php检查数组键是否设置且不等于

Question

How can I do simple check in the following scenario. This is my array:

[data] => Array ( [0] => blog ... )

This does not seem to be working:

if(isset($data[1]) != "page") { 
   do stuff here...
}

I need to check if key [1] is set and value not equal to "page"

Answer 1

I found a better solution:

if(!array_search("page", $data)) {
   // do stuff here
}

This works for me
