CRLF to LF PHP
So I have this PHP script that takes info from HTML form and saves the info to a txt file.

Here is the code

Code:
<?php
$input = $_POST['msg'];
$dateposted = date("m-d-Y-His");
$fp = fopen("/some/location/public_html/sh/$dateposted.txt", "w"); 
fwrite($fp, $input.).'&nbsp;';
fclose($fp);
header("Location: http://SomeWebSite.com");
?>

This seems to work fine as it spits out a text file. BUT what I need to make sure happens is that any windows returns (CRLF) are changed to unix returns (LF).

I am sure this is easy to do but have not been able to figure it out.

Thanks in advance for your help!

I don't have any experience with PHP, but after about 5 minutes of searching I believe I've found something that will help.

Yeah I seen that but can't figure out how to incorporate that into what I have. I will keep on trying.

I think I figured it out. I used str_replace instead of preg_replace.

Code:
<?php
$input = $_POST['msg'];
$out = str_replace(array("\r\n"), "\n", $input);
$dateposted = date("m-d-Y-His");
$fp = fopen("/some/location/public_html/sh/$dateposted.txt", "w");
fwrite($fp, $out).'&nbsp;';
fclose($fp);
header("Location: http://somewebsite.com/sh/sh.html");
?>

If there is a better way of doing this let me know.

Thanks again!

Some systems translate \n into \r\n for you when you write to text files, so I wasn't sure your string even contained \r\n in the first place.

Knowing for sure that string replacement will actually work here, I'd do this to delete all carriage returns:

Code:
$input=strtr($input, array("\r" => ""));

Nothing wrong with the way you're doing it, though. This may be slightly more efficient but I don't think it's a big deal.

Now I would like to ftp this file created to another server.

I have tried the following:

Code:
<?php
$input = $_POST['msg'];
$out = str_replace(array("\r\n"), "\n", $input);
$dateposted = date("m-d-Y-His");
$fp = fopen("/home/somefolder/public_html/sh/$dateposted.txt", "w");
fwrite($fp, $out).'&nbsp;';
fclose($fp);

// FTP access parameters
$host = 'somesite.com';
$usr = 'usesrname';
$pwd = 'password';
 
// file to move:
$local_file = $fp;
$ftp_path = '/home/somefolder/public_html/';
 
// connect to FTP server (port 21)
$conn_id = ftp_connect($host, 21) or die ("Cannot connect to host");
 
// send access parameters
ftp_login($conn_id, $usr, $pwd) or die("Cannot login");
 
// turn on passive mode transfers (some servers need this)
// ftp_pasv ($conn_id, true);
 
// perform file upload
$upload = ftp_put($conn_id, $ftp_path, $local_file, FTP_ASCII);
//ftp_put($conn_id, $ftp_path, $local_file, FTP_ASCII); 
// check upload status:
print (!$upload) ? 'Cannot upload' : 'Upload complete';
print "\n";
header("Location: http://somesite.com/sh/sh.php");
?>

When I use that I get an error.


Warning: ftp_put() expects parameter 3 to be string, resource given in /home/somesite/public_html/sh/data.php on line 28

This is the code on that line:

Code:
$upload = ftp_put($conn_id, $ftp_path, $local_file, FTP_ASCII);

I am no expert at ay of this so I am sure there is a better way to ftp via PHP.

I will keep looking around for an answer in the meantime.

Thanks in advance!

It's telling you what the problem is -- something wrong with $local_file.

What is $local_file, exactly?

You define it with $local_file=$fp, and what is $fp, exactly?

Well, it was a file pointer, which is not and never was a string, and it complains that it wants a string. (You kind of called fclose($fp) a few lines above, so now it's not really anything at all.) If it expects a string, what does it want? The file name, not a file pointer. Give it "/home/somefolder/public_html/sh/$dateposted.txt"

I thought $fp was going to be a txt file with todays date. I tried

Code:
/home/somefolder/public_html/sh/$dateposted.txt

It complained about unexpected "/"

I also tried
Code:
$local_file = $dateposted.txt;

and it seemed to try and find a file but missing the .

Code:
Warning: ftp_put(01-12-2012-110821txt) [function.ftp-put]: failed to open stream

Thanks for your help Corona688!
