In ThinkPHP, if tags and comparison tags compare variables.
In TP template language. Both if and eq can be used to compare variables.
For example:
<if condition=”$id eq 1”>
This is no problem
But if you want to compare two variables:
<if condition=”$a.id eq $b_id”>
This will cause problems
Solution:
Use the
<eq name=”a.id” value=”$b.id”>
Note: There is no need to add the $ variable symbol to the name, but the $ variable symbol is required to the value.

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,
