FPDF stands for "Free PDF". The FPDF class library provides basic PDF creation functions, and its source code and usage rights are free. This article mainly shares with you how to create pdf pages in php, I hope it can help you.

Advantages of PDF format documents

General: PDF documents can be used normally on UNIX and Windows systems.
Security: PDF documents can be set to read-only mode, and passwords and other protection measures can be added.
Beautiful: PDF documents are largely compatible with Chinese encoding and retain the current page layout.
Exquisite: In most cases, generating PDF documents will reduce the file size.

Solve the Chinese garbled problem

Downloading FPDF The Chinese plug-in chinese.php file creates a
PDF_Chinese() object.
Set the page encoding to GB2312 or use the
iconv() function to change the string encoding.

/*示例代码如下*/<?php
    require_once(&#39;fpdf/chinese.php&#39;);    $pdf=new PDF_Chinese(&#39;P&#39;,&#39;mm&#39;,&#39;A4&#39;);    $pdf -> AddGBFont (&#39;GB&#39;,iconv("UTF-8","gbk",&#39;微软雅黑&#39;));  
    $pdf -> AddPage ();  
    $pdf -> SetFont (&#39;GB&#39;, &#39;&#39;, 20);  
    $pdf -> Cell(0,0,iconv("UTF-8","gbk",&#39;你好，世界！&#39;));    $pdf -> Write (5, iconv("UTF-8","gbk",&#39;你好，世界！&#39;));  
    $pdf -> Output();  
?>

Set the header and footer

By overriding the

Header() method and Footer()# in the FPDF class ## Method to set header and footer. <pre class='brush:php;toolbar:false;'><?phprequire_once(&#39;fpdf/chinese.php&#39;);class PDF extends PDF_Chinese{ function Header(){ $this->SetFont(&#39;GB&#39;,&#39;&#39;,10); $this->Write(10,iconv("UTF-8","gbk",&#39;这是页眉！&#39;)); $this->Ln(20); } function Footer(){ $this->SetY(-15); $this->SetFont(&#39;GB&#39;,&#39;&#39;,10); $this->Cell(0,10,iconv("UTF-8","gbk",&#39;这是页脚！&#39;)); } }$pdf=new PDF(&#39;P&#39;,&#39;mm&#39;,&#39;A4&#39;);$pdf -> AddGBFont (&#39;GB&#39;,iconv("UTF-8","gbk",&#39;微软雅黑&#39;)); $pdf -> AddPage (); $pdf -> SetFont (&#39;GB&#39;, &#39;&#39;, 20); $pdf -> Cell(0,0,iconv("UTF-8","gbk",&#39;你好，世界！&#39;));$pdf -> Write (5, iconv("UTF-8","gbk",&#39;你好，世界！&#39;)); $pdf -> Output(); ?></pre>Set/get the position of an element on the page

void setX(float x);    
//设置某元素在页面的X坐标，单位为mm。如x为负数，则表示自页面右端向左的距离。void setY(float y [, boolean resetX]);    
//设置某元素在页面的Y坐标，单位为mm。如y为负数，则表示自页面底部向上的距离。若可选参数resetX为真则重置X坐标。void setXY(float x, float y);  
  //设置某元素在页面的(X,Y)坐标,规则如上，定位Y时不重置X坐标。float getX();   
   //获得某元素当前X坐标。float getY();    
   //获得某元素当前Y坐标。

Output string

void Write(float h, string txt [, mixed link]);/*
    h:定义字符串的行高。
    txt:指定输出字符串。
    link:可选参数，设置链接。
*/

Line break

void Ln([float h]);//h:设置行高，默认值为最后输出的行的高度。

Text output

void MultiCell(float width, float height, string txt, int border, string align, boolean fill);/*
    width:单元格宽度。
    height:单元格高度。
    txt:放置在单元格中的文本。
    border:单元格边框，默认为0。
    align:对齐方式。默认居左，R=居右，C=居中。
    fill:是否颜色填充。默认false。

    * MultiCell()函数是FPDF输出大段文字的主要方法，可自动换行。

Draw a table

Use the

Cell()

function to create cells in a loop and finally form a table. <pre class='brush:php;toolbar:false;'><?phprequire_once(&#39;fpdf/chinese.php&#39;);$pdf = new PDF_Chinese(&#39;P&#39;,&#39;mm&#39;,&#39;A4&#39;);$pdf -> AddGBFont();$pdf -> AddPage();$pdf -> SetFont(&#39;GB&#39;,&#39;&#39;,14);$header = array(&#39;姓名&#39;,&#39;年龄&#39;,&#39;性别&#39;,&#39;工资&#39;);$data = array();$data[0] = array(&#39;小张&#39;,&#39;24&#39;,&#39;男&#39;,&#39;5,000.00&#39;);$data[1] = array(&#39;小王&#39;,&#39;22&#39;,&#39;女&#39;,&#39;4,000.00&#39;);$width = array(40,40,40,40);for($i=0;$i<count($header);$i++){ $pdf -> Cell($width[$i],6,iconv("UTF-8","gbk",$header[$i]),1); }$pdf -> Ln();foreach($data as $row){ $pdf -> Cell($width[0],6,iconv("UTF-8","gbk",$row[0]),1); $pdf -> Cell($width[1],6,iconv("UTF-8","gbk",$row[1]),1); $pdf -> Cell($width[2],6,iconv("UTF-8","gbk",$row[2]),1); $pdf -> Cell($width[3],6,iconv("UTF-8","gbk",$row[3]),1); $pdf -> Ln(); }$pdf -> Output();?></pre>Note
