            $sLine .= "\0";
            $iLen = strlen($sLine);

复制代码 代码如下:

$aItems = array(
    'chinaisbig',
    'whichisnot',
    'totalyrightforme',
);
$aTable = array(
    'china,is|small',
    'china,big|me',
    'china,is|big,which|not,me',
    'totaly|right,for,me',
);

$oWeight = new ttrie;
$oWeight->newItems($aItems);
$aResult = $oWeight->newTable($aTable);
