如下圖:

寫(xiě)個(gè)腳本把剛才保存的data.txt按這個(gè)思路處理一下

$data   = http://www.chinaznyj.com//GuoNeiZiXun/array();$i      = 0;$ret    = '';$handle = @fopen("data.txt", "r");while (!feof($handle)) {    $data[$i] = fgets($handle, 100);    $i++;}fclose($handle);foreach ($data as $data) {    $arr = explode("\t", $data);    if ($arr[0] == "1") {        if ($arr[1] > 150) { //150應(yīng)該足夠分辨50和200了            $ret .= "1";        } else {            $ret .= "0";        }    }}echo "len:"strlen($ret)."\n".$ret;

得到數(shù)據(jù)：

>len:256

>1010110000001110010101000101000000101101010011000100100101001110010010110101111101000011001100110011001001000001010001000100010100001000001100010011000100110001001100010011000100110001001100010011000111000000101010000000000110001001001000101010000000000001

這次看起來(lái)就正常多了。數(shù)據(jù)長(zhǎng)度是256正好可以被8整除，8位一行分割一下得到
