string sha1 (string $str, [bool $raw_output = false])
DESCRIPTION
Calculates the sha1 hash of $str using the US Secure Hash Algorithm 1.
PARAMETERS
o $str
- The input string.
o $raw_output
- If the optional $raw_output is set to TRUE, then the sha1 digest is instead returned in raw binary format with a length of 20,
otherwise the returned value is a 40-character hexadecimal number.
RETURN VALUES
Returns the sha1 hash as a string.
EXAMPLES
Example #1
A sha1(3) example
<?php
$str = 'apple';

echo "Would you like a green or red apple?";
}
?>
NOTES
Note
Secure password hashing
It is not recommended to use this function to secure passwords, due to the fast nature of this hashing algorithm. See here for
details.
