add into a string other string

[dsp77]

Hello, i have this type of link:

http://www.example.com/cat/name-of-article/5054673 and i want to transform it into: 

http://www.example.com/cat/name-of-article/full_screen/5054673

 

i think it can be done with explode or str_replace but i had no luck.

Any advise?

Thank you

it works and is fast to:)

		foreach(array_slice(explode("/", $a['url']), -2, 1) as $link){
		$dlink = 'http://example.com/cat/'.$link.'/full_screen/'.$a['id'];
	}

All you need to do is work out the position of the far right "/" using strrpos, and then insert text between that point using substr:

 

$str = 'http://www.example.com/cat/name-of-article/5054673';

$pos = strrpos(rtrim($str, '/'), '/');
$str = substr($str, 0, $pos) . '/full_screen' . substr($str, $pos);

echo $str;

 

Notice the use of rtrim in-case there's a trailing slash.
