使用PHP在命令提示符下运行.bat文件

Question

I need to run a .bat file in a command prompt whenever I click a button or hyperlink. The code I've written is:

<?php
    if(isset($_POST['submit']))
    {
        $param_val = 1;
        $test='main.bat $par'; 
        // exec('c:\WINDOWS\system32\cmd.exe /c START C:/wamp/www/demo/m.bat');    
        // exec('cmd /c C:/wamp/www/demo/m.bat');
        // exec('C:/WINDOWS/system32/cmd.exe');
        // exec('cmd.exe /c C:/wamp/www/demo/main.bat');
        exec('$test');
    } 
    else
    {
        ?>

        <form action="" method="post">
        <input type="submit" name="submit" value="Run">
        </form>

        <?php
    }
?>

my main.bat is:

@echo off
cls
:start
echo.
echo 1.append date and time into log file
echo 2.just ping google.com

set/p choice="select your option?"

if '%choice%'=='1' goto :choice1
if '%choice%'=='2' goto :choice2
echo "%choice%" is not a valid option. Please try again.
echo.
goto start
:choice1
call append.bat
goto end
:choice2
call try.bat
goto end
:end
pause

When I click the run button it has to open the command prompt and run the main.bat file, but whenever I click run it says nothing.

Answer 1

$test='main.bat $par';
exec('$test');

... won't work.

PHP only takes $variables in double quotation marks.

This is bad practice also: $test = "main.bat $par";.

Also windows takes backslashes instead of slashes which need to be escaped through another backslash in double quotes.

Use one of these:

$test = 'cmd /c C:\wamp\www\demo\main.bat ' . $par;

or

$test = "cmd /c C:\\wamp\\www\\demo\\main.bat {$par}";

run:

echo shell_exec($test);

Even more fails:

Remove the pause from the end of your script. PHP does not get arround that automatically.

Looking more at the batch file, I bet you don't even need it. Everything inside the batch file can be put into a PHP file.

As Elias Van Ootegem already mentioned, you would need to pipe in STDIN to enter your option (1, 2) into the batch file.
