php - How do i get databasevalues in my website by using a var? -

we doing project using flipcards show questions , flip on see answer. have use database , managed add category , questions , answers database.

but want questions , answers out of database , place them on our flashcards. cant seem right.

this have :

index.php

foreach($acategories $acategory) {                 $name = $acategory['id'];                 echo "<div class='col-md-3 col-xs-6'><a href='/oefenen/vraag-1' name='$name' class=\"btn btn-info\">".$acategory['name']."</a></div>";             } 

oefenen_controller.php

public function indexaction() {     $odatabase = new database();     $this->userloggedin();      $acategories = $odatabase->getcategories();     $this->set("acategories", $acategories);      $avragen = $odatabase->getvragen();     $this->set("avragen", $avragen);  } 

in index.php tried use name='$name' values out of database, doesnt seem work. on our cards shows hard coded questions used examples, not questions try out of database.

is there understands our question , knows how ? or maybe can on our way ?
