[RESOLVED] Writing a new line using fwrite...

mberman

Is it possible to make a new line in a text file, while writing using fwrite()? I'm planning to write values to a file, and then retrieve them using file() to store them in an array, but I can't figure out how to get a new line. I've tried concatonating a "\n" onto the backend of the string to be written, but, that just adds a \n to the end of the line. Is there a way to use an ASCII value or something?

bump..... any suggestions?

"\n" should work, you might want to try "\r\n" too, it's different between Windows and *NIX.

Post the code if you still can't figure it out...

i think he's looking for append.... put "a" in the mode of fopen() then write out \nline\n

There's a comment on this page (about the 2nd or third comment down) that discusses this issue.

Here is the quote, may help.

The way I understand fputs (which is purported as an alias to fwrite which can be "Binary Safe")...
<pre>$fp = fopen("something.txt","w");
$string = "Hello World\n"; // escape the slash from being magically
// being transformed into a newline
fwrite($fp, $string); // will proccess /n as newline ...
fwrite($fp, $string, strlen($string)); // will write the entire string to file without changing the '/n'
// into a single byte for newline on Unix-like machines or CR/LF on Win32 machines

</pre>

Hope this helps explain the definition of "could be Binary Safe". This is the reason why you must specify the length!

Allrighty. I'll try out those solutions and post again if I can't get one to work. BTW, I'm on a *NIX (Linux) system - if that makes significant difference.
