I have the following code:

So if i entered this url:
http://localhost/?function=phpinfo

I will see the phpinfo function output on the screen.

can i have a way to concatenate 2 function in the url like this example:

http://localhost/?function=shell_exec('ls') AND phpinfo

So i want to see the first function output..

If you may asking why i need this, is because i am pen testing an web application with this situation.

that looks very dangerous. you can pass a string separated with semicolon for each function, like:

http://localhost/?function=shell_exec('ls');phpinfo

then:

if(isset($_GET['function'])){
        $functions =  explode(';',$_GET['function']);
        foreach($functions as $function){
                $function();
        }
}

or you can use eval function:

http://localhost/?function=eval("shell_exec('ls');phpinfo();")
