Php json _decode function returns null on long data

Burak.H :

I pull data from a json file on the remote server. This json file has 97000 Lines of json code. It returns null when I decode the Json file. When I debug the Json errors, I see that there is no error.

Json file : https://opendata.ecdc.europa.eu/covid19/casedistribution/json/

$json = file_get_contents("https://opendata.ecdc.europa.eu/covid19/casedistribution/json/");
$json =  json_decode($json, true);
var_dump($json); // Return Null

But when I decode another json file there is no error

$json = file_get_contents("https://randomuser.me/api/");
$json =  json_decode($json, true);
var_dump($json); // Return Array

Could this be due to the size of the data?

Thanks for advance

deceze :

The file starts with a BOM, which is a syntax error for json_decode.

Ultimately this should be fixed by the host, as a workaround you can strip the first three bytes:

if (substr($json, 0, 3) == "\xEF\xBB\xBF") {
    $json = substr($json, 3);
}
