Question

I am trying to extract some info from a website using simple_html_dom.

Currently I am using:

foreach ($html->find('div.product') as $results) {
    foreach ($results->find('div.image') as $img) {
        echo $img;
    }
    foreach ($results->find('a.title') as $title) {
        echo $title->plaintext;
    }
    foreach ($results->find('div.price') as $price) {
        echo $price;
    }
}

Which works fine. However I need to be able to echo each variable outside of the foreach loop. If I do that using the above code, only the final result will be displayed, i.e. out of the 10 products I am trying to extract only the 10th will be displayed.

Is there a way I can use an array to store all the results from each foreach loop then echo them out once the overall loop is finished?

Something like this:

foreach ($html->find('div.product') as $results) {
    foreach ($results->find('div.image') as $img) {
        array($img);
    }
    foreach ($results->find('a.title') as $title) {
        array($title->plaintext);
    }
    foreach ($results->find('div.price') as $price) {
        array($price);
    }
}
echo array($img);
echo array($title);
echo array($price);

Sorry if this question is confusing I don't have the best grasp on PHP, especially arrays!

Was it helpful?

Solution

$array_img = array();
$array_title = array();
$array_price = array();
foreach ($html->find('div.product') as $results) {
    foreach ($results->find('div.image') as $img) {
        $array_img[] = $img;
    }
    foreach ($results->find('a.title') as $title) {
        $array_title[]= $title->plaintext;
    }
    foreach ($results->find('div.price') as $price) {
        $array_price[]= $price;
    }
}
echo '<pre>';
print_r($array_img);
print_r($array_title);
print_r($array_price);
echo '</pre>';

OTHER TIPS

$images = array();
foreach ($html->find('div.product') as $results) {
    foreach ($results->find('div.image') as $img) {
        $images[] = $img; // append $img to the $images array
    }
}

var_dump($images);

Do the same for the title and price data as well.

$img = array();
$title = array();
$price = array();
foreach ($html->find('div.product') as $results) {
    $img[] = $results->find('div.image');
    $title[] = $results->find('a.title');
    $price[] = $results->find('div.price');
}

print_r($img);
print_r($title);
print_r($price);

Not sure if I completely understand you question, try the following.

$priceList = $titleList = $imgList = array();

foreach ($html->find('div.product') as $results) {<br/>
    foreach ($results->find('div.image') as $img) {<br/>
        $imgList[] = $img;<br/>
    }<br/>
    foreach ($results->find('a.title') as $title) {<br/>
        titleList[] = $title;<br/>
    }<br/>
    foreach ($results->find('div.price') as $price) {<br/>
        priceList[] = $price;<br/>
    }<br/>
}<br/>
foreach ($imgList as $img) {<br/>
        echo $img;<br/>
}<br/>

And so on...
