Sort a set of multidimensional arrays by array elements
- by Joseph Carrington
Let's say I've started here:
$arr[0] = array('a' => 'a', 'int' => 10);
$arr[1] = array('a' => 'foo', 'int' => 5);
$arr[1] = array('a' => 'bar', 'int' => 12);
And I want to get here:
$arr[0] = array('a' => 'foo', 'int' => 5);
$arr[1] = array('a' => 'a', 'int' => 10);
$arr[1] = array('a' => 'bar', 'int' => 12);
How can I sort the elements in an array by those elements elements?
Multidimensional arrays always feel like a little bit more than my brain can handle (-_-) (until I figure them out and they seem super easy)
