Slicing a multi-dimensional PHP array across one of its elements

Question

Say for example you just queried a database and you recieved this 2D array.

$results = array(
    array(\'id\' => 1, \'name\' => \'red\'  , \'spin\' =&         


        

Answer 1

I think this will do what you want

array_uintersect_uassoc

You would have to do something like this

$results = array(
    array('id' => 1, 'name' => 'red'  , 'spin' =>  1),
    array('id' => 2, 'name' => 'green', 'spin' => -1),
    array('id' => 3, 'name' => 'blue' , 'spin' => .5)
);
$name = array_uintersect_uassoc( $results, array('name' => 'value')  , 0, "cmpKey");
print_r($name);

//////////////////////////////////////////////////
// FUNCTIONS
//////////////////////////////////////////////////
function cmpKey($key1, $key2) {
  if ($key1 == $key2) {
    return 0;
  } else {
    return -1;
  }
}

However, I don't have access to PHP5 so I haven't tested this.
