本文實(shí)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(yàn)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(jì)有所幫助。
