#41745 [NEW]: PHP incorrectly encodes null values in SOAP

From: jasper at digiweb dot co dot nz Operating system: Linux PHP version: 5.2.3 PHP Bug Type: SOAP related Bug description: PHP incorrectly encodes null values in SOAP Description: ------------ When null is provided for a SOAP parameter or the field of an object passed as a SOAP parameter, PHP incorrectly encodes the parameter as being empty (e.g. object with all null fields, or empty string) which is different from an actual null. This breaks access to real-world web services. Reproduce code: --------------- $soap = new SoapClient('/path/to/wsdl', array('trace' => true)); $soap->operation(null); echo $soap->__getLastRequest(); Expected result: ---------------- <?xml version="1.0" encoding="UTF-8"?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="NAMESPACE" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <SOAP-ENV:Body> <ns1:operation> <paramName xsi:nil="true"/> </ns1:operation> </SOAP-ENV:Body> </SOAP-ENV:Envelope> == OR == <?xml version="1.0" encoding="UTF-8"?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="NAMESPACE"> <SOAP-ENV:Body> <ns1:operation/> </SOAP-ENV:Body> </SOAP-ENV:Envelope> Actual result: -------------- <?xml version="1.0" encoding="UTF-8"?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="NAMESPACE"> <SOAP-ENV:Body> <ns1:operation> <paramName/> </ns1:operation> </SOAP-ENV:Body> </SOAP-ENV:Envelope> -- Edit bug report at http://bugs.php.net/?id=41745&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=41745&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=41745&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=41745&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=41745&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=41745&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=41745&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=41745&r=needscript Try newer version: http://bugs.php.net/fix.php?id=41745&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=41745&r=support Expected behavior: http://bugs.php.net/fix.php?id=41745&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=41745&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=41745&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=41745&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=41745&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=41745&r=dst IIS Stability: http://bugs.php.net/fix.php?id=41745&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=41745&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=41745&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=41745&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=41745&r=mysqlcfg
