在PHP中數組分為兩類： 數字索引數組和關聯數組。 
其中數字索引數組和C語言中的數組一樣，下標是為0，1，2… 
而關聯數組下標可能是任意類型，與其它語言中的hash，map等結構相似。 
方法1：foreach 

復制代碼代碼如下:

<?php 
$sports = array( 
'football' => 'good', 
'swimming' => 'very well', 
'running' => 'not good'); 
foreach ($sports as $key => $value) { 
echo $key.": ".$value."<br />"; 
} 
?> 

輸出結果： 
football: good 
swimming: very well 
running: not good 
方法2：each 

復制代碼代碼如下:

<?php 
$sports = array( 
'football' => 'good', 
'swimming' => 'very well', 
'running' => 'not good'); 
while (!!$elem = each($sports)) { 
echo $elem['key'].": ".$elem['value']."<br />"; 
} 
?> 

輸出結果： 
football: good 
swimming: very well 
running: not good 

方法3：list & each 

復制代碼代碼如下:

<?php 
$sports = array( 
'football' => 'good', 
'swimming' => 'very well', 
'running' => 'not good'); 
while (!!list($key, $value) = each($sports)) { 
echo $key.": ".$value."<br />"; 
} 
?> 

輸出結果： 
football: good 
swimming: very well 
running: not good
