编写没有mod_rewrite的动态URL路径

So, right now I'm trying to generate dynamic URLs as well as their paths without using .htaccess or the use of modules. Basically, I'm trying to rewrite and output URL paths that work statelessly on different localhosts served by Apache.

I would like to have an index.php that gets URIs through a query string like this (obviously not code):

-> index.php  (echos dynamically generated URL hyperlinks)      
-> index.php?q=/   (echos every URI in JSON)                       
-> index.php?q=/some_id   (outputs table some_id info w/ links to reviews)                            
-> index.php?q=/some_id/reviews    (outputs table column of reviews w/ link to review_ids)                    
-> index.php?q=/some_id/reviews/review_id   (output related column info)

Could someone walk me through how I'd go about doing this? I figure I'm going to have to write the URL using $_SERVER methods and explode while iterating through an array of table IDs..?

Any help is greatly appreciated!

EDIT:
Here's the code I was trying to write :/

  <?php
     $db = $user = $pw = 'logininfo';

     try {
        $dbconn = new PDO('mysql:host=localhost;db='.$db, $user, $pw;   
     }
     catch (Exception $e) {
        echo "Error: ";
        echo $e->getMessage();
     }
  ?>

  <!DOCTYPE HTML>
  <head>
      <title>Product Reviews</title>
  </head>
   <body>
     <h1>Product List:</h1>
        <h2>
           <ul>
              <?php    
                  try {
                     $sql = "SELECT somename, some_id FROM products";
                 $stmt = $dbconn->query($sql);
                 if($stmt !== false) {
                 foreach($stmt as $row) {  //output just name
                     echo "<li>";
                 echo htmlentities($row['somename'])."<br />";

                 if($stmt !== false) {
                    $url = "<a href=index.php?q=".
                                htmlentities($row['some_id'])."/>".
                                htmlentities($row['somename'])."'s Review</a>";

                    echo $url;         //output URL
                    echo "</li>"."<br />";
                 }
                 else {
                    echo "Unnecessary";
                 }
                 }
                 if($_GET['url']) {   //don't really know what to put here
                    header("Location: $url");   //can't use headers anyway
                 }  
                }
                $stmt = null;
                 }
                 catch (PDOEXCEPTION $e) {
                echo $e->getMessge();
                 }
         ?>
    </ul>
    </h2>
   </body>
  </html>

    You can write URLs as :

    http://example.org/index.php/reviews/id/ [where id can be your review id]

    and use $_SERVER['PATH_INFO'] in index.php to get part of URL which is after index.php, then explode the text and get desired data out of it.

    <?php
    $query_string = explode('/', $_SERVER['PATH_INFO']);

    switch(count($query_string)) {
        case 2:
            $some_id = (int) $query_string[1];
            if ($some_id === 0) {
                //(echos every URI in JSON)

            }
            else {
                // (outputs table some_id info w/ links to reviews)

            }

            break;

        case 3:
            //(outputs table column of reviews w/ link to review_ids)
            $some_id = (int) $query_string[1];
            $table_name = $query_string[2];
            break;

        case 4:
            //(output related column info)
            $some_id = (int) $query_string[1];
            $table_name = $query_string[2];
            $review_id = (int) $query_string[3];
            break;

        default:
            // Error case
    }
?>
