推荐答案

以下代码将图像调整为所需大小.

The following code will resize the images to the size you want.

<?php
$height = 150;
$width = 150;
    function scrape_insta_hash($tag) {
            $insta_source =
        file_get_contents('https://www.instagram.com/explore/tags/'.$tag.'/');
            $shards = explode('window._sharedData = ', $insta_source);
            $insta_json = explode(';</script>', $shards[1]);
            $insta_array = json_decode($insta_json[0], TRUE);
            return $insta_array;
        }

            $tag = 'savesripada';
            $results_array = scrape_insta_hash($tag);
            $limit = 15;
            $image_array= array();
            for ($i=0; $i < $limit; $i++) {

                $latest_array = $results_array['entry_data']['TagPage'][0]['graphql']['hashtag']['edge_hashtag_to_media']['edges'][$i]['node'];
                $image_data  = '<img height="'.$height.'" width="'.$width.'" src="'.$latest_array['thumbnail_src'].'">';
                array_push($image_array, $image_data);
            }


            foreach ($image_array as $image) {
                echo $image;
            }
?>
