I missed the original post, and I'm too lazy to go looking, but the
following code runs in approx. 2.75 seconds on my Athlon 2400 running
linux:
$chars = '0123456789'
.'abcdefghijklmnopqrstuvwxyz'
.'ABCDEFGHIJKLMNOPQRSTUVWXYZ';
$charArray = array();
for( $i = 0; $i < 1000000; $i++ )
{
$charArray[] = $chars[rand( 0, 61 )];
}
It's runs much faster than using a .= style of string creation.
Cheers,
Rob.
