PHP's Rawurlencode and UrlEncode functions

PHP's Rawurlencode and UrlEncode functions

Problem: 2 functions are for string escaping so that they are suitable for file names. Which one should I use? Which is more standard?

Conclusion:
Rawurlencode Compliance is the 94 international standard memo RFC 1738,
UrlEncode is the traditional approach, and the main difference is that the escape from the space is ' + ' instead of '%20 '
JavaScript's encodeURI is also the 94 standard,

The escape of JavaScript is another way to mark Unicode encoding with "%xxx".

Recommended for use with Rawurlencode in PHP. Discard UrlEncode

Note: PHP rawurlencode! = JS encodeURI
