In this article, We’ll see how to get file extension in php.

We’ll use pathinfo() function to get the file extension.

pathinfo() function returns information about a file path: either an associative array or a string, depending on options.

Below an example:

 $filename = "report.xls";
 $ext = pathinfo($filename, PATHINFO_EXTENSION);
 echo $ext; // Output xls
