本文實例講述了PHP中mysql_field_type()函數用法。分享給大家供大家參考。具體如下：
定義和用法:mysql_field_type() 函數返回結果集中指定字段的類型,如果成功,則返回指定字段的類型,如果失敗,則返回 false.
語法:mysql_field_type(data,field_offset)
| 參數 | 描述 |
| data | 必需,要使用的數據指針,該數據指針是從 mysql_query() 返回的結果. |
| field_offset | 必需,指示從哪個字段開始返回,0 指示第一個字段. |
復制代碼代碼如下:
<?php
mysql_connect("localhost","root","");
mysql_select_db("mydatabase");
$query = "SELECT id as ID, title FROM mytable ORDER BY title";
$result = mysql_query($query);
$row = mysql_fetch_row($result);
echo mysql_field_type($result, 0);
?>
mysql_connect("localhost","root","");
mysql_select_db("mydatabase");
$query = "SELECT id as ID, title FROM mytable ORDER BY title";
$result = mysql_query($query);
$row = mysql_fetch_row($result);
echo mysql_field_type($result, 0);
?>
希望本文所述對大家的PHP程序設計有所幫助。
