Php 检查时间字符串是否超出小时数

如果给定时间为

$a=22:15:00

和

$b=03:10:00

如何检查设置为

19:00:00

和

06:59:59

它是从旧的4D数据库迁移数据，因此时间没有时间戳

我是这样想的，但真的不确定

$time = DateTime::createFromFormat('H i s', $a )->format('H:i:s');

if($time  >= "19:00:00") && ($time  <= "06:59:59") {
}

$time=DateTime:：createFromFormat（'his'，$a）->格式（'H:i:s'）；
如果（$time>=“19:00:00”）&（$time您可以将它们转换为时间戳，然后进行比较

$a = '22:15:00';
$b = '03:10:00';
$lower='06:59:59';
$upper='19:00:00';
$ts_a=strtotime(date('Y-m-d').$a);
$ts_b=strtotime(date('Y-m-d').$b);
$ts_lower=strtotime(date('Y-m-d').$lower);
$ts_upper=strtotime(date('Y-m-d').$upper);
if($ts_a<=$ts_upper && $ts_a>=$ts_lower){
    echo $a. " is in range";
}
else{
    echo $a. " is not in range";

}
if($ts_b<=$ts_upper && $ts_b>=$ts_lower){
    echo $b. " is in range";
}
else{
    echo $b. " is not in range";

}

$a='22:15:00'；
$b='03:10:00'；
$lower='06:59:59'；
$upper='19:00:00'；
$ts_a=标准时间（日期（'Y-m-d'）。$a）；
$ts_b=标准时间（日期（'Y-m-d'）。$b）；
$ts_lower=标准时间（日期（'Y-m-d'）。$lower）；
$ts_upper=标准时间（日期（'Y-m-d'）。$upper）；
如果（$ts_a=$ts_更低）{
回声$a“在范围内”；
}
否则{
echo$a“不在范围内”；
}
如果（$ts_b=$ts_更低）{
echo$b.“在范围内”；
}
否则{
echo$b.“不在范围内”；
}

如果您更正了一些语法错误并更改代码实际工作的条件：

<?php
$borders['Top'] = "19:00:00";
$borders['Bottom'] = "06:59:59";

// here's your code packed into a function, so it can be tested:
function checkIfOutside($value, $borders) {
                             // missing : here
    $time = DateTime::createFromFormat('H:i:s', $value )->format('H:i:s'); 
              // this re-format isn't really needed in this case, it might though if you have other formats coming in

             // changed from && to || , removed a )
    if($time  >= $borders['Top'] || $time  <= $borders['Bottom']) {

如果我们假设$a和$b是字符串，strotime应该工作。如果我们假设$a和$b是字符串，strotime应该工作。
