fwrite - why is it skipping lines?

[roughie]

In my code below, I write the first line,

write intermediate lines, then write the

last line.

 

I want to skip a line after writing the first,

and only the first, line.

 

But - putting the "\n" after the first write

causes all subsequent writes to also skip

a line - something I do not want to happen,

even though those fwrites do not have the "\n"

in their syntax.

 

Why does the first write's skip action

carry into the rest of the fwrites, and how,

then, do I get that first skip executed without

influencing the rest?

 

<?php

$file      = fopen("./readArray.php","r");

$wfile  = fopen("./writeArray.txt", "w");

fwrite($wfile, "var jsArray = [\n");

while(! feof($file))

{       

  $phpLine = fgets($file);

  fwrite($wfile, $phpLine);

}

fclose($file);

fwrite($wfile, "]");

fclose($wfile);

?>

 

If I change the first fwrite statement to

fwrite($wfile, "var jsArray = [");

the writes get written each on their own line,

as I want it. But, then, how do I skip only

after the first fwrite? 

 

Thank you

use a simple counter

 

<?php

$count=0; 
while(! feof($file))
{         
   $phpLine = fgets($file);
   fwrite($wfile, $phpLine);
   if($count==0)
       fwrite($wfile, "\n");
    $count++;
}

The PHP manual for fgets() (http://us2.php.net/manual/en/function.fgets.php) says:

Reading ends when length  - 1 bytes have been read, on a newline (which is included in the return value), or on EOF (whichever comes first)

 

If your input file has newlines, then they are in the $phpLine after you read the file, and are being written to the new file.

 

You can get rid of them by using one of the trim() functions either on the read ...

$phpLine = trim(fgets($file));

or on the write ...

fwrite($wfile, trim($phpLine));
