What are the potential pitfalls of relying solely on online resources for PHP development?

Relying solely on online resources for PHP development can lead to outdated or incorrect information, as well as a lack of understanding of the underlying principles. To mitigate this risk, it's important to consult official documentation, reputable sources, and actively engage in learning and practicing PHP programming. 

<?php
// Example of using official PHP documentation for array functions
$fruits = array("apple", "banana", "orange");
$last_fruit = end($fruits);
