Pull request overview

This PR standardizes calls to global PHP functions/constants by importing them with use function / use const, avoiding fully-qualified references and namespace fallback resolution in the library and its tests.

Changes:

• Import frequently used global PHP functions in test files (session_*, sprintf, urlencode).
• Import global PHP functions/constants in src/PhpInfo.php and switch default flags from \INFO_ALL to INFO_ALL via use const INFO_ALL.
• Import global functions in src/SensitiveValueSanitizer.php and switch \session_name() to session_name() via use function session_name.
