how to create a thumbnail while saving the image - image

Question

i have this code where the user uploaded image is saved.
is it possible in the meantime to create a thumbnail?
function saveImages($dataArray, $idArticles, $folderPath, $prefixFile){
$folderPathDefault = '../../media/articles/imm'.$idArticles.'/';
$prefixFileDefault = 'photo_';
if($folderPath == null){
$folderPath = $folderPathDefault;
array_map('unlink', array_filter((array) glob($folderPath."*")));
}
if($prefixFile == null){
$prefixFile = $prefixFileDefault;
}
if (!is_dir($folderPath)) {
// dir doesn't exist, make it
mkdir($folderPath);
}
$count = 1;
foreach ($dataArray as $data) {
$image_parts = explode(";base64,", $data);
$image_type_aux = explode("image/", $image_parts[0]);
$image_type = $image_type_aux[1];
$image_base64 = base64_decode($image_parts[1]);
$file = $folderPath . $prefixFile . $count . '.jpg';
file_put_contents($file, $image_base64);
$count ++;
}
}
Thank you

For those interested or solved with this function:
function resize_image($file, $w, $h, $crop=FALSE) {
list($width, $height) = getimagesize($file);
$r = $width / $height;
if ($crop) {
if ($width > $height) {
$width = ceil($width-($width*abs($r-$w/$h)));
} else {
$height = ceil($height-($height*abs($r-$w/$h)));
}
$newwidth = $w;
$newheight = $h;
} else {
if ($w/$h > $r) {
$newwidth = $h*$r;
$newheight = $h;
} else {
$newheight = $w/$r;
$newwidth = $w;
}
}
$src = imagecreatefromjpeg($file);
$dst = imagecreatetruecolor($newwidth, $newheight);
imagecopyresampled($dst, $src, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
return $dst;
}
function saveImages($dataArray, $idArticles, $folderPath, $prefixFile){
$folderPathDefault = '../../media/articles/imm'.$idArticles.'/';
$prefixFileDefault = 'photo_';
if($folderPath == null){
$folderPath = $folderPathDefault;
array_map('unlink', array_filter((array) glob($folderPath."*")));
}
if($prefixFile == null){
$prefixFile = $prefixFileDefault;
}
if (!is_dir($folderPath)) {
// dir doesn't exist, make it
mkdir($folderPath);
}
$count = 1;
foreach ($dataArray as $data) {
$image_parts = explode(";base64,", $data);
$image_type_aux = explode("image/", $image_parts[0]);
$image_type = $image_type_aux[1];
$image_base64 = base64_decode($image_parts[1]);
$file = $folderPath . $prefixFile . $count . '.jpg';
file_put_contents($file, $image_base64);
$count ++;
}
if (!file_exists('../../media/articles/imm'.$idArticles.'/thumbnail/')) {
mkdir('../../media/articles/imm'.$idArticles.'/thumbnail/', 0777, true);
}
$dir = "../../media/articles/imm".$idArticles."/thumbnail/";
array_map('unlink', glob("{$dir}*.jpg"));
$immagine= "../../media/articles/imm".$idArticles."/";
$files = glob("$immagine*.*");
$uno= 1;
for ($i=0; $i<count($files); $i++) {
$image = $files[$i];
$url = $image;
$imgResize = resize_image($url, 360, 270);
$path = '../../media/articles/imm'.$idArticles.'/thumbnail/thumbnail_photo_'.$uno++.'.jpg';
imagejpeg($imgResize, $path);
