call this function with url parameter

How t开发者_如何学Pythono call this function with url parameter

function test($str, $str_){

     if ($str == $str)
     echo "null";
     else
     echo "helloworld";
}

---

Use this:

switch($_GET['cmd']) {
case 'hello':
    test($_GET['cmd'],'second_parameter_value');
}

The problem is that you aren't passing a value for the second parameter. I execute previous code and prints "helloworld"

Second part:

If your intention is to call the function using two parameters in the Url you can use the follow (I'm only modifying the important parts in your own initial code):

function test($str, $str_){

     if ($str == "null")
        echo "null";
     else
        echo "helloworld";
}

switch($_GET['cmd']) {
case 'hello':
    test($_GET['cmd'],$_GET['cmd2']);
}

and the Url to call this is: execute.php?cmd=hello&cmd2=hello2

The function is defined with two parameters, but you have only passed in one.

This will cause a fatal error and PHP stop execution - you should get an error message to this effect, if you are not it would be advisable for you to turn on display_errors in php.ini, or you can put the line ini_set('display_errors',TRUE); at the top of your script.

Try this:

function test ($str) {
  if ($str == "null") {
    echo "null";
  } else {
    echo "helloworld";
  }
}

switch ($_GET['cmd']) {
  case 'hello':
    test($_GET['cmd']);
    break;
  default:
    echo "No match in switch structure";
}

function Init()
{
   if(isset($_GET['cmd']))
     {
       $command = $_GET['cmd'];
       switch($command)
       {
           case 'hello':
              test($command);
           break;
          default:
            echo 'hello world';
       }
    } else {
      echo 'Enter Command';
    }
}
function test($cmd)
 {
   echo 'Command: ' . $cmd;
}
Init();

Maybe this can help you

Try this one

$urlParams = explode('/', $_SERVER['REQUEST_URI']);
$functionName = $urlParams[2];
$functionName($urlParams);


function func1 ($urlParams) {
    echo "In func1";
}

function func2 ($urlParams) {
    echo "In func2";
    echo "<br/>Argument 1 -> ".$urlParams[3];
    echo "<br/>Argument 2 -> ".$urlParams[4];
}

and the urls can be as below
http://domain.com/url.php/func1
http://domain.com/url.php/func2/arg1/arg2
