[英]Do I need to configure my remote server when using shell_exec();
I am trying to encrypt a string using a command created in C in my remote server where my database is located. 我正在尝试使用在数据库所在的远程服务器中的C中创建的命令来加密字符串。 But shell_exec keeps giving me a call to undefined function error.
但是shell_exec不断给我一个未定义函数错误的调用。 What are the steps to make this function defined?
定义此功能需要执行哪些步骤? Am I using this function correct?
我使用此功能正确吗?
function encrypt($string) {
$output = shell_exec('');
echo "<pre>$output</pre>";
}
$string = "some_string";
$encryptedString = encrypt($string);
You need to blacklist the shell_exec
from the safe mode
. 您需要从
safe mode
将shell_exec
列入黑名单。
Sidenote : If it works, you need to escape the $string
using the escapeshellarg()
before passing it to your shell_exec()
function. 旁注 :如果
escapeshellarg()
,则需要在将$string
传递给shell_exec()
函数之前使用$string
escapeshellarg()
对其进行转义。
Like this.. 像这样..
function encryptTFS($string) {
$output = shell_exec('tea32 -e -"'.escapeshellarg($string).'" -ofilenameoutout');
echo "<pre>$output</pre>";
}
$string = "some_string";
$encryptedString = encryptTFS($string);
