utf8_encode和表情符号 [英] utf8_encode and Emoji

问题描述

我的utf8编码有问题。在wordpress数据库中，有很多表情符号，但是当我编码时，它们不再出现。有一个？

I have a problem utf8 encoding. In the wordpress database, there are many emojis but when I encode, they no longer appear. There is a "?" instead that appears.

你能帮我吗？我认为它来自utf8_encode

Can you help me ? I think it comes from utf8_encode

这是代码：

$results = $connection->query($req) or die(Array());

$results->setFetchMode(PDO::FETCH_OBJ); 

$i = 0;
$jsonArray = Array();
while($row = $results->fetch()) {   

    $jsonArray[$i][0] = utf8_encode($row->comment_author);
    $jsonArray[$i][1] = utf8_encode(nl2br($row->comment_content));
    $jsonArray[$i][2] = utf8_encode($row->comment_date);
    $jsonArray[$i][3] = utf8_encode($row->replyingToAuthor);
    $jsonArray[$i][4] = utf8_encode($row->comment_ID);

    ++$i;
}

$results->closeCursor();
$connection = NULL;
echo json_encode($jsonArray);

这是显示注释的行：

 $jsonArray[$i][1] = utf8_encode(nl2br($row->comment_content));

我对口音编码没有问题，只有表情符号

I have no problem with encoding accents, only with emoji

谢谢

推荐答案

我改进了它，因为它没有用。

I improve that, because it didnt't work.

函数：

function formatoAcentos($texto) {
$nvotexto = nl2br($texto);          // permite mantener el salto de línea
$nvotexto = utf8_encode($nvotexto); // permite caracteres especiales como los acentos
return $nvotexto;
}

函数调用。

echo formatoAcentos($row['descripcion_doc'])
