php批量添加数据与批量更新数据的实现方法,php添加数据
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:
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
$path1=$_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:
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)){
$result=mysql_query("update tb_user set operation='激活' where id='".$name."'");
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)){
$result=mysql_query("update tb_user set operation='冻结' where id='".$name."'");
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。

MySQL and phpMyAdmin can be effectively managed through the following steps: 1. Create and delete database: Just click in phpMyAdmin to complete. 2. Manage tables: You can create tables, modify structures, and add indexes. 3. Data operation: Supports inserting, updating, deleting data and executing SQL queries. 4. Import and export data: Supports SQL, CSV, XML and other formats. 5. Optimization and monitoring: Use the OPTIMIZETABLE command to optimize tables and use query analyzers and monitoring tools to solve performance problems.

AI can help optimize the use of Composer. Specific methods include: 1. Dependency management optimization: AI analyzes dependencies, recommends the best version combination, and reduces conflicts. 2. Automated code generation: AI generates composer.json files that conform to best practices. 3. Improve code quality: AI detects potential problems, provides optimization suggestions, and improves code quality. These methods are implemented through machine learning and natural language processing technologies to help developers improve efficiency and code quality.

In MySQL, add fields using ALTERTABLEtable_nameADDCOLUMNnew_columnVARCHAR(255)AFTERexisting_column, delete fields using ALTERTABLEtable_nameDROPCOLUMNcolumn_to_drop. When adding fields, you need to specify a location to optimize query performance and data structure; before deleting fields, you need to confirm that the operation is irreversible; modifying table structure using online DDL, backup data, test environment, and low-load time periods is performance optimization and best practice.

To safely and thoroughly uninstall MySQL and clean all residual files, follow the following steps: 1. Stop MySQL service; 2. Uninstall MySQL packages; 3. Clean configuration files and data directories; 4. Verify that the uninstallation is thorough.

Efficient methods for batch inserting data in MySQL include: 1. Using INSERTINTO...VALUES syntax, 2. Using LOADDATAINFILE command, 3. Using transaction processing, 4. Adjust batch size, 5. Disable indexing, 6. Using INSERTIGNORE or INSERT...ONDUPLICATEKEYUPDATE, these methods can significantly improve database operation efficiency.

MySQL functions can be used for data processing and calculation. 1. Basic usage includes string processing, date calculation and mathematical operations. 2. Advanced usage involves combining multiple functions to implement complex operations. 3. Performance optimization requires avoiding the use of functions in the WHERE clause and using GROUPBY and temporary tables.

Installing MySQL on macOS can be achieved through the following steps: 1. Install Homebrew, using the command /bin/bash-c"$(curl-fsSLhttps://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)". 2. Update Homebrew and use brewupdate. 3. Install MySQL and use brewinstallmysql. 4. Start MySQL service and use brewservicesstartmysql. After installation, you can use mysql-u
