ID: 31923 Updated by: [EMAIL PROTECTED] Reported By: mike-bugs dot php dot net at webheat dot co dot uk Status: Bogus Bug Type: Filesystem function related Operating System: Linux PHP Version: 4.3.10 New Comment:
It should be RFC883 (page 56) not RFC833. http://www.faqs.org/rfcs/rfc883.html "The labels must follow the rules for ARPANET host names. They must start with a letter, end with a letter or digit, and have as interior characters only letters, digits, and hyphen."

Btw, could you post a link to the RFD you are quoting from. I searched on Google and found an RFC entitled "Who talks TCP?" Thanks ------------------------------------------------------------------------ [2005-02-11 21:36:12] [EMAIL PROTECTED] Please refer to RFC833 Appendix 1. Hyphens may not appear at the start or end of a <label>. gethostbyname() (Used by the network streams code among other parts of PHP) treats this correctly according to RFC specification. Your browser is simply more forgiving. ------------------------------------------------------------------------ [2005-02-11 08:53:38] mike-bugs dot php dot net at webheat dot co dot uk The urls are as an example, http://emdeeuk.deviantart.com/ does work. The url that identified the problem is: http://mark-.deviantart.com/ A hyphen is valid in DNS. ------------------------------------------------------------------------ [2005-02-11 04:44:02] [EMAIL PROTECTED] Those urls of yours don't work even in browser, why should they magically work in PHP?? (is - valid in DNS anyway?) ------------------------------------------------------------------------ [2005-02-11 01:59:34] mike-bugs dot php dot net at webheat dot co dot uk Description: ------------ A script I created ( http://webheat.co.uk/forumbuddy.php ) takes a username for the site DeviantArt.com which forms parts of the user's section of the site. The url takes the form of: http://USERID.deviantart.com/ The script grabs one or more pages by using the file_get_contents() function. Regardless of whether I use urlencode()/rawurlencode() and urldecode() the file_get_contents() function chokes with the error as detailed below. This only happens when the userid ends in a hypen. After some testing it seems to be that this is because the hyphen is then next to a period "-." This hyphen period combination causes an error regardless of where it is placed in the user id. This issue happens on my host's server but not on two other [Windows] machines I've tested this code on. The hosting company have gone through their php.ini file on my behalf and whilst the file is not vanilla there are no differences that they can see would affect this fuction. Reproduce code: --------------- The relevant code is as follows: file_get_contents("http://emdeeuk-.deviantart.com";); //Doesn't work file_get_contents("http://emdee-.uk.deviantart.com";); //Doesn't work file_get_contents("http://emdeeuk.deviantart.com";); //Does work The full code can be viewed here: http://webheat.co.uk/forumbuddytest.php.txt Expected result: ---------------- <a href="http://www.deviantart.com/deviation/14935843/";>Dogs on Kites</a> <a href="http://www.deviantart.com/deviation/14935312/";>Welcome to the Rat Race</a> <a href="http://www.deviantart.com/deviation/14934730/";>Arc de Bishopsgate</a> <a href="http://www.deviantart.com/deviation/14592356/";>PLEASE VOTE: New Webheat.co.uk</a> <a href="http://www.deviantart.com/deviation/14586143/";>Docklands Sunbathing</a> <a href="http://www.deviantart.com/deviation/14556463/";>Slide PSP8 Frame</a> <a href="http://www.deviantart.com/deviation/14556193/";>Whitechapel Horse</a> <a href="http://www.deviantart.com/deviation/14521593/";>Action Squirrel</a> <a href="http://www.deviantart.com/deviation/14520802/";>Beady Eye of the Plottin Drake</a> <a href="http://www.deviantart.com/deviation/14485015/";>Light House II</a> <a href="http://www.deviantart.com/deviation/14377961/";>Polaroid Photo Frames</a> <a href="http://www.deviantart.com/deviation/14217085/";>Now where's the Sphinx?</a> <a href="http://www.deviantart.com/deviation/14213953/";>Something in the Aer</a> <a href="http://www.deviantart.com/deviation/14125157/";>I Sea Gulls</a> <a href="http://www.deviantart.com/deviation/14124660/";>Coots really get my Goose</a> <a href="http://www.deviantart.com/deviation/13932181/";>Spoonful of sugar</a> <a href="http://www.deviantart.com/deviation/13757002/";>Ugly Emotion</a> <a href="http://www.deviantart.com/deviation/13729717/";>Light House</a> <a href="http://www.deviantart.com/deviation/13729376/";>Ilm Tree</a> <a href="http://www.deviantart.com/deviation/13705596/";>Only ugly on the inside</a> <a href="http://www.deviantart.com/deviation/13639781/";>Lava Lamponians</a> <a href="http://www.deviantart.com/deviation/13597782/";>Generations</a> <a href="http://www.deviantart.com/deviation/9434166/";>Flame Mobile Wallpaper</a> <a href="http://www.deviantart.com/deviation/9421010/";>Flame Body Work Wallpaper</a> Actual result: -------------- Warning: file_get_contents(): php_network_getaddresses: getaddrinfo failed: Name or service not known in /home/webheat/public_html/forumbuddytest.php on line 6 Warning: file_get_contents(http://USER-.deviantart.com/gallery/?view=3&order=5&limit=24&offset=0): failed to open stream: Permission denied in /home/webheat/public_html/forumbuddytest.php on line 6 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=31923&edit=1
