What are the potential reasons for data not being saved to the database even when the SQL statement returns true in PHP?

The potential reasons for data not being saved to the database even when the SQL statement returns true in PHP could be errors in the SQL query, issues with database connection, or insufficient permissions. To solve this issue, you should check for any error messages returned by the database and ensure that the connection is established successfully before executing the query. 

// Check for errors in SQL query execution
if ($conn->query($sql) === TRUE) {
    echo "Record saved successfully";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}
