Identify the error in this PHP code snippet handling a POST form:

<?php
if ($_POST['email']) {
    echo 'Email: ' . $_POST['email'];
} else {

Step-by-Step Solution

Solution:

Step 1: Analyze use of $_POST['email'] without isset
The code accesses $_POST['email'] directly without checking if it exists, which can cause an undefined index notice if form not submitted.
Step 2: Explain proper check
Use isset($_POST['email']) to verify the key exists before accessing it.
Final Answer:
No check if $_POST['email'] is set before use -> Option B
Quick Check:
Always check isset($_POST['key']) before use [OK]

Quick Trick: Always use isset() before accessing $_POST keys [OK]
