How can I determine if a date is between two dates in PHP?
提问by celsowm
I need know if a $paymentDate(31/12/2010) is valid between $contractDateBegin(01/01/2001) and $contractDateEnd(01/01/2012)
我需要知道$paymentDate(31/12/2010) 在$contractDateBegin(01/01/2001) 和$contractDateEnd(01/01/2012)之间是否有效
dd/mm/yyyy FORMAT !
dd/mm/yyyy 格式！

As of PHP 5.3:
从 PHP 5.3 开始：
$paymentDate = DateTime::createFromFormat('d/m/Y', '31/12/2010');
$contractDateBegin = DateTime::createFromFormat('d/m/Y', '01/01/2001');
$contractDateEnd = DateTime::createFromFormat('d/m/Y', '01/01/2012');
if ($paymentDate >= $contractDateBegin && $paymentDate <= $contractDateEnd)
{
echo "is between\n";
}
You may need to adjust the use of <=to <depending on whether or not the dates are exclusive.
您可能需要使用调整<=到<根据日期是否是排他性的。

if they are formatted as YYYYMMDD you can check if $paymentDate > $contractDateBegin and $paymentDate < $contractDateEnd
如果它们的格式为 YYYYMMDD，您可以检查是否 $paymentDate > $contractDateBegin and $paymentDate < $contractDateEnd
This works with any numeric format that has the larger formats first. If you have american dates for example MM/DD/YYYY, it doesn't work.
这适用于首先具有较大格式的任何数字格式。如果您有美国日期，例如 MM/DD/YYYY，则它不起作用。

$test = strtotime($paymentDate);
if ($test >= strtotime($contractDateBegin) && $test <= strtotime($contractDateEnd))
