[php] How do I get a file name from a full path with PHP?

To do this in the fewest lines I would suggest using the built-in DIRECTORY_SEPARATOR constant along with explode(delimiter, string) to separate the path into parts and then simply pluck off the last element in the provided array.

Example:

$path = 'F:\Program Files\SSH Communications Security\SSH SecureShell\Output.map'

//Get filename from path
$pathArr = explode(DIRECTORY_SEPARATOR, $path);
$filename = end($pathArr);

echo $filename;
>> 'Output.map'
