mysql_field_type

(PHP 3, PHP 4, PHP 5)

mysql_field_type --  取得结果集中指定字段的类型

说明

string mysql_field_type ( resource result, int field_offset )

mysql_field_type()mysql_field_name() 函数相似。参数完全相同,但返回的是字段类型而不是字段名。字段类型有“int”,“real”,“string”,“blob”以及其它,详见 MySQL 手册

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();
?>

以上例子将产生如下输出:

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

为向下兼容仍然可以使用 mysql_fieldtype(),但反对这样做。
