Resize photo that is extracted from a link

Question

I am pulling tweets from a database that include URLs that link to a photo.

I've been able to display the photos on my site but they are just too big.

Here is the code:

foreach ( $entities->media as $media ) {

$tweet_text =str_ireplace($media->url,  '<a href="'.$media->expanded_url.'">'
.$media->display_url.'</a>', $tweet_text);

{
$media_html = '';
$url = $media->media_url_https;
$link = $media->url;
$width = $media->sizes->w;
$height = $media->sizes->h;

  $media_html = "<a href=\"" . $url . "\" target='_blank'>";
  $media_html .=  "<img src=\"" . $url . "\" width=\"" .$width.
     "\" height=\"" .$height. "\" />";
  $media_html .= "</a><br />";          
 $media_html .= $tweet_text;    

    }
return $media_html;

I've tried doing:

$width = $media->sizes->w;
$height = $media->sizes->h;
$width = ($width)/2;
$height = ($height)/2;

but it just isn't displaying after that. I've tried many variations and the only thing I can get to work is if I add

$width = $media->sizes->w+100;
$height = $media->sizes->h+100;

But this just changes the w and h to 100, and as you know, most pictures aren't perfect squares!

What do you all think?

Answer 1

By adding

$RESULT = list($width, $height) = getimagesize($url);

I was able to return the value. It was an array so I couldn't divide the $width or $height without adding that first.

   {
$media_html = '';
$url = $media->media_url_https;
$link = $media->url;
$width = $media->sizes->w;
$height = $media->sizes->h;

$RESULT = list($width, $height) = getimagesize($url);

$width = ($width)/2;
$height = ($height)/2;

  $media_html = "<a href=\"" . $url . "\" target='_blank'>";
  $media_html .=  "<img src=\"" . $url . "\" width=\"" .$width.
  "\" height=\"" .$height. "\" />";
  $media_html .= "</a><br />";          
  $media_html .= $tweet_text;

    }

return $media_html;
