The Mysql_num_fields () function can count the number of all fields in the table that will be queried, and the syntax of the function is as follows:

int Mysql_num_fields (Resource $result)

Where the parameter result is the result set returned after the mysql_query () function executes. The sample code for getting the number of fields in PHP using the Mysql_num_fields () function is as follows:

   "Root", "root") or Die ("Connection Server failed");
6. mysql_select_db ("Sunyang", $connection)
   Or Die ("Select Database Failed");
8. $ Query = "SELECT * FROM Employee" ;
10. $ result = mysql_query ($query) or
    Die ("Query data Failed"); Execute Query
12. echo Mysql_num_fields ($result);
    Number of output fields
14. Mysql_free_result ($result);
16. Mysql_close ();
