新手日期英文月份如何转为数字求助？

[bw126]

我是初学PHP，现在遇到一个问题，就是我要求设计一个网页输入日期，和其他条目输入并存储到txt文件里面。

我做了个下拉菜单让用户选择输入日期，月份和日是用下拉菜单，年用TXT文本输入。

现在问题是要检查日期的有效性，我用checkdate函数来做，如果输入是全部数字，我可以做到这个功能，但是存储要求是用3位英文存储月份，我不知道该怎么样转换。
代码如下：

<?php
$tourtype = $_POST["tourtype"];
	$mo = $_POST["mo"];
	$day = $_POST["day"];
	$year = $_POST["year"];

if(checkdate((int)$mo, (int)$day, (int)$year))
	{
	$path = "../data";
	umask(0007);
	if (!file_exists($path))
		mkdir($path, 02770);

	$bookings = fopen($path. "/bookings.txt", "a");
	
	
	if (is_writable($path . "/bookings.txt")) {
		if (fwrite($bookings, $tourtype .  "\t ". $mo ."\t ". $day ."\t ". $year ."\r\n")) {
			echo "<p class=\"ok\">Thank you for signing our guest book!</p>"; 
		} else {
			echo "<p class=\"wrong\">Cannot add your name to the guest book.</p>";
		}
	} else {
		echo "<p class=\"wrong\">Cannot write to the file.</p>";
	}
	fclose($bookings);
	}
	else{
	echo "<p class=\"wrong\">The date is unavlidated.</p>";
	}
}

?>

<p><b>Tour Date:</b> 
     <select name = "mo">
     <option value = "1" selscted>Jan
     <option value = "2">Feb
     <option value = "3">Mar
     <option value = "4">Apr
     <option value = "5">May
     <option value = "6">Jun
     <option value = "7">Jul
     <option value = "8">Aug
     <option value = "9">Sep
     <option value = "10">Oct
     <option value = "11">Nov
     <option value = "12">Dec
     </select>

改成

<p><b>Tour Date:</b> 
     <select name = "mo">
     <option value = "Jan" selscted>Jan
     <option value = "Feb">Feb
     <option value = "Mar">Mar
     <option value = "Apr">Apr
     <option value = "May">May
     <option value = "Jun">Jun
     <option value = "Jul">Jul
     <option value = "Aug">Aug
     <option value = "Sep">Sep
     <option value = "Oct">Oct
     <option value = "Nov">Nov
     <option value = "Dec">Dec
     </select>

从数组中取怎么样？

$months=array("","Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec");
$mm=$months[$_POST["mo"]);
$mydate=$mm." ".$dd." ".$yyyy

$months=array("","Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec");
$mydate=$months[$mo]." ".$day." ".$year

$mydate=$months[$mo]." ".$day." ".$year

这个就是我要改的地方了。

还是用下来菜单输入数字的月份，最后转换一下格式写入txt文件就好了，谢谢你。

就是这样的内容，每条存储在文本文件的一行。
