PHP中遍历关联数组的方法

下面介绍PHP中遍历关联数组的三种方法：
foreach

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

程序运行结果：
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']."
";
}
?>

程序运行结果：
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."
";
}
?>

程序运行结果：
football: good
swimming: very well
running: not good
