I have written a function to generate and store a salt data for a
session cookie. I haven't written the MySQL code, so that is absent.
Basically what I am trying to do is make it so that if there is no
value submitted for an argument, I want it to fall back to the
defaults set up in my config.ini file. This file is successfully
parsed into the array "$_SETTINGS". I have no problems doing this. I
get an "Unexpected T_VARIABLE" in the line with the function
definition. I know this means that I've got a variable call in the
wrong place, but I don't know why it thinks it is wrong.
Can you not default to variables in a function? Or am I just writing
it incorrectly? Please enlighten me on this, I'm pretty much stuck.
--CODE SNIPPET--
function create_salt_data($destination =
$_SETTINGS['session.salt_var'], $prefix =
$_SETTINGS['session.salt_prefix'], $crypt_method =
$_SETTINGS['session.salt_crypt']) {
$crypt_command = '$salt_data = ' . $crypt_method . '(uniqid("' .
$prefix . '"));';
//Did compiling the salt together fail? If so, return failure.
if (!eval($crypt_command)) {
return false;
}
// $salt_data = $crypted_salt;
if ($destination != 'return') {
$_SESSION[$destination] = $salt_data;
return true;
}
else {
return $salt_data;
}
}
I have worked around it by making the defaults null, and then testing
and replacing them inside the function. It takes more code than I
would like it to, I'm trying to condense my files.
Thanks in advance!
