其中数字索引数组和C语言中的数组一样,下标是为0,1,2…
而关联数组下标可能是任意类型,与其它语言中的hash,map等结构相似。
方法1:foreach
复制代码 代码如下:
<?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
复制代码 代码如下:
<?php
$sports = array(
'football' => 'good',
'swimming' => 'very well',
'running' => 'not good');
while (!!$elem = each($sports)) {
echo $elem['key'].": ".$elem['value']."<br />";
}
?>
输出结果:
football: good
swimming: very well
running: not good
方法3:list & each
复制代码 代码如下:
<?php
$sports = array(
'football' => 'good',
'swimming' => 'very well',
'running' => 'not good');
while (!!list($key, $value) = each($sports)) {
echo $key.": ".$value."<br />";
}
?>
输出结果:
football: good
swimming: very well
running: not good
