Example1

The following is an example to get all hash_hmac algorithms -

<?php
   print_r(hash_hmac_algos());
?>

Output

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

Array
(
   [0] => md2
   [1] => md4

   [35] => haval160,4
   [36] => haval192,4
   [37] => haval224,4
   [38] => haval256,4
   [39] => haval128,5
   [40] => haval160,5
   [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 -

The hash_hmac of Welcome to Webdesigntutorialz is - e9768f4407dcb22fb99cb6c4449f1067
