How to convert char numbers to int numbers

Hello,

Is there anyway I can convert character numbers (matched by a preg_match and stored into a string) into integer numbers so that I can compare them (==, >, <,...) with other integer variables?

 

$chars = $result_of_preg_match; //EX string = 45309238

$ints = (int)$chars; //OUTPUT = int 45309238

PHP:

 

Thanks! Thats help me too

 

Or:

$chars = $result_of_preg_match; //EX string = 45309238
$ints = $chars+0; //OUTPUT = int 45309238

PHP:

 

In one line this should work (if you do not need the $chars)

$ints = intval($result_of_preg_match);

Code (markup):

intval() can also convert from other 'base' for example Hexadecimal.
