PHP结合了两个多维数组并使用一个数组作为键

Question

I would like to combine two multidimensional arrays in a way that in the resulting array, array1 values serve as keys for array2.

These are two example arrays:

$array1 = array(
   array('data1'),
   array('data2'),
   array('data3')
);

$array2 = array(
   array('5','12','4'),
   array('8','2','17'),
   array('20','15','3')
);

The resulting array should look like this:

$array = array(
   'data1' => array('5','12','4'),
   'data2' => array('8','2','17'),
   'data3' => array('20','15','3')
);

How could I achieve this? Thanks!

Answer 1

You can do something like this

$array = [];
$count = count($array1);
for($index = 0; $index < $count; $index++)
{
   $array[$array1[$index][0]] = $array2[$index];
}

This should do what you are trying to achieve
