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 !!!

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.
