PHP file_get_contents returns 404 - php

Question

I have a very strange Problem. I am trying since 3 hours to the the output from $ht. When i echo $ht the result is http://www.google.com. There is no problem. But when i do file_get_contents with the variable $ht there is no output. I tried already with curl also no ouput - 404....
foreach ($hashtweet[1] as $ht)
{
$html = file_get_contents($ht); //NOT WORKING
$html = file_get_contents("http://www.google.com"); // WORKING
echo $html;
//echo $ht; = CORRECT OUT OF $ht = http://www.google.com
}

Answer 1

You should use trim function:
$html = file_get_contents(trim($ht));
Probably some spaces or other white characters are at the beginning or at the end of string
EDIT
In your question you told us the $ht is http://www.google.com but in comment you told is it's google.com. If you want to get http://google.com you need to add http://. Otherwise it means that you need in current directory file with name google.com
EDIT2
So you should compare those 2 strings. Add inside your loop:
if (trim($ht) == 'http://www.google.com') {
echo "same strings<br />";
}
else {
echo "there is difference<br />";
}
to make sure those strings are or aren't the same. You told that your $ht return string(21) "http://www.gooogle.com" so it's impossible it doesn't work because string http://www.gooogle.com string is exactly 21 characters long. Don't you change $ht variable before running file_get_contents or after it inside the loop?
