Combine relative url path

Anon

How I can combine 2 url path (base+relative) in PHP?
For example:

Base: http://www.some.com/one/two
Relative: ../tree/four/doc.htm

Result (my question): http://www.some.com/one/tree/four/doc.htm

Thanks

Read the PHP manual.

Use concatenation by putting a "." between your strings like this:
$base="foo";
$relative="bar";
$total=$base.$relative;

Thanks Vincent, but read my message.

If
Base: http://www.some.com/one/two
Relative: ../tree/four/doc.htm

$total=$base.$relative

then $total=http://www.some.com/one/two../tree/four/doc.htm

not http://www.some.com/one/tree/four/doc.htm

://www.some.com/one/two
Relative: ../tree/four/doc.htm

Oopsie....

well try this:

Base: http://www.some.com/one/two
Relative: ../tree/four/doc.htm

$total=$base.substr($relative,3)

Thanks Vincent, but it is not my question.

I'm sorry for my bad English 😉

I would like combine 2 path, don't concatenation 2 strings.

For example:

Base: http://www.some.com/one/two
Relative: ../../four/doc.htm

now, the new path is http://www.some.com/four/doc.htm

If
Base: http://www.some.com/one/two
Relative: /four/doc.htm
then
result is http://www.some.com/four/doc.htm

Thanks

Okie, no problem

This will take some work.

You could use the explode() function to split the base path into an array.
Then you could do the same with the relative path.
Now you have two arrays that contain the subdirectory names of
the base and relative path.

Now you can check to see if the first element of the relative_array
contains ".."
if it does, that means you have to move one directory backwards in the base path, so you remove the last element from the base_array.
Then you can chck the second element in the relative array, etc.
