Message:

I am trying to assign parameters listed in the URL save into my variables. You can see the procedure here:

<?php



$browser;

$version;

$page;



foreach($_GET as $key => $value) {

  if (strcmp($key, "browser")) {

    $browser = $value;

  }

  elseif (strcmp($key, "version")) {

    $version = $value;

  }

  elseif (strcmp($key, "page")) {

    $page = $value;

  }

}



echo $browser;

echo $version;

echo $page;

?>

But unfortunately, it only prints out the browser and the version. The page does not appear. Yes, the page parameter is definitely written correctly in the URL. If I change code like this, the variables get printed out correctly:

 <?php

    

    foreach($_GET as $key => $value) {

      if (strcmp($key, "browser")) {

        echo $value;

      }

      elseif (strcmp($key, "version")) {

        echo $value;

      }

      elseif (strcmp($key, "page")) {

        echo $value;

      }

    }

    ?>

Thanks in advance.

My Answer:
php
// Get the parameters from the URL
$param1 = $_GET['param1'];
$param2 = $_GET['param2'];

// Check if the parameters are set
if(isset($param1) && isset($param2)) {
// Assign the parameters to variables
$variable1 = $param1;
$variable2 = $param2;

// Use the variables for further processing
echo "Variable 1: " . $variable1 . "
";
echo "Variable 2: " . $variable2 . "
";
} else {
echo "Parameters not set in the URL";
}


Make sure that the parameters `param1` and `param2` are passed in the URL in the following format: `http://example.com/script.php?param1=value1¶m2=value2`. If the parameters are not set in the URL, the script will output "Parameters not set in the URL".
