我正在编制一个电话呼叫页面。其中一个functions
我的写作会在选定的时间获取available assistants(saved as assistant_ids)
选择一个随机的,将其从列表中删除,然后更新表格。非常直截了当。
我已经为它编写了代码并且它工作得非常好,但是,这段代码使用了很多函数来完成这个过程。而且我觉得我用右脚搔痒我的左耳!
是否有所有这些代码的快捷方式,以后将为服务器节省大量处理?
$assistants = self::get_avail_assists($table, $this->time);
//Assistants are saved as ids and each one is 18 Char.
//each one separated with a space
$assistants_no = strlen($assistants);
if($assistants_no > 1){
for($i=0; $i<$assistants_no; $i=$i+18){
$assistants_array[$i/18] = substr($assistants,$i,17);
}
}
//select random assistant key
$rand_assistant_key = array_rand($assistants_array);
//retrieve selected assistant
$rand_assistant = $assistants_array[$rand_assistant_key];
//delete selected assistant from list
unset($assistants_array[$rand_assistant_key]);
//clear assistants string
$assistants = "";
//recreate assistants string to update
foreach($assistants_array as $assistant){
$assistants .= $assistant." ";
}
//update database after popping out the random assistant
$sql = "UPDATE ".$table." SET ".
"avail_assists='".$assistants."' ".
"WHERE id='".$this->time."' ".
"LIMIT 1";
mysqli_query($sql,etc...
感谢您的时间!

假设助理重新输入数据库的顺序无关紧要......
$ass_array=explode(" ",$assistants); // space-separated string to array
shuffle($ass_array); // mix it up
$lucky_ass=$ass_array[0]; // save one for whatever usage
unset($ass_array[0]); // remove the one from the group
$leftover_string_of_asses=implode(' ',$ass_array); // convert array to space-separated string
...add sql query
