ignore an empty line in txt file?

Anon

Hi,

I'm wondering if it's possible for php to know if a line in a txt file is empty and if so to not attempt to output information from it?

I have some code which I've been working on for a couple of days, which sets the amount of records per page you view, and explodes each line from a txt file into an array, however if I have it set to 5 records per page and there is only 2 records to view I get 3 empty records 🙁

Here is my code:

$file=file("data.txt");
$rows=5;
if ((!$offset) || ($offset < 0)){
$offset=0;
}
$count = count($file);
$a = "there are no more entries, thank you ";
echo "There are $count entries";
for ($i=$offset;$i<($offset+$rows);$i++) {
$continue = "<a href=\"?rows=$rows&offset=$nextoffset\">Next</a>";
if ($count < ($offset+1) ){
$output = "$a";
$continue = "No More Entries";
$i = $offset+$rows;
}
$array=explode("|",$file[$i]);
for($y=0;$y<count($array);$y++){

}
$nextoffset=$offset+$rows;
$prevoffset=$offset-$rows;
$output = "NAME$array[0]
From:$array[1] 
Comment:$array[2] 
Mail $array[3] 
website $array[4] 
$array[5] ";
echo "$output";
}
}

$output2 = "<div align=center><a href=\"?rows=$rows&offset=$prevoffset\">Previous</a>  |  $continue</div>";

I'd be grateful for any help, thanks!

have you thought of removing the line from the txt file with PHP rather than ignoring it?

If you want to keep the empty line send a copy of the txt file to me and i will create the code for you.

what it is, is not a empty line in the middle of the file, its the empty lines, or rather the end of the file.

if there are 13 lines with data, and the script is displayings 5 lines per page then the script displays the 3rd page as containing 3 lines with data and displays a further 2 lines with no data in them 🙁.

the file contents look like this:

using my code in the first post you should be able to see what I mean if you add extra lines and save it as data.txt

I've got a work around for just now, but I'd like to store my data seperated by | instead of having the way I'm doing it now which is taking up a lot of file space.

Any help would be great, thanks

Ok My Next Post Will Contain The Code Needed

Ok, i struggled through...
The following code is working and tested!
You should be paying for this!!!
This is COMPLETE CODE.
change the $fileName to the name and path of your file. Then save this script as ignorelines.php or it wont work!

<?
if ($page==""){
$page=1;
}
//enter your filename (+ path if necessary) below
$fileName = "users.txt";

$file_pointer = fopen($fileName, "r");
$data = fread($file_pointer, filesize($fileName));
fclose($file_pointer);
$data = ereg_replace("\n", "#", $data);
$disp = ereg_replace("#", " ", $data);

$count=0;
$len=strlen($data);//get the length of the file in characters

for($i=0;$i<$len;$i++) {
$chrcheck=$data[$i];
if($chrcheck=="#") {
$count=($count+1);// $count is the number of LINES in the document
}
}
$count=$count+1;

$line=explode("#", $data);
$no = 0;
for($i=0;$i<$count;$i++) {
$echo = $line[$i];
$lenLine=strlen($line[$i]);
if($lenLine < 2) {
$lines=$i;
break;
}
else{
$detail[$no]=explode("|",$line[$i]);
$no = $no + 1;

}
}

$entriesPerPage = 5;
$to = ($page*$entriesPerPage);
$from = ($to - $entriesPerPage);
$from = $from + 1;
if($lines < $from){
echo"No More";
}
if($lines >= $from){
if($lines < $to) {
$to=($to-($to-$lines));
$to=$to+1;
for($i=$from;$i<$to;$i++) {
$j = $i - 1;
$name = $detail[$j][0];
$location = $detail[$j][1];
$comment = $detail[$j][2];
$mail = $detail[$j][3];
$site = $detail[$j][4];
$date = $detail[$j][5];
// THIS ECHO IS YOUR DISPLAY! MUST BE SAME AS BELOW
echo"Entry No. - ${i} Name - ${name} Location - ${location} 
Comment - ${comment} E-Mail - ${mail} Website - ${site} 
Date - ${date} ";
}
$prev = $page - 1;
if($prev > 0) {
echo"<a href='ignorelines.php?page=${prev}'>Previous</a> | Next";
}
else {
echo"Previous | Next";
}

}

if($lines >= $to){
$to=$from+5;
for($i=$from;$i<$to;$i++) {
$j = $i - 1;
$name = $detail[$j][0];
$location = $detail[$j][1];
$comment = $detail[$j][2];
$mail = $detail[$j][3];
$site = $detail[$j][4];
$date = $detail[$j][5];
// THIS ECHO IS YOUR DISPLAY! MUST BE SAME AS ABOVE
echo"Entry No. - ${i} Name - ${name} Location - ${location} 
Comment - ${comment} E-Mail - ${mail} Website - ${site} 
Date - ${date} ";
}
$prev = $page - 1;
$next = $page +1;
if($prev > 0) {
if($next <= $lines){
echo"<a href='ignorelines.php?page=${prev}'>Previous</a> | <a href='ignorelines.php?page=${next}'>Next</a>";
}
}
if($prev > 0){
$n = ($next*$entriesPerPage)-$entriesPerPage;
if($lines < $n) {
echo"<a href='ignorelines.php?page=${prev}'>Previous</a> | Next";
}
}

if($prev < 1){
$n = ($next*$entriesPerPage)-$entriesPerPage;
if($n < $lines) {
echo"Previous | <a href='ignorelines.php?page=${next}'>Next</a>";
}
}

 if($prev < 1){
     $n = ($next*$entriesPerPage)-$entriesPerPage;
     if($n > $lines){
         echo"Previous | Next";
     }
 }


}

You have to give me a good Vote Now!
