• HTML Generation: The Html helper simplifies creating HTML elements, adding attributes, and handling potential security risks like Cross-Site Scripting (XSS). Instead of manually constructing HTML strings, developers can use methods like Html::a() , Html::tag() , and Html::encode() for cleaner and safer code.
• Array Manipulation: ArrayHelper provides a robust set of methods for efficiently manipulating arrays. ?? ??, ?? ? ?? ? ??? ?? ?? ??? ?? ??? ?? ???? ?? ?????.
• String Manipulation: StringHelper offers a collection of functions for various string operations, including converting cases, trimming whitespace, and performing substring searches. ??? ? ????? ????? ??? ???? ?? ??? ???? ?? ??? ??? ???? ????.
• URL Management: The Url helper simplifies the process of generating URLs, handling parameters, and creating absolute or relative URLs. ??? ?? URL ?? ?? ??? ???? ?? ? ? ?? ?????.
• File System Operations: FileHelper provides convenient methods for interacting with the file system, including creating directories, copying files, and managing file permissions. ?? ?? ??? ????? ???? ???? ??? ??? ????.
