To execute multiple commands using the exec() function in PHP, you can use one of the following methods:

  1. Separating commands with a semicolon (;):
exec("command1; command2; command3", $output, $status);

  1. Using the shell's command separator (&&) to run commands sequentially, where the next command will only be executed if the previous one succeeds:
exec("command1 && command2 && command3", $output, $status);

  1. Encapsulating multiple commands within curly braces ({}):
exec("{ command1; command2; command3; }", $output, $status);

Note: The $output variable is used to capture the output of the executed command(s), and the $status variable will contain the exit status code of the last command executed (0 for success).

However, it's important to exercise caution while executing multiple commands using exec() to prevent any security risks or unintended consequences. It's recommended to properly sanitize input and validate commands to minimize any potential vulnerabilities.
