PHP实现Soap通讯的方法

<?php
function HttpSoap($server,$port,$url,$namespace,$action,$data) {
$fp = @fsockopen($server,$port);
if (!$fp) {
return FALSE;
} else {
$soapData = ConstructData($namespace,$data);
$length = strlen($soapData);
$out = "POST $url HTTP/1.1rn";
$out .= "Host: $serverrn";
$out .= "Content-Type: text/xml; charset=utf-8rn";
$out .= "Content-Length: $lengthrn";
$out .= "SOAPAction: "$namespace$action"rnrn";
$out .= $soapData;
$out .= "rnrn";
fputs($fp,$out);
stream_set_timeout($fp,2);
$header = "";
while($line = trim(fgets($fp))) {
$header .= $line."n";
}
$dataPos = strpos($header,"Content-Length: ") + 16;
$dataEnd = strpos($header,"n",$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,$data) {
$soapData = "
<?xml version="1.0" encoding="utf-8"?>
rn";
$soapData .= "<soap:Envelope xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="rn'>http://schemas.xmlsoap.org/soap/envelope/">rn";
$soapData .= " <soap:Body>rn";
$soapData .= " <$action xmlns="$namespace">rn";
foreach($data as $name => $value) {

}
$soapData .= " </$action>rn";

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);
