Spoofchecker::setAllowedChars — Set the set of characters allowed when running checks

説明

public function Spoofchecker::setAllowedChars(string $pattern, int $patternOptions = 0): void

Restricts the characters that are considered acceptable by subsequent checks to the set described by pattern. Any character outside of this set causes Spoofchecker::isSuspicious() to report a result.

パラメータ

pattern
A character set described as a UnicodeSet pattern, that is a regular-expression style character class. It must begin with [ and end with ], for example [a-z0-9].
patternOptions
A bitmask controlling how pattern is interpreted. It must be 0, or Spoofchecker::IGNORE_SPACE on its own or combined with exactly one of Spoofchecker::CASE_INSENSITIVE, Spoofchecker::ADD_CASE_MAPPINGS, or Spoofchecker::SIMPLE_CASE_INSENSITIVE.

戻り値

No value is returned.

エラー / 例外

Throws a ValueError if pattern is not a valid character set pattern, or if patternOptions is not a valid combination of options.
