How to Use PHP pathinfo() Function to Get File Path Components (original) (raw)

Summary: in this tutorial, you will learn how to use the PHP pathinfo() function to get the information on a file path.

Introduction to the PHP pathinfo() function #

The PHP pathinfo() function accepts a file path and returns its components:

pathinfo ( string <math xmlns="http://www.w3.org/1998/Math/MathML"><semantics><mrow><mi>p</mi><mi>a</mi><mi>t</mi><mi>h</mi><mo separator="true">,</mo><mi>i</mi><mi>n</mi><mi>t</mi></mrow><annotation encoding="application/x-tex">path , int </annotation></semantics></math>path,intflags = PATHINFO_ALL ) : array|stringCode language: PHP (php)

The pathinfo() function has two parameters:

$path is the file path from which you want to get the information.
$flags parameter specifies the part element to return.

The following table shows the valid flag values:

Flag	Meaning
PATHINFO_DIRNAME	Return the directory name
PATHINFO_BASENAME	Return the base name
PATHINFO_EXTENSION	Return the file extension
PATHINFO_FILENAME	Return the file name (without the extension)

If you don’t pass the $flag argument, the pathinfo() function will return all components of a file path.
