What common error message might you encounter when using the update function in PHP with MySQL?

One common error message you might encounter when using the update function in PHP with MySQL is "You have an error in your SQL syntax." This error typically occurs when there is a syntax error in your SQL query, such as missing quotes or incorrect table/column names. To solve this issue, you should carefully review your SQL query and make sure it is properly formatted. 

<?php
// Assuming $conn is your MySQL connection object
$id = 1;
$newValue = "updated value";

$sql = "UPDATE table_name SET column_name = '$newValue' WHERE id = $id";

if ($conn->query($sql) === TRUE) {
    echo "Record updated successfully";
} else {
    echo "Error updating record: " . $conn->error;
}

$conn->close();
?>
