mysql_field_type (PHP 3, PHP 4, PHP 5) mysql_field_type --
取得結果集中指定欄位的類型
說明string mysql_field_type ( resource result, int field_offset )
mysql_field_type() 和
mysql_field_name()
函數相似。參數完全相同,但返回的是欄位類型而不是欄位名。欄位類型有「int」,「real」,「string」,「blob」以及其它,詳見
MySQL 手冊。
例子 1. mysql_field_type() 例子
<?php mysql_connect("localhost", "mysql_username", "mysql_password"); mysql_select_db("mysql"); $result = mysql_query("SELECT * FROM func"); $fields = mysql_num_fields($result); $rows = mysql_num_rows($result); $table = mysql_field_table($result, 0); echo "Your '".$table."' table has ".$fields." fields and ".$rows." record(s)\n"; echo "The table has the following fields:\n"; for ($i=0; $i < $fields; $i++) { $type = mysql_field_type($result, $i); $name = mysql_field_name($result, $i); $len = mysql_field_len($result, $i); $flags = mysql_field_flags($result, $i); echo $type." ".$name." ".$len." ".$flags."\n"; } mysql_free_result($result); mysql_close(); ?>

以上例子將產生如下輸出:
Your 'func' table has 4 fields and 1 record(s)
The table has the following fields:
string name 64 not_null primary_key binary
int ret 1 not_null
string dl 128 not_null
string type 9 not_null enum |

為向下相容仍然可以使用
mysql_fieldtype(),但反對這樣做。
