How important is hands-on practice or "learning by doing" when learning PHP?

Hands-on practice or "learning by doing" is crucial when learning PHP as it allows for a deeper understanding of the language and its functionalities. By actively coding and experimenting with PHP scripts, learners can better grasp concepts such as syntax, variables, functions, and loops. Additionally, hands-on practice helps in troubleshooting errors and debugging code effectively.

<?php

// Example of hands-on practice with PHP
$number1 = 10;
$number2 = 5;

$sum = $number1 + $number2;
echo "The sum of $number1 and $number2 is: $sum";

?>
