在使用FirePHP查看我正在使用的内容时检索到的多维(?)数组中是否存在问题:
array(
['day'] => 'Wed'
['is_used'] => 1
[0] =>
array(
['day'] =>
'Wed'
['title'] =>
'onsdag denna veckan 2'
['content'] =>
['price'] =>
)
[1] =>
array(
['day'] =>
'Wed'
['title'] =>
'onsdagslunchen'
['content'] =>
['price'] =>
123123
)
)
如果有任何意义,我想在数组中使用0,1数组......?或者这个阵列坏了吗?
当我尝试
时foreach ($foo as $bar){
echo $bar
}
我得到4个结果,day,is_used和0,1个数组。
答案 0 :(得分:2)
代码正确返回值。它返回$foo
数组的第一个子节点,它们是:
day
is_used
0
1
day
和is_used
是字符串,但由于0
和1
是数组,因此您需要再次遍历它们以获取其值:
foreach ($foo as $fooKey=>$bar){
if(is_array($bar))
// cycle through the array
foreach ($bar as $key=>$value)
// Echo out the string of the array
echo "$fooKey $key = $value<br />";
}
} else {
// Echo out the string
echo "$fooKey = $bar<br />";
}
}
这应该反映出以下内容:
day = Wed
is_used = 1
0 day = Wed
0 title = onsdag denna veckan 2
0 content =
0 price =
1 day = Wed
1 title = onsdagslunchen
1 content =
1 price = 123123

也许这就是你想要的:
foreach ($my_array as $key=>$val) {
if (is_numeric($key) {
// do something with $val (where $val is an array in the example)
}
}
