The following editor will bring you an article on the specific steps to install dblib extension in PHP and connect to mssql. The editor thinks it is quite good, so I will share it with you now and give it as a reference for everyone. Let’s follow the editor and take a look.
1. Install freetds first and then modify the configuration file.
Do not install version 0.82, otherwise it will report a compilation failure.
Compile Failure With freetds0.82
Go to the freetds directory to compile and install
./configure --prefix=/usr/local/freetds --enable-msdblib --enable-sybase-compat --disable-threadsafe make make install
2. Then install mssql
Go to the directory to compile and install
/usr/local/php/bin/phpize./configure --with-php-config=/usr/local/php/bin/php-config --with-mssql=/usr/local/freetds make make install
3. Install dblib
Go to the directory to compile and install
/usr/local/php/bin/phpize ./configure --with-php-config=/usr/local/php/bin/php-config --with-pdo-dblib=/usr/local/freetds make make install
4. Modify php.ini
extension=mssql.so extension=pdo_dblib.so
tsql client connection command
/usr/local/freetds/bin/tsql -H 192.168.1.100 -p 1433 -U sa -P 123456 -D user
Modify the configuration file
/usr/local/freetds/etc/freetds.conf 配置文件位置 tds version = 8.0 //修改 client charset = UTF8 //新增
If you cannot connect to the database, check the version and set tds version = 8.0 in the global option in /usr/local/freetds/etc/freetds.conf
If the result is garbled, change /usr/local/freetds/etc/freetds.conf and add a client charset = UTF8 to global
Adaptive Server is unavailable or does not exist ” error connecting to SQL Server from PHP It’s caused by not adding a port
You need to add a port or you can’t connect
'dblib:host=192.168.8.888:1433; dbname=xxxx'
The above are the specific steps for installing dblib extension in PHP and connecting to mssql. For more related content, please pay attention to the PHP Chinese website (www.php.cn)!

Load balancing affects session management, but can be resolved with session replication, session stickiness, and centralized session storage. 1. Session Replication Copy session data between servers. 2. Session stickiness directs user requests to the same server. 3. Centralized session storage uses independent servers such as Redis to store session data to ensure data sharing.

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching

Sessionhijacking refers to an attacker impersonating a user by obtaining the user's sessionID. Prevention methods include: 1) encrypting communication using HTTPS; 2) verifying the source of the sessionID; 3) using a secure sessionID generation algorithm; 4) regularly updating the sessionID.

The article discusses PHP, detailing its full form, main uses in web development, comparison with Python and Java, and its ease of learning for beginners.

PHP handles form data using $\_POST and $\_GET superglobals, with security ensured through validation, sanitization, and secure database interactions.

The article compares PHP and ASP.NET, focusing on their suitability for large-scale web applications, performance differences, and security features. Both are viable for large projects, but PHP is open-source and platform-independent, while ASP.NET,

PHP's case sensitivity varies: functions are insensitive, while variables and classes are sensitive. Best practices include consistent naming and using case-insensitive functions for comparisons.
