上面的 word 怎样拼凑才能优雅些?
回复内容:
<code>$username = $this->username ?: 'someone'; $email = $this->email ?: Yii::$app->params['adminEmail']; $password = Yii::$app->getSecurity()->generatePasswordHash( $this->password ?: 'xx' ); $table = User::tableName(); $auth_key = Yii::$app->security->generateRandomString(); $status = User::STATUS_ACTIVE; $timestamp = time(); $god = 1; $words = "in the ${table} has a record which contains some value : "; $words .= "'${username}', '${email}', '${password}', '${auth_key}', '${status}','${timestamp}', '${god}', '${timestamp}', '${god}' "; </code>

sprintf
是个不错的方案
不过看你的代码感觉就是像把各种变量都打出来调试用,那么有个神器 get_defined_vars
,变量名变量值都有了你值得拥有
一句话,尽量使用 ORM 或者 数据库类 去操作数据库,而不要人工拼凑字符串,这样能有效防止 SQL注入 的发生。Yii 框架肯定是自带这些东西的,你上文档好好看看就好啦:http://www.yiiframework.com/doc/guide/1.1/en/database.dao#binding-para...
如果是单纯的拼接字符串的话一般情况下双引号内直接写变量名(不用花括号)就可以了,当然介于那个字段的拼接实在是有点丑你可以这么改写一下:
<code>$words = "in the $table has a record which contains some value: "; $words .= implode(", ", array_map(function($item) { return "'$item'"; }, [$username, $email, $password, $auth_key, $status, $timestamp, $god]) ); </code>
存数组遍历呗

Arrays can be stored in PHP sessions. 1. Start the session and use session_start(). 2. Create an array and store it in $_SESSION. 3. Retrieve the array through $_SESSION. 4. Optimize session data to improve performance.

PHP session garbage collection is triggered through a probability mechanism to clean up expired session data. 1) Set the trigger probability and session life cycle in the configuration file; 2) You can use cron tasks to optimize high-load applications; 3) You need to balance the garbage collection frequency and performance to avoid data loss.

Tracking user session activities in PHP is implemented through session management. 1) Use session_start() to start the session. 2) Store and access data through the $_SESSION array. 3) Call session_destroy() to end the session. Session tracking is used for user behavior analysis, security monitoring, and performance optimization.

Using databases to store PHP session data can improve performance and scalability. 1) Configure MySQL to store session data: Set up the session processor in php.ini or PHP code. 2) Implement custom session processor: define open, close, read, write and other functions to interact with the database. 3) Optimization and best practices: Use indexing, caching, data compression and distributed storage to improve performance.

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

The session realizes user authentication through the server-side state management mechanism. 1) Session creation and generation of unique IDs, 2) IDs are passed through cookies, 3) Server stores and accesses session data through IDs, 4) User authentication and status management are realized, improving application security and user experience.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
