What on earth does this do?

Hi everyone,

Ok, so I just finished a script, and was just optimizing it, when I came across this line of code in one of the replacement passes:

$str2 = preg_replace("/(\s){2,}/",'$1',$newcontent);

PHP:

I forgot to comment the code and now I don't know what this line replaces. If anyone can help me, it would be great! Thanks!

 

I think it strips extra whitespaces, but I have not seen it done that way before.

 

i think it strips first 2 spaces.

 

It removes 2+ spaces , I don't think it's complete though

 

Thanks for your help! +1 rep to all who helped!

 

$str2 = str_replace("  ","",$from_content);

PHP:

$str2 will replace 2 empty spaces, with nothing $from_content
