[SOLVED] Remove everything after the last "/"?

[aximbigfan]

Hi,

 

I need to find a way to remove everything after the last "/" in a string.

 

For example, this:

/this/is/a/string

 

Needs to become this

/this/is/a

 

Thanks!

Chris

if you're doing it for directories, just use

dirname($str);

if you don't want it to apply to \ on windows then use something like

substr($str, 0, strrpos($str, '/'));

Perfect, thanks!

 

And yeah, it is for dirs. It is for renaming the top level dir.

Darn, it's not working.

 

Here's my code. The idea is that I have a path like this,

aaaa/bbb/ccc

 

I want to rename ccc to something else. So I wanted to use the code I requested ot get the path before ccc, so I could append the new name for ccc on to it, and rename it there.

 

SNIP....		
{
		$old_new = substr($dir, 0, strpos($dir, '/'));
		$path_old = $this->opt_regd . $dir;
		$path_new = $this->opt_regd . $old_new . $new;
}
if (!rename($path_old, $path_new))
/SNIP...

 

EDIT: I'm an idiot. I missed that extra "r". I'll blame it on my laptop keyboard. Clearly I typed it, but the keyboard dropped it.

 

Thanks!

 

Thanks,

Chris

glad you got it working

 

you might consider using dirname though, as it's more portable.
