variable if statement

[Anon]

i want to do something like this:

$string="($a==1) OR ($b==2)";

if ($string) { do something ; }

any ideas? i tried using if (eval($string)) but that just gave me errors.

thanks

Try this:

$string = '($a == 1) OR ($b ==2)';

if (eval("return($string);")) { // do something }
