PHP mailparse.so 错误 - 未定义符号 mbfl_convert_filter_flush

Question

sudo pecl install mailparse 以：

结尾

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 会打印以下内容：

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

Answer 1

解决方案

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

仅加载两个扩展（原文如此）php.ini 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
$ php ~/is_mailparse_loaded.php
mailparse loaded
$

Answer 2

快速单行：

sudo bash -c "echo 'extension=mailparse.so' >> /etc/php.d/zz_mailparse.ini"

编辑 - 有些安装在其他目录中，只需确保：

sudo bash -c "echo 'extension=mailparse.so' >> /etc/php-7.0.d/zz_mailparse.ini"
