xampp - apache http server 经常对php请求返回空白页?
我在windows机器上安装的是xampp的系统,在本地用apache做 web server,用php写server side, 一直以来都是正常运行。
最近的一个project,用到ssl, zend framework, jquery 之类,经常性的但是是随机不可重复的,提交请求一个Php网页时,web server返回空白页,我检查了http的respond,状态代码是200,应该是正常的,可是为什么返回内容为空呢?
有时候刷新好几下,这个空白页才变成了正常的网页。
我有检查log文件,好像没什么http请求错误或是php的错误。
请教牛人们, 这可能是什么原因造成的? 或者,我需要从哪些地方入手去debug?

症状来看高度疑似 PHP 错误.查看 phpinfo() 输出内容,检查 php.ini 文件路径,打开 php.ini ,修改错误相关的设置.
<code>display_errors = On error_reporting = E_ALL </code>
设置为这样可以看到原来空白页里 PHP 的报错内容
如果无法复现空白页,将 php.ini 中
<code>log_errors = On error_log = /path/to/error.log </code>
注意 PHP进程要有 error.log 的写权限. 不定时查看该文件就可以看到 PHP 的报错.
