User query for php fuzzy queryer
if($keywords){
echo '
Query keywords '.$keywords.' The result is:
';if($users){
echo "
| UID | Gender | Interests | ||
|---|---|---|---|---|
| ".$value['uid']." | ";".$value['sex']." | ";".$value['hobby']." | ";
}else {
echo "No relevant user found";

The above introduces the PHP fuzzy query example code, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.

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.

PHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AMDependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
