First, what is PEAR
PEAR is an abbreviation for PHP Extension and Application Repository (PHP extension and application library). PEAR provides a basic class library for PHP users, simplifies our workload by calling the PHP program. For a very simple example, for example, I want to set the data in the database through the WEB page, and extract the corresponding data to the Excel form. To complete this task, it is not easy to do before, but now there is a pear, and we can implement the write operation of Excel in a short time by calling the Spreadsheet class inside the pear. Long-term short say, or start our PEAR installation trip.
Second, install PEAR
First introduce my system environment:
WINDOWS 2000
WAMP1.4.3 (Apache 1.3.33 PHP 5.0.3 mysql 4.1.8)
Everyone may be more unfamiliar with Wamp, I will introduce: well known, to install these three software in the Windows environment, still need to be impressed. And Wamp (Windows Apache MySQL PHP) can help us do not need any configuration, as long as it go to its official website
Http://www.wampser.com/en/download.php Download a file called wamp5_1.4.3.exe, then run the installation directly, you can build a set of Apache / MySQL / PHP / It's not easy to use the environment.
Ok, after the system is configured, let's install the pear next step. Starting from PHP 4.04, Pear is distributed together with the PHP core. Enter the PHP installation directory, double-click Go-pear.bat, pop up a command prompt window, display the following information:
Welcome to go-pear!
Go-Pear Will Install the 'pear' Command and all the files needed by
It. This Command is your Tool for pear installation and maintenance.
Go-pear also lets you downline and install the pear packages bundled
With php: db, net_socket, net_smtp, mail, xml_parser, phpUnit.
IF you wish to Abort, Press Control-C Now, or Press Enter to Continue:

1-7, 'All' or Enter to Continue:
Set up the system environment related to PHP, if you use the PHP installed by Wamp, then
It will be directly carried here. After pressing the Enter key, the following information is displayed:

Then save the exit.
Note: D: / Software / Wamp / PHP / PEAR
This directory is based on PHP / PEAR
The actual installation directory is filled out.
Ok, I have been installed here, is it very simple, basically run Go-pear.bat, it is possible to enter the bus along the way.
Third, install and use PEAR
Spreadsheet_excel_writer
Recrete EXCEL
form
Friends who have not used Pear may not know very well on PEAR, here we will give a simple example to explain. First enter the installation directory of PHP. Perform the following command:
Pear Download OLE
Pear Download Spreadsheet_excel_writer
Description: Pear Download Package represents Download related package.
Pear Install OLE-0.5.tgz
Pear install spreadsheet_excel_writer-0.8.tgz
Description: Pear Install PackageName represents the installation related packagename. More commands on PEAR and meaning can be viewed. After installation, execute the Pear List, if you see the following 2 line, you will explain the installation.
OLE 0.5 beta
Spreadsheet_excel_writer 0.8 Beta
Then we build a Test.php file in the WWW directory, the content is as follows:
INCLUDE_ONCE "Spreadsheet / Excel / Writer.php";
$ xls = & new spreadsheet_excel_writer ();
$ XLS-> Send ("Test.xls");
$ Sheet = & $ XLS-> Addworksheet ('Test Results');
$ Sheet-> Write (0,0,12);
$ Sheet-> Write (0, 1, "Hallo, Ich Bin Ein Text");
$ FORMAT = & $ XLS-> addformat ();
$ FORMAT-> setBold ();
$ FORMAT-> SetColor ("Green");
$ Sheet-> Write (1, 1, "Hallo, Ich Bin Formatiert", $ FORMAT);
$ xls-> close ();
?>
Then run directly. At this point IE browser pops up a dialog box for downloading the Test.xls file. After downloading, you can see the generated Excel table file. Specific spreadsheet_excel_writer generates the Excel form format syntax, you can refer to the official manual of PEAR, here is not said. Ok, our Pear tour is over here. Have you started interested in PEAR, then you can't try it!
