问题
I have been trying to import/include file in my php script file and somehow it is not working. I know this require_once question has been asked so many times [ 1. require_once with subfolders , 2. require_once() cant find the include path, 3. Using require_once for up directory not working] but none of them seemed to be working for me.
Blow picture will explain what I am trying to do clearly:
What I tried and errors:
Attempt 1
require_once(__DIR__.'GoogleClientApi/src/Google/Service/Analytics.php');
echo 'Hey1'; //Does not echo this, means something went wrong above.
require_once(__DIR__.'GoogleClientApi/src/Google/Client.php');
echo 'Hey2';
Error I get:
Attempt 2 (Fixed issue of attempt 1 but raised another issue.)
So I decided to use absolute path :
include '/Applications/MAMP/htdocs/GoogleClientApi/src/Google/Client.php';
echo 'Hey1';
include '/Applications/MAMP/htdocs/GoogleClientApi/src/Google/Service/Analytics.php';
echo 'Hey2';
Gives me error in Client.php file:
`Warning: require_once(/Google/Auth/AssertionCredentials.php): failed to open stream: No such file or directory in /Applications/MAMP/htdocs/GoogleClientApi/src/Google/Client.php on line 18`
`Fatal error: require_once(): Failed opening required '/Google/Auth/AssertionCredentials.php' (include_path='.:/Applications/MAMP/bin/php/php5.5.10/lib/php') in /Applications/MAMP/htdocs/GoogleClientApi/src/Google/Client.php on line 18`
Investigating upon I found Client.php (of Google APIs Client Library for PHP) has these lines which are actually present:
require_once 'Google/Auth/AssertionCredentials.php'; // <-- Can't find
require_once 'Google/Cache/File.php'; // <-- Can't find
require_once 'Google/Cache/Memcache.php'; // <-- Can't find
I do not what is going wrong here. Fixed attempt 1's issue but now errors are in google's own library which I do not know how to overcome. I assume I am doing something silly which I can not figure out. Any help or suggestion will be appreciated.
回答1:
Did you ever dumped __DIR__? Usually there's no / at the end. So you would have to change your code to this:
require_once(__DIR__.'/GoogleClientApi/src/Google/Service/Analytics.php');
^
I just checked in your screen shot with the error message, there's no / at the end.
/Applications/MAMP/htdocsGoogleClientApi/src/Google/Client.php
instead of /Applications/MAMP/htdocs/GoogleClientApi/src/Google/Client.php
回答2:
It turns out I had to set the include path to include the root directory (src folder) using this line :
set_include_path("/Applications/MAMP/htdocs/GoogleClientApi/src/");
回答3:
This worked for me in Client.php
set_include_path(__DIR__.'/../' . PATH_SEPARATOR . get_include_path());
