, JDBC, JNDI, JAVABEAN, EJB, and so on. The Java EE is particularly well-suited for large enterprise applications.Second, database access comparisonJava accesses the database through JDBC and provides easy access to the database through database drives provided by different database vendors. The interface to access the database is more uniform.PHP has different database access interfaces for different databases, so the database access code is not very versatile. For example, a

modification from the MySQL database to the Oracle database. and PHP needs to do a lot of modification work. Third, the system design architecture comparison Using Java Web Development technology, it is necessary to use the object-oriented system design method, and PHP is a

needed when you start Apache from the command line. (3) Modify DocumentRoot Apache access to the home folder directory, is the PHP, HTML code file location. The default path for Apache is under Htdocs (E:\Apache24\htdocs), which has a simple entry file index.html. This path can be modified on its own, and I am here to configure it under my own new folder www (E:\php\www). (247 lines) DocumentRoot "C:/apa

of servlet and JavaBean. JavaBean is a reusable, cross-platform software component. The use of JavaBean can facilitate the separation of Java code and HTML, and can enhance the function of the system and the reusability of software. Java Web Development is a specification of Sun's definition of EE. And it includes all aspects of Java Web

, Apache supports php,cgi,jsp and can run on many platforms, although Apache is the world's top-ranked Web server platform, but it is well known that Windows is famous for its ease of use. And therefore occupy a lot of server market.Our common development portfolio:In the IIS environment1.asp+access2.asp+sql SERVER3.asp.net+access4.asp.net+sql SERVERApache Enviro

is not strong. For example, only a few modifications are required to switch a Web application developed in Java from a MySQL database to an Oracle database. PHP requires a lot of modification. III. system design architecture comparison Using Java Web development technology,

example, a Web application developed in Java requires little modification from the MySQL database to the Oracle database. and PHP needs to do a lot of modification work.Third, the system design architecture comparisonUsing Java Web Development technology, it is necessary to

rapidly. I believe that such support will increase in the near future. 5. commercial applications cannot be developed. Since php does not have any coding development work, all development is based on script technology. Therefore, all source code cannot be compiled. Therefore, the completed application can only be used by itself or internally and cannot be comme

based on scripting technology to complete. So all the source code can not be compiled, so the application can only be done by themselves or internal use, can not achieve commercialization. Summarize: Applicable to the people: familiar with the UNIX environment, the need for a minimum of input to complete the rapid application development. Applicable platform: Freebsd/linux/unix operating system, Apache server application: High Internet access, rap

8 tips for PHP and MySQL development. 1. when using arrays in PHP to operate databases, it is very helpful to use an associated array (associatively-indexedarrays). let's look at an array traversal in the basic numeric format: 1. Use of arrays in PHP It is very helpful to u

In the eyes of most network dev, ASP programming and JSP programming are considered to be the front-runner, and PHP script is considered a weak "struggling", or it is a language to be used as an amateur, not value to participate in Enterprise Network Dev competition. In my opinion, the reason PHP script is not considered a competitor is that the reviewer lacks knowledge of it and does not know about other o

. of course, oracle, DB2, and other large applications can be installed in Linux.DatabaseBut they are expensive. JSP and PHP are the most popular and widely used web development languages.

Php variables have four scopes:1. local variables The variables declared in the function are local variables and can only be referenced in the function. $ X = 4; function assignx () {$ x = 0; print ("A result is :". $ x); // although the same name is used, only the internal variable} assignx (); print ("B result is :". $ x); // outside, variables with external scopes will be used ---- A result is: 0. this is the result of assignx () execution.
