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
