What are the key considerations for implementing secure password hashing in PHP applications to prevent security vulnerabilities?

To prevent security vulnerabilities in PHP applications, it is crucial to implement secure password hashing techniques. This involves using strong hashing algorithms like bcrypt, salting passwords before hashing, and using a sufficient number of hashing iterations to slow down potential attackers. 

// Secure password hashing with bcrypt
$hashed_password = password_hash($password, PASSWORD_BCRYPT);
