禁用php函数的设置

打开PHP.INI,找到这行:

disable_functions =



在后面那里加上要禁用的函数,如禁用多个函数,要用半角逗号 , 分开

  给个例子:
  disable_functions = passthru,exec,system,popen,chroot,scandir,chgrp,chown,escapesh
  ellcmd,escapeshellarg,shell_exec,proc_open,proc_get_status
  


  建议在主机上禁用的函数:
  disable_functions = system,exec,shell_exec,passthru,proc_open,proc_close,
proc_get_status,checkdnsrr,getmxrr,getservbyname,getservbyport, syslog,popen,show_source,highlight_file,dl,socket_listen,socket_create,socket_bind,socket_accept, socket_connect, stream_socket_server, stream_socket_accept,stream_socket_client,ftp_connect, ftp_login,ftp_pasv,ftp_get,sys_getloadavg,disk_total_space,
disk_free_space,posix_ctermid,posix_get_last_error,posix_getcwd, posix_getegid,posix_geteuid,posix_getgid, posix_getgrgid,posix_getgrnam,posix_getgroups,posix_getlogin,posix_getpgid,posix_getpgrp,posix_getpid, posix_getppid,posix_getpwnam,posix_getpwuid, posix_getrlimit,
posix_getsid,posix_getuid,posix_isatty, posix_kill,posix_mkfifo,posix_setegid,posix_seteuid,posix_setgid, posix_setpgid,posix_setsid,posix_setuid,posix_strerror,posix_times,posix_ttyname,posix_uname


  


  在主机上面如何查看禁用的函数列表,我从网上找了一个非常不错的探针
