Question

I would like to search key in multidimensional array and i would like to get corrosponding value associated with that key.
For e.g.
I would like to extract following texts from below array :

SENT AT 12.08ms

And the text

sample id 41962

following is an array print_r() output :

 Array

      [0] => Array

                     [VERSION] => Array

                                 )

                         )

                 )
 )           

Can somebody provide me optimized code for above problem. The multidimensional array contains more than 5000 to 10000 arrays.

Answer 1

If all the array keys have the same structure the following code should work:

foreach($array as $item){
    $sentat = $item['STATUS'][0]['value'][0][0];
    $sample = $item['SAMPLE'][0]['value'][0][0];
}

More detailed information would help us to provide you more tips 🙂
