What are some alternative hashing algorithms to MD5 that can be used for password security in PHP applications?

MD5 is considered to be a weak hashing algorithm for password security due to its susceptibility to collision attacks. To improve password security in PHP applications, it is recommended to use stronger hashing algorithms such as bcrypt or Argon2. These algorithms are specifically designed for password hashing and are resistant to various attacks. 

// Using bcrypt for password hashing
$password = "secret_password";
$hashed_password = password_hash($password, PASSWORD_BCRYPT);

// Verify password
if (password_verify($password, $hashed_password)) {
    echo "Password is correct";
} else {
    echo "Password is incorrect";
}
```

```php
// Using Argon2 for password hashing
$password = "secret_password";
$hashed_password = password_hash($password, PASSWORD_ARGON2I);

// Verify password
if (password_verify($password, $hashed_password)) {
    echo "Password is correct";
} else {
    echo "Password is incorrect";
}
