linux - PHP domain availability script exec() function alternative -
i want install php whois domain availability check script on website found somewhere.
it has whois_class.php file allows switch between "win" & "linux" mode.
when switch on "win" mode works fine in localhost using windows os.
but when upload server stops working server linux server.
so have switch "linux" mode , re-upload whois_class.php. expected work fine linux mode developer of script has used exec() function host has disabled security purposes.
so, option guess if change server platform linux windows. but, mess.
i looking way how can use script run smoothly on linux server runs on localhost in windows os. change or modification script make run appreciated.
whois_class.php :

system,exec,shell_exec,passthru,popen,proc_open,pcntl_exec,highlight_file,show_source,symlink,link,posix_getpwuid,posix_getpwnam,posix_getgrgid,posix_getgrnam,posix_kill,posix_mkfifo,posix_getrlimit
there plenty of functions related program execution. should check other functions disabled on setup:
var_dump(ini_get("disable_functions"));
