Eclipse IDE and PHPEclipse Debugger_PHP Tutorial

Now let’s look at how to use the Eclipse IDE and PHPEclipse plug-ins and debugger extensions to further aid in the debugging process.

Using PHPEclipse
You may have used Eclipse, but you may not be familiar with it. See Resources for an introduction to the Eclipse platform.
The PHPEclipse plug-in for Eclipse is a popular tool for developing PHP applications. Please start Eclipse and specify the workspace directory as Apache's www directory (c:www on my machine). Now click File > New > Project. The New Project wizard will pop up. Double-click the PHP folder and select PHP Project. Click Next, enter the project name debugArticle, and click Finish.
If your web server is set up to listen on port 80, no modification is required. Otherwise, go to the Navigator window, right-click on the PHP project debugArticle, select Properties, and then click PHP Project Settings. Click Configure Workspace Settings and modify localhost as appropriate or add the port on which the web server listens (for example, http://localhost:8080). Click Apply to complete the setup.
The Navigator window should display the project and a .project file. Right-click on the project as you did before, but this time select New > PHP File. Replace *.php with the name of the PHP file you want to create, test3.php, and click Finish. A new file should appear in the Eclipse IDE. You may need to navigate to the PHP browser at the bottom of the window to view the current output of the PHP file (see Figure 5).

Note that only Windows® users can use the PHP browser as shown in Listing 5. The same functionality can also be used by opening a separate browser window and pointing the browser to the directory where the test script is located.
Now let's demonstrate this application and prove its power.
In the "Using the Debugger" section, you'll learn how to debug PHP applications using Eclipse, PHPEclipse, and the debugger PHP extension you downloaded earlier. Start by learning how to use its syntax parsing feature.
Syntax parsing and underlining
Start by looking at how PHPEclipse provides real-time syntax parsing to help debug PHP applications. To see this feature in action, start by defining test3.php in Eclipse as shown below.

print(,"Hello World!");
?>

Note that the two characters underlined in Listing 4 are underlined in Eclipse, indicating incorrect syntax. Press Ctrl+S to save the file, and the parsing error will be displayed in Eclipse: a red "x" will be added to the line corresponding to the parsing error in the code, as shown in Figure 6.

Now demonstrate the PHP browser. This window provides a preview of the current PHP script, as shown in Figure 6.
Remove the comma (,) from test3.php defined above. Press Ctrl+S to save the file, and watch the PHP browser window update to display Hello World (see Figure 7).

Here's how to set breakpoints in PHP using the debugger.
