从字符串中删除数字格式

Question

The following code will turn 1000 into 1,000:

$price = '1000';
$price2 = number_format($price);
echo $price2;

How would I turn 1,000 into 1000? I'm guessing it would be something along the lines of this:

$price = '1,000';
$price2 = remove_format($price);
echo $price2;

It's something that is very simple, but I'll make it into a function for you.

You can do this by just using something like the str_replace() function to remove the , this is what I came up with:

Code:

function remove_format($text){
    $text = str_replace(",", "", $text)
    return $text;
}
