Why does it return 404 if the url is correct?

Question

PHP

Good afternoon. You need to parse images from the site. I have a list of links and in the code I'm trying to issue a request in the form:

$value = removeBOM($value);
$str = 'http://mysite.ru/'.$value;
$sContent = file_get_contents($str);

removeBOM removes encoding marker bits. I have $value, which is issued in a cycle from a csv file (everything is in order with it and gives out what is needed). When executed, it proudly writes to me:
failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found
A direct link with the same characters is fine. I am writing a parser for the first time, so everything may not be as it should)
What could be?

Answer 1

1) var_dump ($value) should be done and make sure that the visible length matches the real one.
2) urlencode
3) punycode
file_get_contents, unlike the browser, does not encode the url, does not cut out invisible characters (at the end of $ value there may be a line break), and passes the encoding as is, which is critical for site.ru/url- Russian.

Answer 2

It seems to me that the encoding bits should be removed from the file and from the value variable.
In addition, it is possible in the PHP settings that it is forbidden to receive files cross-domain. Check
with Ideshka see what goes into str

Answer 3

Have you tried it without removeBOM?
