Note: The each() function is deprecated as of PHP 7.2. |
This function returns the current element’s key and value in an array as a sub-array with four elements: two for the value (1 and Value), and two for the key (0 and Key).

The same example as above, but using a loop to output the entire array.

A demonstration of all the related methods:
| <?php $people = array(“Peter”, “Joe”, “Glenn”, “Cleveland”); echo current($people) . “<br>”; // The current element is Peter echo next($people) . “<br>”; // The next element of Peter is Joe echo current($people) . “<br>”; // Now the current element is Joe echo prev($people) . “<br>”; // The previous element of Joe is Peter echo end($people) . “<br>”; // The last element is Cleveland echo prev($people) . “<br>”; // The previous element of Cleveland is Glenn echo current($people) . “<br>”; // Now the current element is Glenn echo reset($people) . “<br>”; // Moves the internal pointer to the first element of the array, which is Peter echo next($people) . “<br>”; // The next element of Peter is Joe print_r (each($people)); // Returns the key and value of the current element (now Joe), and moves the internal pointer forward ?> |
