Like any other language, loops in PHP are used to execute a statement or block of statements multiple times until and unless a specific condition is met. This helps users save time and effort writing the same code multiple times.

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"; 
    } 
  
?>

Output:

10 
20 
30 
40 
50 
60 
Ram 
Laxman 
Sita
