How can proper error handling be implemented in PHP when executing MySQL queries to troubleshoot issues like the one described in the forum thread?

Issue: Proper error handling in PHP when executing MySQL queries can be implemented by checking the result of the query execution and displaying error messages if the query fails. This helps in troubleshooting issues like the one described in the forum thread where the query was not executing as expected. Solution: 

// Connect to MySQL database
$mysqli = new mysqli("localhost", "username", "password", "database");

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

// Execute MySQL query
$query = "SELECT * FROM table";
$result = $mysqli->query($query);

// Check if query was successful
if ($result === false) {
    die("Error executing query: " . $mysqli->error);
}

// Process query results
while ($row = $result->fetch_assoc()) {
    // Do something with the data
}

// Close connection
$mysqli->close();
