Run Shell Scripts and Open Shell Files in PHP
PHP allows us to use shell_exec();the shell function to process files. However, if your operating system is Windows, you should consider using the popen()and pclose()functions, because pipes are executed in text mode, which usually prevents their binary output.
We will implement two scripts in our shell.php./openfile.txt file. First, we will use the shell_exec();./openfile .shfunction.
We will then use shell_exec()to open a cmd interface and run some windows commands.
shell_exec()Run the shell file in text mode
using
Function Syntax and Parameters: shell_exec(string $cmd);. This function returns the shell output in string format.
We created a demo demo.shfile in this tutorial.
Code ( demo.sh):
#!/bin/sh
echo "Hello world";
echo "This is a shell .sh file for demo";
// your shell commands go here
You can create a .txt file using any text editor .shand .shsave it with the .txt file extension. After that, run the following PHP script ( shell.php) to open it in Notepad as it will throw in the string formatting in text mode.

<form action="shell.php" method ="post" align="center">
<input type="submit" value="Open .sh file using shell_exec() in PHP" name="openshellfile" />
<input type="submit" value="Run cmd/shell on Windows using shell_exec() in PHP" name="opencmd" />
</form>
</body>
</html>
<?php
// When user submits the form
if(isset($_POST['openshellfile'])){
echo $res=shell_exec('PATH to the file/demo.sh');
}
?>
Output:
Use in CLI shell_exec()to return binary format
shell_exec()Functions can be used for a variety of things. Our method is shell_exec()a great way to use without having to run a function in the background.
You also don't need to use popen()or pclose().
<?php
// Ping facebook cmd (shell)
// open cmd shell
if (isset($_POST['opencmd']))
{
//You do not need to use popen() or pclose() either to run this shell command
// you can add any command here, it will work!
//For example, you can control your Windows (CLI)
//You will only change the command after cmd.ex /k "Your Command"
$open = shell_exec('start cmd.exe /k ping "facebook.com"');
echo $open;
//function shell($open) {
//check your php version
}
?>
While we could have run any command with our script, we only used ping facebook.com. For example, if you wanted to open a calculator through this function, enter calcinstead of ping "facebook.com".
Before adding the above code in your PHP script, you first need to change the name of the input field in the HTML. Then add the above code to shell.phpthe file we ran earlier.
The scope of the command can be anything, you can type any windows command and assign it to $openthe variable. The script will run your command directly to the Windows shell (CLI in this example).
Output:
shell_exec();We executed a cmd command to ping in the above code
using facebook.com. However, you can type any command in the function argument and it will work.
