From forosdelweb

We are going to create a class to make the convertion in convertToPDF.php

<?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';     
}

The next step is to create a page in this case 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>Nombre</th> 
        <th>Tipo</th> 
        <th>Imagen</th> 
        <th>Comentario</th> 
        <th>Unidades</th> 
        <th>Precio unidad</th>     
    </tr>     
    <tr> 
        <td>pensandoo</td> 
        <td>icono</td> 
        <td><img src="http://static.forosdelweb.com/fdwtheme/images/smilies/scratchchin.gif"/></td> 
        <td>iconito pensativo</td> 
        <td>3</td> 
        <td>10</td> 
    </tr> 
    <tr> 
        <td>fiesta</td>

        <td>iconito festejando</td> 
        <td>1</td> 
        <td>24</td> 
    </tr> 
    <tr> 
        <td>silbando</td>

        <td>bombilla silbando</td> 
        <td>19</td> 
        <td>50</td> 
    </tr> 
    <tr> 
        <td>no no no</td> 
        <td>icono 2</td> 
        <td><img src="http://static.forosdelweb.com/fdwtheme/images/smilies/negar.gif"/></td> 
        <td>negacion</td>

</form> 

</body> 
</html>

Finally you can have the file for your style style.css

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; 
}

I had this same issue recently and found fpdf to be too complicated when your HTML contains formatted text and images. I had my server admin install Webkit HTML to PDF. It works great.

This package will parse the stylesheet, images, tables, and any other element in the HTML document as if you had opened a web browser using webkit and saved the web page as a PDF.

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;
}
