我在下面有一个多维数组,我想循环遍历它并将[menu_cats]的值从一个数字更改为一个字符串,该字符串是从数据库选择中提取的.这可能吗？数组的名称是’result’.
Array
(
[0] => Array
(
[0] => Array
(
[menu_cats] => 1
[item] => Introduction
[link] => needs
)
[1] => Array
(
[menu_cats] => 1
[item] => Needs Assessment
[link] => needs/needs.PHP
)
)
[1] => Array
(
[0] => Array
(
[menu_cats] => 2
[item] => Introduction
[link] => knowledge
)
[1] => Array
(
[menu_cats] => 2
[item] => Administer Knowledge Pre-Test
[link] => knowledge/pre_test.PHP
)
)
)
foreach($result as $key => $subarray) {
foreach($subarray as $subkey => $subsubarray) {
$result[$key][$subkey]['menu_cats'] = 'your string here';
}
}
