How can I sort an array like this so that it would be ASC ordered
by the [1] key in subarrays? I need to maintain only the subarray
key - value pairs. (Do I make sense?)
Array
(
[0] => Array
(
[0] => Logo
[1] => NameC
[2] => Home
[3] => url
)
[1] => Array
(
[0] => Logo
[1] => NameA
[2] => Home
[3] => url
)
[2] => Array
(
[0] => Logo
[1] => NameG
[2] => Home
[3] => url
)
}
http://www.php.net/usort
I think usort would be a bit overkill, he would probably find himself
making a function to sort and maintain the association between the
subarrays. Go with array_multisort, it would be a one-liner.
What total tosh! array_multisort() won't handle this one -- usort() is
correct. The only function needed is a (one-liner!) custom comparison to
compare individual [1] elements -- usort() takes care of all the rest:
function compare_1($a, $b) { return strcmp($a[1], $b[1]); }
usort($array, 'compare_1');
Or even, for single use, collapse it to:
usort($array, create_function('$a,$b', 'return strcmp($a[1], $b[1]);');
Cheers!
