I need to generate pdf using dom pdf and php.
I tried this but I get error 500, I have no syntax errors. If I try : $html='Title here' it works. I tried using an external php script and by using file_get_contents() function but it didn’ work. Anybody can help me find a solution to generate the pdf using a php script?

This is my script (dompdf/index.php): 

<?php

include("dompdf_config.inc.php");
include "../config.php";
include("../db/mysql.php");

$pers=$db->sql_fetchrow($db->sql_query('//-----query here--------'));
$inv=$db->sql_fetchrow($db->sql_query('//-----query here--------'));
$cli=$db->sql_fetchrow($db->sql_query('//-----query here--------'));
$proj=$db->sql_fetchrow($db->sql_query('//-----query here--------'));


$total=$db->sql_query('//-----query here--------');

    Your content() function echoes the text. It pushes it to the screen, while you want to catch it in $html.
    Use return instead.

    UPDATE

    In order to catch all query results to one return, you could append them to a variable like this:

    function content() {
// Define the output variable
$output = "";

//Run query
$pers=$db->sql_fetchrow($db->sql_query('select * from clients_persons where person_id='.$_GET["ps"].''));

//Combine query results and html
$output .= $pers['name'];
$output .= " <i>";
$output .= $pers['email'];
$output .= " </i>";

return $output;
}
