PHP通过两种方式进行扩展应用

1.通过 .so进行配置

文件写在/usr/lib/2015XXX/，包含动态库文件。

2.通过 .dll进行配置

PHP越大越容易被弃用，在各种/etc/的php.ini中，去掉 “;” 代表使用dll文件。

这两种方法的目的都是为了引用库。

Apache2中PHP 7会和Flask的wsgi冲突

现象

在flask.py下可以正常调用mongodb数据库，在apache2会报错：

Segmentation Faults and “Truncated or oversized response headers received from daemon process”

经 https://github.com/GrahamDumpleton/mod_wsgi/issues/351 发现，PHP与flask会存在冲突，当php关闭后WSGI可以正常使用。

  1. a2dismod php7.0 (apache2关闭模块命令)

其中有可能是214模块过多的问题：

  1. php -m (查看模块)

补一个guolab方面的应用：和202相比就多一个xdebug。

php禁用多余模块

  1. phpenmod–用于在php中启用模块
  2. phpdismod–用于禁用php中的模块
  3. phpquery–用于查看php模块的状态

可能会起到效果，需要重启验证。

PHP常见问题

1.如果卸载的是mod等文件，系统会报错，需要通过重启解决。

问题安装由来
