$query="SELECT * FROM president";
$result=mysql_query($query) or die("Query failed");
for($i=0;$i{
print("column $d:",$i);
printf("Name %s
",mysql_field_name($result,$i));
printf("Table %s
",mysql_field_nmae($result,$i));

(18) string mysql_field_type(int result_id, int col_num);
返回结果集给定列的类型名。类型名敬请等待参考本人的另外“MySQL列类型参考”。
col_num的范围为0到mysql_num_fields()-1.

$link=pconnect("localhost","sunsoft","suixiang") or die("Could not connect");
mysql_select_db("stamp_db");
$query="SELECT * FROM president";
$result=mysql_query($query) or die("Query failed");
for($i=0;$i{
printf("colum %d:",$i);
printf("Name %s,
",mysql_field_name($result,$i));
printf("Type %s
",mysql_field_type($result,$i));
}
?>

(19) string mysql_field_flags(int result_id, int col_num);
作为字符串返回结果集中给定列的相关元数据信息，如果出现错误，则返回假。这个字符串由以空格分开的词

组成，说明哪个列的标记值为真。对于假的标记，在字符串中给出相应的词。
col_num的范围为0到mysql_num_fields()-1.

$link=mysql_pconnect("localhost","sunsoft","suixiang") or die("Could not connect");
mysql_select_db("stamp_db");
$query="SELECT * FORM member";
$result=mysql_query($query) or die("Query failed");
for($i=0;$i{
printf("column %d:",$i);
printf("Name %s,
",mysql_fields_name($result,$i));
printf("Flags %s
",mysql_fields_flags($result,$i));
}
?>

(20) int mysql_field_len(int result, int field_offset);
返回结果集给定列中值可能的最大长度。
col_num的范围为0到mysql_num_fields()-1.

$link=mysql_pconnect("localhost","sunsoft","suixiang") or die("Could not connect");
mysql_select_db("stamp_db");
$query="SELECT * FROM member";
$result=mysql_query($query) or die("Query failed");
for($i=0;$i{
printf("Column %d:",$i);
printf("Name %s,
",mysql_field_name($result,$i));
printf("Len %d
",mysql_field_len($result,$i));
print"

";
}
