PHP日期對比問題

Question

我想查看日期是否在當月的第一個和最後一個月之間。我試圖將下面的$ dateInfo字符串轉換爲日期，所以我可以比較這些值...我該如何實現這一點？ DateInfo必須採用以下格式。

變量：

$dateInfo = '20150624T14:49:59' 
$dFirst = new DateTime('first day of this month'); 
$dLast = new DateTime('last day of this month'); 

比較：

if(($dateInfo >= $dFirst) && ( $dateInfo<= $dLast)){ 
    echo 'something';} 
} 

Answer 1

嘗試使用DateTime對象：

<?php 
$dateInfo = new DateTime('20150724T14:49:59'); 
$dFirst = new DateTime('first day of this month'); 
$dLast = new DateTime('last day of this month'); 

if (($dateInfo >= $dFirst) && ($dateInfo <= $dLast)) { 
    $string = "%s is between %s and %s"; 
    printf($string, $dateInfo->format('d/M/Y'), $dFirst->format('d/M/Y'), $dLast->format('d/M/Y')); 
}

試試這個：

$dateInfo = strtotime('20150624T14:49:59'); 
$dFirst = strtotime(date('01-m-Y')); // first day of month 
$dLast = strtotime(date('Y-m-t')); // last day of month 

if(($dateInfo >= $dFirst) && ( $dateInfo<= $dLast)){ 
    echo 'something';} 
} 

祝你好運！

Answer 4

您可以DateTime::getTimestamp比較時間戳。

$dateInfo = '20150724T14:49:59'; 

$myDate = new DateTime($dateInfo); 

$dFirst = new DateTime('first day of this month'); 
$dLast = new DateTime('last day of this month'); 

$occursThisMonth = $dFirst->getTimestamp() <= $myDate->getTimestamp() && 
        $myDate->getTimestamp() <= $dLast->getTimestamp();
