PHP Reference

Quick Reference

The PHP throw keyword is used to throw exceptions to change the program flow if an unexpected situation arises, such as invalid data.

<?php
try {
    throw new Exception('This is an exception');
}
catch(Exception $e) {
    echo $e->getMessage();
}
?>

PHP Notes:

  • When using PHP, single or double quotation marks are acceptable and work identically to one another; choose whichever you prefer, and stay consistent
  • Arrays count starting from zero NOT one; so item 1 is position [0], item 2 is position [1], and item 3 is position [2] … and so on

We’d like to acknowledge that we learned a great deal of our coding from W3Schools and TutorialsPoint, borrowing heavily from their teaching process and excellent code examples. We highly recommend both sites to deepen your experience, and further your coding journey. We’re just hitting the basics here at 1SMARTchicken.
