Hi
I have a HTML-Form where user's can enter their website-address. Some of you know the
resulting problem for sure: most users enter "www.php.net", some users enter
"http://www.php.net"; and some others enter "http://www.php.net/";. The last version is
IMHO the most correct form. ("http://www.php.net"; is commonly used, but afaik it's
either the webbrowser or the webserver which appends the missing /).
So my problem was to rewrite the url's so that entered URL's will be displayed
correct, no matter how the user entered it. For this purpose I wrote following
function:
function rewriteURL($url, $base=""){
$purl = parse_url($url);
if (!isset($purl['scheme']) || (!$purl['scheme'])){
$url = "http://".$url; }
$purl = parse_url($url);
if ((!isset($purl['path'])) || (!$purl['path'])){
$url .= '/'; }
return $url;
}
My Questions:
-Are there URLs which could be entered correct and become wrong when rewritten with
that function? (Yes, I have tested the function myself, but there are too many
possibilities so it's impossible for me to cover all of them)
-What was the best way to check, if the give address really exists? (I thought on a
test like this:
$exists = true;
@fopen($url) or $exists = false;
return $exists;)
TIA
