how to get the key of an item of the array inside foreach loop in php

Question

Below is the example of the array that I have.

  Array (
[952] => Array ( [Date] => 2016-06-23 01:55:17 [SValues] => Array ( [total] => 1 [Name] => Name [OverAge] => No))
[91] => Array ( [Date] => 2016-06-23 01:55:17 [SValues] => Array ( [total] => 1  [Name] => Name [OverAge] => No))
[83] => Array ( [Date] => 2016-06-23 01:55:17 [SValues] => Array ( [total] => 1 [Name] => Name [OverAge] => No)))

And then, I put this array inside the foreach loop.

foreach($the-main-array as $item)
{
          //I want to get the key of the item here (952,91,83)
}

So how can I get the key of the item inside the loop?

Please help me. Thanks in advance.

You just need to specify a variable to store the key in as part of your foreach loop setup. You can do that like this:

foreach($the-main-array as $key => $item){
    echo "This is the key: ".$key;
}

For clarity, you can call the $key variable anything you like. It doesn't have to be $key.

Use This,

{
// Put your code here.
// $key have the key value.

}

foreach($mainArray as $k => $item){
    $k is the key
    $item is the value
}
