[RESOLVED] converting text from Unix to MS

jkurrle

When converting text from a unix environment, one needs to add a linefeed to each line. Which line of code is correct?

($str is the data of the file loaded as a variable)

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

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

Thanks for assistance.

If you want to go from UNIX to MS:

str_replace("\n", "\r\n", $text);

If you aren't sure if it' has UNIX or MS style line breaks, you could use:

preg_replace('/(?<!\r)\n/', "\r\n", $text);

Ok, I wrote this little code snippet, which seems to work for me.

    //Get the contents of the old file
    $str=file_get_contents($filename);
    //Replace CR with CR/LF
    $str=str_replace("\r","\r\n",$str);
    //If new filename already exists, delete it to write it anew.
    if (file_exists($newfile)) unlink($newfile);
    //Open new filename for writing
    $FileHandle=fopen($newfile,'w')
      or die("can't open file $newfile");
    //write the updated contents into the file
    fwrite($FileHandle,$str);
    //Close the new file
    fclose($FileHandle);
    //delete the old file
    unlink($filename);

Running the search and replace code on the Windows box blows up on the str_replace line with the following errors:

PHP Warning: Unexpected character in input: '\' (ASCII=92) state=1 in C:\Directory\test.php on line 117

PHP Parse error: parse error, unexpected T_STRING in C:\Direcotory\test.php on line 117

Why does windows not like this code, when it works just fine on linux?
