我已经阅读了大量的文章，指出mailparse需要在mbstring之后加载，但是，即使在用zz加前缀mailparse的时候，它仍然存在相同的问题，我真的很想知道为什么。
虽然我仍然在模块列表中看到它。
[root@intranet:~]# php -m PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/zz-mailparse.so' - /usr/lib64/php/modules/zz- mailparse.so: undefined symbol: mbfl_convert_filter_flush in Unknown on line 0 [PHP Modules] bz2 calendar Core ctype curl date dom ereg exif fileinfo filter ftp gd gettext gmp hash iconv imap intl json libxml mailparse mbstring mcrypt mhash mysql mysqli openssl pcntl pcre PDO pdo_mysql pdo_sqlite Phar readline Reflection session shmop SimpleXML sockets SPL sqlite3 standard tokenizer wddx xml xmlreader xmlwriter xsl Zend OPcache zip zlib [Zend Modules] Zend OPcache 在/etc/php.ini
extension=zz-mailparse.so
不知道是否这是问题，即使我有SSELinux作为宽容。
