本文實例講述了php實現的日歷程序。分享給大家供大家參考。具體如下:
<?php ////判斷$Year和$Month是否為空,如果為空就獲取系統當前日期,否則用$_GET獲取 $Year = empty($_GET['Year']) ? date("Y"): $_GET["Year"]; $Month = empty($_GET['Month']) ? date("m"): $_GET["Month"]; ////獲取當前日期//// $Today = date("Ymj"); ////初始化日期數組//// $Maxday = array("1","2","3","4","5","6","7","8","9","10","11","12","13","14","15","16","17","18","19","20", "21","22","23","24","25","26","27","28","29","30","31"); $Maxday_count = count($Maxday); ////初始化星期數組//// $Weekday = array("<font color='red'>Sun</font>","Mon","Tue","Wed","Thu","Fri","<font color='red'>Sat</font>"); $Weekday_count = count($Weekday); $daynum = 0; $space = "<td> </td>"; $col = 0; ////打印表格頭部//// ?> <form action="calendar.php" method="post" name="linked"> <table><tr><td colspan=3 align=center><a href="?Year=<?php if($Year-1 > 1900)echo $Year-1;else echo $Year;?>&Month=<?php echo $Month?>" onClick="javascript:document.linked.submit();" name="Year"><<</a> <?php echo $Year?> <a href="?Year=<?php if($Year+1 <2999) echo $Year+1;else echo $Year;?>&Month=<?php echo $Month?>" onClick="javascript:document.linked.submit();" name="Year">>></a></td> <td> </td><td colspan=3 align=center><a href="?Year=<?php echo $Year?>&Month=<?php if($Month-1 >0) if($Month-1 < 10)echo "0".($Month-1); else echo $Month-1; else echo $Month;?>" onClick="javascript:document.linked.submit();" name="Month"><<</a> <?php echo $Month;?> <a href="?Year=<?php echo $Year?>&Month=<?php if($Month+1 <13) if($Month+1 <10) echo "0".($Month+1);else echo ($Month+1); else echo $Month;?>" onClick="javascript:document.linked.submit();" name="Month">>></a></td></tr><tr><td colspan="8"></td></tr><tr> <?php ////打印星期列表//// while(list(,$Weekvalue) = each($Weekday)) echo "<td align=center> ".$Weekvalue." </td>"; echo "</tr>"; ////打印日期列表//// //當月份為4,6,9,11的時候,從數組末尾刪除一個值,也就是刪除31這個值. if($Month == 4 or $Month == 6 or $Month == 9 or $Month == 11) { array_pop($Maxday); $Maxday_count--; } //先判斷月份是否為2月,如果是的話再判斷年份是否為閏年,如果是的話就從數組尾部移除2個值,否則就移除3個值. if($Month == 2) { if($Year % 4 == 0) { array_pop($Maxday); array_pop($Maxday); $Maxday_count-=2; } else { array_pop($Maxday); array_pop($Maxday); array_pop($Maxday); $Maxday_count-=3; } } ////打印日期//// while($daynum < $Maxday_count) { echo "<tr>"; while(list($colnum,$Dayvalue) = each($Maxday)) { //判斷當前日期為一星期中的哪一天 $DayWeek = date("w",strtotime($Year."-".$Month."-".$Dayvalue)); //當當前日期處於第1個,也就是每個月的第1天的時候,在它前面補上相應的空格子 if($Dayvalue == 1) for($i=0;$i<$DayWeek;$i++) echo $space;//打印每個月空出的幾個格子 $daynum++; //當打印日期的時候與當前日期字符串進行比較,如果相等就將字體標為紅色. if($Year.$Month.$Dayvalue == $Today) { $u1 = "<b><u>"; $u2 = "</b></u>"; } else { $u1 = ""; $u2 = ""; } if($DayWeek == 0 or $DayWeek == 6) $color = "red"; else $color = "black"; echo "<td align=center><font color=".$color."> ".$u1.$Dayvalue.$u2." </font></td>"; //用本周第幾天這個值加1,如果是7的倍數就換行退出此輪循環(換行打印) if(($DayWeek+1) % 7 == 0) { $col++; break; } } echo "</tr>"; } ?>
運行效果如下:
希望本文所述對大家的php程序設計有所幫助。
