我已经忙了好几个小时,但是我无法让它发挥作用.

SQL

SELECT DATEDIFF(end_time, start_time) as `difference` FROM timeattendance WHERE timeattendance_id = '1484'

start_time =   2012-01-01   12:00:00
end_time =     2012-01-02   13:00:00

差异是25(小时).但我得到的输出是1(天).

我怎样才能获得25小时的输出？

我试图转换像下面的字符:

ë, ä, ï, ö, etc.

对于普通字符,例如:

e, a, i, o, etc.

做这个的最好方式是什么？我尝试过很多东西,比如preg_replace和str_replace.

有人可以帮我吗？

我试过的是:

$ts = array("[À-Å]","Æ","Ç","[È-Ë]","/[Ì-Ï]/","/Ð/","/Ñ/","/[Ò-ÖØ]/","/×/","/[Ù-Ü]/","/[Ý-ß]/","/[à-å]/","/æ/","/ç/","/[è-ë]/","/[ì-ï]/","/ð/","/ñ/","/[ò-öø]/","/÷/","/[ù-ü]/","/[ý-ÿ]/");

$tn = array("A","AE","C","E","I","D","N","O","X","U","Y","a","ae","c","e","i","d","n","o","x","u","y");

$title = preg_replace($ts, $tn, $text);

我一直在忙着一些AJAX代码.我想计算已加载了多少数据,我想用百分比显示它.

我所有预装的信息都在"反馈"中.我可以计算它包含多少DATA(以字节为单位),还可以查看进度吗？就像装载时一样:10kb,20kb,30kb等

我的代码:

function calc(page)
    {
    $('#pageLoad h2').animate({ marginTop : '0px'}, 200);
        $.ajax(
        {
            url:            './pages/page.php',
            type:           'POST',
            data:           'page='+page,
            success:        function( feedback )
            {
                $('#content').html( feedback );
            }                               

        });
    };

抱歉我的英语不好.

鉴于案文:

"Hello, I'm from Hell",
"Hello, I'm from Ell"

和以下SQL子句:

SELECT * FROM table WHERE text LIKE '%ell%'

我得到上面的两个文本,但我不想得到两个文本,因为我在寻找文本"Ell"而不是"Hell"

如果有人知道我的意思,你能帮助我吗？

提前致谢!

更好的例子

就像你想要寻找"大"这个词一样,但它不能成为"更大"或"最大"之类的任何其他词的一部分

$("#profile_bar").mouseover(function(){

    <?php $_SESSION['sessionasdf'] = 'asdf'; ?>

});

你好!我已经忙了一个小时了,但我现在已经死了.有人可以帮助我或给我一个暗示吗？我上面写的功能是否可能？

提前致谢!
