Quick Answer

Implement proper error management.

Understanding the Issue

PHP provides multiple error handling approaches including exceptions, error reporting levels, and custom handlers.

The Problem

This code demonstrates the issue:

Php Error 
<?php
// Undefined variable causes notice
echo $undefined;

The Solution

Here's the corrected code:

Php Fixed 
<?php
// Solution 1: Set error reporting
error_reporting(E_ALL);
ini_set("display_errors", 1);

// Solution 2: Try-catch blocks
try {
    riskyOperation();
} catch (Exception $e) {
    error_log($e->getMessage());
    http_response_code(500);
}

// Solution 3: Custom error handler
set_error_handler(function($severity, $message, $file, $line) {
    throw new ErrorException($message, 0, $severity, $file, $line);
});
