用php实现soap通讯

用PHP实现Soap通讯

近日用PHP实现Soap通讯，写了一些简单的方法：
引用文字

<?
php
function HttpSoap($server, $port, $url, $namespace, $action, $data) {
$fp = @fsockopen($server, $port);
if (!$fp) {
return FALSE;
} else {
$soapData = ConstructData($namespace, $action, $data);
$length = strlen($soapData);

$out = "POST $url HTTP/1.1 ";
$out .= "Host: $server ";
$out .= "Content-Type: text/xml; charset=utf-8 ";
$out .= "Content-Length: $length ";
$out .= "SOAPAction: "$namespace$action" ";
$out .= $soapData;
$out .= " ";

fputs($fp, $out);
stream_set_timeout($fp, 2);

$header = "";
while($line = trim(fgets($fp))) {
$header .= $line." ";
}
$dataPos = strpos($header, "Content-Length: ") + 16;
$dataEnd = strpos($header, " ", $dataPos);
$dataLength = substr($header, $dataPos, $dataEnd - $dataPos);
$data = "";
if($dataLength > 0) {
$data = fread($fp, $dataLength);
}
fclose($fp);
if(strlen($data) != $dataLength || $dataLength <= 0) {
return FALSE;
}
return $data;
}
}

function ConstructData($namespace, $action, $data) {
$soapData = "
<?xml version="1.0" encoding="utf-8"?>

";
$soapData .= "<soap:Envelope xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap=" ">http://schemas.xmlsoap.org/soap/envelope/"> ";
$soapData .= " <soap:Body> ";
$soapData .= " <$action xmlns="$namespace"> ";
foreach($data as $name => $value) {
$name = iconv("GBK","UTF-8",$name);
$value= iconv("GBK","UTF-8",$value);
$soapData .= " <$name>$value</$name> ";
}
$soapData .= " </$action> ";
$soapData .= " </soap:Body> ";
$soapData .= "</soap:Envelope>";

return $soapData;
}

<?
$data=array(
"user"=>"测试", //如果需要输入二进制数据请采用BASE64编码
"pass"=>"test"
); 
echo HttpSoap("sample.anyhost.com", 80, "/sampleSoap.asmx", "http://tempuri.org/", "logIn", $data);
?>
