php检查日期函数checkdate用法实例,checkdate实例

本文实例讲述了php检查日期函数checkdate用法。分享给大家供大家参考。具体分析如下:

php中可以使用checkdate函数校验日期的正确性。

语法

integer checkdate (int %Month, int $Day, int $Year);

演示代码

<&#63;PHP
echo "2/29/1900";
checkdate (2, 29, 1900)&#63;print " is Valid":print " is not valid";
echo "\n";
echo "2/29/2000";
checkdate (2, 29, 2000)&#63;print " is Valid":print " is not valid";
echo "\n";
echo "2/29/2100";
checkdate (2, 29, 2100)&#63;print " is Valid":print " is not valid";
echo "\n";
echo "4/30/2008";
checkdate (4, 30, 2008)&#63;print " is Valid":print " is not valid";
echo "\n";
echo "4/31/2008";
checkdate (4, 31, 2008)&#63;print " is Valid":print " is not valid";
