<input type='button' id=<?= $yourId ?> class='btn btn-info' data-target=<?= $dataYouWantToSend ?> onclick=show(this) value='Details'>


<script>
           function show(x)
           {

               x.innerHTML=x.data-target;  //data-target is equal to the data you want to send to function this will add innerHTML = your dynamic data 
               console.log(x.id); //here you will get your dynamic id

           }
   </script>

Modify your code as shown above , and It will work for sure , see you can not write html code in php "echo" , instead you should go for where you want php code in HTML

Second thing suppose you want to send data to function then assign your data to the new attribute like you have written data-target

and pass the function "This" , this means the current element , in your case its button

Then access your data and id by " . " operator for e.g. x.id

I hope it will help you :)

Remember : <?php echo "HII" ; ?> can be written as <?= "Hii" ?>

If you really want to get Id of element, based on what I guess about what you want to do you have to surround it with quotation marks (fix this part): onclick='"show($butid)"' .
