本文實例講述了php檢查日期函數(shù)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(shù)校驗日期的正確性。

語法

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

演示代碼

<?PHP

echo "2/29/1900";

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";

echo "\n";

?>

輸出結(jié)果如下

2/29/1900 is not valid

2/29/2000 is Valid

2/29/2100 is not valid

4/30/2008 is Valid

4/31/2008 is not valid

希望本文所述對大家的php程序設(shè)計有所幫助。
