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

checkdate (2, 29, 1900)?print " is Valid":print " is not valid";

echo "\n";

echo "2/29/2000";

checkdate (2, 29, 2000)?print " is Valid":print " is not valid";

echo "\n";

echo "2/29/2100";

checkdate (2, 29, 2100)?print " is Valid":print " is not valid";

echo "\n";

echo "4/30/2008";

checkdate (4, 30, 2008)?print " is Valid":print " is not valid";

echo "\n";

echo "4/31/2008";

checkdate (4, 31, 2008)?print " is Valid":print " is not valid";
