Printing mysql_error
This is a code snipped to print mysql error.
If there is no error mysql_error returns null, thus if evaluates false and there is no output.
If there is error previous mysql_query statement, if evaluates true. Since $my_sql_error is populated here, we can use inside of the if. $sSQL is sql query in error.
if($my_sql_error = mysql_error()){
echo $sSQL. "". $my_sql_error;
}
This kind of snipped if fits in a print_mysql_funciton may be much more usefull. But it were some kind of logging facility yemede yanında yat.
