How I make/convert a string (eg $x='346765' to $y=346765) to a number in PHP ?

intval() (http://hr.php.net/intval)

[GJay]

$x = '12345';
$y = (int) $x;
$z = intval($x);
settype($x, 'int'); //note this is done to the original variable

(replace 'int' with 'float' if preferred)

A lot of the time you don't need do it explicitly though, PHP will do it for you when it's necessary.
