Can the set_error_handler function in PHP be used to handle errors in included files as well?

Yes, the set_error_handler function in PHP can be used to handle errors in included files as well. To do this, you can set up a custom error handler function that will handle errors in both the main file and any included files. This custom error handler function should be registered using set_error_handler at the beginning of your main file. 

<?php

// Custom error handler function
function customErrorHandler($errno, $errstr, $errfile, $errline) {
    echo "Error: [$errno] $errstr in $errfile on line $errline";
}

// Register custom error handler
set_error_handler("customErrorHandler");

// Include files here
include 'file1.php';
include 'file2.php';

// Rest of your code
?>
