Backend DevelopmentPHP TutorialComparison of configuration similarities and differences between php4 and php5_PHP TutorialComparison of configuration similarities and differences between php4 and php5_PHP Tutorial
In the process of configuring php4 or php5, the configuration steps of php4 and 5 are roughly the same, but there are some differences in the configuration content. When compiling in environments such as LINUX, generally speaking, as long as the compilation options are correct, the configuration will be correct; when configuring in Windows, you need to pay attention to the following differences: 1. The files php4ts.dll and php5ts.dll must be copied to the bin of apache. directory or system directory 2. Examples of modules loaded by the httpd.conf file are as follows: # For PHP4 + apache1.x.xx LoadModule php4_module d:/www/webserver/php4/sapi/php4apache.dll AddType application/x-httpd- php .php # For PHP4 + apache2.x.xx LoadModule php4_module d:/www/webserver/php4/sapi/php4apache2.dll AddType application/x-httpd-php .php # Where d:/www/webserver/php4 is php directory. # For PHP5 + apache1.x.xx LoadModule php5_module d:/www/webserver/php5/php5apache.dll AddType application/x-httpd-php .php # For PHP5 + apache2.x.xx LoadModule php5_module d:/www/webserver /php5/php5apache2.dll AddType application/x-httpd-php .php # Where d:/www/webserver/php5 is the directory where php is located. 3. The way to load mysql is different. In php4 and previous versions, mysql is integrated in php; in PHP5 (including BETA) version, mysql is loaded as a module, and php.ini needs to be set to load, such as extension_dir. = "D:/www/WebServer/PHP5/ext/" extension=php_mysql.dll In addition, PHP4 and PHP5 require the support of libmysql.dll in the system directory. If the version is incorrect, even if you set the correct extension_dir and php_mysql. The parameters of dll will also cause the error that phpp_mysql.dll cannot be found when apache starts. Everyone is welcome to discuss and correct me.

Dependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AMYou should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AMSelect DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

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),
