php錯誤500 ；End of script output before headers: index.php

以前能正常運行，今天切換php版本遇到下面的問題:

[Sun Apr 19 11:04:52.224694 2020] [core:notice] [pid 9164:tid 392] AH00094: Command line: 'E:\\WebSite\\PHP\\phpStudy2016\\Apache\\bin\\httpd.exe -d E:/WebSite/PHP/phpStudy2016/Apache'

參照：https://www.zhaokeli.com/article/8547.html 無效

參考：https://segmentfault.com/q/1010000014298584/a-1020000017977891

php.ini裏面註釋小對應插件，還是有問題：

切換其他版本php倒是能正常執行，應該是配置問題了

配置 php.ini
error_reporting = E_ALL
log_errors = On
error_log = php_errors.log

 

刷新頁面後打開php_errors.log：

[19-Apr-2020 11:52:04 Asia/Shanghai] PHP Warning:  Unknown: open_basedir restriction in effect. File(\www\app\index.php) is not within the allowed path(s): (C:/Windows/Temp/;C:/Temp/;E:/WebSite/PHP/temp/session/) in Unknown on line 0
[19-Apr-2020 11:52:04 Asia/Shanghai] PHP Warning:  Unknown: failed to open stream: Operation not permitted in Unknown on line 0

原來是不記得什麼時候配置了open_basedir，

這個是用來限制php的目錄訪問權限什麼的，如果不在允許的範圍內，php就不能訪問。

將其註釋掉即可。
