Read from the right

[Anon]

What is the function to read the characters starting from the right? I don't know where to look in the manual...

For example, I want to grab the last four characters of variable $test

$test = "phpisreallycool";

With the proper function I can 'grab' the characters "cool" only.

Hi David,

The function to grab the characters from the end is the same as to grab the characters from the beginning, except that you use negative values instead.

So, you'd use the following command

substr($test, -4);

to capture the string "cool".

There is a optional third argument to determine the length of the string, for example:

substr($test, 6, 6); should return "really".

Cheers,

David

And that's in the manual under 'string functions'.
Just so you know where to look :-)
