Extract floating point numbers from a string in PHP

Question

I would like to convert a string into floating numbers. For example

152.15 x 12.34 x 11mm

into

152.15, 12.34 and 11
         


        

Answer 1

$str = "152.15 x 12.34 x 11mm";
$str = str_replace("mm", "", $str);
$str = explode("x", $str);
print_r($str); // Array ( [0] => 152.15 [1] => 12.34 [2] => 11 ) 

Tested it and it works on all strings above.
