Question

I want to select the array in which the element exist

Array ( 

  [0] => Array ( [0] => woman [synonym] => lady [1] => girl [word] => girl )

  [1] => Array ( [0] => man [synonym] => man [1] => boy [word] => boy )

) 

If I use

array_search('girl', $array);

It will just return the key, but I want to select the num of the array and later on, to get that data

Answer 1

I suppose you are looking for array_filter():

function filter($array) {
    return in_array('girl', $innerArray);
}
$filter = array_filter($yourArray, 'filter');

The same concept using PHP-5.4 callbacks in a single line:

array_filter($array, function($innerArray) {return in_array('girl', $innerArray)});
