<h2>函数说明</h2>
<p>此函数用于将给定的字符串转换为Quoted-Printable编码格式，通常用于电子邮件的正文或邮件头中。Quoted-Printable编码可以帮助在传输过程中保持字符的可读性，同时避免二进制字符被错误处理。</p>

<h2>函数语法</h2>
<pre>string quoted_printable_encode ( string $str )

</div></div>

$str = "Hello, this is a test!";
$encodedStr = quoted_printable_encode($str);
echo $encodedStr;

示例代码的说明:

在这个例子中，首先定义了一个字符串变量 $str，它包含了一个常规的文本。然后通过调用 quoted_printable_encode 函数对该字符串进行Quoted-Printable编码，最后输出编码后的字符串。编码后的字符串将符合Quoted-Printable标准，可以用于电子邮件内容的安全传输。
