How to create an associative array using a 2 dimentional array in php?

Question

How can i create an associative array using the array below, In the fastest and shortest way.

$list = array(array('name', 'aram'), array('family', 'alipoor'));

Something like:

$list = array('name' => 'aram', 'family' => 'alipoor');

Answer 1

$assocArray = array();

foreach($list as $subArray)
{
    $assocArray[$subArray[0]] = $subArray[1];
}

Answer 2

The shortest I can think of:

$newlist = array();
foreach ( $list as $keyval ) {
    $newlist[ $keyval[0] ] = $keyval[1];
}

Answer 3

Terrible approach, but

$lst = array_combine(array_map('array_shift',$list), array_map('array_pop',$list));

Works only for two-element inner arrays.

Note: three implicit loops in this solution. So better use approach from Rijk van Wel or kevinmajor1 answer

Answer 4

I generally think foreach is pretty well readable and normally pretty fast. If you want it in one line, you can do with foreach as well:

$nl = array(); foreach($list as $k=>$v) $nl[$k]=$v; $list = $nl; unset($nl);

Which is basically demonstrating that there is no value in getting something "single line".

Or if you prefer callbacks for some reason I don't know of:

$list = array_reduce($list, function($v,$w) {return $v+array($w[0]=>$w[1]);}, array());

Which demonstrates that as well. It will hardly be faster than foreach, in any case, the speed differences most certainly do not matter in your case.
