It's simple but REALLY INSECURE
$str = "array('3'=>'www.tension.com','1'=>'www.seomeuo.com','requestedBy'=>'1')";
eval("\$array = $str;");
You never should use this approach, there another ways to do it like: serialize() and unserialize()

serialization is the better choice

Fixed, first $ sign should be escaped with \

Not fixed. Still get: Parse error: syntax error, unexpected $end in /home/user/test.php(5) : eval()'d code on line 1 – hek2mgl 11

Yes, now it's working, after you've added to the
;. Note that the ; is essentialYou can use the eval() function for that:
$str = "array('3'=>'wwm','1'=>'wom')";
eval("\$a=$str;");
var_dump($a);
However using eval() in your code is considered to be risky and you should not use it. Try to use serialize(), unserialize() instead.

First of all. Do not use eval. It is Evil! http://af-design.com/blog/2010/10/20/phps-eval-is-evil/
Secondly. The simple solution would not to be using this string but simply to use "serialize" when you put it in the DB and unserialize when you pull it out. You are storing a very unusual format.
