What are the risks of using hashing functions like MD5 for data encryption in PHP?

Using hashing functions like MD5 for data encryption in PHP poses security risks because MD5 is considered cryptographically broken and vulnerable to collision attacks. To improve security, it is recommended to use stronger hashing algorithms like SHA-256 or SHA-512 for data encryption. 

// Using SHA-256 hashing algorithm for data encryption
$data = 'secret_data_to_encrypt';
$encrypted_data = hash('sha256', $data);
echo $encrypted_data;
