Re: sorting multi-dimensional arrays

Try this (it should work): while(list($k, $v) = each($myarray)){ $myarray[$k] = (int) $v; } arsort($myarray); reset($myarray); while(list($k, $v) = each($myarray)){ echo $k, ' == ', $v, "<BR>\n; } For better comprehension look at this post: >Hey guys.. > >I have this array that looks like this: > >$myarray = ( "apples" => 0, "oranges" => 2, "peaches" => >9, "pineapples" => >12, "stovetopstuffing" => 3, "grits" => 8); > >Fine and dandy.

What do I need to do? You have stored strings as your values, instead of ints. IE: (string) '9' > (string) '12' returns TRUE You will need to take care in creating your array to have (int) values instead of strings. If all else fails, the following should work: while(list($k, $v) = each($myarray)){ $myarray[$k] = (int) $v; } arsort($myarray); reset($myarray); while(list($k, $v) = each($myarray)){ echo $k, ' == ', $v, "<BR>\n; } ----- Original Message ----- From: <Shane43@aol.com> To: <php-general@lists.php.net> Sent: Saturday, April 14, 2001 5:19 AM Subject: [PHP] sorting multi-dimensional arrays > I have a question about sorting multidimensional arrays.
