I am inserting into a mysql database. I get the following error when trying to do the insert
Incorrect string value: '\xF0\x9F\x87\xB7\xF0\x9F...' for column 'field_4' at row 1
I thought I had figured out this error by simply changing the column encoding the to utf8mb4 and had tested but recently this error appeared again. I am using php to parse the string and run the following function before inserting...
function strip_emoji($subject) {
if (is_array($subject)) {
// Recursive strip for multidimensional array
foreach ($subject as &$value) $value = $this->strip_emoji($value);
return $subject;
} else {
// Match Emoticons
$regexEmoticons = '/[\x{1F600}-\x{1F64F}]/u';
$clean_text = preg_replace($regexEmoticons, '', $subject);
// Match Miscellaneous Symbols and Pictographs
$regexSymbols = '/[\x{1F300}-\x{1F5FF}]/u';
$clean_text = preg_replace($regexSymbols, '', $clean_text);
// Match Transport And Map Symbols
$regexTransport = '/[\x{1F680}-\x{1F6FF}]/u';
$clean_text = preg_replace($regexTransport, '', $clean_text);
return
}
There are several similar questions to this but I still have these errors. Any further advice on how to prevent this error? I realize that it is an emoji unicode character / sprite but not sure how to deal with it.
