Return the result of the PHP expression or variable after the BEE Conversion specified in conversion.  If the argument value is a PHP variable reference, changes by the BEE Conversion (if the BEE Conversion accept pass by reference) will be effective on the PHP variable.  For example:

<?php

$a = 1;

$b = BEE_convert($a, "inc");

printf("a=%d b=%d ", $a, $b);  // a=1 b=2

$x = 1;

$y = BEE_convert(&$x, "inc");

printf("x=%d y=%d ", $x, $y);  // x=2 y=2

?>
