如何在PHP字符串中删除％EF％BB％BF [英] How to remove %EF%BB%BF in a PHP string

问题描述

我正在尝试使用Microsoft Bing API.

I am trying to use the Microsoft Bing API.

$data = file_get_contents("http://api.microsofttranslator.com/V2/Ajax.svc/Speak?appId=APPID&text={$text}&language=ja&format=audio/wav");
$data = stripslashes(trim($data));

返回的数据在返回的字符串的第一个字符中带有一个''字符.它不是空格，因为我在返回数据之前对其进行了修剪.

The data returned has a ' ' character in the first character of the returned string. It is not a space, because I trimed it before returning the data.

"字符原来是％EF％BB％BF.

The ' ' character turned out to be %EF%BB%BF.

我想知道为什么会发生这种情况，也许是Microsoft的错误?

I wonder why this happened, maybe a bug from Microsoft?

如何在PHP中删除此％EF％BB％BF?

How can I remove this %EF%BB%BF in PHP?

您可以仅将 substr 剩下的不用 UTF-8 BOM :

// if it’s binary UTF-8
$data = substr($data, 3);
// if it’s percent-encoded UTF-8
$data = substr($data, 9);
