Quicky about using unset() in 'return' value

[timmy0320]

I am using session_set_save_handler() to store my sessions in the database and also added a couple more functions for my script so I don't have to use the $_SESSION variable, etc. Yeah, this is a personal choice because I hate using gaudy looking $_SESSION as variables, etc. My code is below for my script functions:

 

<?php
    // create a session.... for the script
    function _create($name, $data) {


        $name = _sql_escape($name);
        $data = _sql_escape($data);

        return $_SESSION[''.$name.''] = $data;
    }

    // read the session... for the script
    function _read($name) {
        $name = _sql_escape($name);
        return $_SESSION[''.$name.''];
    }

    // unset the session... for the script
    function _unset($name) {
        $unset = unset($_SESSION[''.$name.'']);
        return $unset;
    }
?>

 

The read and write work, but the unset() won't work just returning it or placing it in a variable I get this error message:

 

Parse error: syntax error, unexpected T_UNSET

 

When I used:

unset(_read('registered'));

I got:

Fatal error: Can't use method return value in write context 

 

 

Any ideas? I really don't want to use $_SESSION on my pages because to me it just looks like crap. Maybe I have OCD or something lol

you can't unset the function

try this

<php
    function _remove($name) {
        $name = _sql_escape($name);
        unset($_SESSION[''.$name.'']);
    }
?>

 

or try this

<php
unset(_getVar($name));

    function _getVar($name) {
        $name = _sql_escape($name);
        return $$_SESSION[''.$name.''];
    }
?>

 

**untested

change your function to

 

function _unset($name) {

      unset($_SESSION[''.$name.'']);

        return 1;

    }

 

// you cant assign an unset function result to a variable

Ah, I'm retarded. Thanks

Also there is no point in doing ''.$var_name.'' when using variables, just use $varname, eg:

unset($_SESSION[$name]);
