Are there any best practices or specific permissions that should be set when using mkdir() in PHP scripts?

When using mkdir() in PHP scripts to create directories, it is important to set appropriate permissions to ensure the security and accessibility of the newly created directories. It is recommended to set the permissions to 0755, which allows the owner to read, write, and execute, while others can only read and execute. This ensures that the directory is accessible for necessary operations but restricts write permissions to prevent unauthorized modifications. 

// Create a new directory with appropriate permissions
$directory = 'new_directory';
$permissions = 0755;

if (!file_exists($directory)) {
    mkdir($directory, $permissions, true);
}
