手把手教你打印出PDF(关于fpdf的简单应用)_php技巧
今天使用的类叫FPDF,FPDF这个PHP Class允许你采用纯PHP(更确切地说就是不需要使用PDFlib)来生成PDF文件。它以PHP Class展现并且加速PDF文档在编程语言中的进程。它所具有的特点包括:可选择的单元大小,页面格式和页边距;页眉和页脚管理;自动分页;自动换行与文本自动对齐等等。 同时它还支持多种图片格式,如JPEG,PNG,TrueType和Type1等等。试用一下你一定不会失望。
1、从网上下载fpdf的类,然后实用require包含进来(附件里也有)。
require('./fpdf/fpdf.php');//包含pdf文件
2、然后我们定义一个数组,数组的内容是今天的奖牌情况
/*
* country,国家
* nationalFlag,国旗
* glod,金牌数量
* silver,银牌数量
* copper,银牌数量
*/
$platle=array(
array('country'=>'PRC','nationalFlag'=>'rpc.jpg','glod'=>27,'silver'=>13,'copper'=>15),
array('country'=>'USA','nationalFlag'=>'usa.jpg','glod'=>25,'silver'=>16,'copper'=>4),
array('country'=>'UK','nationalFlag'=>'uk.jpg','glod'=>14,'silver'=>7,'copper'=>8)
);
3、既然第一步已经包含进类来了,然后咱再自己定义一个类以方便定义自己的内容
class PDF extends FPDF{
/*
* $count,国家
* $nationalFlag,国旗的图片地址
* $imageX,国旗的x坐标
* $imageY,国旗的Y坐标
* $goldTotal,金牌总数
* $silverTotal,银牌总数
* $copperTotal,铜牌总数
*/
function createHead($country,$nationalFlag,$imageX,$imageY,$goldTotal,$silverTotal,$copperTotal){
$this->setFont('Arial','B','24');//定义一个字体及样式
$this->cell(40,20,$country,15);//显示各个国家的信息
$this->image($nationalFlag,$imageX,$imageY);//国旗的位置
$this->setX('70');//设置国旗的坐标
$this->setTextColor(200,160,12);//设置金牌的颜色
$this->cell(40,20,$goldTotal);//显示金牌数量
$this->setX('100');//设置金牌数量的显示位置
$this->setTextColor(170,162,138);//设置银牌的颜色
$this->cell(40,20,$silverTotal);//显示银牌数量
$this->setX('130');//设置银牌数量的显示位置
$this->setTextColor(187,120,68);//设置铜牌的颜色
$this->cell(40,20,$copperTotal);//显示银牌的位置
$this->ln();//进行换行
$this->setTextColor(0,0,0);//因为设置的颜色能在整个页面都有效,所以这里每次输入一个国家的信息就恢复初始的颜色
}
}
使用到的各种方法解释:
1、SetFont(string family [, string style [, float size]])
设定字符串的字型。在文字或整篇文章显示之前,该方法设置的字体在整个PDF文件中都试用。
参数1:family,设定需要的字体。
参数2:style,设定样式。(空字符串代表普通文字,U代表下划线,B代表粗体,I代表斜体)。
参数3:size,字体的大小。
2、Cell(float w [, float h [, string txt]])
显示一个储存格 (长方形范围),同时,也提供其它功能选项,包括(边框、背景颜色、字符串)。储存格左上角的位置为目前位置。
注:该方法中还有其他的参数,没有列出来。因为在该实验中没有用到。
参数1:w储存格宽度。 若为:0,这个储存格会延伸至页的右边边缘。
参数2:储存格高度。默认值为:0.
参数3:txt,要打印出来的内容。
3、Ln([float h])
完成行中断,并且换行。会使到目前的(x,y)坐标改变,横坐标(x)回到去左边边缘,并且将纵坐标(y)高度增加。
参数1:h,下一行的距离或高度。默认值为:高度相等于最后显示的高度。
4、SetTextColor(int r [, int g, int b])
定义文字使用的颜色。可以使用RGB色彩或灰阶模式来定义。这个功能可以在一页之前建立,而且那个色彩值会保留在一页到另一页。
4、类已经定义完了,最后调用一下
$pdf=new PDF();//实例化类
$pdf->AddPage();
$imageX=40;//设置图片的初始X值
$imageY=15;//设置图片的初始Y值
foreach($platle as $key=>$value){
$pdf->createHead($value['country'],$value['nationalFlag'],$imageX,$imageY,$value['glod'],$value['silver'],$value['copper']);
$imageY+=20;
}
$pdf->output();//输出PDF
注:
1、AddPage()方法是用来生成一个新的页面的。每调用一次都生成一个新的页面。
2、outPut()方法是用来输出PDF的。
