下面介紹PHP中遍歷關聯數組的三種方法：
foreach

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

程序運行結果：
football: good
swimming: very well
running: not good
?
each

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

程序運行結果：
football: good
swimming: very well
running: not good
?
list & each

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

程序運行結果：
football: good
swimming: very well
running: not good
?
