ANSI is a character code. In order to enable the computer to support more languages, 1 byte in the range of 0x00~0x7f is usually used to represent 1 English character. Anything outside this range is encoded using 0x80~0xFFFF, which is extended ASCII encoding.

In order for the computer to support more languages, 2 bytes in the range of 0x80~0xFFFF are usually used to represent 1 character. For example: the Chinese character '中' is stored in

ANSI encoding

ANSI encoding

Chinese operating system, using the two bytes [0xD6,0xD0] for storage.

Different countries and regions have formulated different standards, resulting in their own encoding standards such as GB2312, GBK, GB18030, Big5, and Shift_JIS. These various Chinese character extended encoding methods that use multiple bytes to represent a character are called ANSI encoding. In the Simplified Chinese Windows operating system, ANSI encoding represents GBK encoding; in the Traditional Chinese Windows operating system, ANSI encoding represents Big5; in the Japanese Windows operating system, ANSI encoding represents Shift_JIS encoding.

Different ANSI codes are incompatible with each other. When information is exchanged internationally, text belonging to two languages ??cannot be stored in the same ANSI coded text.

ANSI encoding uses one byte to represent English characters, and two or four bytes to represent Chinese characters.

how to convert a php array to xml

07 Jul 2025

To convert PHP arrays into XML, the core approach is to use recursive functions combined with SimpleXML extensions to process multi-dimensional arrays, and to select third-party libraries to simplify the process. 1. When using SimpleXML, recursively traverse array elements and build corresponding nodes. The number keys are converted to 'item' by default, and the value needs to be escaped with htmlspecialchars; 2. Third-party libraries such as thiagoalessio/xmlbuilder provide more intuitive chain calling methods, suitable for complex structures; 3. Notes include: numeric index processing, special character escape, hierarchical structure alignment and null value processing. The two methods have their own advantages and disadvantages, and they are chosen according to the project needs.

How do I use the GD library in PHP to resize, crop, and watermark images?

21 Jun 2025

PHP's GD library supports image processing operations without additional dependencies. 1. Resize: Use imagecreatefromjpeg() to load the picture, create a new size canvas, scale and save it through imagecopyresampled(); 2. Crop: After loading the original image, create a new target size canvas and copy the specified area; 3. Add a watermark: Use imagettftext() to add text or use imagecopy() to overlay the transparent PNG logo. The basic functions are simple and effective, and other libraries can be considered for complex needs.
