This function can be used to verify hashes created with other functions like crypt(). For example:
<?php
$hash = '$1$toHVx1uW$KIvW9yGZZSU/1YOidHeqJ/';
if (password_verify('rasmuslerdorf', $hash)) {
echo 'Password is valid!';
} else {
echo 'Invalid password.';
}
// Output: Password is valid!
?>

password_verify — Verifies that a password matches a hash
Descrizione
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.

As Vasil Toshkov stated, password_verify() can be used to verify a password created by crypt() or password_hash()
That is because passwords created by password_hash() also use the C crypt sheme
If you want to verify older plain MD5-Hashes you just need to prefix them with $1$
See https://en.wikipedia.org/wiki/Crypt_(C) for more information.
