Just off the top of my head if I wanted a quick random number, I'd probably just use
PHP Code:
echo $szString = str_shuffle(time());
// or for a little more random
echo $szString = str_shuffle(mktime(0, 0, 0, mt_rand(1, 12), mt_rand(1, 30), mt_rand(1980, 2010)));
...but the function I use for random strings looks more like this:
PHP Code:
static function generateRandStr ($intLength, $intEncode=0) {
// Initialize the string
$szRand = (string) "";
// Generate a fairly random string
for ($i = 0; $i < $intLength; $i++) {
$intRand = mt_rand(0,62);
// 0 thru 9
if ($intRand < 10) {
$szRand .= chr($intRand+48);
// A thru Z
} else if( $intRand < 36) {
$szRand .= chr($intRand+55);
// a thru z
} else {
$szRand .= chr($intRand+61);
}
}
// Determine if the string should be hashed
if ($intEncode == 1) return md5($szRand);
if ($intEncode == 2) return sha1($szRand);
return $szRand;
}
