<?php
include_once 'conexao.php';
$myfile = fopen("arquivo.m3u", "w") or die("Impossível abrir o ficheiro!");
$mainline =
"#EXTM3U \n";
fwrite($myfile, $mainline);
$grab = $link->prepare("SELECT * FROM `tb_iptv`");
$grab->execute();
foreach($grab as $p) {
$canal = $p["canal"];
$url = $p["url"];
$tvgid = $p["tvgid"];
$tvgname = $p["tvgname"];
$tvglogo = $p["tvglogo"];
$grupo = $p["grupo"];
$mainline2 ='#EXTINF:-1 tvg-id="'.$tvgid.'" tvg-name="'.$tvgname.'" tvg-logo="'.$tvglogo.'" group-title="'.$grupo.'",'.$canal.'
'.$url.'

fwrite($myfile, $mainline2);
}
