我正在尝试从服务器连续读取。我使用fopensock()方法。每个连接只读取一次数据的问题。每行长度为350位。
这是我的代码:
<?php
$fp = fsockopen("maddress",myport, $errno, $errstr, 30);
if (!$fp) {
echo "$errstr ($errno)<br />'n";
} else {
$out = "GET / HTTP/1.1'r'n";
$out .= "Host: myaddress'r'n";
$out .= "Connection: Close'r'n'r'n";
fwrite($fp, $out);
while ( ($line = fgets($fp)) !== false) {
echo "$line<br>";
};
fclose($fp);
}
?>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title></title>
<script type="text/javascript">
window.onload=refresh;
function refresh(){
getTarget();
setTimeout("refresh();",5000);
}
function getTarget(){
//1-creating object for the request
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
if (window.ActiveXObject) {
try {
xmlhttp = new ActiveXObject('Msxml2.XMLHTTP');
} catch(e) {
xmlhttp = new ActiveXObject('Microsoft.XMLHTTP');
}
}
//2- excute response when it is ready
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById('targetText').innerText==xmlhttp.responseText;
setTimeout("getTarget();", 5000);
}
}
//3- send request to the server
xmlhttp.open("GET","newEmptyPHPWebPage2.php",true);
//4- setting header for the request
xmlhttp.send(null);
}
</script>
</head>
<body>
<label id="targetText"></label>
</body>
</html>
谢谢你的关心!
while ( ($line = fgets($fp)) !== false) {
echo "$line<br>";
}
这会让你进入一个连续的循环，不断地阅读。
