Seperate number from end of url

[frobak]

Hi

 

I need to take the number off of the end of a url and do some processing with it.

 

so for example:

 

www.something.com/something/10001

 

i will need to seperate them into 2 different variables, for example:

 

$var1 = www.something.com/something/

$var2 = 10001

 

is this possible?

 

Thanks

Does the number always appear after a slash "/"?

[frobak]

yes

[ialsoagree]

$var2 = substr(strrchr(__FILE__, '/'), 1);
$var1 = substr(__FILE__, 0, -(strlen($var2)));

 

I believe this will work, but it's untested, I'm just trying to work it out in my head so I strongly suggest testing it first and if it's not giving you what you expect, report back on your results.

great thanks, ill test and report back.

hang on, sorry. So how would i input the url to be processed by that code?

 

I assume the url is within the "_FILE_", so how do i get it into that? can i assign like a normal variable?

[ialsoagree]

__FILE__ is a global constant defined by PHP. It should contain the entire URL and, iirc, any get variables (get variables WILL break this code iirc, please let me know if that's a problem).

so i have a form with an input, and a user will enter the full url into this input, and submit the form. How do i catch the user inputted url and get that into _FILE_?

[ialsoagree]

Actually, __FILE__ might not do what I'm thinking.

 

In any event, your 2nd problem is more straight forward. You can simply replace __FILE__ with wherever the user input is stored... IE. if it was submitted in a text box named "url" you'd replace __FILE__ with $_POST['file']

 

But you should make sure to validate user input in advance!

 

$var2 = substr(strrchr($_POST['url'], '/'), 1);
$var1 = substr($_POST['url'], 0, -(strlen($var2)));

ialsoagree, thanks for that. worked like a treat!

You might be able to make a more dynamic solution from this:

function segment($index = 1)
{
$segments = explode ('/', $_SERVER['REQUEST_URI']);

if (!empty($segments)) {
	array_shift($segments);

	return $segments[$index - 1];
}

return null;
}

 

To use, simply count the number of "segments" after your domain and there you go. So in "www.something.com/something/10001", doing echo segment(2) would echo "10001".

 

EDIT: By the way I didn't rigorously test this, just a push in the right direction.

Frobak, your site contact form is flawed. I can post blanks.
