I needed to be able to sort a string that contained numbers eg.
"Slot 1 name"
"Slot 2 name"
"Slot 10 name"
using a normal string compare the "Slot 10 name" would appear before "Slot 2
name" so I wrote little function that will compare a string taking numbers in to consideration.
There may be a few edge cases that need to be taken in to consideration.
function strCmpWithNumbers( $a, $b) {
// Split the string in to words.
$a = explode(' ',$a);
$b = explode(' ',$b);
$loop = 0;
do {
// Get the first word from each item
$ta = Utils::gvfa($a, $loop);
$tb = Utils::gvfa($b, $loop);
if (isset($ta)) {
if (isset($tb)) {
if (is_numeric($ta)) {
if ($ta != $tb) {
return $ta - $tb;
}
} else {
$val = strcasecmp($ta, $tb);
if ($val != 0) {
return $val;
}
}
} else {
return 1; // a is set but b isn't
}
} else {
return isset($b);
}
$loop +=1;
} while (true);
}
