    <p>I am trying to pull out data from my database using php and exporting it into a downloadable CSV file that can be opened with excel. I am able to do this when i use mysql however, many have advised to not include mysql syntax in my code as its being deprecated and instead i should use mysqli. I have changed my code but now my code is not working. Does anyone know why that is?</p> <p><strong>mysql version (working version)</strong>`</p> <pre><code>mysql_connect('localhost', 'xxxxx', 'xxxxx') or die('connect'); mysql_select_db('db') or die('select'); $result = mysql_query('SELECT * bodyshops_master_network') or die('query'); if(mysql_num_rows($result) == 0) { die('no data'); } $fh = tmpfile() or die('tmpfile'); $cols = array_keys(mysql_fetch_assoc($result)); fputcsv($fh, $cols); mysql_data_seek($result, 0); // set result row pointer back to first row while($row = mysql_fetch_assoc($result)) { fputcsv($fh, $row); } rewind($fh); $text = fread($fh, 999999); header('Content-Type: text/csv'); header('Content-Disposition: attachment; filename="download.csv"'); header('Content-Length: ' . strlen($text)); echo $text; exit; </code></pre> <p><strong>mysqli version (not working):</strong></p> <pre><code>$mysqli = new mysqli("localhost", "xxxxx", "xxxxx", "db"); if (mysqli_connect_errno()) { printf("Connect failed: ", mysqli_connect_error()); exit(); } else { $result = "SELECT * FROM bodyshops_master_network"; if(mysqli_num_rows($result) == 0) { die('no data'); } $fh = tmpfile() or die('tmpfile'); $cols = array_keys($result-&gt;fetch_assoc()); fputcsv($fh, $cols); $result-&gt;data_seek(0); // set result row pointer back to first row while($row = $result-&gt;fetch_assoc()) { fputcsv($fh, $row); } rewind($fh); $text = fread($fh, 999999); header('Content-Type: text/csv'); header('Content-Disposition: attachment; filename="download.csv"'); header('Content-Length: ' . strlen($text)); echo $text; exit; </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
