我有一个项目,从MYSQL迁移到ORACLE RAC中,数据库为UTF8编码格式,用PHP进行简单连接取出的中文均为问号,百度后发现在进行数据库连接时需要指定连接编码为UTF8,我指定了环境变量,并在测试页打印了PHP中全局环境变量,phpinfo(INFO_ENVIRONMENT),结果就正常了。如果不指定,PHP环境变量页面没显示nls_lang的变量信息,则依旧乱码,现在有什么办法,我有好几十个PHP页面,难道都要手动在开头PUTENV(NLS_LANG)定义一下么。求高手赐招能够在PHP服务运行时就自带环境变量nls_lang的参数。并自动在INFO_ENVIRONMENT显示成功。
补充下,我是centos6.5,已经在.bash_profile中定义了nls_lang。但貌似不起作用。PHP是5.6,WEB服务器是nginx 1.9

ORACLE 没有 utf8 只有 utf-8
你在链接 ORACLE 时就应声明所用字符集
只有 ORACLE 8 及以下,才需要设置环境变量

您说的对,但是有没有办法设置默认字符集,即和JAVA那样不在PHP连接字符串中
$conn = OCI_Logon('orcl','orcl','127.0.0.1/orcl','UTF8');或者putenv("NLS_LANG=american_america,UTF8");
两者都能够正常。我现在就是想和JAVA那样不用事先申明,因为我的TEST.PHP文本就是UTF8格式,数据库也是UTF8格式,应该能够自动匹配吧?
我手动输出系统环境变量nls_lang,结果是空的,
phpinfo(INFO_ENVIRONMENT);
?>
求赐教如何才能在PHP初始化的时候装载系统环境变量,换句话说如何指定PHP的环境变量,bash_profile不起作用。
写成 $conn = OCI_Logon('orcl','orcl','127.0.0.1/orcl','UTF8'); 就那么费事吗?
java 是通过 jdbc 进行数据库操作的,php 是通过客户端的
所以后者要多做一些设置上的事情
额,其实这公司是别的软件公司的产品,原生MYSQL,后来由于公司要求统一用ORACLE RAC数据库,迁移过去的。。好吧我找找他们的数据库连接是写在哪的,自己改下算了。

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

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),

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
