How can the Zend Studio Debugger be utilized effectively to troubleshoot MySQL errors in PHP code?

To effectively troubleshoot MySQL errors in PHP code using the Zend Studio Debugger, you can set breakpoints in your code where database queries are executed and examine the values of variables to identify any issues. You can also use the debugger to step through the code line by line to pinpoint where errors may be occurring.

php 
<?php
// Connect to MySQL database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Query database
$sql = "SELECT * FROM table";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        echo "id: " . $row["id"]. " - Name: " . $row["name"]. "<br>";
    }
} else {
    echo "0 results";
}

// Close connection
$conn->close();
?>
