Re: bug? file(), newline (\n) comparison

on my linux based system echo ord("\n"); is 10 which is 0A in hex. windows machings usually consider newline to be 0A0D or 0D0A mac's usually are 0D I would convert your file. I have to do this often with file uploads. // convert all 0A0D and 0D0A to 0A0A $data = str_replace(chr(13), chr(10), $data); // convert all 0A0A to 0A $data = str_replace(chr(10).chr(10), chr(10), $data); this will standardize it for you. -- Chris Lee lee@mediawaveonline.com ""Hannes Schmiderer"" <johannes.schmiderer@aon.at> wrote in message news:9dtv8b$cud$1@toye.p.sourceforge.net... Hi! $astrData = file($astrCounterFile[$i]); echo "|\n|<br>"; echo "|" . $astrData[0] . "|<br>"; echo "|" . $astrData[1] . "|<br>"; //$astrData[1] = "\n"; //echo "|" . $astrData[1] .

"<br>"; } I use 4.0.5 Win32 CGI, At the moment FTP at my host is down, so I cannot test it on another system. I have a textfile with line breaks and some empty lines in it. I read it with file() into an array. When I output the lines, I can see in the hex editor that the second line contains only a newline (0D 0A). When I output "\n" it is 0D 0A, too. The strange thing is, that, when I compare this array element (with the emtpy line) with "\n" It is never true! Not with strcmp, strncmp or <>. When I remove the comments (//) and set $astrData[1]="\n" explicit it works! Note that echo "|" . $astrData[1] . "|<br>"; befor and after the assignment have the same output (in hex editor). Is this a type problem, are newlines internaly handled differently to usual strings?
