Quick Reference
The PHP prev() function moves the internal pointer to, and outputs, the previous element in the array.
<?php
$my_cars = array('Lamborghini', 'Ferrari', 'Maserati');
echo current($my_cars) . '<br>';
echo next($my_cars) . '<br>';
echo prev($my_cars);
?>
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
Lamborghini
Ferrari
Lamborghini
Syntax
prev(array)
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.
