When talking about PHP Web service calls, people in the PhP4 age will immediately think of using nusoap to call the service. This nusoap is a good thing, but it has not been updated for a long time. It is feared that there will be many vulnerabilities, it's already in the PhP5 era. It's not quick to call the built-in extensions of
PHP has two extensions to implement Web service, one is Nusoap, one is the official PHP SOAP extension, because soap is official, so here we use SOAP to implement the Web Service. Because the SOAP extension is not turned on by default, let's see if the SOAP extension is open.In the process of writing

The results you receive are encoded using XML/SOAP. You can use XSLT to convert XML, or use an XML parser to read the desired value from XML. However, the work of writing XML parsers is tedious.

Introduction
Web services have been around for a long time. The first is soap, but soap only describes the message, followed by WSDL.

In that case, it might be logical to elaborate on soap before discussing rest.What is SOAP?SOAP (Simple Object Access Protocol), as its name implies, is a tightly defined information exchange protocol used to encapsulate remote calls and returns in a Web service into machine-readable formatted data. In fact, SOAP data uses an XML data format that defines a complex set of tags that describe the remo
