check if string is true

[be4real]

Hi everybody!

I have a little problem and maybe you can help me.

I have a string like that: $str = '(1 == 1 || 4 > 3) && 5 < 10 )'
and want to find out if it's true or false.
if($str == true) echo'true';
else echo'false';

Any idea or function I could use? :bemused:

You could take a look into using [man]eval/man.
