New lines added everytime CSV file is saved

[bsewell]

Hi everyone,
basicly I have a CSV file which uses ^ as a delimiter. I have a textarea which is populated by the contents of the CSV file, and after editing it the user is redirected to the edit page.

For some reason, everytime I save the file there is a line which is added between each line of text. I want to get rid of the empty lines.

Edit.php

<form action="save.php" method="post">
<textarea name="events" cols="100" rows="10" style="text-align:left">
<?php 
	if (($handle=fopen("events.csv","r"))!==FALSE)
	{
		$rowNo=1;
				
		while (($data = fgetcsv($handle, 1000, "^")) !== FALSE) 
		{
			$num=count($data);
			$data=str_replace("&rsquo;","'",$data);?>
			
			<?php		
			if ($rowNo==1)
			{
				for ($c=0; $c < $num; $c++)
				{
					echo $data[$c];
				}
			}
			
			else
			{
				for ($c=0; $c < $num; $c++)
				{
					echo $data[$c];
					
					if ($c==($num-1))
					{
					
					}
					
					else
					{
						echo "^";	
					}
				}
			}
			?>
			
			<?php
						
			$rowNo++;
		}
	}	
?>
</textarea><br />
<input type="submit" name="Edit" value="Save" />
</form>

Save.php

<?php
$events=$_POST['events'];

$myFile = "events.csv";
$fh = fopen($myFile, 'w') or die("can't open file");
$events=str_replace("&rsquo;","'",$events);
$events = stripcslashes($events);
fwrite($fh,$events);
fclose($fh);
header('Location:edit.php');
?>

Example of events.csv

Events / Summer 2010
Milkshake Disco^A disco for 6 to 10 year olds^Friday 28th May^Friday 25th June
Summer Project^A project running from Mon - Thurs for 6 to 10 year olds^August 2nd to 26th

What do I do to get rid of the lines that are added?

Cheers,
Ben

When you are opening whole file in textarea then why you are treating it as csv, simply load text area with content, modify and save. I hope following code will help you

<form action="save.php" method="post">
<textarea name="events" cols="100" rows="10" style="text-align:left">
<?php 
	$handle=fopen("events.csv","r");
	echo fread($handle,filesize("events.csv"));
	fclose($handle);

?>
</textarea><br />
<input type="submit" name="Edit" value="Save" />
</form>

That code worked straight away. I don't understand why the lines were appearing but it doesn't happen with you code :)
