Updating or reinstalling the graphics card driver can solve screen flickering problems caused by outdated or damaged drivers; 2. Check and close applications that may cause problems, such as remote desktops, screen recording software, or anti-virus tools with screen filters; 3. Turn off hardware acceleration, including system-level GPU scheduling and hardware acceleration options for browsers and other applications; 4. Adjust display settings to ensure that the resolution is recommended value, scaling adaptation, and check whether the refresh rate is correct; 5. Run the system file checker (sfc/scannow) and the DISM command to repair possible damaged system files; 6. Install the latest Windows updates, including optional driver updates to fix known vulnerabilities; 7. Enter safe mode to test. If the flashing disappears, the problem is caused by software or drivers.

Use the object-fit attribute to make the image fit into the div. It is recommended to use object-fit:cover to make the image fill the container and maintain the proportion. Part of the image may be cropped; if you need to display the image completely, use contain, or use width:100% with height:auto to prevent deformation. You can also set the image as the background to obtain more flexible layout control.

Answer: The clip-path property of CSS is used to define the visible area of ??an element. By creating a specific shape, the content outside the area is invisible, breaking through the limitations of overflow and border-radius that can only achieve rectangular clipping.

JavaScript's # syntax implements the private fields and methods of a class, ensuring that they are only accessible within the class, improving encapsulation and security. 1. Use the # prefix to declare private fields or methods, such as #balance; 2. Private members can only be accessed within the class, and external access will report an error; 3. Support private methods and private getters/setters for internal logic processing; 4. Private fields must be declared in advance and cannot be dynamically created; 5. They are not enumerable and cannot be traversed by Object.keys() or for...in; 6. Subclasses cannot inherit or access private members of the parent class; 7. # is part of the name, and any references need to be retained. This feature enhances the modularity and maintainability of classes.

The global scope is used to add default constraints to all queries of the Eloquent model, such as only getting active users. Define the scope by implementing the Scope interface and overriding the apply method, and then register it in the booted method of the model. The constraint is automatically applied to every query thereafter, including where and find operations. You can temporarily remove specific scopes with withoutGlobalScope, or remove all scopes with withoutGlobalScopes. Avoid overuse, ensure clear naming, concise logic, and prefer local scoping for optional filtering.

First make sure the SOAP extension is enabled, check via php-m|grep-isoap; then load the WSDL file to instantiate the client: $client=newSoapClient('https://example.com/service.wsdl ');, call __getFunctions() to view the available methods, and then call the remote method by passing parameters in the associative array, such as $client->GetUserInfo(['userId'=>123]);; if there is no WSDL, you need to pass null and specify location
