Example of character encoding conversion function usage in PHP, php example In this paper, the use of the character encoding conversion function in PHP is described and shared for everyone's reference. The implementation method is as follows: In general, in the Web program, especially when it comes to the reading process of the database, the most annoying is the problem of character encoding, php4.0.6 the version above provides mb_convert_encoding can be easily converted code.

failure. Usage: 1. It is found that iconv will encounter an error when converting the character "-" To gb2312. If the ignore parameter is not available, all strings after this character cannot be saved. Either way, this "-" Cannot be converted successfully, and cannot be output. In addition, mb_convert_encoding does not have this bug. 2. mb_convert_encoding can specify multiple input encodings, which are automatically identified based on the content, but the execution efficiency is much lower

This article describes how to solve the problem of truncation characters during iconv function transcoding in PHP. the solution provided in this article is to use mb_convert_encoding instead of iconv, if you need iconv, refer to iconv conversion encoding. However, the iconv is not fully displayed during Chinese transcoding. The code is as follows: Iconv ("UTF-8", "GB2312 // IGNORE", $ data); with // IGNORE, IGNORE errors Or use mb_convert_encoding () The code is as follows: /* Con

bug.2. mb_convert_encoding can specify multiple input encodings, which are automatically identified based on the content, but the execution efficiency is much lower than that of iconv. for example: $ str = mb_convert_encoding ($ str, "euc-jp ", "ascii, jis, euc-jp, sjis, utf-8"); the order of "ascii, jis, euc-jp, sjis, UTF-8" varies with the effect.3. generally,

Php code conversion function. Generally, iconv is used. the mb_convert_encoding function is used only when the encoding of the original encoding cannot be determined or The iconv cannot be normally displayed after conversion. Iconv function syntax: generally, iconv is used. the mb_convert_encoding function is used only when the encoding of the original encoding cannot be determined or cannot be properly displayed after iconv conversion. Iconv function syntax: echo iconv("ISO-8859-1", "UTF-8"
