Example of installing and using the Soap module in PHP

The SOAP extension in PHP5 aims to implement PHP's support for Web services. Unlike other methods that implement PHP's support for Web services, SOAP extensions are written in C, so they have a speed advantage over other methods.

SOAP extensions support the following specifications.

* HTTP 1.1
* Http 1.2
* WSDL 1.1

SOAP extensions are mainly used to process RPC Web services. However, you can also use text-format WSDL files to work with the server and client in the WSDL mode.

1. Install the soap module in Linux
After installing php, it is best to keep the files installed at that time, such as usr/local/php-5.3.2
To check whether the soap module is installed, run php-m in the php installation directory.

For example:/usr/local/php/bin/php-m | grep 'Soap'
If no installation is available, go to the php installation source folder.
Cd php-5.3.2/ext/soap
Run the phpize command here.
/Usr/local/php/bin/phpize
Check whether the information has an error. If there is no error, run the following command:
./Configure-with-php-config =/usr/local/php/bin/php-config-enable-soap
Then install and compile
Make
Installation
Make install
After installation, a message is displayed, indicating the path to save the soap. so file.
The compiled soap. so file is saved in the/usr/local/php/lib/php/extensions/no-debug-non-zts-20111222 directory, and then the php. Ini file is modified.
Manually modify: Search for extension_dir = "./" in/usr/local/php/etc/php. ini. It is commented out by default.
Change to extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20111222 /"
Add the following after this line, and then save:
Extension = "soap. so"
Restart apache and run php-m to view the extended soap module.
If you want to install extension modules, you can do so.

II. Install the soap module in Windows

In Windows, you can modify php. ini to select which extension libraries are loaded when PHP is started. You can also use dl () to dynamically load data in the script. All DLL files in the PHP Extension Library have the php _ prefix. Many extension libraries are built into PHP for Windows. This means that no additional DLL files or extension configuration commands are required to load these extension libraries. The PHP Extension Library list in Windows lists the extension libraries that require or have previously required additional php dll files.
To be in php. to enable an extension Library in ini, remove the extension = php _ * line _*. the annotation symbol before the dll. Delete the semicolon (;) before the extension library to be loaded.
Enable php_soap.dll Extension Library
// Set this line
; Extension = php_soap.dll
// Change to this
Extension = php_soap.dll
Note: If you run PHP for the server module version, do not forget to restart the web server after modifying php. ini to make the change take effect.

How to use the SOAP module

First, let's take a look at the three main objects of SOAP extensions:
1. SoapServer

The code is as follows:

Copy code

SoapServer is used to define the functions that can be called and return response data when creating a php server page. The syntax format for creating a SoapServer object in NON-WSDL mode is as follows: $ Soap = new SoapServer (null, $ arr ); $ Arr is the property information of SoapServer and an array. The addFunction method of the SoapServer object is used to declare which function can be called by the client. The method is as follows: $ Soap-> addFunction ($ functionName ); $ FunctionName is the name of the method that can be called by the client. If all methods can be called, use the following method: $ Soap-> addFunction (SOAP_FUNCTIONS_ALL ); The handle method of the SoapServer object is used to process user input, call the corresponding function, and finally return the result to the client for processing. The usage is as follows: $ Soap-> handle ([$ soapRequest]);

$ SoapRequest is an optional parameter used to indicate the user's request information. If $ soapRequest is not specified, the server receives all user requests.
2. SoapClient

SoapClient is used to call the SoapServer page on the remote server and call the corresponding function. The method for creating a SoapClient object is as follows:

The code is as follows:	Copy code
$ Client = new SoapClient (null, $ arr );

The $ arr parameter is the same as the SoapServer parameter. After the SoapClient object is mounted, the method for calling the server side is as follows:

The code is as follows:	Copy code
$ Client-> functionName ($ p );

FunctionName () is the name of the function to be called on the server, and $ p is the parameter.
3. SoapFault

SoapFault is used to generate possible errors during soap access. The method for creating a SoapFault object is:

The code is as follows:	Copy code
$ Fault = new SoapFault ($ code, $ msg );

The parameter $ code is the user-defined error code, and $ msg is the user-defined error message. The soapFault object is automatically generated when an error occurs on the server page or when you create a SoapFault object. For errors during Soap access, the client can capture the SoapFalut object to obtain the corresponding error information. After capturing the SoapFault object on the client, you can use the following code to obtain the error code and error message:

The code is as follows:	Copy code
$ Fault-> code; // error code $ Fault-> msg; // error message

The above is the introduction of three main objects of the php soap module. Here we will use a simple example to help you understand how to use the soap module.
4. php soap instance (NON-WSDL mode)

Server code server. php:

The code is as follows:	Copy code
<? Php $ Arr = array ( 'Location' => 'http: // 192.168.187.132/server. Php ', 'URL' => 'http: // 192.168.187.132 /' ); $ Soap = new SoapServer (null, $ arr );     $ Soap-> addFunction (SOAP_FUNCTIONS_ALL); // allows the client to call all methods $ Soap-> handle (); Function (){ Return 'Lee's blog ';     }   Function B ($ B ){ Return $ B;     }

           

Client code:

The code is as follows:	Copy code
<? Php $ Arr = array ( 'Location' => 'http: // 192.168.187.132/server. Php ', 'URL' => 'http: // 192.168.187.132 /' ); $ Soap = new SoapClient (null, $ arr );     Echo $ soap-> a (), '<br/> '; Echo $ soap-> B ('B '); ?>
