$query = 'SELECT * FROM table ORDER BY rand() LIMIT 1

但正如你所看到的那样,它只能从表中随机选择,每当我刷新页面时,它都会给我一个新的随机选择.如何让选秀权持续一整天？

提前谢谢< 3 我正在尝试这个：

$query = "SELECT * FROM table ORDER BY rand(" . date("Ymd") . ") LIMIT 1";

但是我收到以下错误：MysqL_fetch_assoc()：提供的参数不是有效的MysqL结果资源.这是被破坏的部分：

$results = MysqL_query($query); 

while($line = MysqL_fetch_assoc($results))

所以……应该看起来像这样,对吧？ (我的意思是,选择每日随机选择？)

$dailyPick = 'SELECT * FROM table ORDER BY rand() LIMIT 1'; 

$cacheKey = 'dailyPick'. date('dmY'); 
if($cache->has($cacheKey)) { 
    $dailyPick = $cache->get($cacheKey); 
} else { 
    // hit database 
    $dailyPick = $cache->save($cacheKey); 
}

我现在正在尝试这个：

$dailyPick = 'SELECT * FROM table ORDER BY rand() LIMIT 1';  

$cacheKey = 'dailyPick'. date('dmY');  
if($cache->has($cacheKey)) {  
    $dailyPick = $cache->get($cacheKey);  
} else {  
    // hit database  
    $dailyPick = $cache->save($cacheKey);  
}

但是,我错了,我在非对象上使用’has’函数.
