file_put_content（）文件权限错误

Question

On my code I am sending url encoded image and using file_out_content to turn it to a file.

    if(file_put_contents($arg['org_file'],$decodeData))
    {
        chmod($arg['org_file'],777);
        $arg = Model_Photo::_convert_png_to_jpg($arg);

        //reduce file
        \Fuel\Core\Image::load($arg['org_file'])
                ->config('quality',80)
                ->resize($arg['width'])
                ->save($arg['org_file'],755);

When my execution gets the code above. the part with the Image::Load I get this error.

Fuel\Core\PhpErrorException [ Warning ]:
getimagesize(/www/my.website.com/public/uploads/2013-11-18/4511582301f8b92b08aad0b8e.jpg): failed to open stream: Permission denied

You can see that I chmod the created file to 777, but looking at the console the permission is not 777.

--wxrw--wt 1 apache apache 291301 Nov 18 18:07 4511582301f8b92b08aad0b8e.jpg

The absence of read make it problematic for me to do file manipulation. I did the chmod but it is not working, so I think I am missing something. Kindly help, thanks!

Answer 1

Well, just 777 is not the same as the octal representation that *nix uses. You need to add the 0 prefix to indicate the number is meant to be octal.

chmod($arg['org_file'], 0777);

Update

The same goes for your call to ->save() :

->save($arg['org_file'], 0755);

To illustrate:

777  = 1100001001 (01411)
0777 =  111111111

Answer 2

尝试chmod($arg['org_file'],0777);
