What about this :
那这个呢 ：
foreach ($info as $name => $locations) {
foreach ($locations as $location) {
echo "Area {$name} and person located {$location}<br />";
}
}
Which means :
意思是 ：
- One loop for the first dimension of the array,
- and, then, one loop for the second dimension -- iterating over the data gotten from the first one.
- 数组的第一维的一个循环，
- 然后，第二个维度的一个循环——迭代从第一个维度获得的数据。

And for printing array with one more index name:
并打印一个多一个索引名称的数组：
$info = array (
"00500" => array( "0101" => "603", "0102" => "3103", "0103" => "2022"),
"01300" => array( "0102" => "589", "0103" => "55"),
"02900" => array( "0101" => "700", "0102" => "3692", "0103" => "2077")
);
You can do this:
你可以这样做：
foreach ($info as $key => $values) {
foreach ($values as $anotherkey => $val) {
echo 'key:'.$key. ' AnotherKey: '.$anotherkey.' value:'.$val.'<br>';
}
}
output will be:
输出将是：
key:00500 AnotherKey: 0101 value:603
key:00500 AnotherKey: 0102 value:3103
key:00500 AnotherKey: 0103 value:2022
key:01300 AnotherKey: 0102 value:589
key:01300 AnotherKey: 0103 value:55
key:02900 AnotherKey: 0101 value:700
key:02900 AnotherKey: 0102 value:3692
key:02900 AnotherKey: 0103 value:2077
