Extract numbers from phone number input field (PHP)

I've got a phone number input field, which allows a user to add a phone number in whatever format they want (555-555-5555, (555) 555 - 5555, etc).

Since it a phone number field only, I can ignore everything but the numbers in the field.

I'm currently using the following code. It extracts all the numbers, but the issue is that they are not in order - it's in a jumbled order.

How do I extract the numbers in the order that they appear in the original string?

preg_match_all('/\d+/', $Phone, $matches);

$Phone = implode('', $matches[0]);

Edit: They are actually not in a jumbled order from this function - I was inserting the numbers into a int(10) database field, which caused the jumbling. But, the answers below are still a more efficient way of accomplishing my goal.

Use preg_replace to remove any non-digits:

$numbers = preg_replace('/[^\d]/','',$Phone);

Note: '[^\d]' can be replaced with '\D' (safe in non-unicode mode).

Try it

if (!preg_match("/^[0-9\-]*$/",$Phone)) {
    echo "Only Numeric and strip (-)";
}

Example:

Good: 0877-9320-9356

Failed: 0877 9320 9356 or 087793209356

Why not just replace everything in the string that is not a digit?

$number = preg_replace("/[^0-9]/", '', $Phone);
