Get last part of string?

[OhTheNoes]

Hi, I have a variable that is either formatted as:

 

http://thedomain.com/id/xxxx/ or

http://thedomain.com/profiles/dzdf/

 

The URL differs each time but is it possible to make a bit of code that extracts the string between the last two forward slashes? That is, if the variable is the first example, it will out put "xxxx" or if the variable is the second one, it will output "dzdf" but the output is not limited to these two. Sorry if I'm being a bit confusing.

 

Any assistance is much appreciated

You can use preg_match to accomplish this

 

$pattern = '~^http://[\w\d]+\.[com|net|org|gov]/[\w\d]+/([\w\d])+/$~i'; //can add more extensions
$subject = "http://thedomain.com/id/xxxx/";
preg_match($pattern,$subject,$matches);
print $matches[0]; //first match

$pattern = '~^http://[\w\d]+\.[com|net|org|gov]/[\w\d]+/([\w\d])+/$~i'; //can add more extensions
$subject = "http://thedomain.com/id/xxxx/";
preg_match($pattern,$subject,$matches);
print $matches[0]; //first match

 

Sorry, I'm not very good at PHP, please bear with me...

 

I tried doing this

 

$pattern = '~^http://[\w\d]+\.[com|net|org|gov]/[\w\d]+/([\w\d])+/$~i'; //can add more extensions
$subject = $urlInput
preg_match($pattern,$subject,$matches);
$urlResult = $matches[0]; //first match
(bit of html code here so the php breaks into two)
echo $urlResult

 

 

but it's coming out as blank?

If you are simplying parsing a url, use the parse_url function.

 

$path = parse_url($url, PHP_URL_PATH);
echo $path;

 

And a correction to AyKay's code, the $matches[0] does not return the first match, it returns the fully matched string. $matches[1] returns the first match as identified by the parenthesis.

Hello premiso,

 

The code you gave me results in either

/id/xxxx/ or

/profiles/zzzz/

 

but I would like it to only output

xxxx or

zzzz

 

 

Would that be possible?

[premiso]

Yes, with using explode and end

 

$path = trim($path, '/'); // remove any trailing slashes
$path = explode('/', $path);
$last = end($path);
echo $last;

 

Should do it.

Works perfectly. Thank you so much!

echo basename('http://thedomain.com/id/xxxx/');

 

You can use parse_url() first if you are unsure of the format and there might be a filename present.
