Question

I have an array in PHP with URLs like below:

http://example.com/apps/1235554/
http://example.com/apps/apple/
http://example.com/apps/126734
http://example.com/images/a.jpg
http://example.com/images/b.jpg
http://example.com/apps/2331234/
http://example.com/apps/orange/

How can I separate out these urls and push them to another array using Regex:

http://example.com/apps/1235554/
http://example.com/apps/126734
http://example.com/apps/2331234/

Only url with apps/{number}/ and apps/{number} should be selected.

Answer 1

foreach ($urls as $url)
{
    if (preg_match('~apps/[0-9]~', $url)) echo $url;
}

or more restrictive:

~apps/[0-9]+(/|$)~

to match either slash or the end of the string.
