Extract 2 sets of numbers from a string using PHP's preg?

Question

Here's some PHP code:

$myText = 'ABC #12345 (2009) XYZ';

$myNum1 = null;

$myNum2 = null;

How do I add the first set of numbers from $myText after the # in to $myNum1 and the second numbers from $myText that are in between the () in to $myNum2. How would I do that?

Answer 1

If you have an input string of form "123#456", you can do

$tempArray = explode("#", $input);
if (sizeof($tempArray) != 2) {
    echo "OH NO! Something bad happened!";
}
$value1 = intval($tempArray[0]);
$value2 = intval($tempArray[1]);
echo "Result: " . ($value1 + $value2);

Answer 2

preg_match('/#(\d+).*\((\d+)\)/', $myText, $matches);
$myNum1 = $matches[1];
$myNum2 = $matches[2];

assuming you have something like:

" stuff ... #123123 stuff (456456)"

that will give you $myNum1 = 123123 $myNum2 = 456456
