Check out http://www.php.net/manual/en/function.round.php

<?php

echo round(3.6451895227869, 2);

?>

EDIT Try using this custom function http://www.php.net/manual/en/function.round.php#102641

<?php 
function round_up ( $value, $precision ) { 
    $pow = pow ( 10, $precision ); 
    return ( ceil ( $pow * $value ) + ceil ( $pow * $value - ceil ( $pow * $value ) ) ) / $pow; 
} 

echo round_up(3.63333333333, 2);  // 3.64

?>
