PDO prepare 简介

使用预处理语句——prepare()方法

1、使用命名参数

$pdo = new PDO($dsn,$user,$pwd); 
$sql = ‘insert into table1 set name=:name,age=:age‘; 
$result = $pdo->prepare($sql); 
//执行准备sql 
$result->excute(array(‘:name‘=>‘zhangsan‘,‘:age‘=>‘2‘)); 

2、使用问号参数

$pdo = new PDO($dsn,$user,$pwd); 
$sql = "insert into table1 set name=?,age=?"; 
$result = $pdo->prepare($sql); 
//执行准备sql 
$name = ‘zhangsan‘;$age = ‘2‘; 
$result->excute(array($name,$age)); 

3、通过bindParam()方法

$pdo = new PDO($dsn,$user,$pwd); 
$sql = ‘insert into table1 set name=:name,age=:age‘; 
$result = $pdo->prepare($sql); 
//绑定参数 
$name = ‘zhangsan‘;$age = ‘2‘; 
$result->bindParam(‘:name‘=>$name); 
$result->bindParam(‘:age‘=>$age); 
//执行准备sql 
$result->excute();
