fopen, fread, fwrite question
I have 5 files in different directorys. I need to open each of these files and concantonate them into 1 file. the files are comma seperated line by line.

I have a grasp on how to open and read the files, but I am kinda lost on saving the group into 1 file.

TIA

Well, if you are reading the files correctly - you would have each file conetents bound to a scalar. With the scalars, you can write the file as so ->
PHP Code:
 $fp = @fopen( 'filename.txt', 'w' ) or exit( 'Need to check directory permissions' );
if ( $fp )
{
      @fwrite( $fp, $var_one . "\n" . $var_two . "\n" . $var_etc ); 
}
@flose( $fp );

Well, you can use just file and skip the other filesystem functions. Not nearly as fast as the other filesystem functions, but will do what you need ->
PHP Code:
 $data = file( 'the_text_file.txt' );
$data[0] = ( bool )false;
$data_scalar = implode( '', $data ); 

$data_scalar will hold your data with the first line being removed.

Where are the files stored? Are they on your site or another site?

they are on my site,.....they are exports from a shopping cart. I would assume since the files are owned by the same user, that I would be able to open them. I can open them and download them fine via FTP.

Are you using absolute paths? Example:
PHP Code:
/**************************
This
**************************/
$fp = fopen( 'site.com/files/file.txt', 'r' );
/**************************
Would Be
**************************/
$fp = fopen( $_SERVER['DOCUMENT_ROOT'] . '/files/file.txt', 'r' ); 


Are you getting any errors? Remove the error supression (@) from your functions so the errors will show...

won't work,...casue the export dir is not in the doc root,...

it would be more like,...

cwd = public_html

dir = ../secure_dir/exports

I think the reason I can't open the public_html dir is not the same owner as the export dir owner.

Permissions - is this your server or is it a shared host?
