------ 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.
