我有一个项目来保存用 php 动态创建的页面并将它们存储在服务器上。
我打算将页面的副本存储为 pdf;他们所有的图像、表格和布局。
我尝试使用这些工具:
但老实说,我认为它不会走上正轨
有什么解决方案或者这些工具可以解决这个问题吗?
我最近遇到了同样的问题,当您的 HTML 包含格式化的文本和图像时,我发现 fpdf 太复杂了。我让我的服务器管理员将 Webkit HTML 安装为 PDF。它工作得很好。
这个包将解析 HTML 文档中的样式表、图像、表格和任何其他元素,就像您使用 webkit 打开 Web 浏览器并将网页保存为 PDF 一样。
http://code.google.com/p/wkhtmltopdf/
/**
* Use wkhtmltopdf to convert an HTML file to PDF
*
* @param string URL to web page
* @param string Path to PDF file to be written
*
* @return boolean True if the command succeeded; false otherwise
*/
function htmlToPdf($source, $dest)
{
// Build command
$command = "/usr/bin/wkhtmltopdf $source $dest 2>&1";
exec($command, $output);
$s = sizeof($output) - 1;
if (substr($output[$s], -4, 4) == 'Done')
{
return true;
}
return false;
}
我们将创建一个类来在 convertToPDF.php 中进行转换
<?php
/*----------------------------------------------------------/*
$path : name of the file pdf (without the extension)
i.e.: --> 'ejemplo' , 'pdfs/nuevo-ejemplo'
if empty --> it will be random
$content : content of the pdf
$body : true or false.
true --> add; <doctype>, <body>, <head> to $content
false --> do not alter the $content
$style : the path of the CSS. It could be empty
To load the css --> needs $body = true;
$mode : true or false.
true --> save the file on the server and then show it
false --> ask where to save it
$paper_1 : size of the paper[*]
$paper_2 : style of the paper[*]
[*] To see more options:
--> http://code.google.com/p/dompdf/wiki/Usage#Invoking_dompdf_via_the_command_line
/*----------------------------------------------------------*/
require_once("dompdf/dompdf_config.inc.php");
function doPDF($path='',$content='',$body=false,$style='',$mode=false,$paper_1='a4',$paper_2='portrait')
{
if( $body!=true and $body!=false ) $body=false;
if( $mode!=true and $mode!=false ) $mode=false;
if( $body == true )
{
$content='
<!doctype html>
<html>
<head>
<link rel="stylesheet" href="'.$style.'" type="text/css" />
</head>
<body>'
.$content.
'</body>
</html>';
}
if( $content!='' )
{
//Añadimos la extensión del archivo. Si está vacío el nombre lo creamos
$path!='' ? $path .='.pdf' : $path = crearNombre(10);
//Las opciones del papel del PDF. Si no existen se asignan las siguientes:[*]
if( $paper_1=='' ) $paper_1='a4';
if( $paper_2=='' ) $paper_2='portrait';
$dompdf = new DOMPDF();
$dompdf -> set_paper($paper_1,$paper_2);
$dompdf -> load_html(utf8_encode($content));
//ini_set("memory_limit","32M"); //opcional
$dompdf -> render();
//Creamos el pdf
if($mode==false)
$dompdf->stream($path);
//Lo guardamos en un directorio y lo mostramos
if($mode==true)
if( file_put_contents($path, $dompdf->output()) ) header('Location: '.$path);
}
}
function crearNombre($length)
{
if( ! isset($length) or ! is_numeric($length) ) $length=6;
$str = "0123456789abcdefghijklmnopqrstuvwxyz";
$path = '';
for($i=1 ; $i<$length ; $i++)
$path .= $str{rand(0,strlen($str)-1)};
return $path.'_'.date("d-m-Y_H-i-s").'.pdf';
}
下一步是在这种情况下创建一个页面 index.php
<?php
include('convertToPDF.php');
//$html= --> Aquí pondriamos por ejemplo la consulta
$html='
<img src="http://pxd.me/dompdf/www/images/title.gif"/>
<table>
<tr>

<th>Tipo</th>
<th>Imagen</th>
<th>Comentario</th>

<th>Precio unidad</th>

doPDF('ejemplo',$html,false);

最后你可以拥有你的风格 style.css 的文件
body{
font:12px Arial, Tahoma, Verdana, Helvetica, sans-serif;
background-color:#BECEDC;
color:#000;
}
a h1{
font-size:35px;
color:#FFF;
}
h2{
color:#FC0;
font-size:15px;
}
table{
width:100%;
height:auto;
margin:10px 0 10px 0;
border-collapse:collapse;
text-align:center;
background-color:#365985;
color:#FFF;
}
table td,th{
border:1px solid black;
}
table th{
color:#FC0;
}
.menu{
background-color:#69C;
color:#FFF;
}
.menu a{
color:#FFF;
}
