What potential security risks are associated with using the md5 function for password hashing in PHP?

Using the md5 function for password hashing in PHP is not recommended due to its vulnerability to brute force attacks and collision vulnerabilities. It is considered insecure for storing passwords as it can be easily cracked using rainbow tables. To enhance security, it is recommended to use stronger hashing algorithms like bcrypt or Argon2.
