html - Format PHP database data -

-

what know when grab data database how can format php looks nice. seem getting blank white page , when inspect page google chromes inspect element says i've got 500 internal error.

for example, i'm using pdo connect database. heres code:

<?php $hostname='localhost'; $username='root'; $password='root';  try { $dbh = new pdo("mysql:host=$hostname;dbname=fitness", $username, $password); $sql = "select * fitness"; $fitnessresult = $dbh->query($s ql); $fitness = $dbh->fetchobject($fitnessresult); foreach ($fitness $fit) { $fitnessarray[] = ['name' => $fit->name, 'id' => $fit->description]; } $dbh = null; } catch (pdoexception $e) { echo "error is: " . $e-> etmessage(); }

and here html im using twitter bootstrap framework.

<?php include'inc/connect.inc.php'; ?>  <!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <title>fitness</title>  <!-- latest compiled , minified css --> <link rel="stylesheet"  href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css">  <!-- optional theme --> <link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap-  theme.min.css">  <link rel="stylesheet" href="css/style.css" />  <!-- latest compiled , minified javascript --> <script src="//netdna.bootstrapcdn.com/bootstrap/3.1.1/js/bootstrap.min.js"></script>  </head> <body>  <div class="container">  <div class="row"> <div class="col-xs-4"> <?php foreach ($fitnessarray $fitness) { echo '<h2>'. $fitness['name'] .'</h2>'; echo '<p>' . $fitness['description'] . '</p>';} ?> </div> <div class="col-xs-8">     <p>dummy text</p> </div> </div> </div> </body> </html>

so how put name h1 tag , description p tag.

thanks

you might want try following keeps objects , fetchs in arrary

$fitnessresult = $dbh->query($sql); $fitnessarray = $fitnessresult->fetchall(pdo::fetch_obj);

then in html

<?php foreach ($fitnessarray $fitness): ?>   <h2><?=$fitness->name ?></h2>   <p><?=$fitness->description ?></p> <?php endforeach; ?>

see official docs fetchall()

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
