Implement removeClassAttribute method

[DenTray]

Description

What needs to be done?

Implement a method removeClassAttribute(string $className, string $attributeName) which processes a PHP source file containing a class definition and removes all attributes with the given attribute name from the class declaration.

• The method must locate the class by $className.
• If the class is not found, the method should show an error and leave the file unchanged.
• If the class has multiple attributes with the same name, all must be removed.
• If the class has multiple attributes with the same name, in different places (with the class and it's methods), only class-related attributes must be removed.
• Support standard PHP 8 attribute syntax with possible multiple attributes in one #[...] block separated by commas.
• If the class does not have the specified attribute, exit without error and file changes.
• Examples: to remove Fillable attribute on class User declared as #[Fillable([...])] or multiple attributes like #[MyAttribute(1234), MyAttribute(5678)].

Expected Outcome

What is the expected result?

• The PHP source code file is updated with all occurrences of the specified attribute removed from the class declaration of the given class name.
• If no matching class is in the file, report error and no change.
• No errors if attribute is not present, and file remains unchanged.
• Multiple attributes in one attribute block are correctly handled, removing only the named attributes but keeping others.
• The syntax and structure of other code remains intact.

Verification Scenarios

How can this be tested?

• Run removeClassAttribute on a PHP file with a single class having one attribute: verify the attribute is removed.
• Run on a class with multiple attributes including multiple instances of the target attribute: all instances removed, others remain.
• Run on a file without the specified class: verify error reported, file unchanged.
• Run on a class with no matching attribute: verify no error and no file change.
• Run on a class with sevaral same name attributes of the class and method: verify only class-related attributes removed.
• Test attributes declared with multiple attributes per block.
• Ensure output is valid PHP syntax after attribute removal.
• Confirm no debug information or errors in the output.
