stripping part of url

[Anon]

Hi,

How do I strip a part of an url?

If i have an url like: www.mydomain.com/files1/file1.php

or

www.mydomainc.com/files2/file2.htm

how do I end up with:

www.mydomain.com/files1/

and

www.mydomain.com/files2/

??

Thx in advance for helping me out

P.S. it should strip out numberurls as well, like:

www.mydomain.com/files1/2394885=65?3459
to
www.mydomain.com/files1/

If you want to "strip out" always the LAST part (filename), then make an array, and reverse it:
<?PHP
$dir_array = explode("/", $PHP_SELF);
$rev = array_reverse($dir_array);
?>

$rev[0] will always be the file name.

You can then get rid of it and switch it back.

use this function:

$new_str=substr_replace("www.mydomainc.com/files2/file2.htm ","",strrpos("/file2.htm")+1);

bye.

Using the environment variables $HTTP_HOST, $SCRIPT_NAME, $QUERY_STRING, etc and so on, will allow you a little more flexibility than hardcoding the values. http://www.php.net/manual/en/language.variables.predefined.php for more info.

This sounds very usefull...

2 more questions arise:

• to get rid of the $rev[0] and keep the rest, how would I code something like that (never done that b4)

• what happens if the url doesn't contain a file name at the end and I use this code, the $rev[0] would contain something else which I don't want to get rid of, right?

thx a lot so far

Use the unset() function to destroy an entry from an array...

You are correct in your assumptions as to the second question. You could use unset() conditionally based on != \".\"

Ok thx m8, I am gonna give it a try and test is iwth the != condition...

thx a lot!

uhmzzz
the != condition you mentioned...what does it do exactly cause I can't figure it out and it seems to me it should be something like:

if ($rev[0] != like a filename)
{
don't unset
}
else
unset ($rev[0])
}

here "like a filename" so be something else, but the \".\" you told me....is not quite what it should be, is it'? I can't figure out what what it should be.. (man I should have gone to school for this 😉 )

thx loads for your help

The forum added the slashes.

Anyway you should use a regex to test for the presence of a "dot".

Read up on ereg()...

I am not to savvy on these, but you might try:
ereg("^[.]+$", $rev[0]);

...if you get a match on this then you know it is 'anyfilename.anyext'
