[SOLVED] how to extract numbers out of a string

[ballhogjoni]

I have this string:

 

https://www1.xxxxxxxx.com/partners/links/cardholders/details.asp?idmin=45621&tempid=568261

 

How can I get the numbers 45621 out of the string? Note: the numbers are dynamic so they change all the time.

<?php

 

$url="https://www1.xxxxxxxx.com/partners/links/cardholders/details.asp?idmin=45621&tempid=568261";

 

 

echo $_GET['idmin'];

 

?>

2 ways. Not sure which is faster...

 

<pre><?php

$str = 'https://www1.xxxxxxxx.com/partners/links/cardholders/details.asp?idmin=45621&tempid=568261';

parse_str( parse_url($str, PHP_URL_QUERY), $queryArray );

echo $queryArray['idmin'];

?></pre>

 

or

 

<pre><?php

$str = 'https://www1.xxxxxxxx.com/partners/links/cardholders/details.asp?idmin=45621&tempid=568261';
$expr = '%idmin=(\d++)%';

preg_match( $expr, $str, $match );

echo $match[1];

?></pre>

$a=substr($url,70,-14);

echo $a;
