How can beginners in PHP development effectively learn and understand code snippets they find online?

Issue: Beginners in PHP development may struggle to understand and effectively learn code snippets found online due to lack of experience and knowledge. Solution: To effectively learn and understand code snippets found online, beginners can start by breaking down the code into smaller parts and analyzing each line for its purpose. They can also consult PHP documentation or tutorials to understand any unfamiliar functions or syntax used in the code snippet. Additionally, practicing by implementing the code snippet in a test environment and experimenting with different inputs can help solidify their understanding. Example PHP code snippet: 

<?php
// Code snippet to calculate the sum of an array
$numbers = [1, 2, 3, 4, 5];
$sum = 0;

foreach ($numbers as $number) {
    $sum += $number;
}

echo "The sum of the array is: " . $sum;
?>
