Quick Reference
The PHP in_array() function searches an array for a specific value. If the search parameter is a string and the type parameter is set to TRUE, the search is case-sensitive.
<?php
$my_cars = array('Lamborghini', 'Ferrari', 'Maserati');
if (in_array('Maserati', $my_cars)) {
echo 'Value Found';
}
else {
echo 'Value NOT found';
}
?>
Note
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.
Output
Value Found

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.
