1. mysql_fetch_arrayµÄº¯ÊýÔÐÍÊÇ
array mysql_fetch_array ( resource $result [, int $result_type= MYSQL_BOTH ] )
Returns an array that corresponds to the fetched row and moves the internal data pointer ahead.
The type of returned array depends on how result_type is defined. By using MYSQL_BOTH (default), you'll get an array with both associative and number indices. Using MYSQL_ASSOC, you only get associative indices (as mysql_fetch_assoc() works), using MYSQL_NUM, you only get number indices (as mysql_fetch_row() works).
