Flat File Text database

Anon

Does anyone have code samples for creating/reading/writing text files?

My web host is running php3

Anon

Here is a simple sample (guestbook):

Output like this:
<?php
include("domain\cgi-local\guestbook.txt"); ?>

Input via a form.

<?php

$gbuch="guestbook.txt";
if (!file_exists($gbuch)){
	$igbuch = fopen($gbuch,"w");
	fclose ($igbuch);
}

if (isset($name)){
	$tmpgbuch = @fopen($gbuch.".tmp","w");
	if ($tmpgbuch <= 0) {
		?>
			Zugriffsfehler auf dem Server, bitte versuchen Sie es nochmal.
		<?php
	}
	$text = ereg_replace( "&#10;", "<br>", $text );
	$text = htmlspecialchars($text);
	$datum = date("d.m.Y H:i:s");
	$eintrag= "<pre><font face=\"Verdana,Geneva\" size=\"2\"><B>Name:</B> $name<BR>";
	$eintrag.="<B>Email: </B><A HREF = \"mailto:$email\">$email</A><BR>";
	$eintrag.="<B>Datum:</B> $datum<BR>";
	$eintrag.="<B>Kommentar:</B><blockquote><br>$text</blockquote>\n<HR  width=\"75%\"></font></pre>";

	fputs($tmpgbuch, $eintrag);
	$igbuch = @fopen($gbuch, "r");
	if ($igbuch <= 0) {
		?>
			Zugriffsfehler auf dem Server, bitte versuchen Sie es nochmal.
		<?php
	}
	while(!feof($igbuch)){
		$zeile = fgets($igbuch, 32000);
		fputs ($tmpgbuch, $zeile);
	}
	fclose($igbuch);
	fclose($tmpgbuch);
	unlink($gbuch);
	rename($gbuch.".tmp", $gbuch);
}

Ouch! That's inherently single-user. What do you
do if two people try to add entries at the same time?

Anon

Yes, you are right, its better if you use a real database like mysql.

Perhaps here you could change the status of the file while writing or reading.
(chmod ?)

The text for writing could saved somewhere else and waiting.

But i would say, better use a DB.

Anon

A separate file to lock when updating the text database would
probably work better.

Ok, newbie question here. I have looked high and low in all the resources that I have and can not for the life of me find the answer.

I am reading a file to the display using the following:
$parts= fgets($fp, 300);
echo $parts."<br>";
etc...

However, my file is delimited with the pipe "|". I know that adding \t will work with tab delimited, but no where can I find what to add for pipe, or comma, etc.

I'm trying to display a nicely formatted output, but...

Help??
