Differences between “include” and “require” in PHP
Differences between “include” and “require” in PHP, both include and require are php functions to include a file, and they act different depending on the results. If we are using include and is there any error in including file there is no problem with include, it moves to next step by showing an warning. And in require if it’s unable to require a file it will shows an fatal error message and it stops processing of remaining script.
include PHP function
The include statement includes and evaluates the specified file.
We can include php files in two types.
<?php include('file.php'); ?>
<?php include 'file.php'; ?>

require PHP functions
require is identical to include except upon failure it will also produce a fatal E_COMPILE_ERROR level error. In other words, it will halt the script whereas include only emits a warning (E_WARNING) which allows the script to continue.
<?php require('file.php'); ?>
<?php require 'file.php'; ?>
