php如何读一个多维数据动态的、
Array
(
[3] => Array
(
[0] => Array
(
[seconds] => 16930
[no] => 0
[pt] => 3
[k] => 119981343
[size] => 906330
)
)
[2] => Array
(
[0] => Array
(
[seconds] => 16930
[no] => 0
[pt] => 2
[k] => 119980914
[size] => 472101
)
)
[4] => Array
(
[0] => Array
(
[seconds] => 16930
[no] => 0
[pt] => 4
[k] => 119981696
[size] => 1735787
)
)
[99] => Array
(
[0] => Array
(
[seconds] => 16930
[no] => 0
[pt] => 99
[k] => 119981988
[size] => 679868
)
)
)我如何读到其内的值，就是no pt k size
这是一个动态数据，就是说3,2,4,99不是固定的，因此不能用此法：[4][0][no]
应该怎么办啊？
------解决方案--------------------foreach($ar as $r) {
echo $r[0]['k'];
}------解决方案--------------------foreach($ar as $r) {
foreach($r as $row){
echo $row['k'];
}
}
