Question

I previously found a script while googling and used it for scrapping purpose, my main class

in my amazon.php, I wrote the following script

include('scrape.php');
set_time_limit(0);


$ASIN       =   'B000GEM3RI';
$shipArray  =   shipingPrice($ASIN);
var_dump($shipArray);
print_r($shipArray);
echo $shipArray;



function shipingPrice($city){
        $shipArray = array();
        $scrape = new Scrape();
        $url = 'http://www.amazon.com/gp/offer-listing/'.$city.'/ref=dp_olp_new?ie=UTF8&condition=new';
        $scrape->fetch($url);
        $data = $scrape->removeNewlines($scrape->result);
        $data = $scrape->fetchBetween('<table cellspacing="0" cellpadding="0" width="100%" border="0"> <thead class="columnheader"><tr><th scope="col" class="price">Price + Shipping</th><th scope="col" class="condition">Condition</th><th scope="col" class="seller">Seller Information</th><th scope="col" class="readytobuy">Buying Options</th></tr></thead>','</table>',$data,true); 
        $rows = $scrape->fetchAllBetween('<tr','</tr>',$data,true);
        $i=0;$j=0;
        foreach ($rows as  $row){
            if($i!=0){
                if($i!=2){              
                    $record = array();
                    $cells = $scrape->fetchAllBetween('<td','</td>',$row,true);                 
                    $record['price'] = strip_tags($cells[0]);
                    
                    if(stristr($record['price'],'oz')===False && stristr($record['price'],'/')===False)
                    {
                        $listPrice=$scrape->fetchBetween('$',' +',$record['price']);
                    }else{
                        $listPrice=$scrape->fetchBetween('$',' (',$record['price']);
                    }
                    //print_r($listPrice);
                    if($listPrice==''){
                        $listPrice=$scrape->fetchBetween('$',' &',$record['price']);
                        $shipPrice='0';                     
                    }else{
                        $shipPrice=$scrape->fetchBetween('+ $','s',$record['price']);
                    }
                    $shipPrice= floatval($shipPrice);
                    //####                  
                    $sellerIdInfo = $cells[2];                                          $sellerIdArray=$scrape->fetchAllBetween('&marketplaceSeller=0&seller=','"><b>',$sellerIdInfo);                  
                    if(count($sellerIdArray)>1){
                        $sellerId=$sellerIdArray[0];
                    }else{
                        $temp = explode('"id',$sellerIdArray[0]);
                        $sellerId=$temp[0];                                         
                    }
                    //##
                    $sellerName =$scrape->fetchBetween('Seller:','Seller',$record['price']);                    
                    $sellerInfo=$scrape->fetchAllBetween('alt="','"',$cells[2],true);           
                    $sellerName=str_replace(array('alt="','"'),array('',''),$sellerInfo[0]);
                    if($sellerName!=""){        
                        //
                    }else{
                        $sellerName = $scrape->fetchBetween('<span class="sellerHeader">Seller:</span>','</b></a>',$cells[2],true);
                        $sellerName=str_replace("Seller:","",$sellerName);
                        $sellerName=$scrape->fetchBetween('<b>','</b>',$sellerName);            
                    }

                    array_push($shipArray,array('sellerName'=>$sellerName,'sellerId'=>$sellerId,'price'=>$listPrice,'shipPrice'=>$shipPrice));

                }
            }
            $i++;
        }
        return $shipArray;
}

the url for this scrip is amazon

when I echo it, var_dump it or print_r, an empty array is displayed, I checked the page using firebug and to me, looks like everything is okay in my code

can somebody tell me why I can access anything from the page although my code is okay?

thanks for helping me

EDIT:-

By adding return $this->result = curl_exec($ch); in my scrap class function fetch($url), I have assured that Page is being retrieved successfullly…

EDIT-2:-

after working on the advice as provided in answer, it tried

$shipArray[]=array('sellerName'=>$sellerName,'sellerId'=>$sellerId,'price'=>$listPrice,'shipPrice'=>$shipPrice); 

in my function, but still the same empty array

EDIT-3

I changed the following function

function fetchBetween($needle1,$needle2,$haystack,$include=false){
        
        $position = strpos($haystack,$needle1);
        
        if ($position === false) { return ' it was null data'; }

when I echo echo $data; in my script file,

it was null data

is printed, so looks like this line of code $position = strpos($haystack,$needle1); is not working,

am I right?

if yes, what to do now?

Answer 1

Gotcha, I was correct, issue was not with my code

on line

 $data = $scrape->fetchBetween('<table cellspacing="0" cellpadding="0" width="100%" border="0"> <thead class="columnheader"><tr><th scope="col" class="price">Price + Shipping</th><th scope="col" class="condition">Condition</th><th scope="col" class="seller">Seller Information</th><th scope="col" class="readytobuy">Buying Options</th></tr></thead>','</table>',$data,true);

there was an extra space border="0"> <thead class, that was creating issue, once, I removed this the space from

<table cellspacing="0" cellpadding="0" width="100%" border="0"><thead class="columnheader">

my code became okay..

thanks to everyone
