get error throwing php script name inside class - php

Question

I am using Bennett Stone php wrapper class for mysqli operations. class is working fine without any issues. There is a function inside it (shared below) which sends an email to administrator for any kind of mysqli errors.
Issue
There are 100's of scripts using this class, I am not able to find out which script thrown any particular error.
What i want
I want to get the full path of error originating script inside class from where query originated. for example, test.php contains query & post execution if any error comes out then i want complete path of test.php inside error handling function along with error details (shared below).
What i can do
Class modification I can do by my own
I am getting details like this:
Error at 2016-08-23 05:44:18:
Query: SELECT email FROM users WHERE
Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1
Error handling function
public function log_db_errors( $error, $query )
{
$message = '<p>Error at '. date('Y-m-d H:i:s').':</p>';
$message .= '<p>Query: '. htmlentities( $query ).'<br />';
$message .= 'Error: ' . $error;
$message .= '</p>';
if( defined( 'SEND_ERRORS_TO' ) )
{
$headers = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
$headers .= 'To: Admin <'.SEND_ERRORS_TO.'>' . "\r\n";
$headers .= 'From: systems<noreply#'.$_SERVER['SERVER_NAME'].'.com>' . "\r\n";
mail( SEND_ERRORS_TO, 'Database Error', $message, $headers );
}
else
{
trigger_error( $message );
}
if( !defined( 'DISPLAY_DEBUG' ) || ( defined( 'DISPLAY_DEBUG' ) && DISPLAY_DEBUG ) )
{
echo $message;
}
}

Answer 1

Put these lines somewhere above all your codes:
ini_set('display_errors', 0);
ini_set('log_errors', 1);
error_reporting(E_ALL);
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
and you will have every error logged with a stack trace. While all this bushy "log_db_errors" stuff will be thrown away.
the problem solved.
NB. This wrapper class is just terrible. Utilizes almost every bad practice ever exists.

What you can do is catching exception and edit error message, using some magic php const in it : PHP: Magic constants
Example, in your class, around the query :
try {
// your query
} catch (Exception $e) {
// launch your log_db_errors() function, with some of const, like __CLASS__, __LINE__, etc :
$error = '[' . __FILE__ . '][' . __CLASS__ . '::' . __FUNCTION__ . '][' . __LINE__ . '] : ' . $e->getMessage();
// ...
}
