Quick Reference
The PHP return keyword ends a function and uses the result of an expression as the return value of the function. If return is used outside of a function, it stops PHP code in the file from running.
<?php
function add1($x) {
return $x + 1;
}
echo '2 + 1 equals ' . add1(2);
?>Output
2 + 1 equals 3PHP 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.
