Using MySQL databases in PHP, the efficiency of executing SQL statements directly affects application performance. Especially when dealing with large data operations and high concurrency scenarios, optimizing SQL execution has become a key focus for developers. This article will focus on the best practices for combining mysqli::options with mysqli::prepare.

In web development, preventing MIME type obfuscation attacks is an important part of improving website security. MIME type obfuscation attacks can cause browsers to misjudgment file types when processing files, causing potential security vulnerabilities. For example, a browser may process malicious files as images or text files, while the actual files contain malicious scripts.

In modern web development, ensuring the security of websites is an essential responsibility of developers. Browsers provide many mechanisms that enhance website security by setting specific HTTP headers, such as X-Frame-Options, X-Content-Type-Options, and Strict-Transport-Security. These headers help prevent attacks like clickjacking, MIME type sniffing, and cross-site scripting (XSS).

mysqli::debug() is a relatively useless but very powerful debugging tool in PHP. It allows developers to enable the debugging function of the underlying MySQLi extension, thereby analyzing details in connection, query execution, etc. After PHP 8.1, the parameter support of mysqli::debug() is more flexible, especially the trace options, which provide developers with stronger customization capabilities.

We often need to generate HTML elements from arrays. For example, generating an option list for the <select> drop-down box, usually using an array to dynamically fill the options of the drop-down box. The array_combine() function is a very practical tool that combines two arrays into an associative array to generate options for select drop-down boxes.
