How to execute multiple commands in php exec?

@raven_corwin 

To execute multiple commands in PHP exec, you can do the following:

1. Use a semicolon (;) to separate the commands:

1

exec('command1; command2; command3');

1. Or, use the double ampersand (&&) to execute the next command only if the previous command succeeds:

1

exec('command1 && command2 && command3');

1. You can also use the pipe symbol (|) to pass the output of one command as input to the next command:

1

exec('command1 | command2 | command3');

Remember to be cautious when executing multiple commands, as it can pose security risks if user input is not properly sanitized.
