Edit report at https://bugs.php.net/bug.php?id=75829&edit=1 ID: 75829 Updated by: requinix@php.net Reported by: marco dot marsala at live dot it Summary: cURL and file_get_contents does not work with URL containing special character -Status: Open +Status: Not a bug Type: Bug Package: URL related Operating System: both Ubuntu and Windows PHP Version: 7.2.1 Block user comment: N Private report: N New Comment: I get an error page if I try visiting that URL in a browser: "Nessuna vendita individuata" / No sale specified Either your URL is wrong, or you need to think about string encodings (URLs are supposed to be UTF-8), or you need be using some sort of escaping on the apostrophe (percent-encoding?), or if you got that page via a form submission then you need to replay the form submission in code, or something else I don't know since I can't even find the right page through Google. Previous Comments: ------------------------------------------------------------------------ [2018-01-17 08:15:37] spam2 at rhsoft dot net the problem lis NOT in DOMDocument->loadHTMLFile() too, it is that you don't escape your input proper which is your job as programmer be it for SQL, URL's or whatever and the idea that this is a bug in a programming language is wrong from the start frankly you even refer to https://bugs.php.net/bug.php?id=48550 [2009-06-15 17:51 UTC] jani@php.net Well, browsers do a lot of thing automatically you need to do yourself when you do it yourself. This is obviously not any bug. (tested with curl on command line with same result..) ------------------------------------------------------------------------ [2018-01-17 08:09:15] marco dot marsala at live dot it I agree with you that is a bad practice to have such characters in URL, but sometimes you have to interact with external websites that use such characters in their URLs (for example when writing a scraper). Btw, the problem is on DOMDocument->loadHTMLFile() too ------------------------------------------------------------------------ [2018-01-17 08:00:04] spam2 at rhsoft dot net https://en.wikipedia.org/wiki/Garbage_in,_garbage_out PHP is a programming language and not a artificial intelligence hence you are responsible as programmer to encode input as needed and have such chars in a URL/filename is bad practice anyways ------------------------------------------------------------------------ [2018-01-17 07:59:09] marco dot marsala at live dot it I don't think is a duplicate of #48550 but a much broader vision of the issue. ------------------------------------------------------------------------ [2018-01-17 07:52:57] marco dot marsala at live dot it Description: ------------ cURL and file_get_contents does not work with URL contanining special characters (for example: accented letters, quotes). The URL sent to the remote server is badly encoded; special characters should be encoded as urlencode() would, like any modern web browser does. Test script: --------------- $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, "https://www.astegiudiziarie.it/vendita-asta-appartamento-genova-via-san-giovanni-d'acri-14-1360824"); echo curl_exec($ch); // got server error page echo file_get_contents("https://www.astegiudiziarie.it/vendita-asta-appartamento-genova-via-san-giovanni-d'acri-14-1360824"); // got server error page // my function to fix encoding function urlencode_parts($url) { $parts = parse_url($url); $parts['path'] = implode('/', array_map('urlencode', explode('/', $parts['path']))); $url = new \http\Url($parts); return $url->toString(); } $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, urlencode_parts("https://www.astegiudiziarie.it/vendita-asta-appartamento-genova-via-san-giovanni-d'acri-14-1360824")); echo curl_exec($ch); // now ok echo file_get_contents(urlencode_parts("https://www.astegiudiziarie.it/vendita-asta-appartamento-genova-via-san-giovanni-d'acri-14-1360824")); // now ok Expected result: ---------------- The script should download the same page you can see with a web browser. Actual result: -------------- The server replies with a server error page. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=75829&edit=1
