前两天看了这里的一篇帖。。。有JPGRAPH这个东东,觉得它真的非常实用,真的帮我们在图形统计方面省了不少功夫,于是一直在试用,后来看到:

这里时,我那热情没了一大半。。。。这像我这样的菜鸟就只只能用simsun.ttf吗?后来我试着把很多的中文字体的名字改为simsun.ttf,发现大部分的中文都可以正常显示。。。(可能是全部中文),不敢独享,现把使用方法帖出来跟大家一起分享(我想也许已经有很多高手知道方法,那我就在这里献丑了。。).
在使用有文字显示的类时,必须事先使用SetFont方法来设置字体其有三个参数:字体名,字型,大小。目前在中文方面,JPGraph只支持simsun字体,如果要使用那么就要用以下方法添加:
先在jpgraph.php里用:DEFINE ("TTF_DIR","/usr/local/fonts/ttf/");定义好字体的路径(以后就可以把字体放到这里了)
然后在jpgraph.php里找到这行注释“ // Chinese font ”
在其下面用像这样的方法定义:define("FF_SIMFANG",9);(其中为了容易理解,其格式为:使用“FF_”开头加字体名,“9“为该常量的值,只要不和他原来的值相同,哪个数值都没问题的,只要不太大)
现在进行影射:
找到这个注释"// CONSTRUCTOR"(到这里,聪明的你一定知道怎么回事了),在数组里加入类似:
FF_SIMFANG=>array(FS_NORMAL=>'simfang',FS_BOLD=>',FS_ITALIC=>',FS_BOLDITALIC=>'),的项,该数组是有四个项,第一个为标准字体,第二个为粗体,第三个为斜体,第四个是粗斜体。每一项对应一个字体文件,他们的值就是去了扩展名的字体文件名,没有的话就不用填,除了标准以外。
来到这里,一般的英文字体的添加已经完成,但中文就还是被限制了,关键在以下地方:
找到LanguageConv类,即查找“class LanguageConv”
在函数Convert()里“elseif( $aFF === FF_SIMSUN )”这个地方用或(“||”)添加你之前定义的字体名,如”$aFF===FF_SIMFANG“
好,现在你试试,大功告成!!

Arrays 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.

PHP 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.

Tracking 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.

Using 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.

In 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.

The 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.
