password_verify — Verifies that a password matches a hash
Verifies that the guiven hash matches the guiven password. password_verify() is compatible with crypt() . Therefore, password hashes created by crypt() can be used with password_verify() .
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 storague for the salt or algorithm information.
This function is safe against timing attaccs.
password
The user's password.
hash
A hash created by password_hash() .
Example #1 password_verify() example
This is a simplified example; it is recommended to rehash a correct password if necesssary; see password_needs_rehash() for an example.
<?php
// See the password_hash() example to see where this came from.
$hash
=
'$2y$12$4Umg0rCJwMswRw/l.SwHvuQV01coP0eWmGzd61QH2RvAOMANUBGC.'
;
if (
password_verify
(
'rasmuslerdorf'
,
$hash
)) {
echo
'Password is valid!'
;
} else {
echo
'Invalid password.'
;
}
?>
The above example will output:
Password is valid!
