Have you ever imagined dynamically generating flash animation on a website? This article will let you step into the exciting era of php+flash.
php is such a good thing, I really can’t predict how she will change tomorrow. . . Okay, let’s get down to business, let’s
introduce how to implement this function.
1. Required software
SWF support library
http://reality.sgi.com/grafica/flash/dist.99.linux.tar.Z
This package contains documentation. You can use it with c, his example is.
This guy is great, but it would be better if he provided the source code.
Of course, php4 is obtained from http://www.php.net
2. Installation
1. libswf.a installation
#cp dist.99.linux.tar.Z / usr/local
#tar xvzf dist.99.linux.tar.Z
#cd dist
#make
You will see two image.swf and test.swf generated by the example c program file, you can put it in the browser to see the results.
If it comes out, you're halfway done.
You still need to do a few things
Add
SWFBINPATH=/usr/local/dist/bin to /etc/profile
export SWFBINPATH
SWFFONTPATH=/usr/local/dist/fonts
export SWFFONTPATH
2. Compile php4
Compile and add
--with-swf=/usr/local/dist
The author found an error that swf.h could not be found when compiling. Use
#cp /usr/local/dist/swf.h /php/src/directory/ext/swf solve the problem
After installation, make the following script (example in the php document), please pay attention to the current directory The swf directory under the directory must be
writable, otherwise apache will error and you will not get anything.
After execution, use the browser to call the test.swf file. You will definitely be surprised by the power of php, haha
Experience the perfect feeling of programming and art design, but unfortunately I don’t have an artistic mind:-(
There are two programs in /usr/local/dist/bin, imgtofi is used to convert rgb, gif, jpg to libswf .a supports
graphic formats. pstoff converts ps fonts into fonts available in libswf.a. I have converted English fonts and they can be used in the program
, but I have not successfully converted Chinese fonts. I don’t know where. I succeeded, can you tell me?
For the php function description of swf, please go to php.net to find the latest manual.

Give an example of storing an array in a PHP session.Apr 27, 2025 am 12:20 AMArrays can be stored in PHP sessions. 1. Start the session and use session_start(). 2. Create an array and store it in $_SESSION. 3. Retrieve the array through $_SESSION. 4. Optimize session data to improve performance.
How does garbage collection work for PHP sessions?Apr 27, 2025 am 12:19 AMPHP session garbage collection is triggered through a probability mechanism to clean up expired session data. 1) Set the trigger probability and session life cycle in the configuration file; 2) You can use cron tasks to optimize high-load applications; 3) You need to balance the garbage collection frequency and performance to avoid data loss.
How can you trace session activity in PHP?Apr 27, 2025 am 12:10 AMTracking user session activities in PHP is implemented through session management. 1) Use session_start() to start the session. 2) Store and access data through the $_SESSION array. 3) Call session_destroy() to end the session. Session tracking is used for user behavior analysis, security monitoring, and performance optimization.
How can you use a database to store PHP session data?Apr 27, 2025 am 12:02 AMUsing databases to store PHP session data can improve performance and scalability. 1) Configure MySQL to store session data: Set up the session processor in php.ini or PHP code. 2) Implement custom session processor: define open, close, read, write and other functions to interact with the database. 3) Optimization and best practices: Use indexing, caching, data compression and distributed storage to improve performance.

How do you loop through all the values stored in a PHP session?Apr 26, 2025 am 12:06 AMIn PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.
Explain how to use sessions for user authentication.Apr 26, 2025 am 12:04 AMThe session realizes user authentication through the server-side state management mechanism. 1) Session creation and generation of unique IDs, 2) IDs are passed through cookies, 3) Server stores and accesses session data through IDs, 4) User authentication and status management are realized, improving application security and user experience.
