Hi !

I've got a simple looking problem, do maybe someone will have simple, short
solution for it.
I hava a string whis is an expression e.g.:
'$a + $b / $c - abs($d)'
As you can see there are vars in it.
What I want to do is to get names of all these vars, that is: $a, $b, $c and
$d.
I appreciate any help

Hey RuBenz

This is what came up my mind:

$str = "\$a + \$b / \$c - abs(\$d)";
preg_match_all ( "/(\\$[\w]+)/", $str, $matches);
print_r ( $matches );
