Getting failure when using filemtime() with wp_enqueue_style

by

I am trying to change the stylesheet file version using the filemtime() function with the wp_enqueue_style with the following snippet

function pro_styles()
{
wp_enqueue_style( 'child-style', get_stylesheet_directory_uri() .'/child-style.css', array(), filemtime(get_stylesheet_directory_uri() .'/child-style.css'), 'all' );
}

add_action( 'wp_enqueue_scripts', 'pro_styles' );

but it is throwing a warning

Warning: filemtime(): stat failed for…..

While i am sure that the file exists

It’s because you’re retrieving it via URL, but filemtime() requires a path. Use get_stylesheet_directory() instead. That returns a path:

function pro_styles()
{
wp_enqueue_style( 'child-style', get_stylesheet_directory_uri() .'/child-style.css', array(), filemtime(get_stylesheet_directory() .'/child-style.css'), 'all' );
}

add_action( 'wp_enqueue_scripts', 'pro_styles' );
