Question

Given
http://host/test/google/oop/a/a

I’m trying to retrieve the last two elements seperated by / so I can do
$myvar = “a_a”;. There could be an ending / or not it needs to work both ways.

I have the following working but it’s pretty ugly, how else could I do it?

$href = preg_split("/[\/]+/", "http://host/test/google/oop/a/a");
$myvar = $href[count($href)-3] . "_" . $href[count($href)-2];

Alternatively you could do it this way:

<?php 
$link = 'http://host/test/google/oop/a/a';

$linkParts=explode('/',rtrim($link,'/'));
$count=count($linkParts);

$desired = $linkParts[$count-2].'_'.$linkParts[$count-1];

echo $desired; //a_a
?>
