Question

我遵循这个主题，因为我有同样的问题（不能使用命令shell，只需编辑文件主机） - ＆gt; change a value after 24 hours

首先运行SQL

CREATE TABLE `php_cron` (
  `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
  `last_ts` datetime DEFAULT NULL,
  PRIMARY KEY (`id`)
);

INSERT INTO `php_cron` (`id`, `last_ts`) VALUES (1,'2012-08-10 00:00:00');

我的代码

$res1 = mysql_query("SELECT TIME_TO_SEC(TIMEDIFF(NOW(), last_ts)) AS tdif FROM php_cron WHERE id=1");
$dif = mysql_fetch_assoc($dif['tdif']);

if ($dif >= 86400) { //24h

    //following code will run once every 24h

    //update user's page rank
    $sql2 = "UPDATE logs_limitbandwidthtoday SET BandwidthToday = 0"; 
    mysql_query($sql2);

    $sql23 = "UPDATE logs_limitlinktoday SET LimitLink = 0"; 
    mysql_query($sql23);

    $sql24 = "UPDATE logs_limitvipbw SET BandwidthToday = 0"; 
    mysql_query($sql24);

    $sql25 = "UPDATE logs_limitviplink SET LimitLink = 0"; 
    mysql_query($sql25);

    $sql26 = "UPDATE account_vip SET ALLTime = ALLTime - 1 WHERE ALLTime > 0"; 
    mysql_query($sql26);

    //update last execution time
    $sql3 = "UPDATE php_cron SET last_ts = NOW() WHERE id=1";
    mysql_query($sql3);

}

错误 - ＆gt; PHP警告：mysql_fetch_assoc（）期望参数1为资源，在第2行的/ ....中给出null

我不确定此代码是否仍然有效，请给我一个这个问题的答案。非常感谢你！

好的，这应该可以解决问题

$('.toShow .dslc-modules-area:not(:first)').addClass("hide"); 

$( ".links li" ).click(function() {
    $( ".links li" ).siblings().removeClass('active');
    $(this).toggleClass('active');
    var identify=$(this).index();
    $(".toShow .dslc-modules-area:not(:eq(identify))").addClass("hide");
    $(".toShow .dslc-modules-area").eq([identify]).removeClass('hide').toggleClass("showme");
    $('html,body').animate({scrollTop: $(".toShow").offset().top + 0}, 800);

但是由于mysql_ *已经过时并从PHP 7.0中删除，更新的代码应该是这样的

$dif = mysql_fetch_assoc($res1); 
$dif1 = $dif['tdif']; 
if ($dif1 >= 86400) {

其中$ con是您使用数据库进行的连接

$res1 = mysqli_query($con,"SELECT TIME_TO_SEC(TIMEDIFF(NOW(), last_ts)) AS tdif FROM php_cron WHERE id=1");
$dif = mysqli_fetch_assoc($res1); 
$dif1 = $dif['tdif']; 
if ($dif1 >= 86400) {

    //following code will run once every 24h

    //update user's page rank
    $sql2 = "UPDATE logs_limitbandwidthtoday SET BandwidthToday = 0"; 
    mysqli_query($con,$sql2);

    $sql23 = "UPDATE logs_limitlinktoday SET LimitLink = 0"; 
    mysqli_query($sql23);

    $sql24 = "UPDATE logs_limitvipbw SET BandwidthToday = 0"; 
    mysqli_query($con,$sql24);

    $sql25 = "UPDATE logs_limitviplink SET LimitLink = 0"; 
    mysqli_query($con,$sql25);

    $sql26 = "UPDATE account_vip SET ALLTime = ALLTime - 1 WHERE ALLTime > 0"; 
    mysqli_query($con,$sql26);

    //update last execution time
    $sql3 = "UPDATE php_cron SET last_ts = NOW() WHERE id=1";
    mysqli_query($con,$sql3);

}

mysql_fetch_assoc（）期望参数1为resource，null为null
