Re: problems creating a png image from an array{HELP} including the source code

I'm probably just a Luddite, but I don't trust ++ and assignment operations *that* far. > $id++; > } > } > } > > $nodes=array_values(array_unique($pipes)); > for ($i=0;$i<sizeof($nodes);$i++) > { > $k=$i+1; > echo "$k,"; > echo $nodes[$i][0]; > echo ","; > echo $nodes[$i][1]; > echo "/<br>"; > } > echo "-1//<br>"; > $temp_pipes=$pipes; > > $i=sizeof($temp_pipes); > $size=$i; > $pipe_id=1; > while(!empty($temp_pipes)) > { > $current_node=array_shift($temp_pipes); > reset($nodes); > while((current($nodes))!=$current_node) > {next($nodes);} This looks suspicous... I'm not quite sure what's going on here, but I'm expecting you'd want to walk from node to node, or maybe skip any duplicates, but why are you zipping through the entire array looking for the node that you are on?... There's got to be a better way to track this -- maybe just using an indexed array for your nodes, and knowing that you are currently on $node_index or something... Is a "node" an array? I wouldn't be using == on two arrays... Maybe it's fine, but again that Luddite factor works in, and I'd be testing the elements individually... > $pipes_nodes[$size-$i+1][0]=key($nodes)+1; > echo ($pipe_id++).",$ECODE,".$pipes_nodes[$size-$i+1][0]; > > $current_node=array_shift($temp_pipes); > reset($nodes); > while((current($nodes))!=$current_node) > {next($nodes);} Same here... > $pipes_nodes[$size-$i+1][1]=key($nodes)+1; > > echo ",".$pipes_nodes[$size-$i+1][1]."/<br>"; > } > echo "-1//<br>"; > if (!isset($pressure_drop_nodes)) > > echo "<form action='convert.php' method='post' > name='form_convert' id='1'>"; > echo "<TABLE border=0 width='80%'>"; > echo > " > <TR>"; > echo " <TD width='30%'>??????
