How to Display Data from SQL Database in PHP/HTML Table?

Displaying Data from SQL Database in PHP/HTML Table

In PHP, connecting to a MySQL database and displaying data from it into an HTML table can be achieved using the following steps:

<code class="php">$connection = mysql_connect('localhost', 'root', ''); //The Blank string is the password
mysql_select_db('hrmwaitrose');

$query = "SELECT * FROM employee"; //You don't need a ; like you do in SQL
$result = mysql_query($query);

echo "<table>"; // start a table tag in the HTML

while($row = mysql_fetch_array($result)){   //Creates a loop to loop through results
echo "<tr>
<td>" . htmlspecialchars($row['name']) . "</td>
<td>" . htmlspecialchars($row['age']) . "</td>
</tr>";  //$row['index'] the index here is a field name
}

echo "</table>"; //Close the table in HTML

mysql_close(); //Make sure to close out the database connection</code>

In this code:

• We connect to the database using mysql_connect(), providing the host, username, and (empty) password.
• We select the hrmwaitrose database using mysql_select_db().
• We execute an SQL query to retrieve all rows from the employee table using mysql_query().
• We then use a while loop to iterate through the results, generating HTML table rows () with data columns () for each row.
• We escape the data using htmlspecialchars() to prevent XSS attacks.
• Finally, we close the table and the database connection.

This code provides a simple template for displaying data from a MySQL database into an HTML table in PHP. Please note that mysql_fetch_array is deprecated in PHP 7.0.0 and later, so you may need to use mysqli_fetch_array() instead.
