i'm currently writing a script and pass the information to other site through fopen.

the info contains space and line break

i can insert %20 for space , then how's the line break, thanks

    What do you mean line break the only others are line feed and carriage return %20 is the HEX for a space   is the HTML for a space, %D would be HEX for a carriage return, and line feed is HEX %A but you normally would not use such stuff

    I do not see where using fopen you would have a need for any of all that. Here the

    fopen ( string filename, string mode [, bool use_include_path [, resource zcontext]] )

    only requires a filename and the mode r, r+,w,w+,a,a+,x, and x+
    discussed fopen() how could you possibly have a filename that has a 'line break' carriage return or line feed?
