Question

I’m trying to isolate the percentage value in a string of text. This should be pretty easy using preg_match, but because the percentage sign is used as an operator in preg_match I can’t find any sample code by searching.

$string = 'I want to get the 10%  out of this string';

What I want to end up with is:

$percentage = '10%';

My guess is that I’ll need something like:

$percentage_match = preg_match("/[0-99]%/", $string);

I’m sure there is a very quick answer to this, but the solution is evading me!

Answer 1

if (preg_match("/[0-9]+%/", $string, $matches)) {
    $percentage = $matches[0];
    echo $percentage;
}
