks , true ) . ' ;' ;

Expected result:
----------------
$llama = array ( 'dfdf' => 'a', 0 => 'b', 1 => 'c', 2 => 'd' ) ;

Actual result:
--------------
$llama = array ( 'dfdf' => 'a', 0 => 'b', 1 => 'c', 2 => 'd', ) ;

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

The trailing comma while unusual is perfectly valid and the code evaluates correctly.

But why is the comma there? I don't want there because it looks like something's wrong (even if it's correct behaviour)

by the way: you have to check your emailvalidator ... it says my emailaddress is not valid (so now i used another one)

Check documentation. Trailing comma is allowed in PHP.
Comma is there for simplicity. Try to write your own, then you'll see.

It's easy to write code, easy to add additional element.

I have no idea what you're referring.
Create new report if it's new, or add comment to appropriate report.
