其中數(shù)字索引數(shù)組和C語(yǔ)言中的數(shù)組一樣，下標(biāo)是為0，1，2…
而關(guān)聯(lián)數(shù)組下標(biāo)可能是任意類型，與其它語(yǔ)言中的hash，map等結(jié)構(gòu)相似。
方法1：foreach
復(fù)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(jié)果：
football: good
swimming: very well
running: not good
方法2：each
復(fù)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(jié)果：
football: good
swimming: very well
running: not good
方法3：list & each
復(fù)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(jié)果：
football: good
swimming: very well
running: not good
