打印出每个数组元素

Question

我有一个数组,我使用print_r,这发生了什么:

Array
(
    [141] => 1
    [171] => 3
    [156] => 2
    [241] => 1
    [271] => 1
    [256] => 1
    [341] => 1
    [371] => 1
    [356] => 1
    [441] => 1
    [471] => 1
)

如何打印索引[141]等？

Answer 1

使用foreach循环来获取

foreach($your_array as $key=>$value) {
    echo 'index is '.$key.' and value is '.$value;
}
