Carriage Returns

[nejolley]

I've got an issue that I believe has something to do with the encoding of my text file. But I'm not sure how I go about changing that.  In short, what I'm really trying to accomplish is that when the file I've just created with PHP is opened in Notepad that it is formated exactly the way I intended it to. Particulary how the file handles carriage returns. So when I send a carriage return to the file I want to see a new line and not as a symbol "[]".

I'd need to see your input code to determine why you see a '[]' for line breaks.  Line breaks are specified by using \r\n.

It's not exactly a "[]" but just a small closed little box where I've inserted a \n.  But here is the code:

 

$stringData = "%BTW% /AF=c:\labels\lp_4x2_bin_id.btw /D=<Trigger File Name> /PRN=\"\\\dclaptop\Zebra S4M (203 dpi) - ZPL\" /R=3 /P /DD \n%END%\n";
fwrite($fh, $stringData);

Alright, I figured it out and found the solution.  Here's my updated code for those who are curious:

 

$fh = fopen($myFile, 'wb') or die("can't open file");
$stringData = "%BTW% /AF=c:\labels\lp_4x2_bin_id.btw /D=<Trigger File Name> /PRN=\"\\\dclaptop\Zebra S4M (203 dpi) - ZPL\" /R=3 /P /DD \r\n%END%\r\n";
fwrite($fh, $stringData);

 

According the the PHP.net "Windows based systems use \r\n as the line ending characters "

The other option is to open the file with wordpad, which knows that \n is a line terminator.

True. But in my case these files that are being created aren't being made for humans to open up and read.  Instead, another program which I use to create barode labels reads in the text file.  This other program didn't know how to handle the special character that was being created in my file and would error off.  Now with the file formatted correctly I'm now printing labels successfully.
