判断Keep-Alive模式的HTTP请求的结束的实现代码

复制代码 代码如下:

// $fp是由fsockopen()产生的句柄
while(!feof($fp)) {
echo fgets($fp);
}

复制代码 代码如下:

$length = 0;
$line = '';
while($line !== "/r/n") {
$line = fgets($fp);
if(substr($line, 0, 15) === 'Content-Length:') {
$length = intval(substr($line, 16));
}
}

复制代码 代码如下:

$sum = 0;
while($sum < $length) {
$line = fgets($fp);
$sum += strlen($line);
echo $line;
}
