I wrote this a while ago to resize images smaller. It will not resize larger. It will keep the same aspect ratio and make sure the image is smaller than the given width and height (if you give both, you don't need to).

function resize_image($opts){  $src = isset($opts['source']) ? $opts['source'] : '';  $dest = isset($opts['dest']) ? $opts['dest'] : '';  $w = isset($opts['w']) ? intval($opts['w']) : 0;  $h = isset($opts['h']) ? intval($opts['h']) : 0;  if ($src == '')  {    return;  }  if ($w == 0 && $h == 0)  {    return;  }  if ($dest == '')    $dest = $src; // resize in place  // open the image  $ext = strtolower(array_pop(explode('.', $src)));  switch ($ext)  {    case 'jpg':    case 'jpeg':      $i = imagecreatefromjpeg($src);    break;    case 'gif':      $i = imagecreatefromgif($src);    break;    case 'png':      $i = imagecreatefrompng($src);    break;    default:      return;  }  $new_w = imagesx($i);  $new_h = imagesy($i);  if (($w != 0 && $new_w <= $w && $h == 0) ||      ($w == 0 && $h != 0 && $new_h <= $h) ||      ($w != 0 && $new_w <= $w && $h != 0 && $new_h <= $h))  {    // image is small enough    if ($dest != $src)      copy($src, $dest);    return;  }  // determine new size  if ($w != 0 && $new_w > $w)  {    $new_h = ($w / $new_w) * $new_h;    $new_w = $w;  }  if ($h != 0 && $new_h > $h)  {    $new_w = ($h / $new_h) * $new_w;    $new_h = $h;  }  // resize  $new = imagecreatetruecolor($new_w, $new_h);  if ($ext == 'png' || $ext == 'gif')  {    $trnprt_indx = imagecolortransparent($i);    // If we have a specific transparent color    if ($trnprt_indx >= 0)    {      // Get the original image's transparent color's RGB values      $trnprt_color = imagecolorsforindex($i, $trnprt_indx);      // Allocate the same color in the new image resource      $trnprt_indx = imagecolorallocate($new, $trnprt_color['red'], $trnprt_color['green'], $trnprt_color['blue']);      // Completely fill the background of the new image with allocated color.      imagefill($new, 0, 0, $trnprt_indx);      // Set the background color for new image to transparent      imagecolortransparent($new, $trnprt_indx);    }    // Always make a transparent background color for PNGs that don't have one allocated already    elseif ($ext == 'png')    {      // Turn off transparency blending (temporarily)      imagealphablending($new, false);      // Create a new transparent color for image      $color = imagecolorallocatealpha($new, 0, 0, 0, 127);      // Completely fill the background of the new image with allocated color.      imagefill($new, 0, 0, $color);      // Restore transparency blending      imagesavealpha($new, true);    }  }  imagecopyresampled($new, $i, 0, 0, 0, 0, $new_w, $new_h, imagesx($i), imagesy($i));  imagedestroy($i);  // save the image  switch ($ext)  {    case 'jpg':    case 'jpeg':      imagejpeg($new, $dest);    break;    case 'gif':      imagegif($new, $dest);    break;    case 'png':      imagepng($new, $dest);    break;  }  imagedestroy($new);}
You pass it an array of options, e.g.:
resize_image([  'source' => 'input.jpg',   'dest' => 'output.jpg',   'w' => 200,  'h' => 400]);
You can also leave out the destination filename if you want to overwrite the original.
