file_get_contents in wordpress function - file-get-contents

Question

This code works correctly and saves a remote image to localhost (this wordpress plugin save tmdb cast image to local address):
function dt_cast_2($id, $type, $limit = false)
{
$name = get_post_meta($id, "dt_cast", $single = true);
if ($type == "img") {
if ($limit) {
$val = explode("]", $name);
$passer = $newvalor = array();
foreach ($val as $valor) {
if (!empty($valor)) {
$passer[] = substr($valor, 1);
}
}
for ($h = 0; $h <= 500; $h++) {
$newval = explode(";", $passer[$h]);
$fotoor = $newval[0];
$actorpapel = explode(",", $newval[1]);
if (!empty($actorpapel[0])) {
if ($newval[0] == "null") {
$fotoor = DT_DIR_URI . '/assets/img/no_foto_cast.png';
} else {
$fotoor = 'https://image.tmdb.org/t/p/w90' . $newval[0];
$uploaddir = wp_upload_dir();
$uploadfile = $uploaddir['basedir'] . $newval[0];
if(!file_exists($uploadfile))
{
$contents= file_get_contents($fotoor);
$savefile = fopen($uploadfile, 'w');
fwrite($savefile, $contents);
fclose($savefile);
}
$fotoor = $uploaddir['baseurl'] . $newval[0];
}}}}}}
I have a problem in this function, the image is not saved to local.
Can someone give me the correct code?
function dt_image($name, $id, $size, $type = false, $return = false, $gtsml = false) {
$img = get_post_meta($id, $name, $single = true);
$val = explode("\n", $img);
$mgsl = array();
$count = 0;
foreach ($val as $valor) {
if (!empty($valor)) {
if (substr($valor, 0, 1) == "/") {
$mgsl[] = 'https://image.tmdb.org/t/p/' . $size . '' . $valor . '';
} else {
$mgsl[] = $valor;
}
$count++;
} else {
if ($name == "dt_poster" && $img == NULL) {
$mgsl[] = esc_url( DT_DIR_URI ) . '/assets/img/no_poster.png';
}
}
}

$fotoor = 'https://image.tmdb.org/t/p/w90' . $newval[0];
i replaced this code and work it.
$fotoor = 'https://image.tmdb.org/t/p/w90' . $newval[0];
$uploaddir = wp_upload_dir();
$uploadfile = $uploaddir['basedir'] . $newval[0];
if(!file_exists($uploadfile))
{
$contents= file_get_contents($fotoor);
$savefile = fopen($uploadfile, 'w');
fwrite($savefile, $contents);
fclose($savefile);
}
$fotoor = $uploaddir['baseurl'] . $newval[0];
