Wordpress Child Theme

functions.php

<?php
add_action( 'wp_enqueue_scripts', 'enqueue_child_theme_styles', PHP_INT_MAX);

function enqueue_child_theme_styles() {
  wp_enqueue_style( 'parent-style', get_template_directory_uri().'/style.css' );
}
?>

Line 2 in the code should NOT include the PHP_INT_MAX value in the priority parameter.
This results in the parent theme style rules taking precedence over the child style rules (defeating the purpose of the child theme) since the parent style file loads AFTER the child style file.
The call should simply be:
add_action( 'wp_enqueue_scripts', 'enqueue_child_theme_styles');
