$document=$proxy->document;echo <<<SoapDocument<?xml version=”1.0″ encoding=”GB2312″?><SOAP-ENV:Envelope SOAP-ENV:encodingStyle=”http://schemas.xmlsoap.org/soap/encoding/” xmlns:SOAP-ENV=”http://schemas.xmlsoap.org/soap/envelope/” xmlns:xsd=”http://www.w3.org/2001/XMLSchema” xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance” xmlns:SOAP-ENC=”http://schemas.xmlsoap.org/soap/encoding/” xmlns:si=”http://soapinterop.org/xsd“><SOAP-ENV:Body>$document</SOAP-ENV:Body></SOAP-ENV:Envelope>SoapDocument;
Copy after login

顺便问一下在PHP中出现下面这种形式?会冲突吗?该怎么解决?
<?php<??>?>
Copy after login


回复讨论(解决方案)

把被 SoapDocument 括起的内容作为一个字符串输出

在启用了短标记的情况下

 
?>
?>
将产生语法错误!
