Re: file/array manipulation[RESOLVED]

["Mignon Hunter" <mignon.hunter@xxxxxxxxxxxxxxx>]

Got it - never mind

instead of 
$new_array = array($line_split[0] => $line_split[1] );

  it's

$new_array = array($line_split[0] , $line_split[1] );

But I'm still not sure how it works so well...


************************
Ok I got this to work but I'm not sure how -- and am having trouble re-producing the data:

My script I have so far is:

$lines = file('test2.csv');
foreach ($lines as $line) {
	$line_split = explode(",", $line);
	if(!(empty($line_split[0]) ) ){
		//echo "I'm not empty";
		$new_array = array(
			$line_split[0] => $line_split[1]
			);	   
		}		
		print("<pre>");
		print_r($new_array);
		print("</pre>");		
		//echo "<tr><td>" . $new_array[0] . "</td><td>" . $new_array[1] . "</td></tr>";// this doesnt work			
}

Here's what the printed format spits out (abbreviated):

Array
(
    [R] => "ABC company
)
Array
(
    [R] => "ABC company
)
Array
(
    [R] => "ABC company
)
Array
(
    [R] => "ABC company
)
Array
(
    [O] => XYZ company
)
Array
(
    [O] => XYZ company
)
Array
(
    [O] => XYZ company
)
Array
(
    [O] => XYZ company
)

So - I'm getting the write letters assigned to write companys which is great. But my echo line:

echo "<tr><td>" . $new_array[0] . "</td><td>" . $new_array[1] . "</td></tr>";// this doesnt work	

Do I have several arrays or a multidim array?

Thanks for any guidance

//Assuming it's the FIRST character of each line that has space or category:
//Check first character:
if ($line[0] != ' ' && $line[0] != "\t"){
  $category = $line[0];
}

echo "$category\t", trim(substr($line, 1)), "<br />\n";
