In Php, how to get float value from a mixed string?

Question

I got a string like:

$str = \"CASH55.35inMyPocket\";

I want to get 55.35 only.

I tried:

$str = flo

You can try a little Function to extract that value for you before using either floatval or (float).

Something like:

function myFloats($str) {

  if(preg_match("#([0-9\.]+)#", $str, $match)) { // search for number that may contain '.'
    return floatval($match[0]);
  } else {
    return floatval($str); // take some last chances with floatval
  }
}

then test:

echo myFloats("CASH55.35inMyPocket");
