Word-Wrapping .txt files?

rheroux

I have a whole bunch of text files that need to be reformatted so that the horizontal length of the file is 80. Right now, when displayed in a web browser, some lines are aren't wrapped properly and it makes for an ugly display.

I tried doing this to automate the insertion of line breaks into the .txt files but all it did was delete the first 3 characters of the .txt file.

Anyhoo, here's the code:

$dir = "..//files//15000";
$blah = opendir($dir);
while (false !== ($file = readdir($blah))) {
if($file == "." || $file == "..")
{
}
else
	{
     $fp = fopen($dir . "//" . $file, "r+");

for ( $i = 0; $i < count($fp); $i++ ) {
		fwrite($fp, "\r\n");
}
}
}

Any help is appreciated.

Have you considered [man]word_wrap[/man]?

Heh, I just found that function actually. 🙂

Trying it now.

Just tried this and it didn't work.

<?
$dir = "..//files//15000";
$blah = opendir($dir);
while (false !== ($file = readdir($blah))) {
if($file == "." || $file == "..")
{
}
else
	{
     $fp = fopen($dir . "//" . $file, "r+");

for ( $i = 0; $i < count($fp); $i++ ) {
		fwrite($fp,wordwrap($fp[$i]));
}
}
}
?>

Anyone have any ideas...or can tell me what I'm doing wrong?

Well, you're not actually reading the file at all...
I suggest you go back and remind yourself of the difference between fread() and file(), because I think you've got them confused.

Ok, updated code and it works...kind of. It does wrap the text, however, it's taking all the text, wrapping it and then appending it to the text file. Which leaves me with two sets of the same characters within the text file; one wrapped and one unwrapped.

I guess what I need to know is how to manipulate the text without appending.

Thanks in advance.

$dir = "../files/19000";
$blah = opendir($dir);
while (false !== ($file = readdir($blah))) {
if($file == "." || $file == "..")
{
}
else
	{
	 $path = $dir . "/" . $file;
	 echo $path;
	 $fp = fopen($path, "r+");
	 $contents = fread($fp,filesize($path));
	 $wrap = fwrite($fp,wordwrap($contents));
}
}

Well, chalk it up to stubborness or something but I finally got it to work! 🙂

I had to rewind the file pointer, something I didn't think of before.

Ah well, here's the final code if anyone is interested.

$dir = "../files/13000";
$blah = opendir($dir);
while (false !== ($file = readdir($blah))) {
if($file == "." || $file == "..")
{
}
else
	{
	 $path = $dir . "/" . $file;
	 echo $path;
	 $fp = fopen($path, "r+");
	 $contents = fread($fp,filesize($path));
	 rewind($fp);
	 $wrap = fwrite($fp,wordwrap($contents),strlen($contents));
}
}

Glad you got it working; I'd've opened it for reading, read it, closed it, opened it for writing, written it, closed it.... yours is simpler! 🙂
