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

How does PHP handle object cloning (clone keyword) and the __clone magic method?How does PHP handle object cloning (clone keyword) and the __clone magic method?Apr 17, 2025 am 12:24 AM

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.
