php - 检查空值 PHP 代码更短

Question

有没有办法做到这一点，但以更短的方式？还是“更专业”的方式？感谢致敬。检查变量是否为空(检查是否为空)。

if((
empty($varone) || 
empty($vartwo) || 
empty($vthree) || 
empty($vardf) || 
empty($vfgsdgsdal) || 
empty($pasadfsd) || 
empty($efda) 
)) {
    $response = "There is an empty data";
    }else{$response = "NO EMPTY DATA!";}

Answer 1

第一个解决方案，在数组中添加值并测试是否有空值

function checkEmptyValueArray($values) {
    return !empty(array_filter($values, function ($value) {
        return empty($value);
    }));
}

$values = [$varone, $vartwo, $vthree, $vardf, $vfgsdgsdal, $pasadfsd, $efda];

if ( checkEmptyValueArray($values) ) {
    $response = "There is an empty data";
} else{
    $response = "NO EMPTY DATA!";
}

另一种解决方案是使用可变长度参数列表

function checkEmptyValueArray(...$args) {
    foreach ( $args as $arg ) {
        if ( empty($arg) ) {
            return true;
        }
    }
    return false;
}

if ( checkEmptyValueArray($varone, $vartwo, $vthree, $vardf, $vfgsdgsdal, $pasadfsd, $efda) ) {
    $response = "There is an empty data";
} else{
    $response = "NO EMPTY DATA!";
}
