sort problem

[ted_chou12]

I see that both sort and rsort both have some problem in ordering uppercase and lowercase, from what i see, they put lowercase first, and then comes the uppercase, despite the lowercase alphabet comes after the uppercase alphabet, why is that so, and can anyone suggest me how i can solve this?
Thanks

Use natcasesort() (http://www.php.net/manual/en/function.natcasesort.php) this will sort strings lexographrically.  The reason sort() sorts strings somewhat counter intuitively is that upper case chars have lower ascii values than lower case chars.

Best,

Normal sorting, sort ( $array) is UPPERCASE first. If you need [b]natural[/b] sorting, where as the sort is compared in lower case, that means UPPER CASE characters are compared as lower case characters (insensitive to case), then use...

[code]natcasesort ( $array );

OR

natsort ( $array );

// reset the keys after sorting

$array = array_values ( $array );

// to reverse the sort and reset the keys, change [b]false[/b] to [b]true[/b], to preserve the keys when reversing!

$array = array_reverse ( $array, false );[/code]

printf
