Fix PHPDoc type annotation for validateInteger parameters

This PR fixes a PHPStan error caused by the PHPDoc type annotation added in#56503 for thevalidateInteger() method's$parameters argument.

Problem

The PHPDoc typearray{0: 'strict'} requires the first element to always be present and be the string'strict'. However, the$parameters argument defaults to an empty array[], which causes a PHPStan type mismatch error when the method is called without the strict option.

/** * @param  array{0: 'strict'}  $parameters  // ❌ Requires element 0 to exist */publicfunctionvalidateInteger($attribute,$value,array$parameters = []){if (($parameters[0] ??null) ==='strict') {returnis_int($value);    }returnfilter_var($value,FILTER_VALIDATE_INT) !==false;}

Solution

Changed the PHPDoc type toarray<int, string> to properly reflect that:

• The array can be empty (default case)
• When provided, it contains string values at integer keys
• This aligns with other validation rule parameter types in the codebase

/** * @param  array<int, string>  $parameters  // ✅ Allows empty array */

Benefits

• Eliminates PHPStan errors for projects using strict type checking
• Maintains backward compatibility with existing code
• Consistent with parameter type definitions in other validation methods
