Urlencode and file_get_contents
We have an url like http://site.s3.amazonaws.com/images/some image @name.jpg inside $string
What I'm trying to do (yes, there is a whitespace around the url):
$string = urlencode(trim($string));
$string_data = file_get_contents($string);
What I get (@ is also replaced):
file_get_contents(http%3A%2F%2Fsite.s3.amazonaws.com%2Fimages%[email protected])[function.file-get-contents]: failed to open stream: No such file or directory
If you copy/paste http://site.s3.amazonaws.com/images/some image @name.jpg into browser address bar, image will open.
What's bad and how to fix that?
Answer
Using function urlencode() for entire URL, will generate an invalid URL. Leaving the URL as it is also is not correct, because in contrast to the browsers, the file_get_contents() function don't perform URL normalization. In your example, you need to replace spaces with %20:
$string = str_replace(' ', '%20', $string);
