这篇文章主要介绍了php批量添加数据与批量更新数据的实现方法,涉及针对表单的处理与sql语句的灵活使用,非常具有实用价值,需要的朋友可以参考下

本文实例讲述了php批量添加数据与批量更新数据的实现方法。分享给大家供大家参考。具体分析如下:

php如果要批量保存数据我们只要使用sql的insert into语句就可能实现数据批量保存了,如果是更新数据使用update set就可以完成更新了,操作方法都非常的简单,下面整理两个例子.

批量数据录入

设计方法:同时提交多条表单记录,为每一条记录设置相同的文本域名称,然后在表单处理页中,通过for循环来读取提取表单提交的数据,最后以数据的形式将数据逐条添加到数据库中.

其中,应用一个count()函数来获取数组中元素的个数.int count(mixed var);

表单提交页面,代码如下:

复制代码 代码如下:



商品名称
编号
单价
数量
产地


 







 



数据库连接页,代码如下:

复制代码 代码如下:

$id=mysql_connect("localhost","root","password") or die('connection failed'.mysql_error());
if(mysql_select_db('mydatabase',$id))
echo "";
else
echo('select db failed:'.mysql_error());
?>


表单处理页,代码如下:

复制代码 代码如下:

if($submit==true){
    for($i=0;$i         $path=$_POST["sp_name"][$i];
        $path1=$_POST["sp_number"][$i];
        $path2=$_POST["price"][$i];
        $path3=$_POST["counts"][$i];
        $path4=$_POST["address"][$i];
        $query=mysql_query("insert into tb_products(sp_name,sp_number,price,counts,address,data) values('$path','$path1','$path2','$path3','$path4','$data');}
    if($query==true){
        echo"提交成功";
    else
        echo"提交失败";}
}
?>


批量更新数据

主要通过while, list(),each()函数来实理数据的批量更新,list()函数用于一次性为多个变量赋值,代码如下:

复制代码 代码如下:



          $result=mysql_query($query);
             if($result==true){
             while($myrow=mysql_fetch_array($result)){
?>





表单处理页,代码如下:

复制代码 代码如下:

if($submit=="激活"){
    while(list($name,$value)=each($_POST)){
        $result=mysql_query("update tb_user set operation='激活' where");
    if($result==true){
        echo "<script> alert('激活成功');window.location.href='index.php';</script>";}}
 
if($submit2=="冻结"){
    while(list($name,$value)=each($_POST)){
        $result=mysql_query("update tb_user set operation='冻结' where");
    if($result==true){
        echo "<script> alert('冻结成功');window.location.href='index.php';</script>";}}
}
?>


总结:心细的朋友会发现两个例子都有几个共同点,一个是表单from的表单名是以counts[]数组形式了,而在php处理接受页面都会使用for 或while来实现遍历了,下面我就简单的给大家分析这两个例子.

counts[]:这个在表单中是代表数组,如果你有10个表单那么我们name=counts[] 意思他们内个都是一样数组,知道这个是数组了就知道下面知道为什么会使用遍历了.

for或while:因为表单过来的是数组我们就可以遍历数组然后对数据进行保存了,如下代码:

while(list($name,$value)=each($_POST)){ 或

for($i=0;$i

希望本文所述对大家的php程序设计有所帮助。

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
