1、要安装java jdk,安装tomcat
2、安装好apache,php
3、下载php-java-bridge_5.5.4_documentation.zip
4、解压缩php-java-bridge_5.5.4_documentation.zip
5、将解压缩后根目录下JavaBridge.war拷贝到tomcat服务器的webapp目录下
6、启动tomcat服务器
7、在php中使用java只需增加下面一行语句:
可以了:
echo $date->getDate();
?>
运行通过,OK!
调用自己的类,先 打包成jar文件 ,运行中写:jar cf Test.jar Test.java。放到tomcat发布目录WEB-INF/lib下.
Test.java如下:
public class Test {
public String rsStr;
public static void main(String[] args)
{
System.out.println("Hello World!");
}
public void setString( String param ){
if( param.equals("") ) {
rsStr = "Hello,how are you!";
}else{
rsStr = param;
}
}
public String getString(){
return rsStr;
}
}
调用的php文件如下:
$t = new java("Test");
echo get_class($t);
$t->setString("ffffffffffff");
echo $t->getString();
//echo "ddjsa;fjsjf;sja;fl";
$t->setString("dddddddddddddddd");
echo $t->getString();
$t->setString("33333333333333333333");
echo $t->getString();
//*******************************my jar
$t1 = new java("IndexTest");
print($t1->searchWord("city","上海","E:\\workspace\\tuan800"));
?>
调用自定义类中包含import的要打包jar:eclipse的export的jar file功能,选中要打包的类所在的项目。打包后将其放到tomcat发布目录的WEB-INF/lib下。
但是lucene换成3.0.0版的时候,打包就只用打类,lucene的核心包直接拷贝到tomcat发布目录的WEB-INF/lib下。
正常调用即可。

Session regeneration refers to generating a new session ID and invalidating the old ID when the user performs sensitive operations in case of session fixed attacks. The implementation steps include: 1. Detect sensitive operations, 2. Generate new session ID, 3. Destroy old session ID, 4. Update user-side session information.

PHP sessions have a significant impact on application performance. Optimization methods include: 1. Use a database to store session data to improve response speed; 2. Reduce the use of session data and only store necessary information; 3. Use a non-blocking session processor to improve concurrency capabilities; 4. Adjust the session expiration time to balance user experience and server burden; 5. Use persistent sessions to reduce the number of data read and write times.

The security of PHP sessions can be achieved through the following measures: 1. Use session_regenerate_id() to regenerate the session ID when the user logs in or is an important operation. 2. Encrypt the transmission session ID through the HTTPS protocol. 3. Use session_save_path() to specify the secure directory to store session data and set permissions correctly.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
