农历名称转换类【转载】
今天用到一个公历转换成农历的类，在网上找的的，做了一下修改，现在可以使用了。收藏一下，以后可能还会用到。

PHP合成图是处理有透明背景的图片【原创】
今天在合成图是遇到个问题，背景图片有个透明色的背景，而且是圆角的，这个用普通的画布会出现问题，比如白色的画布，背景图的圆角出就会显得很难看（有个白色的角）
Google了一下，找到了一个方法。见代码：
imagealphablending
此函数，开启或关闭一个真彩色图像资源的混色模式。开启与关闭混合模式有什么区别呢？如果不涉及透明度的问题，两个模式没什么区别，但是如果是在一张画布上画一条透明颜色的线，不同的混合模式将出现不同的效果，如果混合模式开启，则透明线的颜色会与原背景中的颜色叠加，计算出新的颜色，显示出来，如果混合模式关闭，则透明线的颜色直接覆盖到画布中对应位置的颜色值。
简单来说，开启混合模式，颜色叠加，关闭混合模式，颜色覆盖。
imagecolorallocatealpha
类似于拾色器的功能，就是生成一个颜色， 的行为和 imagecolorallocate 相同，但多了一个额外的透明度参数 alpha，其值从 0 到 127。0 表示完全不透明，127 表示完全透明。
imagesavealpha
设置标记以在保存 PNG 图像时保存完整的 alpha 通道信息，如果你想保存一个透明的png图标，这个函数是必要的。
使用JavaScript的JSONP实现跨域访问【原创】
JSON 是用于在浏览器和服务器之间交换信息的轻量级数据格式（与 XML 相比）。JOSON 依赖于 JavaScript 开发人员，因为它是 JavaScript 对象的字符串表示。JSONP广泛应用于跨站调用json数据的API当中。
一般来说位于 server1.example.com 的网页无法与不是 server1.example.com 的服务器沟通，而 HTML 的 <script> 元素是一个例外。利用 <script> 元素的这个开放策略，网页可以得到从其他来源动态产生的 JSON 资料，而这种使用模式就是所谓的 JSONP。
下面看一个JSONP的简单实例吧。
服务器端的脚本实现（PHP）：http://www.test.com/index.php
<?php
header("Content-Type: text/html; charset=UTF-8");
$student_info = array(
'name' => 'fisher',
'sex'=>1,
'age'=>20
);
echo $_GET['callback'] . '(' . json_encode($student_info) . ');';
客户端脚本实现（javascript ）：file:///C:/Users/fisher/Desktop/index.html
<script type="text/javascript">
function studentInfo(data) {
alert(data.name);
}
</script>
<script type="text/javascript" src="http://www.test.com/index.php?callback=studentInfo"></script>
下面是利用JQuery实现的JSONP
JavaScrit的Number()和parseInt()区别【原创】
- 在转换空字符串或null时，Number()会返回0；parseInt()会返回NAN
alert("Number: " + Number(null)); //0
alert("parseInt: " + parseInt(null));//NaN
alert("Number: " + Number(null)); //0
alert("parseInt: " + parseInt(null));//NaN
- 如果前几个字符是数字字符，后面跟着几个非数字字符， parseInt()只会返回前几个数字字符，后面的非数字字符会被忽略；而Number()会返回NAN
alert("parseInt: " + parseInt('123hello'));//123
alert("Number: " + Number('123hello'));//NaN
- 注意：如果是浮点数如："1.23"或1.23,Number()会返回1.23，而parseInt()会返回1，他把小数点当做的非数字字符。
alert("parseInt: " + parseInt(1.23)); //1
alert("Number: " + Number(1.23));//1.23
alert("parseInt: " + parseInt("1.23"));//1
alert("Number: " + Number("1.23"));//1.23
- 如果字符串中的第一个字符是数字字符，parseInt()也能识别出各种正数格式（即十进制，二进制，八进制，十六进制）;对于二进制，八进制Number()则会忽略字符串的前导0，输出后面的数字，对于十六进制，Number()会转换为十进制。
alert("parseInt: " + parseInt('0101')); //65
alert("Number: " + Number('0101'));//101
alert("parseInt: " + parseInt('070')); //56
alert("Number: " + Number('070')); //70
alert("parseInt: " + parseInt('0xf0')); //240
alert("Number: " + Number('0xf0'));//240
