最近有打算在php下实现一个gtalk的机器人，google了一下发现在Google的code站中已经有一个比较成熟的脚本了-XMPPHP

使用非常简单

<?php

// activate full error reporting
//error_reporting(E_ALL & E_STRICT);

include ‘XMPPHP/XMPP.php’;

#Use XMPPHP_Log::LEVEL_VERBOSE to get more logging for error reports
#If this doesn’t work, are you running 64-bit PHP with < 5.2.6?
$conn = new XMPPHP_XMPP(’talk.google.com’, 5222, ‘username’, ‘password’, ‘xmpphp’, ‘gmail.com’, $printlog=false, $loglevel=XMPPHP_Log::LEVEL_INFO);

try {
$conn->connect();
$conn->processUntil(’session_start’);
$conn->presence();
$conn->message(’someguy@someserver.net’, ‘This is a test message!’);
$conn->disconnect();
} catch(XMPPHP_Exception $e) {
die($e->getMessage());
}
?>

我需要的是能够接受我指令的代码，依然带了一个实例程序

修改了下，让他帮我去网站上查询一个城市当天的天气

<?php

// activate full error reporting
//error_reporting(E_ALL & E_STRICT);

include ‘XMPP.php’;

function get_url($city)
{
$url = ‘http://search.weather.com.cn/static/url_gb.php?CityInfo=’;

ob_start();

$content = ob_get_contents();
ob_end_clean();
$con =htmlspecialchars($content);
$url = strstr($con,’URL’);
preg_match(”(\d+)”,$url,$matches);

$rrr = ‘http://www.weather.com.cn/html/weather/’.$matches[0].’.shtml’;
return $rrr;
}
function get_wether_info($url)
{
#$contents = file_get_contents($url);
$ch = curl_init($url);
ob_start();
curl_exec($ch);
curl_close($ch);
$contents = ob_get_contents();
ob_end_clean();
$w=strstr($contents,’box_contentwea’);
$ww = strstr($w,’strong’);
$sun = substr($ww,7,100);
$next_tag = stripos($sun,’</strong>’);
$wether = substr($sun,0,$next_tag);

$ww = substr($ww,0,100);
$next_tag = stripos($ww,’</em>’);

return $info;

直接发送”w “+城市名（拼音）/城市zip

如“w shanghai”
