keys %online php translation help

[pcw]

Hi,

 

I am trying to convert an old perl script into php. And am stuck on the following code.

 

_{elseif (preg_match_all("m/^ONLINE:(.*)$/", $part))}

_{

_{if(!defined($online)){}

_{get_online();}

_}

_{$out .= implode($v1);}

_{map ("<a href=sb.php?action=display&login=$_&session=$input['session']>$_</a>") # This is line 426}

 

_{keys %online;  # This is line 428}

_}

 

When I do a syntax check, I get the following errors:

 

Parse error:  parse error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in sb.php on line 426

 

and

 

Parse error:  parse error, unexpected T_STRING in sb.php on line 428

 

I cant seem to work out a translation into PHP, any help is much appreciated

Place $input['session'] into {}

map ("<a href=sb.php?action=display&login=$_&session={$input['session']}>$_</a>");

 

as for the second one, I've no idea. What's this line supposed to do?

Thanks for your reply, that done the trick. As for keys %online, i think it translated to

 

_{array_keys($online);}

 

The syntax for that seems to be correct
