How do i go about removing 51365 from a string?

Just wondering if you can help me out with something. I have a string with a seri开发者_如何学编程es of numbers like 58498, 53980, 84578. Always 5 numbers in the series. Whats the best way to go about removing these?

You could do it with a regex.

$new_string = preg_replace("/\d{5},?/",'',$string);

preg_replace (php doc).

You can find the 5-number strings using the pattern: /\d{5}/g and remove each occurrence.

Use it like this:

$string = preg_replace("/\d{5}/g", "", $string); (the g is for global (all occurrences))

If you want to get them (not remove them) then you should use:

preg_match (php doc)

Use it like this:

$matches = array();
preg_replace("/\d{5}/g", $matches);
foreach($matches as $match) {
    // do something with each $match
}
