[SOLVED] urlencode()

[orange08]

i came across urlencode() this function online...and know that it's used to encode URL...

 

can i know what's the purpose of doing so? for security purpose, so that people can't see what we actually pass through the URL?

It has nothing to do with security, as only (almost all) non-alphanumeric characters are encoded, such as spaces, brackets, etc.

 

This function is convenient when encoding a string to be used in a query part of a URL, as a convenient way to pass variables to the next page.

It simply encodes non-URL-safe characters into ones which are URL-safe using a widely accepted method (% followed by hexadecimal representation of the character).  It has nothing to do with security or obfuscation of data.

i did read about the link...but, i just can't understand then why to use it...and if i didn't use it to encode my link, then what is its shortcoming?
