Quick Reference
The PHP or keyword is a logical operator. The return value will be true if any one of the statements returns true, otherwise it will return false.
The difference between or and || is that or has very low precedence, meaning that most other operations get evaluated first.
<?php
if (15 > 10 or 15 < 20) {
echo 'true';
}
else {
echo 'false';
}
?>Output
truePHP 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.
