Differences between PHPiconv and mb_convert_encoding

PHPiconv and mb_convert_encoding differences PHP often uses the iconv function in character transcoding, but encountered a problem in a transcoding; example: $ str Today weather-fine; $ striconv (UTF-8, GBK, $ str,); after transcoding, $ str is clear only today. find the manual and find that the second parameter of iconv can be added to the differences between iconv and mb_convert_encoding of PHP.

PHP often uses the iconv function in character transcoding, but encountered a problem in a certain transcoding;

Example:

$ Str = 'weather today-Clear ';

$ Str = iconv ('utf-8', 'gbk', $ str ,);

After transcoding, $ str is only 'Weather is fine today '. find the manual and find that two suffixes can be added to the second parameter of iconv,

?

? // Transcoder automatically converts a character that cannot be directly converted into one or more similar characters,

? // IGNORE ignores the characters that cannot be converted. by default, it is truncated from the first invalid character.

?

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. In any case, the "-" cannot be converted successfully or 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 than iconv;

3. 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 displayed normally after conversion.

Note: To use mb_convert_encoding, you need to enable this extension in php. ini.
