我只想得到每次入住和退房的第一条记录。该记录包含多个条目，每个ID（如ID 102）有2个签入和2个签出。我只想获取签入的第一条记录和签出的第一条记录。这是我的方法

while (($data = fgetcsv($handle, 1000, ";")) !== FALSE) {
        $num = count($data);
        for ($c=0; $c < $num; $c++) {
            if ($c == 1 || $c == 2 || $c == 3 || $c == 4) {
                if($d != 0){
                    $dtary[$d][$c] = $data[$c] ;
                }
            }
            if ($c == 9 ) {
                $d++ ;
            }
        }
    }

while（（$data=fgetcsv（$handle，1000，；”））！==FALSE）{
$num=计数（$data）；
对于（$c=0；$c<$num；$c++）{
如果（$c==1 | |$c==2 | |$c==3 | |$c==4）{
如果（$d！=0）{
$dtary[$d][$c]=$data[$c]；
}
}
如果（$c==9）{
$d++；
}
}
}
如何设置条件？

您需要
循环
数组并
构建
新的
数组
，如下所示

1st:在循环中存储每个
唯一id的
签入的第一个条目
，然后忽略该id的所有其他
签入条目

2nd:在循环中存储每个
唯一id的
签出的
的
最后一个条目
，因此您只需
覆盖每个条目<代码>如果（$val['4']==“签出”）{..}。

你应该试试

如果约束仅为
ID和“签入/签出”
，而不考虑
日期时间
或每天唯一的
签入/签出
，则签出：

请格式化您的阵列，然后发布您的尝试，让我们看看您已经尝试了什么。我认为它应该是签入的第一个记录和签出的最后一个记录。不是吗？我不能在外面格式化。它是由指纹机生成的。我需要在php脚本中格式化。你说它是多维数组。这就是为什么我要求你格式化数组。谢谢兄弟，这非常有效。你能给我解释一些代码，以便我将来可以修改或修改。谢谢。答案已经更新并添加了一些注释。
