case insensitive array sort?

[eternalprophet]

How can I sort an array, so that instead of

aaron
james
mike
Brian
Dan

I would get

aaron
Brian
Dan
james
mike

I tried sort($arrayname) but that doesn't work. I also tried natsort($arrayname) but that didn't work either.

Exact code is simple:

$names[0]=aaron;
$names[1]=mike;
$names[2]=Brian;
$names[3]=james;
$names[4]=Dan;

sort($names);
for ($x=0;$x<sizeof($names);$x++){
echo $names[$x];
}

suggestions?

someone said add reset($names) after the sort, I tried that but no luck.

Have you tried:

sort($array, SORT_STRING);

PHP Manual: [man]array[/man]

Thanks for the suggestion, but I tried that 🙂

I tried sort($names, SORT_STRING) as well as SORT_REGULAR, I tried ksort, usort, asort, natsort, every sort I could possibly think of.

Any other suggestions?

btw, SORT_STRING gave me the words starting with capital letters in alphabetical order then the words with lowercase letters in alphabetical order.
😕 frustated i am

Ok, then you need [man]usort()[/man]. Something like this:

function cmp ($a, $b) {
    $a=strtolower($a);
    $b=strtolower($b);
    if ($a == $b) return 0;
    return ($a < $b) ? -1 : 1;
}

$a = array ('z','b','E','Q','A');
print_r($a);
echo '<br />';
usort ($a, "cmp");
print_r($a);

[eternalprophet]

function cmp ($names, $b) {
$names=strtolower($names);
$b=strtolower($b);
if ($names == $b) return 0;
return ($names < $b) ? -1 : 1;
}

usort ($names, "cmp");
for ($x=3;$x<sizeof($names);$x++){
echo $names[$x]."<br />";
}

That is what I used in the end, thank you very much!
