Loop an fgets()
i.e.
$fp = fopen($file)
while ($filerow = fgets($fp,1024)) /* Read 1024 bytes or to EOL, whichever
is first) */
{
$filerow = str_replace("; ","", $filerow);
$filerow = str_replace("# ","", $filerow);
$filerow = str_replace("\r","", $filerow);
$size = strlen($filerow);
$row_split = preg_split("/\s+/", $filerow);
$value1 = $row_split[0];
$value2 = $row_split[1];
$value3 = $row_split[2];
}

Subject: [PHP] Upload problem - PC, *nix, and Max EOL characters

> This works perfectly well when the data is uploaded from a PC, but it

> $filearray[0] (uploaded via a PC) I get one line, but when I ouput
> $filearray[0] from a file uploaded via a Mac I get the entire file.
> Therefore the problem occurs with:

> $filearray = file($file);
> while (list(,$oneline) = each($filearray))

> I thought I had found a solution to the problem on the web* where I

>
> --------------------------
> ; If your scripts have to deal with files from Macintosh systems,
> ; or you are running on a Mac and need to deal with files from
> ; unix or win32 systems, setting this flag will cause PHP to
> ; automatically detect the EOL character in those files so that
> ; fgets() and file() will work regardless of the source of the file.
> ; auto_detect_line_endings = Off
> --------------------------
>
> However, this never solved the problem.
>
> The file itself is stored in a database, so how can I get rid of the EOL
> characters before it is being inserted? Is there a function to change
> the Unix EOL chars to PC EOL chars?
>
> Thanks in advance.
