Arrays and Files

[anm]

OK, so I'm trying to get some info into an array, and then print it to the screen. I have a file named dlist.php, which is what I'm reading into an array using file(). So I have the following code:

$d = file("dlist.php");

 foreach($d as $key=>$val) {
  $data[$key] = explode("||", $val);
 }

 print "$data[5][0]";
 print "$data[5][1]";

The file is the following:

<?php if ($_SERVER['PHP_SELF'] == "dlist.php") {
header("Location: index.php");
}
?>
english||kurash

The output is the following:

[0][1]

Why won't it appear as the text in the file? Is it a problem because of the first 4 lines, if so, how do I make the foreach skip those?

Sorry, it appears I posted this in the wrong forum. Not very used to this forum yet -- obviously, I just signed up! Sorry!

Hi,

try

print $data[5][0];
print $data[5][1];

or

print "{$data[5][0]}";
print "{$data[5][1]}";

EDIT: You might need to use $data[4][0] and $data[4][1]

Thanks so much! It works! I never really did arrays formally, and what I've acquired in knowledge of them has been sorta patchy. I mean I completely forgot that arrays started indexing at 0!! Pathetic. . .

Thanks again

EDIT

Another question. Since I have the protective PHP at the top to stop people from just viewing the code inside, is it possible to start the array on the 4th index? (i.e. the fifth line). Or how would I make it so the array would only include the lines of words? Because I need to sort it (using asort()) and I don't want those lines to get included.

Try something like this

$d = file("dlist.php");

foreach($d as $key=>$val) {
  $data[$key] = explode("||", $val);
}
$data = array_slice ($data, 4);
print $data[0][0];
print $data[0][1];

Thanks, it works.

Just one other question and then I'm off to code some more.

I've got now an associative array where the english word is the key -- so I've got

house||kurash
to be||waalak

Is there a way to sort it by the kurash and waalak entries as opposed to the house and to be ones??

Now I'm having another problem with these stupid arrays. . . 🙁

My code is:

function english() {
  index();
 $d = file("dlist.php");

 foreach($d as $key=>$val) {
  $data[$key] = explode("||", $val);
 }
  $data = array_slice ($data, 4);
  asort($data);
  $end = count($data) - 1;
  for($num=0;$num<=$end;$num++) {
 print "<p><span style=\"font-size:16pt\">".$data[$num][0]."</span>&nbsp;&nbsp;--&nbsp;&nbsp;<span style=\"font-size:12pt\"><i>". $data[$num][1] ."</i></span>";
 }
}

For some reason, it's not getting sorted alphabetically! I'm ending up with just the line-by-line output. . .starting with the first and ending with the last. Why is this?

[tsinka]

Ok,

in that case try something like this instead of using asort:

function sortit($arr1, $arr2)
{
   if ($arr1[0] == $arr2[0]) {
       return 0;
   }
   return ($arr1[0] < $arr2[0]) ? -1 : 1;
}

function english() {
  .....
  usort($data,"sortit");
  ......
}

You might need to use strtolower inside sortit if you want to sort the array values in a case insensitive way.
