htmlentities無法使用°（°）

Question

遇到了一些麻煩但又無法解決問題，我想將°char保存為° 在數據庫中

//$_POST['group'] = "1° BF"

$group = htmlentities($_POST['group'], ENT_QUOTES, "UTF-8");

//$group should be "1° BF" but still shows as "1° BF"

文檔字符集也定義為UTF-8

Answer 1

好吧，我想我終於明白了。 如上所述，我實際上以°存儲在DB中，因此我需要使所有字符都相同，因為我混合使用了°，º，ª（所有這些字符都是從某個古老的DBF導入的）。 你怎么看待這件事？

//$group = 1° BF, or 1º BF, or 1ª BF

//check var length here
$group = htmlentities($_POST['group'], ENT_QUOTES, "UTF-8");
$group = str_replace("°", "°", $group);
$group = str_replace("º", "°", $group);
$group = str_replace("ª", "°", $group);
$group = str_replace("|", "°", $group);

//$group = "1° BF", ready to go to DB.
