)
[1] => Array
(
[0] => product
)
)
)
并且我有一个变量$ categ.例如$ categ =" homeandgardenairconditioner-Type " 那么我想知道其"名称"为" homeandgardenairconditioner-Type "
and I have a variable $categ.For example $categ = "homeandgardenairconditioner-Type" then I want to know the index of the parent array whose "name" is "homeandgardenairconditioner-Type"
即--- o/p应该为9
i.e --- o/p should be 9
如何获取此索引.请帮助我
how to get this index. Please help me
谢谢
推荐答案
我认为您正在寻找:
function getIndex($name, $array){
foreach($array as $key => $value){
if(is_array($value) && $value['name'] == $name)
return $key;
}
return null;
}
