Windows 7下PHP配置环境
PHP环境搭建第四步:在Windows 7下如何进行PHP配置环境。
PHP环境在Windows 7上的配置相比Windows XP等要简单很多,不需要复制等操作,你只要将php.ini-development配置文件重命名为php.ini配置文件即可。接着做如下配置操作:
1、打开php.ini配置文件,找到
1
2 |
; On windows:
; extension_dir = "ext" |
修改为
1
2 |
; On windows:
extension_dir = "C:/php/ext" |
表示指定PHP扩展包的具体目录,以便调用相应的DLL文件。
2、由于默认PHP并不支持自动连接Mysql,需开启相应的扩展库功能,比如php_mysql.dll等,即将
1
2 3 4 5 6 7 |
extension=php_curl.dll
extension=php_gd2.dll extension=php_mbstring.dll extension=php_mysql.dll extension=php_pdo_mysql.dll extension=php_pdo_odbc.dll extension=php_xmlrpc.dll |
这些extension之前的分号(;)去除。
3、配置PHP的Session功能
在使用session功能时,我们必须配置session文件在服务器上的保存目录,否则无法使用session,我们需要在Windows 7上新建一个可读写的目录文件夹,此目录最好独立于WEB主程序目录之外,此处我在D盘根目录上建立了phpsessiontmp目录,然后在php.ini配置文件中找到
1
|
;session.save_path = "/tmp"
|
修改为
1
|
session.save_path = "D:/phpsessiontmp"
|
4、配置PHP的文件上传功能?如何编写PHP文件上传功能?
同session一样,在使用PHP文件上传功能时,我们必须要指定一个临时文件夹以完成文件上传功能,否则文件上传功能会失败,我们仍然需要在Windows 7上建立一个可读写的目录文件夹,此处我在D盘根目录上建立了phpfileuploadtmp目录,然后在php.ini配置文件中找到
1
|
;upload_tmp_dir =
|
修改为
1
|
upload_tmp_dir = "D:/phpfileuploadtmp"
|
5、修改date.timezone,否则在执行phpinfo时date部分会报错:
Warning: phpinfo() [function.phpinfo]…
我们需要将
1
|
;date.timezone =
|
修改为
1
|
date.timezone = Asia/Shanghai
|

至此在Windows 7上php的环境配置就算完成了,但是光完成这些配置是不够的,我们需要Apache支持PHP,所以还需要在Apache配置文件中完成相应的PHP配置。
PHP环境搭建第五步:配置Apache以支持PHP
1、在#LoadModule vhost_alias_module modules/mod_vhost_alias.so下添加
1
2 3 |
LoadModule php5_module "c:/php/php5apache2_2.dll"
PHPIniDir "c:/php" AddType application/x-httpd-php .php .html .htm |
我们在PHP目录下可以看到多个php5apache的DLL文件,由于我们使用的是Apache2.2.15,所以我们当然需要使用php5apache2_2.dll,接着指定PHP的安装目录以及执行的程序扩展名。
2、我们应该知道默认Apache服务器执行WEB主程序的目录为Apache2.2/htdocs,所以当你的WEB主程序目录变更时,我们需要修改相应的Apache配置,即将
1
|
DocumentRoot "C:/Program Files/Apache Software Foundation/Apache2.2/htdocs"
|
修改为
1
|
DocumentRoot "D:/PHPWeb"
|
1
|
|
修改为
1
|
|
3、最后修改具体的index文件先后顺序,由于配置了PHP功能,当然需要index.php优先执行
1
|
DirectoryIndex index.html
|
修改为
1
|
DirectoryIndex index.php index.html
|
4、重启Apache服务器
至此,在Apache服务器上PHP环境配置工作就完成了,你只需要在D:/PHPWeb目录下新建一个PHP文件,写入
1
2 3 |
phpinfo(); ?> |
然后在游览器中输入http://localhost,就可以看到PHP的具体配置页面了,代表在Window 7上PHP环境配置工作就算完成了。

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),
