ok, here is the story:
I was trying to download remote images, finding urls throught apache indexs with regexps and
fopen()ing them to get the datas. It didn't work. I thought about binary considerations.
Putting the 'b' in the second argument of fopen didn't help much, my browser still
didn't want to display the images. I finally understood by watching the datas i was getting
from the remote host: it was an html page ! hey, i didn't know apache sent html pages when
requesting images, did you ?
the right way is then to send an http request via fsockopen. Here comes my second problem, using
explode("\n\n", $buffer); to get rid of the headers. The right way is to get the value of
the Content-Lenght field and use it in substr($buffer, -$Content-Lenght);
finally, here is my own function to download these files:
<?php
function http_get($url)
{
$url_stuff = parse_url($url);
$port = isset($url_stuff['port']) ? $url_stuff['port'] : 80;
$fp = fsockopen($url_stuff['host'], $port);
$query = 'GET ' . $url_stuff['path'] . " HTTP/1.0\n";
$query .= 'Host: ' . $url_stuff['host'];
$query .= "\n\n";
fwrite($fp, $query);
while ($tmp = fread($fp, 1024))
{
$buffer .= $tmp;
}
preg_match('/Content-Length: ([0-9]+)/', $buffer, $parts);
return substr($buffer, - $parts[1]);
?>
}
ho, maybe you'll say i could have parsed the page to get rid of the html stuff, but i wanted to
experience http a little ;)
