PHP mailparse.so 错误 - undefined symbol mbfl_convert_filter_flush

Question

sudo pecl install mailparse 结束于:

Build process completed successfully
Installing '/usr/lib64/php/5.5/modules/mailparse.so'
install ok: channel://pecl.php.net/mailparse-2.1.6
configuration option "php_ini" is not set to php.ini location
You should add "extension=mailparse.so" to php.ini

将extension=mailparse.so添加到php.ini的Dynamic Extensions部分后，运行php打印这个:

PHP 警告:PHP 启动:无法加载动态库 '/usr/lib64/php/5.5/modules/mailparse.so' -/usr/lib64/php/5.5/modules/mailparse.so: undefined symbol :第 0 行未知中的 mbfl_convert_filter_flush

Answer 1

解决方案

mailparse必须在mbstring之后加载，mbstring由/etc/php-5.5.d/mbstring加载。 ini 在php.ini之后读取。

仅仅将 mailparse.ini 添加到 php-5.5.d 是行不通的，因为 ini 文件是按字母顺序加载的；尽管您可以将其命名为 zz_mailparse.ini。

在仅(原文如此)php.ini 中加载两个扩展会导致:

PHP Warning:  Module 'mbstring' already loaded in Unknown on line 0
PHP Warning:  Module 'mailparse' already loaded in Unknown on line 0

那个是个谜。

证明

$ echo '<?php echo extension_loaded("mailparse") ? "mailparse loaded\n" : "mailparse not loaded\n";' > ~/is_mailparse_loaded.php
$ php ~/is_mailparse_loaded.php
mailparse loaded
$ pwd
/etc/php-5.5.d
$ sudo mv zz_mailparse.ini mailparse.ini
$ php ~/is_mailparse_loaded.php
PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib64/php/5.5/modules/mailparse.so' - /usr/lib64/php/5.5/modules/mailparse.so: undefined symbol: mbfl_convert_filter_flush in Unknown on line 0
mailparse not loaded
$ sudo mv mailparse.ini zz_mailparse.ini
