I have a binary that takes input from stdin that I use on the command line by piping file contents to it like cat query.sql | go-mysql-format, but how do I pipe a variable to the executable?
Currently I have
file_put_contents($File = "$_SERVER[DOCUMENT_ROOT]/tmp/" . uuid(), $MySQL);
$o = shell_exec('cat ' . escapeshellarg($File) . ' | go-mysql-format --html');
Basically I would like to skip the file creation.
It's also important to note that the data will contain newlines, so I'm not sure wrapping the variable with escapeshellarg will be appropriate
我有一个二进制文件，它通过将文件内容传递给它来获取我在命令行上使用的stdin的输入，就像< code> cat query.sql | go-mysql-format ，但是如何将变量传递给可执行文件？
目前我有
file_put_contents （$ File =“$ _SERVER [DOCUMENT_ROOT] / tmp /”。uuid（），$ MySQL）;
$ o = shell_exec（'cat'.escapeshellarg（$ File）。'| go-mysql-format --html '）;
基本上我想跳过文件创建。
同样重要的是要注意数据将包含换行符，因此我不确定用 escapeshellarg 包装变量是否合适
Thanks to the point in the right direction from @NigelRen to look at proc_open
I wrapped the steps in a function for me to use later, which might be helpful.
微信扫一扫function exec_stdin(string $Command, string $Data) {
$_ = proc_open($Command, [['pipe', 'r'], ['pipe', 'w'], ['pipe', 'w']], $p);
if (is_resource($_)) {
fwrite($p[0], $Data);
fclose($p[0]);
$o = stream_get_contents($p[1]);
fclose($p[1]);
$_ = proc_close($_);
return $o;
}
return false;
}
var_dump(exec_stdin('go-mysql-format', 'yeet'));
returns
string(7) "`yeet` "
which is exactly the output I needed!
