PrefaceFor example, PHP can be used as an embedded Statement of HTML, and it is easy to set up and efficient to work with the Apache Web Hosting Server.PrefacePHP is a simple syntax script language and can be used as an embedded HTML language. It is easy to set and efficient with Apache Web server. Java is a showcase for commercial purposes. It has many useful programs and many Web application development frameworks ). Java is an excellent object-oriented language for commercial purposes. It has many useful libraries and many Web application development frameworks ). Compared with other PHP and Java, PHP's commercial application programs are lacking, while Java's coding and development environments are set to programming languages. Comparing PHP and Java, PHP lacks commercial application libraries, and Java syntax and development environment settings are more complex. Therefore, Web developers should not accept the opinions of PHP or Java, but should adapt to the time limit, which is the combination of the two programming languages of PHP and Java, in order to develop Web applications more efficiently. Therefore, Web developers should review the current situation and combine the advantages of PHP and Java to develop Web applications more efficiently. This article will introduce three different PHP and Java integrated development technologies, hoping to provide an integrated testing environment for building PHP and Java Web development. This article will introduce three different Integrated Development Technologies for PHP and Java, hoping to provide reference for building an integrated environment for PHP and Java Web development.

Three Web development integration technologies for PHP and Java
　　
Currently, known Web development and integration technologies of PHP and Java can be divided into three types: SOAP (Simple Object Access Protocol), Quercus, PHP/Java Bridge, these technologies allow PHP and Java to use each other's programs when developing Web applications.Integration of three PHP and Java Web Development Technologies

Currently, the integration of PHP and Java Web development technology can be divided into three types: SOAP (Simple Object Access Protocol), Quercus, and PHP/Java Bridge, these technologies allow PHP and Java to use each other's libraries when developing Web applications. This article focuses on how to use Java program libraries in PHP programs and how to configure suites such as SOAP, Querus, PHP, and Java Bridge. This article focuses on how to use Java libraries in PHP programs and how to configure suites such as SOAP, Querus and PHP/Java Bridge.

List-1 HelloService. java List-1 HelloService. java

The following describes how to integrate PHP with SOAP, Querus, and PHP/Java Bridge Technology to call echoHello ("Jason "), and get the response result of "Java say hello to Jason. The following describes how to integrate PHP with SOAP, Querus, and PHP/Java Bridge Technology to call echoHello ("Jason") and get the execution result of "Java say hello to Jason.

1. SOAP (Simple Object Access Protocol) 1. SOAP (Simple Object Access Protocol)

SOAP is developed by IBM, Microsoft, and other companies. It is used as a benchmark for distributed object technologies. SOAP is a protocol developed by IBM, Microsoft, and other companies. It is recommended by W3C to implement distributed object technology. SOAP provides a set of machines that use XML to package program calls, dynamic data transfer, and response messages. With the features of XML plain text, attackers can use HTTP, HTTPS, SMTP, and other communication channels to access enterprise-level fire protection channels, compared with distributed object technologies such as CORBA, Java RMI, and DCOM that provide data in binary format, SOAP has the following features. SOAP provides a set of mechanisms for packaging program calls, parameter transmission, and message return in XML. With the characteristics of XML plain text, it can pass through the enterprise's firewall through communication channels such as HTTP, HTTPS, and SMTP, compared with the distributed object technology protocols that transmit data in proprietary binary formats, such as CORBA, Java RMI, and DCOM, SOAP has features unrelated to programming languages, platforms, and hardware.

Apache Axis2 is the most commonly used SOAP suite in Java, and PHP is the php-soap extension module. Apache Axis2 is the most commonly used SOAP suite in Java, and PHP is the php-soap extension module. The following describes how to integrate PHP and Java through the two SOAP suites. The following describes how to integrate PHP and Java through the two SOAP suites.

The service deployment information of HelloService. java is shown in List-2. The service deployment information of HelloService. java is shown in List-2. The name of the service depends on the name of the service. The service name attribute defines the service name. Apache Axis2 uses the service name to construct the server's End Point address, such as http: // localhost: /Axis2/services/ . Apache Axis2 uses the service name to create the service endpoint address, such as http: // localhost: /Axis2/services/ . Therefore, the end point of the HelloService service is http: // localhost: /Axis2/services/HelloService. Therefore, the endpoint address of the HelloService service is http: // localhost: /Axis2/services/HelloService. The ServiceClass category number specifies the type of service response. The ServiceClass parameter specifies the service category. Each Element defines the configuration of an operation in the service. Each Element defines the configuration of an operation in the service. The name attribute of should be set to the name of the method in the server response class. The name attribute of should be set to the name of the method in the corresponding category of the service. The messageReceiver element defines the message receiver that processes this operation. The messageReceiver element defines the Message Receiver used to process this operation.

(5) connect http: // localhost: 8080/sayHello2.php with the ingress connector, resin application server will send $ RESIN_HOME/webapps/ROOT/sayHello2.php to quercuz to compile corresponding java programs, and then parse and parse the lines, the resin application server Returns "Java say hello to Jason", which is displayed on the worker plane. (5) Use a browser to connect to http: // localhost: 8080/sayHello2.php. The resin application server will send $ RESIN_HOME/webapps/ROOT/sayHello2.php to the corresponding java program, then compile and execute the program. Finally, the resin application server Returns "Java say hello to Jason", which is displayed in the browser.

To integrate PHP and Java with Quercus and resin, you only need to install JDK and resin application server (including Quercus ), if you want to collect data, you need to install other data storage servers, such as MySQL Server, the infrastructure is simpler than the integration of SOAP and PHP/Java Bridge. To integrate PHP and Java with Quercus and resin, you only need to install JDK and resin application server (containing Quercus). to connect to the database, you need to install other database servers, such as MySQL Server, environment setting is easier than integrating SOAP with PHP/Java Bridge. However, Quercus and PHP/Zend Engine have compatibility issues. However, quercuus has compatibility issues with PHP/Zend Engine.

Iii. PHP/Java Bridge Iii. PHP/Java Bridge

The interface of Java and script syntax is defined as JSR 223, and JSR is the Specification of Java Specification Requests. The interfaces of Java and script are defined in JSR 223, which is short for Java Specification Requests. JSR 223 defines an interface for creating Java-type entities, call methods, and deliverables from the script statement, it also defines the method for calling script statement from Java, the number of repeated statements, and the method for calculating the return value. JSR 223 specifies the establishment of interfaces for Java class entities, call methods, and result objects from the script language, as well as the methods for calling the script language from Java, conversion parameters, and return value. The following describes how to use the PHP/Java Bridge Suite to enable PHP to use the Java program connector. PHP/Java Bridge is the Java interface of PHP 5 of JSR 223. The following describes how to use the PHP/Java Bridge Suite to allow PHP to use the Java library. PHP/Java Bridge is the Java interface Implementation of PHP 5 in JSR 223.
