The mkdir Function
The mkdir function creates a new directory at the specified path.
The first parameter of the function accepts a string with the path to the directory, the second (optional) - access permissions
as an octal number, the third (optional) - a flag for recursive directory creation.
By default, permissions are set to 0777 (maximum permissions).
Syntax
mkdir(path, [mode], [recursive], [context]);
Example
Let's create a directory 'test' in the current folder:
<?php
mkdir('test');
?>
Example
Let's create a directory specifying 0755 access permissions:
<?php
mkdir('test2', 0755);
?>
Example
Let's create nested directories using the recursive flag:
<?php
mkdir('test3/sub1/sub2', 0777, true);
?>
Example
Let's check if the directory exists before creating it:
<?php
$dir = 'new_dir';
if (!file_exists($dir)) {
mkdir($dir);
echo 'directory created';
} else {
echo 'directory already exists';
}
?>
