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.
FPDF class library download
##FPDF class library configuration

- Extract the downloaded compressed file to the project root directory.
- Reference the FPDF class library in the project (code below).

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('fpdf/chinese.php'); $pdf=new PDF_Chinese('P','mm','A4'); $pdf -> AddGBFont ('GB',iconv("UTF-8","gbk",'微软雅黑'));
$pdf -> AddPage ();
$pdf -> SetFont ('GB', '', 20);
$pdf -> Cell(0,0,iconv("UTF-8","gbk",'你好，世界！')); $pdf -> Write (5, iconv("UTF-8","gbk",'你好，世界！'));
$pdf -> Output();
?>Copy after login
Set the header and footer
By overriding the
Header() method and Footer()# in the FPDF class ## Method to set header and footer. <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false;" style="font-size:14px;line-height:22px;"><?phprequire_once(&#39;fpdf/chinese.php&#39;);class PDF extends PDF_Chinese{

} 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><div class="contentsignin">Copy after login</div></div>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。

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

Draw a table
Use the
Cell()
function to create cells in a loop and finally form a table. <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false;" style="font-size:14px;line-height:22px;"><?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);

<ul style="list-style-type: none;" class=" list-paddingleft-2">Some information contains the <li>Open()<p> method of the FPDF class library, but it is not actually included in the class library. Using the <code style="font-size:14px;line-height:22px;padding:4px 2px 0px;">Open() method will cause an error.
When using the FPDF class to generate PDF files, the encoding format should be set to GB2312 (or GB related encoding), otherwise even if the PDF_Chinese class is inherited, it will still be garbled.
