求助PHP问题!!

可以啊

比如你的页面是index.php

里边的内容如下

php

if($_GET['mod'] ==1){

}

//依次类推

求助用php或 js编一个类似倒计时的工具.就是实时现显示过去某个时间点到现在的时间间隔,就像倒计

这个东西只有用js来实现,

script?type="text/javascript"?src="js/jquery.min.js"/script

script?type="text/javascript"

function?timer(intDiff){

window.setInterval(function(){

var?day=0,

hour=0,

minute=0,

second=0;//时间默认值??

if(intDiff?0){

$('#day_show').html(day◆"天");

$('#hour_show').html('s?id="h"/s'◆hour◆'时');

$('#minute_show').html('s/s'◆minute◆'分');

$('#second_show').html('s/s'◆second◆'秒');

intDiff--;

},?1000);

}?

$(function(){

timer(intDiff);

});?

/script

求助:用php一次更新10万条记录怎么办

检查下 php.ini 文件中的限制

upload_max_filesize

post_max_size

如果超出你提交的文件大小,就改大一些

改了之后重启 apache!

$sql="select CONCAT('{\"',daima,'\":\"',jiancheng,'\"}') from phpcms_z1_gegu";

$rs=mysql_query($sql);

$arr=array();

while($row=mysql_fetch_array($rs))

{

$arr[]=$row[0];

$arr= implode(',',$arr);

$some=$arr;
