Warning: chmod() has been disabled for security reasons in_PHP教程

Warning: chmod() has been disabled for security reasons in D:\freehost\xxx\WindFile.php on line 102 According to the English meaning, we know that chmod() has been disabled for security reasons, then The solution is very simple, just disable chmod().

If you have server permissions, the operation method is very simple. Open PHP.INI and find this line:

The code is as follows

Copy code

代码如下	复制代码
disable_functions =

disable_functions =

Add the functions to be disabled at the end. If you want to disable multiple functions, use half-width commas to separate them

Give me an example:

代码如下	复制代码
disable_functions = passthru,exec,system,popen,chroot,scandir,chgrp,chown,escapesh ellcmd,escapeshellarg,shell_exec,proc_open,proc_get_status

The code is as follows	Copy code
disable_functions = passthru,exec,system,popen,chroot,scandir,chgrp,chown,escapesh ellcmd,escapeshellarg,shell_exec,proc_open,proc_get_status

If you don’t have server permissions, you can only start with the program. Below I use ecmall to solve this problem

代码如下	复制代码
if ($errno == 2048)     {         return true;     }

Step one: Find eccore/controller/message.base.php

Will

代码如下	复制代码
if ($errno == 2048 || (($errno & error_reporting()) != $errno))     {         //不再需要通过_at方法来抵制错误         //错误被屏蔽时就不抛出异常，该处理就允许你在代码中照常使用error_reporting来控制错误报告         return true;     }

The code is as follows	Copy code
if ($errno == 2048) {         return true; }

Replace

代码如下	复制代码
function _at($fun) {     $arg = func_get_args();     unset($arg[0]);     restore_error_handler();     $ret_val = @call_user_func_array($fun, $arg);     reset_error_handler();     return $ret_val; }

with

The code is as follows

Copy code

if ($errno == 2048 || (($errno & error_reporting()) != $errno))

代码如下	复制代码
function _at($fun) {     $arg = func_get_args();     unset($arg[0]);     $ret_val = @call_user_func_array($fun, $arg);     return $ret_val; }

{ ​​​​ //No more need to use _at method to resist errors ​​​​ //No exception will be thrown when the error is masked. This processing allows you to use error_reporting in the code as usual to control error reporting         return true; }

Step 2: Find eccore/ecmall.php

The code is as follows	Copy code
function _at($fun) { $arg = func_get_args(); ​ unset($arg[0]); Restore_error_handler(); $ret_val = @call_user_func_array($fun, $arg); ​ reset_error_handler(); return $ret_val; }

was changed to

The code is as follows	Copy code
function _at($fun) { $arg = func_get_args(); ​ unset($arg[0]); $ret_val = @call_user_func_array($fun, $arg); return $ret_val; }

We try our best to avoid some dangerous functions during development to avoid having to change them later. Below I list the functions that are prohibited by general servers

The code is as follows

代码如下

复制代码

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
