本文介绍PHP中遍历数组的foreach、list、each三个函数的使用方法：
方法1：foreach
<?php
$sports = array(
football => good,
swimming => very well,
running => not good);
foreach ($sports as $key => $value) {
echo $key.": ".$value."<br />";
?>输出结果：
football: good
swimming: very well
running: not good方法2：each
<?php
$sports = array(
football => good,
swimming => very well,
running => not good);
while ($elem = each($sports)) {
echo $elem[key].": ".$elem[value]."<br />";
?>方法3：list & each
<?php
$sports = array(
football => good,
swimming => very well,
running => not good);
while (list($key, $value) = each($sports)) {
echo $key.": ".$value."<br />";
