PHP Processing Multiple Arrays Together Changing a multidimensional array to associative array
Example
If you have a multidimensional array like this:
[
['foo', 'bar'],
['fizz', 'buzz'],
]
And you want to change it to an associative array like this:
[
'foo' => 'bar',
'fizz' => 'buzz',
]
You can use this code:
$multidimensionalArray = [
['foo', 'bar'],
['fizz', 'buzz'],
];
$associativeArrayKeys = array_column($multidimensionalArray, 0);
$associativeArrayValues = array_column($multidimensionalArray, 1);
$associativeArray = array_combine($associativeArrayKeys, $associativeArrayValues);
Or, you can skip setting $associativeArrayKeys and $associativeArrayValues and use this simple one liner:
$associativeArray = array_combine(array_column($multidimensionalArray, 0), array_column($multidimensionalArray, 1));
