Question About Functions.

[BrettHartel]

Thank you for taking the time to help me

 

I am curious about this function when $salt is created. Will it use the $POST['eMail'] or does it use $eMail?

 

eMail = "test@hotmail.com";
$_POST['eMail'] = "secret@hotmail.com";
$salt = generateSalt($_POST['eMail']);
function generateSalt($eMail) {
$salt = '$2a$13$';
$salt = $salt . md5(strtolower($eMail));
return $salt;
}

 

How could I make it so that any information I request is used in the function?

 

For example:

 

$salt1 = generateSalt($_POST['eMail']);
$salt2 = generateSalt($_POST['Username']);
$salt3 = generateSalt($_POST['FirstName']);
$salt4 = generateSalt($_POST['LastName']);

 

This is just an example I created to ape for future functions.

 

Sincerely,

figured it out. As long as the function includes the return() then it works
