我的脚本正在删除空格

Question

这是data.txt的一点点"剪切":

(7220, 'Miecz Swiatla Ksiezyca +', 'Miecz Swiatla Ksiezyca +', 1, 0, 0, 2, 32, 1, 16, '', 30000, 100, 7221, 19, 0, 5, 1, 80, 0, 0, 7, 15, 17, 2, 0, 0, 0, 90, 110, 5, 67, 117, -1, -1, -1, -1, -1, -1, 0, 3, -1),

(13, 'µµ+3                    ', 'Miecz +3', 1, 0, 0, 2, 32, 1, 16, '', 100, 0, 14, 4, 0, 15, 1, 0, 0, 0, 7, 22, 0, 0, 0, 0, 0, 15, 19, 13, 15, 21, -1, -1, -1, -1, -1, -1, 0, 1, 0),
(14, 'µµ+4                    ', 'Miecz +4', 1, 0, 0, 2, 32, 1, 16, '', 100, 0, 15, 5, 0, 15, 1, 0, 0, 0, 7, 22, 0, 0, 0, 0, 0, 15, 19, 13, 15, 28, -1, -1, -1, -1, -1, -1, 30, 1, 0),
(15, 'µµ+5                    ', 'Miecz +5', 1, 0, 0, 2, 32, 1, 16, '', 100, 0, 16, 6, 0, 15, 1, 0, 0, 0, 7, 22, 0, 0, 0, 0, 0, 15, 19, 13, 15, 35, -1, -1, -1, -1, -1, -1, 40, 1, 0),
(16, 'µµ+6                    ', 'Miecz +6', 1, 0, 0, 2, 32, 1, 16, '', 100, 0, 17, 7, 0, 15, 1, 0, 0, 0, 7, 22, 0, 0, 0, 0, 0, 15, 19, 13, 15, 42, -1, -1, -1, -1, -1, -1, 50, 1, 0),
(17, 'µµ+7                    ', 'Miecz +7', 1, 0, 0, 2, 32, 1, 16, '', 100, 0, 18, 8, 0, 15, 1, 0, 0, 0, 7, 22, 0, 0, 0, 0, 0, 15, 19, 13, 15, 49, -1, -1, -1, -1, -1, -1, 65, 1, 0),
(18, 'µµ+8                    ', 'Miecz +8', 1, 0, 0, 2, 32, 1, 16, '', 100, 0, 19, 9, 0, 15, 1, 0, 0, 0, 7, 22, 0, 0, 0, 0, 0, 15, 19, 13, 15, 56, -1, -1, -1, -1, -1, -1, 80, 1, 0),
(19, 'µµ+9                    ', 'Miecz +9', 1, 0, 0, 2, 32, 1, 16, '', 2000, 0, 0, 0, 0, 15, 1, 0, 0, 0, 7, 22, 0, 0, 0, 0, 0, 15, 19, 13, 15, 63, -1, -1, -1, -1, -1, -1, 100, 1, 0),

这是我用来生成查询的脚本MySQL:

header('Content-type: text/html; charset=windows-1250');
$data = file("data.txt"); // returns an array of the lines
foreach($data as $key => $val){
    $temp = explode(',', $val);
    $id = substr($temp[0], 1);
    $name = $temp[1];
    $query = 'UPDATE `item_proto`
        SET `name` = ' . $name . '
        WHERE `vnum` = ' . $id . ';';
    echo $query."<Br/>";
}

输出如下:

UPDATE `item_proto` SET `name` = 'Miecz Swiatla Ksiezyca +' WHERE `vnum` = 7220;
UPDATE `item_proto` SET `name` = '?Î?Í?×???Î070905-121713 ' WHERE `vnum` = 2;
UPDATE `item_proto` SET `name` = 'µµ+0 ' WHERE `vnum` = 10;
UPDATE `item_proto` SET `name` = 'µµ+1 ' WHERE `vnum` = 11;
UPDATE `item_proto` SET `name` = 'µµ+2 ' WHERE `vnum` = 12;
UPDATE `item_proto` SET `name` = 'µµ+3 ' WHERE `vnum` = 13;
UPDATE `item_proto` SET `name` = 'µµ+4 ' WHERE `vnum` = 14;
UPDATE `item_proto` SET `name` = 'µµ+5 ' WHERE `vnum` = 15;
UPDATE `item_proto` SET `name` = 'µµ+6 ' WHERE `vnum` = 16;
UPDATE `item_proto` SET `name` = 'µµ+7 ' WHERE `vnum` = 17;
UPDATE `item_proto` SET `name` = 'µµ+8 ' WHERE `vnum` = 18;
UPDATE `item_proto` SET `name` = 'µµ+9 ' WHERE `vnum` = 19;

上面的输出,最后只有一个空格,但脚本正在删除所有其他空格,因为name应该是24个字符数(包括空格).

那么为什么我的脚本会从nameattr 的末尾删除空格呢？

Answer 1

不是.

但是,如果您在Web浏览器中查看这些查询并且没有更改Content-Type text/html,那么您的浏览器就像在HTML中一样折叠空格.

无论是添加header("Content-type: text/plain");到脚本的开始(和交换<br/>用于\n在浏览器),或者只是"查看源文件"看到逐字输出.
