php 한글 메뉴얼 도움말 검색 사이트 Verifies that a password matches a hash [function.password-verify]

설명

boolean password_verify ( string $password , string $hash )

Verifies that the given hash matches the given password.

Note that password_hash() returns the algorithm, cost and salt as part of the returned hash. Therefore, all information that's needed to verify the hash is included in it. This allows the verify function to verify the hash without needing separate storage for the salt or algorithm information.

This function is safe against timing attacks.

인수

password: 사용자 패스워드.
hash: password_hash() 함수로 생성한 해시.

반환값

Returns TRUE if the password and hash match, or FALSE otherwise.
