PHP Regular Expression - Get number from string

I have a string sequence that goes like this: <x:object*10/>. I want to replace that tag with something else that depends on what number it is. I match the tag above with /<x:object\*[0-9]+\/>/ and using preg_replace i can r开发者_运维技巧eplace it all with the content I want. I just need that number now.

How can I get the number please?

By capturing it:

/<x:object\*(?P<my_number>[0-9]+)\/>/

It will be captured with name "my_number"...

Full code would be sth like this:

<?php
preg_match_all(`/<x:object\*(?P<my_number>[0-9]+)\/>/`, $where_to_search, $matches);
var_dump($matches); // Dump the matches to see in detail.
?>

Try this one :)

/<x:object\*([0-9]+)\/>/

better use

/<x:object\*([0-9]+)\/>/
