php runs under iis in fastCGI mode, and encountered file system permission problems and solutions.
Today I am going to run a php demo under IIS. The website is The configuration under IIS is as follows:
The application pool is in integrated mode .net framework 2.0 (2.0 or 4.0 does not matter, because php runs in fastCGI mode), and the application pool identifier is configured as the built-in IIS NETWORKSERVICE, the authentication method used is anonymous authentication.
When I opened the local website and accessed the php page, a 500 error occurred.
Okay, it’s a permissions issue. The simplest solution is to set the permissions of C:UsersAdministratorPhpstormProjectsphpDemo to Everyone, and allow full control:
Revisited the php page and succeeded:
The above method is simple enough, but it is also too unsafe. It is usually no problem to set up a local demo to do this, but when it is actually online, it will cause problems sooner or later.
So I reset it and gave the read-only permissions in the directory to the NETWRORKSERVICE account and tried again
However, the problem is still not solved. When accessing, a 401 error occurred
The error message includes that the logged-in user is anonymous. Check the authentication under the website (then click Anonymous Authentication->Edit). It turns out that by default, the website uses the default login user when the login method is anonymous. For IUSR (the anonymous login user we see)
Then the solution is:
1. Set IUSR to the read permission of C:UsersAdministratorPhpstormProjectsphpDemo, similar to the previous setting of NETWORKSERVICE.
2. Or choose to use the application pool identity.
After testing, both methods 1 and 2 were successful.
Note: NETWORKSERVICE belongs to the iis_iusers user group in IIS7. The previous settings for NETWORKSERVICE can also be changed to the settings for iis_iusers, which can also solve the problem, but the permissions are further relaxed.

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Explain the match expression (PHP 8 ) and how it differs from switch.
Apr 06, 2025 am 12:03 AM
In PHP8, match expressions are a new control structure that returns different results based on the value of the expression. 1) It is similar to a switch statement, but returns a value instead of an execution statement block. 2) The match expression is strictly compared (===), which improves security. 3) It avoids possible break omissions in switch statements and enhances the simplicity and readability of the code.

Apr 02, 2025 pm 09:00 PM
Use most text editors to open XML files; if you need a more intuitive tree display, you can use an XML editor, such as Oxygen XML Editor or XMLSpy; if you process XML data in a program, you need to use a programming language (such as Python) and XML libraries (such as xml.etree.ElementTree) to parse.
