getting int value from comma separated number php

Question

How do I turn a thousand-comma separated string representation of an integer into an integer value in PHP? (is there a general way to do it for other separators too?)

e.g. 1,000 -> 1000

Edit (Thanks @ghost) Ideally, decimals should be handled, but I could accept a solution that truncates at a decimal point.

Answer 1

If thats simple as it gets you could use filter_var():

Click to copy

$number = '1,000';
$number = (int) filter_var($number, FILTER_SANITIZE_NUMBER_INT);
var_dump($number);

Or

Click to copy

$number = '1,000.5669';
$number = (float) str_replace(',', '', $number);
var_dump($number);
