Hi all, I woul like to ask a question.
Array{
[0]=>Array{
['Child']=>"2",
['Parent']=>"6"
}
[1]=>Array{
['Child']=>"8",
['Parent']=>"7"
}
}
I would like to use in_array to check whether there is a number '7' in the ['Parent'] for all array. Or is anybody have better suggestion for me without travesal all the array to match the number i want.

you will have to loop through all elements.. I don't see an efficiant use of in_array() here.

PHP Code:

for ($i = 0; $i < count($array); $i++)

{

   if ($array[$i]['Parent'] == 7)

   {

       //Do whatever you want here

   }

}

Mnn... Thank you for you tips. But, I found it that I can use array_search to accomplish my task.

no problem.
tho, array_search will return the "Child" element if it had the value 7 before any of the Parents.
