Remove Characters After Nth Occurence Of Symbol

[matthewtbaker]

Good day!

 

I've tried a few routes but haven't managed a simple approach. Ideally I'd like to use one of PHPs built in functions to make the code cleaner and easier to follow.

 

Basically I need to remove anything after a defined number of occurrences of a character from the example string below;

 

 

$iLevels = 2;

$sUrl = http://www.example.com/products/entertainment/films/dvd/page.html

 

So in this case I need to remove anything after the second to last forward slash, deleting dvd/page.html. The number of forward slashes to remove is variable therefore a flexible solution is needed.

 

Thanks for your help/advice in advance!

Try this:

 

 

$url = 'http://www.example.com/products/entertainment/films/dvd/page.html';

echo implode('/', array_slice(explode('/', $url), 0, -2)) . '/';

Aside: array_slice(explode('/', $url), 0, -2) could be replaced with explode('/', $url, -2).

Thanks Silkfire worked like a charm. I will try your shorter approach salathe, thank you.
