Author: User
PHP rawurlencode and urlencode functions: both functions are for string escaping to make them suitable for file names. Which one should I use? Which is more standard? Conclusion: rawurlencode complies with RFC1738, a 94-year international standard memorandum. urlencode implements the rawurlencode and urlencode functions of traditional PHP.

Problem: both functions are for string escaping so that they can be used as file names. Which one should I use? Which is more standard?

Conclusion:
Rawurlencode complies with RFC 1738,
Urlencode implements the traditional method. The main difference between urlencode and the above method is that the escape of spaces is '+' rather than '% 20'
The encodeURI of javascript is also a 94-year standard,

Javascript escape is another way to mark unicode encoding with "% xxx.

Rawurlencode is recommended in PHP. Discard urlencode

Note: php rawurlencode! = JS encodeURI
