Including remote images #9
Description
The is_file check on line 103 prevents the inclusion of remote files (eg, over http). However, file_get_contents will return false if either of the checks in line 103 fail. What do you think of changing base64($file) to read:
protected function base64($file)
{
if (false === ($content = file_get_contents($file))) {
throw new \InvalidArgumentException(sprintf('Cannot read file %s', $file));
}
return base64_encode($file);
}
