Getting all text up until last / in str.

[Anon]

Hey guys,

I want to use a PHP script to help determine the <base> for html output.

The variable I want to play with could be:

folder/blah.txt

or

folder/folder2/blah.txt

I want to be able to assign all text up to and including the last /, e.g.:

folder/

or

folder/folder2/

What is the best way to do this? I was thinking read each letter into an array, and check each array element from the end to the start until you find the first /. Then assign array[0] to array[num with /] to a variable.

Seems a looooong way to go about things, there must be a friendly way to use a php function to do this. Anyone have any ideas?

eregi() is fun. search for it in the manual in the left column.

Like Michael said: check the eregi and preg_* functions. But they are something you have to learn how to do.

If you look at the STRINGS functions in the manual you will find a function that lets you search for a character starting at the end of the string working towards the front,
and you'll find a function that lets you grab arbitrary pieces of strings.

Read it and then read it again.
