另外一段代码是基于我这个数据库操作类的事务实例：
/*
注意，数据库操作表类型必须为InnoDB，其他类型不支持事务
PDO事务机制
$pdo->beginTransaction(); --开启事务
$pdo->commit(); --结束事务
$pdo->rollBack(); --回滚操作
示例，用try/catch包住db操作，当事务内的db操作出现中断，则执行回滚并抛出异常信息。
*/
try{
$pdo->beginTransaction();
hrInsert(0,1,"class","name,parentid","'god',0"); //可以正常执行
hrInsert(0,0,0,"tb_searchlog","userid,code","4"); //出错
$pdo->commit();
}catch(Exception $e){
$pdo->rollBack();
echo "Failed: " . $e->getMessage();
}
SET SQL_MODE="NO_AUTO_VALUE_ON_ZERO";

$sql = 'select distinct(ontopid),gb.id as id,f.id as fid,g.id as gid,g.*,gb.*,f.* from pk_groupbuy gb
left join pk_ontop as o on o.ontopid=gb.id

and gb.endtime>UNIX_TIMESTAMP() and gb.starttime<UNIX_TIMESTAMP()
group by onid limit $start,$num";
return TableSystem::query($sql);
变量说明：$arr_str是一个由pk_groupbuy中主键 id组成的一个数组，经过explode函数得到的字符串，
$start,$num分别是查询的开始记录数，和要查询的记录数。
问题说明：pk_ontop表中ontopid在不能记录中有重复现象
比如：我只需要查询出来pk_ontop中当天置顶的ontopid，即商品id，不需要其他的商品信息，查询出来的有ontopid就算有重复现象，这时我可以通过去除数组重复元素解决问题，但是如果我要查询出相应商品id并查询其他相关联表中的信息，并按照ontop表中starttime，status，paixu字段进行排序等操作时，就需要join pk_ontop表，所以之前解决的重复问题就又会出现，无法处理，特别是在api中，是不允许出现重复的，这要怎么办呢？我也不会额，别人教我这样弄，请大家参考下：

今天把在php教程开发中常用到的数据库教程操作方法函数总结分析一下了，希望有兴趣的朋友可以参考一下。
一、数据库操作
1. 连接MYSQL数据
mysql教程_connect()
提示和注释
注释：脚本一结束，到服务器的连接就被关闭，除非之前已经明确调用 mysql_close() 关闭了。
提示：要创建一个持久连接，请使用 mysql_pconnect() 函数。
例子
<?php
$con = mysql_connect("localhost","mysql_user","mysql_pwd");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}// 一些代码...
mysql_close($con);
?>
e.g.
$db = mysql_connect(MYSQL_HOST, MYSQL_USER, MYSQL_PASSWORD) or die(‘ www.111cn.net Unable to connect, please check connection paremeters’);
2. 选择数据库
mysql_select_db()
连接上数据库后，PHP默认选择的数据库未必是我们后面操作中需要的数据库，为确保数据库选择正确，一般在数据库连接语句后面还要加上数据库选择语句。
mysql_select_db() 函数设置活动的 MySQL 数据库。
如果成功，则该函数返回 true。如果失败，则返回 false。
语法
mysql_select_db(database,connection)
参数 描述
database 必需。规定要选择的数据库。
connection 可选。规定 MySQL 连接。如果未指定，则使用上一个连接。
e.g.
mysql_select_db(MYSQL_DB, $db) or die(mysql_error($db));
3. 执行SQL语句
mysql_query()
该函数将SQL语句发送到当前活动的数据库并执行语句，返回结果。
定义和用法
mysql_query() 函数执行一条 MySQL 查询。
语法
mysql_query(query,connection)
参数 描述
query 必需。规定要发送的 SQL 查询。注释：查询字符串不应以分号结束。
connection 可选。规定 SQL 连接标识符。如果未规定，则使用上一个打开的连接。
说明
如果没有打开的连接，本函数会尝试无参数调用 mysql_connect() 函数来建立一个连接并使用之。
返回值
mysql_query() 仅对 SELECT，SHOW，EXPLAIN 或 DESCRIBE 语句返回一个资源标识符，如果查询执行不正确则返回 FALSE。
对于其它类型的 SQL 语句，mysql_query() 在执行成功时返回 TRUE，出错时返回 FALSE。
非 FALSE 的返回值意味着查询是合法的并能够被服务器执行。这并不说明任何有关影响到的或返回的行数。很有可能一条查询执行成功了但并未影响到或并未返回任何行。
e.g.
$query = “SELECT * FROM $table”
$result = mysql_query($query, $db) or die(mysql_error($db));
4. 关闭数据库
mysql_close()
该函数用于关闭不需要继续活跃的数据库，但该方法不是必须的，一般PHP会自动关闭不继续活跃的数据库。
e.g.
mysql_close($db);
5. 释放SQL结果
mysql_free_result()
该函数用于释放mysql_query()执行结果占用的内存，该函数很少被调用，除非result很大，占用太多内存；一般在PHP脚本执行结束之后很自动释放占用的内存。
e.g
ysql_free_result() 函数释放结果内存。
如果成功，则返回 true，如果失败，则返回 false。
语法
mysql_free_result(data)
参数 描述
data 必需。要释放的结果标识符。该结果标识符是从 mysql_query() 返回的结果。
提示和注释
注释：mysql_free_result() 仅需要在考虑到返回很大的结果集时会占用多少内存时调用。在脚本结束后所有关联的内存都会被自动释放。
例子
<?php
$con = mysql_connect("localhost", "peter", "abc123");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}$db_selected = mysql_select_db("test_db",$con);
$sql = "SELECT * from Person";
$result = mysql_query($sql,$con);
print_r(mysql_fetch_row($result));// 释放内存
mysql_free_result($result);
$sql = "SELECT * from Customers";
$result = mysql_query($sql,$con);
print_r(mysql_fetch_row($result));mysql_close($con);
?>
二、SQL执行结果操作
1. 返回执行结果中的一行
mysql_fetch_row()
返回执行结果的当前行的数值数组，执行这个函数后，结果指向下一行。
e.g.
$row = mysql_fetch_row($result);
处理执行结果一般放在while循环中，遍历每一行
e.g.
while($row = mysql_fetch_row($result))
{……}
2. mysql_fetch_row()的替代方法
mysql_fetch_array()
mysql_fetch_assoc()
mysql_fetch_array()返回键值对数组，键为查询的table的列名；
mysql_fetch_assoc()返回结果时可以先排序（如果为可选参数赋值），相当于mysql_fetch_array()+MYSQL_ASSOC
3. 执行结果的字段（列）属性
mysql_fetch_field()
eg.
mysql_fetch_field() 函数从结果集中取得列信息并作为对象返回。
mysql_fetch_field() 可以用来从查询结果中取得字段的信息。如果没有指定字段偏移量，则提取下一个尚未被 mysql_fetch_field() 取得的字段。
该函数返回一个包含字段信息的对象。
被返回的对象的属性为：
name - 列名
table - 该列所在的表名
max_length - 该列最大长度
not_null - 1，如果该列不能为 NULL
primary_key - 1，如果该列是 primary key
unique_key - 1，如果该列是 unique key
multiple_key - 1，如果该列是 non-unique key
numeric - 1，如果该列是 numeric
blob - 1，如果该列是 BLOB
type - 该列的类型
unsigned - 1，如果该列是无符号数
zerofill - 1，如果该列是 zero-filled
语法
mysql_fetch_field(data,field_offset)
参数 描述
data 必需。要使用的数据指针。该数据指针是从 mysql_query() 返回的结果。
field_offset 必需。规定从哪个字段开始。0 指示第一个字段。如果未设置，则取回下一个字段。
提示和注释
注释：本函数返回的字段名是区分大小写的。
例子
<?php
$con = mysql_connect("localhost", "hello", "321");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}$db_selected = mysql_select_db("test_db",$con);
$sql = "SELECT * from Person";
$result = mysql_query($sql,$con);while ($property = mysql_fetch_field($result))
{
echo "Field name: " . $property->name . "<br />";
echo "Table name: " . $property->table . "<br />";
echo "Default value: " . $property->def . "<br />";
echo "Max length: " . $property->max_length . "<br />";
echo "Not NULL: " . $property->not_null . "<br />";
echo "Primary Key: " . $property->primary_key . "<br />";
echo "Unique Key: " . $property->unique_key . "<br />";
echo "Mutliple Key: " . $property->multiple_key . "<br />";
echo "Numeric Field: " . $property->numeric . "<br />";
echo "BLOB: " . $property->blob . "<br />";
echo "Field Type: " . $property->type . "<br />";
echo "Unsigned: " . $property->unsigned . "<br />";
echo "Zero-filled: " . $property->zerofill . "<br /><br />";
}mysql_close($con);
?>
4. 查询数据库中的表名
我们要显示所有的表就会用到mysql_list_tables用法语法来操作，
mysql_list_tables 语法
mysql_list_tables()
e.g.
$db_name = MYSQL_DB;
$result = mysql_list_tables($db_name);
echo “数据库中包含如下表：”;
while ($row = mysql_fetch_row($result))
{
echo $row[0];
}
5. 查询数据库的列名（字段名）
esource mysql_list_fields ( string database_name, string table_name [, resource link_identifier] )
mysql_list_fields() 取得给定表名的信息。参数是数据库名和表名。返回一个结果指针，可以用于 mysql_field_flags()，mysql_field_len()，mysql_field_name() 和 mysql_field_ty
mysql_list_fields()
e.g.
$fields = mysql_list_fields($db_name,$table);
$columns = mysql_num_fields($fields);
for ($i = 0; $i < $columns; $i++)
echo mysql_field_name($fields, $i);
三、其他函数
1. mysql_num_rows()
mysql_num_rows() 函数返回结果集中行的数目。
语法
mysql_num_rows(data)
参数 描述
data 必需。结果集。该结果集从 mysql_query() 的调用中得到。
说明
mysql_num_rows() 返回结果集中行的数目。此命令仅对 SELECT 语句有效。要取得被 INSERT，UPDATE 或者 DELETE 查询所影响到的行的数目，用 mysql_affected_rows()。
返回执行结果的行数。
e.g.
$num = mysql_num_rows($result);
2. mysql_num_fields()
返回执行结果的列数（字段数）。
e.g. $num = mysql_num_fields($result);
3.mysql_set_charset()
设置执行结果的编码，防止在网页中显示中文时乱码。
e.g.
$query = “select * from $table_name”;
mysql_query(‘set names utf8′);
$result = mysql_query($query, $db) or die(mysql_error($db));
注：
1. 文中大写代码为预定义的内容，如define(MYSQL_HOST, ‘localhost’);
