[SOLVED] Eliminating the new line

[ErcFrtz]

Hello, I have the following code:

if(file_exists($pigIDFile) && is_readable($pigIDFile))
{
    $readFile = file($pigIDFile);
    foreach($readFile as $line)
    {
      $pigIDarray[] = $line;
    }
  }

 

My question is with this code it puts the new line character at the end of each entry and I just want each line without that new line character. How do I eliminate it from $line so that my array is populated with each line without the new line character?

$string = str_replace('\n', '', $string);

This method is not working. I've tried exploding the string and eliminating it that way too but it's a single word on each line and it doesn't seem to eliminate the problem at all.

str_replace needs to have the \n wrapped in double quotes not single.  Alternatively, you can use trim

try printing your string with "echo htmlspecialchars($string);"

 

That should show you the raw string, maybe you can find some different line break thingy.

 

have you tried replacing "\r"? That is apparently another new line char

oh sorry, yeah

$string = str_replace("\n", '', $string);

 

forgot about that

Thank you. using trim() worked.
