How to compare two 24 hour time
提问by Ramprasad
I have two 24-hour time values and want to compare them using PHP.
我有两个 24 小时时间值，想使用 PHP 比较它们。
I have tried the following:
我尝试了以下方法：
$time="00:05:00"; //5 minutes
if($time1<='00:03:00')
{
//do some work
}
else
{
//do something
}
Is this the correct way to compare 2 time values using PHP?
这是使用 PHP 比较 2 个时间值的正确方法吗？

Use the built-in function strtotime():
使用内置函数strtotime()：
$time="00:05:00"; //5 minutes
if(strtotime($time)<=strtotime('00:03:00')) {
//do some work
} else {
//do something
}

Yes, that is correct. You don't need to convert to an integer because 24-hour format is such that the string value is in the exact same order as the numeric.
对，那是正确的。您不需要转换为整数，因为 24 小时格式的字符串值与数字的顺序完全相同。
