On hosts with safe_mode turned on, it can be difficult to get remote files with a system call to wget or curl. Here is a PHP function that will get a file with an HTTP GET. I use it to download remote images. It returns the binary data in a variable that can be written to a file.
<?php
function http_get_file($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, $query);
while ($line = fread($fp, 1024)) {
$buffer .= $line;
}
preg_match('/Content-Length: ([0-9]+)/', $buffer, $parts);
return substr($buffer, - $parts[1]);
}
?>
function http_get_file($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, $query);
while ($line = fread($fp, 1024)) {
$buffer .= $line;
}
preg_match('/Content-Length: ([0-9]+)/', $buffer, $parts);
return substr($buffer, - $parts[1]);
}
?>
