And if it is not the right method then please tell me how I can access a variable from one method to another in the controller My Variable is $variable and the function is:

`public function date_to_db($ui_date){
   $temp = explode('/', $ui_date);

return $db_date; }`

Answer 1

You can use

$variable = 'test';

function test()
{
    global $variable;

    $value = $variable;

    return $value;  

}

or add an index to the global array $GLOBALS['var'] = 'test';
