Below i had encrypted a string varible using sha1. And now i would wish to decrypt data using sha1 function, but am going some where. Would some one come forward and guide me in proper way please.
Below is my code
<?php
$variable = "tiger";
echo $variable;
$encrypt = sha1($variable);
echo $encrypt;
$decrypt = sha1($encrypt);
echo $decrypt;
?>
And i get output like this
tiger

SHA-1 is an one-way hash function.
According to wikipedia
A cryptographic hash function is a hash function which is considered practically impossible to invert, that is, to recreate the input data from its hash value alone.

Thus you simply can not decrypt it.
