Matt,
Personally, I'd do a logic case for each combination, e.g.
if (ctype_alpha($x[0])) {
if (ctype_alpha($y[0])) {
//strcmp
} elseif (ctype_digit([$y[0])) {
//-1
} else {
// 1;
}
} elseif (ctype_digit([$x[0])) {
if (ctype_alpha($y[0])) {
// 1;
} elseif (ctype_digit([$y[0])) {
// >
} else {
// 1;
}
} else {
if (ctype_alpha($y[0])) {
// -1;
} elseif (ctype_digit([$y[0])) {
// -1
} else {
// strcmp
}
}
It's not the prettiest, but it will work.
