removing ^M characters?

[Admin]

anyone know how to remove those annoying '^M' characters that microsoft adds at the end of a line? str_replace isn't working because i can't get the character to reproduct properly.

any ideas?!?

[sde]

i hate that crap and i don't know.

[Admin]

the only idea i have right now is to split my string into an array and just chop off the last character from each line. nasty.

you about ready for a snow trip?

[Admin]

this seems to be working...

PHP Code:

    $OutPut = explode("\n",$_POST[info]);

    for($i=0; $i < count($OutPut); $i++)
    {
      $RealOutPut .= substr($OutPut[$i], 0, -1) . "\n";
    }

yeah, i'm ready for a trip. i have the AWD, but i just put performance street tires on lol .. it will be interesting.

PHP Code:

$str = "nice line with crap on the end\r\n";
$str = preg_replace("/[\r\n]/", "", $str); 


Or just "/[\r]/" to remove the CR and no the unix LF.

-r

Not php, but useful:

perl command line one-liner:

perl -pi.orig -e 's/\r//g;' file

(removes all CR's from the file and saves the original file as "file.orig")

perl:

while (<>) {
  chomp;
  s/\r//g;
  # do stuff
}

..or remove the chomp and just use s/[\r\n]//g;

-r

[idx]

PHP Code:

$str = "ms cruft\r\n";
$str = str_replace ("\r\n", "", $str); 


This might work too..

idx, you think that will match the ^M character? I didn't even bother trying that because VIM was displaying ^M at the end of every line..

What is this ^M character all about? What do you mean 'Microsoft adds to the end of every line' ?

I'm confused now but if this happens to me in the future then I got some clue of why.

Yeah, \n is the unix line feed and \r is the carriage return. Although in editors you see ^M. You can remove the ^M's in VIM too.

Press : to get in command mode. then type:

g/\r//s//g

(I think that's right. it's close)

Check out table 11-1.

What do you mean 'Microsoft adds to the end of every line' ?

Yes, by default MS ends every line in a plain text file with a carriage return then a line feed. (\r\n) But unix/linux/etc only use the line feed so we end up seeing the CR as if it was actually part of the file.

Ever try to open a unix file in notepad? It gets all squished together with little blocks (the LF's) in between since it can't find the CR to separate lines.

I believe MAC's did something weird like end lines with only a CR.. Although maybe that was before the OSX days.
