using foreach loop how can i do this job? anybody can plz help me?

Answer 1

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

will output

1 1

Answer 2

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

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

Answer 3

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

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

Answer 4

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.
