[RESOLVED] PHP Foreach Error! Pls Help!

[Miteshsach86]

Hi Guys,

I really hope one of you clever genious's can help me. Below is a code which I derived myself, it basically opens up the amazon website on to the page, scrapes everything in between the body tags and then it's supposed to filter out everything into <p></p> tags. But I'm getting the following error 😕

Warning: Invalid argument supplied for foreach() in /var/www/vhosts/...scrapeamazon.php on line 13

<?php
$bbc = "http://www.amazon.co.uk/";
preg_match_all('/<body[^>]*>\s*(.*?)\s*<\/body>/is',file_get_contents($bbc), $bbcwebsite);
$bodytags = $bbcwebsite[1];

if(empty($bodytags) || $bodytags == NULL) { 
    $bbcbody = "Nothing here 1!"; } else {
    foreach ($bodytags as $line_num => $link) {
        $bbcbody = $link . "<br />\n";
        preg_match_all('/<p[^>]*>\s*(.*?)\s*<\/p>/is', $bbcbody, $bbcp);
        $pcontent = $bbcp[1] . "<br />\n";
        if(empty($pcontent) || $pcontent == NULL) {
            $bbcptag = "Nothing here 2!"; } else {
            foreach ($pcontent as $line_num => $ptag) {
                $bbcptag .= $ptag . "<br />\n";
            }
        }
    }
}
?>

I would really appreciate someone's help and thank you in advance. 🙂

Well, S.O.P. for chasing bugs is to do some debugging 😉

<?php 
$bbc = "http://www.amazon.co.uk/"; 
preg_match_all('/<body[^>]*>\s*(.*?)\s*<\/body>/is',file_get_contents($bbc), $bbcwebsite); 

//DEBUG:
print_r($bbcwebsite); echo "<br />";

$bodytags = $bbcwebsite[1]; 

//DEBUG:
print_r($bodytags); echo "<br />";

if(empty($bodytags) || $bodytags == NULL) { 
    $bbcbody = "Nothing here 1!"; } else { 
    foreach ($bodytags as $line_num => $link) { 
        $bbcbody = $link . "<br />\n"; 
        preg_match_all('/<p[^>]*>\s*(.*?)\s*<\/p>/is', $bbcbody, $bbcp); 
        $pcontent = $bbcp[1] . "<br />\n"; 
        if(empty($pcontent) || $pcontent == NULL) { 
            $bbcptag = "Nothing here 2!"; } else { 
            foreach ($pcontent as $line_num => $ptag) { 
                $bbcptag .= $ptag . "<br />\n"; 
            } 
        } 
    } 
} 
?>

and so on....
