Some PHP code worked well. However, when I port the code into a Drupal module, the $fp = fopen( 'language/unicode-big5.tab', 'r' ); does not work as expect, giving a warning:
warning: fopen(language/unicode-big5.tab) [function.fopen]: failed to open stream: No such file or directory in /Users/me/Documents/Html/drupal/sites/all/modules/test_module/language.inc.php on line 197.
I tried to put the required files and folder in sites/default/files:
$fp = fopen( file_directory_path().'/language/unicode-big5.tab', 'r' );
returns the same warning.
How can I fix it?
That will work perfectly fine.
However the message is simply stating that your path is wrong, have you tried a simply looking at what path it’s trying to open?
Just do the following, and correct the path accordingly.
If the path is correct, then you need to check permissions, does that user have access to the file at all? Try a chmod 777 and see if that helps the issue, if it does, remove the chmod 777 and fix it accordingly (user/group permissions).
