PHP method to remove BOM header

But PHP did not consider the BOM header problem at the beginning of the design, so it is easy to have problems during encoding and decoding

For example, the problem encountered today, json_decode , when the decoded string has a BOM header, json_decode fails to parse and returns NULL. (Why not automatically detect and remove the BOM header... small complaint)

I tried two ways to remove it:

$result = trim($result, "\xEF\xBB\xBF");
print_r(json_decode($result, true));
exit;

There is another kind that is more reserved:

$result = @iconv("UTF-8", "GBK//IGNORE", $result);
$result = @iconv("GBK", "UTF-8//IGNORE", $result);
 
print_r(json_decode($result, true));
exit;
