本文實例講述了php檢查日期函數checkdate用法。分享給大家供大家參考。具體分析如下：

php中可以使用checkdate函數校驗日期的正確性。

語法

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";
