PHP disabling function setting and viewing methods _php tips

This example describes the PHP disabling function settings and viewing methods. Share to everyone for your reference, specific as follows:

Open PHP.ini and find this line:

Disable_functions =

Add the function you want to disable in the back, such as disabling multiple functions, using a half-width comma to separate

Give an example:

Copy Code code as follows:

Disable_functions = Passthru,exec,system,popen,chroot,scandir,chgrp,chown,escapesh
Ellcmd,escapeshellarg,shell_exec,proc_open,proc_get_status

Recommended functions that are disabled on the host:

Copy Code code as follows:

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
