Array Output from CLI

[varadorn]

Please help.

I have the following data file (Let's call it data.txt):

201200|0.00470|0.01480|0.00720|0.00400
201202|0.03490|0.01960|0.01190|0.00861
201203|0.01429|0.03370|0.01245|9.99999
201204|0.00490|0.01560|0.01590|0.00861
201205|0.01490|0.02370|0.03999|0.04234

Here is my php script (Let's call it script.php):

<?php
$filename = $argv[1];
$array = file($filename);
foreach ($array as $line) {
list($x,$a,$b,$c,$d) = explode('|',$line);
$array2 = array("A"=>$a,"B"=>$b,"C"=>$c,"D"=>$d);
asort($array2);
reset($array2);
while (list($key,$val) = each($array2)) {
echo "|$key|$val";
}
echo "\n";
}
?>

When I ran: #php script.php data.txt
I got the following result:

|D|0.00400
|A|0.00470|C|0.00720|B|0.01480
|D|0.00861
|C|0.01190|B|0.01960|A|0.03490
|C|0.01245|A|0.01429|B|0.03370|D|9.99999

|A|0.00490|D|0.00861
|B|0.01560|C|0.01590
|A|0.01490|B|0.02370|C|0.03999|D|0.04234

I wonder whether anyone know why my result did not print line by line. I was expecting the result as follows:

|D|0.00400|A|0.00470|C|0.00720|B|0.01480
|D|0.00861|C|0.01190|B|0.01960|A|0.03490
|C|0.01245|A|0.01429|B|0.03370|D|9.99999
|A|0.00490|D|0.00861|B|0.01560|C|0.01590
|A|0.01490|B|0.02370|C|0.03999|D|0.04234

It seems to me that when php create an array; it also creates some extra new line.

Please advise.

Thank you,
Dorn.

Try this:

<?php
$filename = $argv[1];
$array = file($filename);
foreach ($array as $line) {
  list($x,$a,$b,$c,$d) = explode('|', trim($line));
  $array2 = array("A"=>$a,"B"=>$b,"C"=>$c,"D"=>$d);
  asort($array2);
  reset($array2);

  while (list($key,$val) = each($array2)) {
    echo "|$key|$val";
  }

  echo "<br/>\n";
}
?>

The "extra new lines" are the newline characters that were in the original text file (you'll notice that all of the extra newlines appear immediately after array entries that were at the ends of their lines in the original file); you didn't trim them off when you read the file in.

I see. Thank you very much for both of you.
