Iconv transcoding failed on the UTF-8 encoding page in php

When iconv encounters a character that cannot be transcoded, the interrupted content is lost. the code is as follows: $ c & amp; lsquo; test & amp; bull; character transfer & amp; bull; Happy May Day! & Amp; rsquo; echoiconv (& amp; lsquo; UTF-8 & amp; prim

Iconv is interrupted when transcoding fails. the code is as follows:

1. $ C = 'Test • character transfer • Happy May Day! ';
2. Echo iconv ('utf-8', 'gbk', $ c );

Only output: After the test, the plenary session is lost.

Solution:Add // IGNORE, the code is as follows:

1. $ C = 'Test • character transfer • Happy May Day! ';
2. Echo iconv ('utf-8', 'gbk // IGNORE ', $ c );

Input: test character transfer for Happy May Day! Ignore indicates that the conversion error is ignored. without the ignore parameter, all strings after this character cannot be saved.
