The is_file Function

The is_file function checks whether a file exists at the specified path and whether it is a regular file (not a directory or symbolic link). The function returns true if the file exists and is a regular file, and false otherwise.

Syntax

is_file(string $filename): bool

Example

Let's check the existence of the file 'test.txt':

<?php
	$res = is_file('test.txt');
	var_dump($res);
?>

Code execution result (if the file exists):

true

Example

Let's check the existence of a directory (the function will return false):

<?php
	$res = is_file('directory_name');
	var_dump($res);
?>

Code execution result:

false

Example

Let's check several paths at once:

<?php
	$files = ['file1.txt', 'file2.txt', 'folder'];
	
	foreach ($files as $file) {
		echo "$file: " . (is_file($file) ? 'true' : 'false') . "\n";
	}
?>

Code execution result:

file1.txt: true
file2.txt: false
folder: false
