Create url using data fetched from database in my webpage

I have a database that has a table of assignments

CREATE TABLE `assignments` (
 `a_id` int NOT NULL AUTO_INCREMENT,
 `title` varchar(50) NOT NULL,
 `description` varchar(250) NOT NULL,
 `file` varchar(50) NOT NULL,
 ` deadline ` datetime NOT NULL,
 PRIMARY KEY (`a_id`)
)

in my website I would like to view assignments by title, then click on each title (title should be hyperlinked ) to be redirected to details of this specific assignment. here's what I've got so far

  // Get records from the database
    $query = $db->query("SELECT * FROM assignments ORDER BY a_id ASC ");
    
    if($query->num_rows > 0){ 
        while($row = $query->fetch_assoc()){ 
            $assigment_title = $row['a_id'];
           
    ?>
    <div class="list_item">
        <?php echo "<tr><td><a href= 'A i'>" . $row["title"]. "</a></td></tr>"; ?></div>

the problem is 'A i' part, what I want is for the href to change according to the title, I am new to php and I cannot find my workaround. assuming I have a list of urls: A 1,A 2,...A n TIA

Where and how is this Laravel kernel constructor called? public fucntion __construct(Application $app, $Router $roouter) { } I have read the documentation and some online tutorial but I can find any clear explanation. I am learning Laravel and I am wondering where does this kernel constructor receives its arguments from. "POSTMOTERM" CLARIFICATION: Here is more clarity.I have checked the boostrap/app.php and it is only used for boostrapping the interfaces into the container class. What is not clear to me is where and how the Kernel class is instatiated and the arguments passed to the object calling the constructor.Something similar to; obj = new kernel(arg1,arg2) or, is the framework using some magic functions somewhere? Special gratitude to those who burn their eyeballs and brain cells on this trivia before it goes into a full blown menopause alias "MARKED AS DUPLICATE". To some of the itchy-finger keyboard warriors, a.k.a The mods,because I believe in th...
