foreach loop:This loop is used to traverse the array. For each counter in the loop, an array element is allocated and the next counter is moved to the next element. (Recommended: PHP Tutorial)
Syntax:
foreach (array_element as value) { //待执行的代码 }
Usage example:
<?php $arr = array (10, 20, 30, 40, 50, 60); foreach ($arr as $val) { echo "$val \n"; } $arr = array ("Ram", "Laxman", "Sita"); foreach ($arr as $val) { echo "$val \n"; } ?>
