A simple PHP An example of looping a one-dimensional array is to first convert the string into an array according to certain rules, and then traverse the output. It is actually a very simple method, because a two-dimensional array structure diagram I recently made was a headache, so I can't remember how to perform traversal output for a while. The simple example code is as follows:

foreach traverses the array

<?php 
/* 
 * 数组的遍历 
 */ 
  $language = array("French",'German','Russian','Chinese','Hindi','Quechu'); 
  foreach ($language as $key => $value) { 
    echo $key.'='.$value.'<br />'; 
  } 
?>

Traverses the associative array

<?php 
  /* 
   * 关联数组的遍历 
   */ 
   $userList = array('UserName'=>'Lilia','Gender'=>'female','Age'=>'23','School'=>'Peking University'); 
   foreach ($userList as $key => $value)  
  { 
    echo $key.'='.$value.'<br />'; 
   } 
?>
