How to echo regex

[jagoan-neon]

I want to extract a number + last 2 digit

 

for example 23.72233113213

The result is 23.72

 

$order = 10000;

$rp = 9500;

$pay_pal = $order / $rp;

$pay_pal = $pay_pal + ($pay_pal * 0.034) + 0.3;

$pay_pal = preg_match("/[0-9]+\.[0-9]{2}/",$pay_pal);

 

How to display $pay_pal ? Try to echo it but doesn't works.

 

Thank you.

You can't display it because it returns false ^^

it return 1 or true;

solved (?<=[0-9]+\.[0-9]{2})[0-9]+$
