Here are some common questions under the Zend Studio series, which may be helpful to everyone:
1) **Q: What is the difference between the Client version and Server version of Zend Studio?**
**A:** The default debugging method in Zend Studio is local debugging, meaning you don't need Apache or a PHP environment set up. You can start debugging as soon as you open Zend Studio. The so-called Zend Server refers to uploading the code from the Zend Studio client to the server and then returning the debugging results. This method also includes debugging tools such as breakpoint debugging, watchpoints, and step-by-step debugging. Additionally, you can use the profiling feature to analyze the performance of your PHP code.
2) **Q: Why does the browser in Zend Studio fail to display anything?**
**A:** There are some issues with Zend Studio on Windows Server 2003, and the main culprit is JExplorer, which doesn't work properly on this operating system. (Refer to [this link](http://support.teamdev.com/thread.jspa?messageID=1841)). However, there is no such issue on Windows XP.
3) **Q: Why can't Zend Studio perform internal debugging?**
**Solution:** Uninstall Zend Studio completely from your machine (it’s best to use an uninstaller tool), then reinstall it. During installation, do not choose to install the "Platform" option; install directly instead.
**Reason:** This issue might be caused by interrupting the installation process after selecting the "Platform" option. Zend Studio has a logging function that records error information.
4) **Q: Why can't I perform server debugging?**
**Solution:** Install Zend Studio Server or Platform.
**Reason:** The studio server or platform is not installed.
5) **Q: After downloading and installing Zend Studio 5.5.0 from the official website, how do I activate it?**
**A:** There are two files:
1. `license_of_studio.txt` - This file contains the serial number for Zend Studio.
2. `zend_guard.zl` - This is the authorization file for Zend Guard.
To register Zend Studio, follow these steps:
1. Open the `license_of_studio.txt` file.
2. Find the line `User:XXXXXX`, where the second part is the registration name. Enter this part into the registration name field.
3. Find the line `License-key:XXXXXXXXXXXXXXXXXXXXXXX`, where the second part is the license key. Enter this part into the license key field.
4. Click "Confirm" to complete the registration.
6) **Q: What are templates in Zend Studio?**
**A:** Templates in Zend Studio are used to quickly write code. You can input a tag, press the Tab key, and the template code will appear in your editor. You can customize these templates by going to Tools -> Preferences -> Templates and making the necessary changes.
7) **Q: What is Zend Core?**
**A:** Zend Core is a free product developed by Zend to help users install PHP more accurately and quickly. By downloading and installing Zend Core, users can go through a semi-graphical installation interface, entering the required information to install PHP. Zend Core replaces the traditional PHP installation process of Configure -> make -> make install, making the installation of PHP simpler and more standardized.
8) **Q: After opening a project and clicking "Start Execution," it directly enters server debugging (premise: no Zend Studio Server or Platform is installed on this machine).**
**Solution:** Set the debugging method to "Internal Debugging" in the Preferences -> Debugging section.
**Reason:** After opening the project, the debugging mode was changed to "Server Debugging."
