HomeDatabaseMysql TutorialFatal error: Class ‘mysqli’ not found in解决办法

昨天把数据库重新安装了一下结果就提示Fatal error: Class ‘mysqli’ not found in这个功能了,下面我来大家分享的我解决办法。

在windows中服务器解决办法很简单

解决方法

在php.ini里面去掉

 代码如下 复制代码

extension=php_mysqli.dll

这一行前面的分号";",然后再重启IIS/Apache,就可以了,如果还是不行我们可以把php目录中的php_mysqli.dll把这个文件拷到system32目录下,另外开启mysqli扩展,即把php.ini里的;extension=php_mysqli.dll前面的分号去掉,重启服务,应该就有了。

然后再再重启IIS/Apache

在linux中解决办法稍加复杂一点,因为都是命令模式了

 代码如下 复制代码


cd php-5.2.8 //在这下面有个ext文件夹里有mysqli
cd ext/mysqli

linux下将源码文件编译应该都有configure吧,可这里没有,在我们已经安装php后,php5这个文件夹里的命令目录bin里有一个文件叫phpize,用它就可以生成configure文件啦,继续

 代码如下 复制代码

/usr/local/php5/bin/phpize //这里回车运行,执行完后就出了configure文件,
./configure –prefix=/usr/local/mysqli –with-php-config=/usr/local/php5/bin/php-config –with-mysqli=/usr/local/mysql/bin/mysql_config

直接回车,不出问题就继续。。

 代码如下 复制代码

make
make test
make install //(不出错就会显示Installing shared extensions: /usr/local/php5/lib/php/extensions/no-debug-non-zts-20041030/)

现在mysqli.so文件就出来啦。。

直接在php.ini里把这个文件加载就OK啦。。

 代码如下 复制代码

extension_dir=”/usr/local/php5/ext”
extension=mysqli.so

把上面第一行找到修改成这个,然后再把第二行加入。。wq保存退出。

把mysqli.so这个文件cp到/usr/local/php5/ext下

The situations when choosing InnoDB instead of MyISAM include: 1) transaction support, 2) high concurrency environment, 3) high data consistency; conversely, the situation when choosing MyISAM includes: 1) mainly read operations, 2) no transaction support is required. InnoDB is suitable for applications that require high data consistency and transaction processing, such as e-commerce platforms, while MyISAM is suitable for read-intensive and transaction-free applications such as blog systems.

Indexes in MySQL are an ordered structure of one or more columns in a database table, used to speed up data retrieval. 1) Indexes improve query speed by reducing the amount of scanned data. 2) B-Tree index uses a balanced tree structure, which is suitable for range query and sorting. 3) Use CREATEINDEX statements to create indexes, such as CREATEINDEXidx_customer_idONorders(customer_id). 4) Composite indexes can optimize multi-column queries, such as CREATEINDEXidx_customer_orderONorders(customer_id,order_date). 5) Use EXPLAIN to analyze query plans and avoid

Using transactions in MySQL ensures data consistency. 1) Start the transaction through STARTTRANSACTION, and then execute SQL operations and submit it with COMMIT or ROLLBACK. 2) Use SAVEPOINT to set a save point to allow partial rollback. 3) Performance optimization suggestions include shortening transaction time, avoiding large-scale queries and using isolation levels reasonably.
