php连接sql server的三种方法小结
参考php手册,对php连接sql server系列做出个小结。主要有三种方式:
一、通过mssql_系列函数,主要针对php5.3以下的版本和sqlserver2000及以上版本使用。在php.ini中将;extension=php_mssql.dll;extension=php_msql.dll;extension=php_pdo_mssql.dll ;extension=php_pdo_odbc.dll 前面的分号去掉。
二、通过sqlsrv_系列函数,主要针对php5.3以上的版本和sql server 2005以上版本使用。需要下载安装Microsoft Drivers for PHP for SQL Server驱动,地址:https://msdn.microsoft.com/library/dn865013.aspx。下载后解压放到php对应的ext目录下。然后打开php.ini文件,在extension 后面添加一下配置
extension=php_pdo_sqlsrv_53_ts.dll
extension=php_sqlsrv_53_ts.dll
重启apache,查看phpinfo(),确保apache已经支持sqlsrv。如下图所示:
并且安装sqlncli.msi,这个文件是协助windows环境访问sql server所在的数据库服务器的
三、通过odbc方式连接sqlserver系列。需要在php.ini中开启odbc系列扩展。在phpinfo函数中看到
下面是实现代码:
// $serverName = "localhost";
// $connectionInfo = array( "Database"=>"JXC_ERP", "UID"=>"sa", "PWD"=>"123456");
// $conn = sqlsrv_connect( $serverName, $connectionInfo );
// if( $conn === false ) {
// die( print_r( sqlsrv_errors(), true));
// }
// $sql = "SELECT * FROM dbo.A_PHP";
// $stmt = sqlsrv_query( $conn, $sql );
// if( $stmt === false) {
// die( print_r( sqlsrv_errors(), true) );
// }
// while($row = sqlsrv_fetch_array($stmt))
// {echo $row[0]."-----".$row[1]."
";}
$con = odbc_connect('JXC_ERP','sa','123456');
$query = "SELECT * FROM dbo.A_PHP";
$result = odbc_do($con,$query);
while(odbc_fetch_row($result))
{
$list = odbc_result($result, "id"); print_r($list);echo '
';
}
// $server ="localhost"; //服务器IP地址,如果是本地,可以写成localhost
// $uid ="sa"; //用户名
// $pwd ="123456"; //密码
// $database ="JXC_ERP"; //数据库名称
////进行数据库连接
// $conn =mssql_connect($server,$uid,$pwd) or die ("connect failed");
// mssql_select_db($database,$conn);
////执行查询语句
// $query ="select * from A_PHP";
// $row =mssql_query($query);
////打印输出查询结果
// while($list=mssql_fetch_array($row))
// {
// print_r($list);
// echo "
";
// }
?>

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.
