本文实例讲述了thinkphp配置连接数据库的常用方法,分享给大家供大家参考。具体方法如下:
1.在thinkphp入口文件同目录下的config.inc.php中添加数据库配置信息
代码如下:
return array(
'DB_TYPE'=>'mysqli',
'DB_HOST'=>'localhost',
'DB_NAME'=>'demo',
'DB_USER'=>'root',
'DB_PWD'=>'root',
'DB_PREFIX'=>'think_',
);
?>
然后在项目目录的config.php文件中添加如下代码:
代码如下:
$arr1=array(
//'配置项'=>'配置值'
'URL_MODEL'=>2,
'APP_DEBUG'=>true,
'LOG_RECORD'=>true,
......
);
$arr2=include 'config.inc.php';
return array_merge($arr1,$arr2);
?>
在后台文件中也可以添加如上代码,这样在数据库配置的连接信息改动后,只需要修改config.inc.php文件中的信息就可以达到同时修改前台与后台的数据库连接配置信息。
2. 如果在控制器中要连接另外的数据库可以通过添加如下代码完成:
代码如下:
$arrr=array(
'dbms'=>'mysqli', //注意本书组中键名是规定的不能变动.
'username'=>'google',
'password'=>'hello',
'hostname'=>'127.0.0.1',
'database'=>'MYDBname',
);
$db=new Db($arrr);
希望本文所述对大家的ThinkPHP框架程序设计有所帮助。

Calculating the total number of elements in a PHP multidimensional array can be done using recursive or iterative methods. 1. The recursive method counts by traversing the array and recursively processing nested arrays. 2. The iterative method uses the stack to simulate recursion to avoid depth problems. 3. The array_walk_recursive function can also be implemented, but it requires manual counting.

In PHP, the characteristic of a do-while loop is to ensure that the loop body is executed at least once, and then decide whether to continue the loop based on the conditions. 1) It executes the loop body before conditional checking, suitable for scenarios where operations need to be performed at least once, such as user input verification and menu systems. 2) However, the syntax of the do-while loop can cause confusion among newbies and may add unnecessary performance overhead.

Efficient hashing strings in PHP can use the following methods: 1. Use the md5 function for fast hashing, but is not suitable for password storage. 2. Use the sha256 function to improve security. 3. Use the password_hash function to process passwords to provide the highest security and convenience.

Implementing an array sliding window in PHP can be done by functions slideWindow and slideWindowAverage. 1. Use the slideWindow function to split an array into a fixed-size subarray. 2. Use the slideWindowAverage function to calculate the average value in each window. 3. For real-time data streams, asynchronous processing and outlier detection can be used using ReactPHP.

The __clone method in PHP is used to perform custom operations when object cloning. When cloning an object using the clone keyword, if the object has a __clone method, the method will be automatically called, allowing customized processing during the cloning process, such as resetting the reference type attribute to ensure the independence of the cloned object.

In PHP, goto statements are used to unconditionally jump to specific tags in the program. 1) It can simplify the processing of complex nested loops or conditional statements, but 2) Using goto may make the code difficult to understand and maintain, and 3) It is recommended to give priority to the use of structured control statements. Overall, goto should be used with caution and best practices are followed to ensure the readability and maintainability of the code.

In PHP, data statistics can be achieved by using built-in functions, custom functions, and third-party libraries. 1) Use built-in functions such as array_sum() and count() to perform basic statistics. 2) Write custom functions to calculate complex statistics such as medians. 3) Use the PHP-ML library to perform advanced statistical analysis. Through these methods, data statistics can be performed efficiently.

Yes, anonymous functions in PHP refer to functions without names. They can be passed as parameters to other functions and as return values of functions, making the code more flexible and efficient. When using anonymous functions, you need to pay attention to scope and performance issues.
