[5] => strcmp
[6] => strncmp
[7] => strcasecmp
[8] => strncasecmp
[99] => variant_cmp
[403] => strnatcmp
[404] => strnatcasecmp
[1211] => gmp_cmp
vs
[431] => substr_compare
[869] => version_compare
[1302] => collator_compare
[1428] => ldap_compare
var_cmp() looks a LOT like variant_cmp() (Windows only - a function in
the COM/DOTNET extension)
and
variable_compare($a,$b) is actually longer than ($a<$b?-1:(($a>$b)1:0)
But var_cmp() would be my +1
