   [41] => haval192,5
   [42] => haval224,5
   [43] => haval256,5
)

Example2

Following example demonstrates the usage of the hash_hmac_algo md5 -

<?php
   echo "The hash_hmac of Welcome to Webdesigntutorialz is - ". hash_hmac(
      'md5', 'Welcome to Webdesigntutorialz','anysecretkey'
   );
?>

Output

When the above code is executed, it will produce the following result -
