How to skip images that http status 404 or 401? - php

Question

I am trying to save images from dropbox to my server. I have already done the code for that. I am also checking the HTTP status of the url before downloading the images with code. I am getting proper status but the issue is it always throws an error 401 even when i have put a condition to download images with status code 200 or 302. I am having the links of images in an excel file that i am reading with a laravel package. Please help me.

Image Status Check Function
public static function CheckLinkStatus($image)
{
$ch = curl_init($image);
curl_setopt($ch, CURLOPT_NOBODY, true);
curl_exec($ch);
$retcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
return $retcode;
}

Answer 1

Try this:
$ch = curl_init($image);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
if($httpCode != 404) //# if error code is not "404"
{
/* Your Function here. */
}
else
{
/* Handle 404 here. */
}

Answer 2

Try setting an array of http codes, like:
$httpCodes = [401,404];
And than just check:
if(!in_array(CheckLinkStatus($image),$httpCodes){
// YOur logic
} else {
// Handle 401 && 404
}
