php - substring from end of text

Question

I am looking to get the substring from the end of a line of text, say

$text = "bob/hello/myfile.zip";

I want to be able to obtain the file name, which i guess would involve getting everything after the last slash as a substring, can anyone help me how to do this is PHP? A simple function like

$fileName = getFileName($text);

Answer 1

Check out basename().

Answer 2

I suppose you could use strrpos to find the last '/', then just get that substring:

$fileName = substr( $text, strrpos( $text, '/' )+1 );

Though you'd probably actually want to check to make sure that there's a "/" in there at all, first.

Answer 3

$text = "bob/hello/myfile.zip";
$file_name = end(explode("/", $text));
echo $file_name; // myfile.zip

end() returns the last element of a given array.

Answer 4

As Daniel posted, for this application you want to use basename(). For more general needs, strrchr() does exactly what the title of this post asks.
