since my old entry got deleted, because it was too long, and since i got so much feedback, i'll
post the array_csort again.
if you want to sort an array by columns, this is the function to do it.
explanation & example (was too long...) now here: http://www.ichier.de/coding/array_csort.html
<?php
function array_csort() { //coded by Ichier2003
$args = func_get_args();
$marray = array_shift($args);
$msortline = 'return(array_multisort(';
foreach ($args as $arg) {
$i++;
if (is_string($arg)) {
foreach ($marray as $row) {
$sortarr[$i][] = $row[$arg];
}
} else {
$sortarr[$i] = $arg;
}
$msortline .= '$sortarr['.$i.'],';
}
$msortline .= '$marray));';
eval($msortline);
return $marray;
}
?>
