php - 如何转义 PHP parse_ini_file 函数解析的文件中的特殊字符？

Question

我想在配置文件中保留某个字符串，以便由 PHPparse_ini_file()函数解析。但是，此字符串包含一些需要以某种方式编码的特殊字符（带有类似0x2Cor的代码）。0x3D有没有办法在这样的文件中用十六进制代码编写特殊字符？

The proper way to escape INI values is to enclose them in "double quotes". If your string doesn't contain double quotes, you can use it in as a value enclosed in double quotes.

Escaping single quotes with a backslash seems to work as long as there are not two consecutive double quotes in the value, as per http://php.net/manual/en/function.parse-ini-file.php#100046

If you want to do your own escaping, you certainly can:

htmlspecialchars / htmlspecialchars_decode escapes <,>,& and ".

htmlentities / html_entitity_decode will escape very aggresively (but also very safely) to HTML entities

urlencode / urldecode will escape all special characters except _-~..

base64_encode / base64_decode will ensure the encoded string contains only alphanumeric characters and +=/. This might be optimal for encoding binary data but doesn't preserve readability.
