------ Solution --------------------
The data from the database, isn't it an array.
Is an array of keys and numbers.
The field depends on the order of the fields you query !!!
------ Solution --------------------
It seems that there is a function called
Mysql_field_name ();
This function returns the field name of the resource set.
That is, you first run the SQL query
Save the query result to a variable.
Use this variable and an integer as the parameter.
Input this function
The integer value should be the offset of the field name.
For example, if you input 0
Mysql_field_name ($ res, 0 );
It is obtained from the first field name of the $ res dataset.
You can search for the usage of this function.
Or test it by yourself.
Try it.
