Try this :

foreach ($array as $value){
   if(array_key_exists('installed',$value)){
      echo $value['installed']. "<br />";
   }
}

If you are not checking for array_key_exists it will show error in first loop.

Absolutely the same way like when you iterate 1 dimensional array:

foreach ($array as $value) {
    var_dump($value);
    var_dump($value['installed'];
}

@Debendra Samal: do you have something more objective than your thoughts? And how is it different from the checked answer?

Debendra Samal Over a year ago

actually I want to checked in this array whether the array contain installed key or not? If installed key is there, I ll do some operation and if not then also I have some operation.

@Debendra Samal: "actually I want to checked in this array whether the array contain installed key or not?" --- we cannot read your mind. If you wanted that - you had to impress that by words in the original question

Loop through the array and get the 'installed' key's value:

foreach ($array as $innerArray) {
    echo $innerArray['installed'];
}
