function array_iconv($in_charset,$out_charset,$arr){ return eval('return '.iconv($in_charset,$out_charset,var_export($arr,true).';')); }Copy code principle analysis : var_export sets the second parameter to true, returns the array prototype string, converts the string to utf-8 encoding, and then uses eval to perform the return (similar to an anonymous function?), which perfectly solves the problem. Subsequent: The method found online is mostly the method of calling iconv recursively. If the array elements are too large or the number of dimensions is more, the performance is definitely not good. The array is still associated with an array, and everything has been automatically completed, ensuring that the data before and after the array conversion is consistent. In terms of the length of the code and the comparison of the cycle and native methods, the method of this article is good.

## :: PHP number array encoding conversion Due to the display effect of some special characters, the UTF-8 project of the habit has been changed to GBK. Because AJAX technology is used, it also involves old problems -coding conversion. Some form verification needs to return JSON data. The json_encode function of the php only supports UTF-8 coding. Helpless ICONV is helpless. The effect that needs to be achieved is that the GBK array is converted to the UTF-8 array and passed to the json_encode function. The initial idea is to

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.
