Error Handling in PHP

 Error Handling in PHP

PHP provides built-in functions to handle errors and exceptions. These functions can be used to catch and handle errors, and to log error messages.

Example:

php

// set error handler function

function custom_error_handler($errno, $errstr, $errfile, $errline) {

    echo "<b>Error:</b> [$errno] $errstr<br>";

    echo "Error on line $errline in $errfile<br>";

    error_log("Error: [$errno] $errstr on line $errline in $errfile", 1, "admin@example.com");

}

set_error_handler("custom_error_handler");

// trigger an error

echo $test;
