Simple PHP Configuration/Database Functions

[Doomguy0505]

These are an alternative to databases and are more effective than ini files because they can have newlines and carriage returns.

EDIT: Reading bug fixed
Here's the code

<?php
function Escaped($escapedata)
{
	$tempdata = $escapedata;
	$tempdata = str_replace("\\", "\\\\", $tempdata);
	$tempdata = str_replace("\n", "\\n", $tempdata);
	$tempdata = str_replace("\r", "\\r", $tempdata);
	$tempdata = str_replace("\t", "\\t", $tempdata);
	return $tempdata;
}
function UnEscaped($escapedvalue)
{
	$linedata = str_split($escapedvalue);
	$curchar = "";
	$escapedmode = 0;
	$cnt = count($linedata);
	$alldata = "";
	for($i=0;$i<=$cnt;$i++) 
	{
		$curchar = $linedata[$i];
		if ($escapedmode == 1)
		{
			switch ($curchar)
			{
				case "\\":
					$alldata = $alldata . "\\";
				break;
				case "n":
					$alldata = $alldata . "\n";
				break;
				case "r":
					$alldata = $alldata . "\r";
				break;
				case "t":
					$alldata = $alldata . "\n";
				break;
			}
			$escapedmode = 0;
		}
		else
		{
			if ($curchar == "\\") { $escapedmode = 1; continue; }
			$alldata = $alldata . $curchar;
		}
	}
	return $alldata;
}
function Cfg_GetKey($data, $ind, $subind)
{
	$linedata = split("\n", $data);
	$specificline = $linedata[$ind];
	$splitdata = split("\t", $specificline);
	$rldata = UnEscaped($splitdata[$subind]);
	return $rldata;
}
function Cfg_WriteKey($data, $ind, $subind, $setdata)
{
	$linedata = split("\n", $data);
	$specificline = $linedata[$ind];
	$splitdata = split("\t", $specificline);
	$splitdata[$subind] = Escaped($setdata);
	$nld = implode("\t", $splitdata);
	$linedata[$ind] = $nld;
	$retval = implode("\n", $linedata);
	return $retval;
}
function Cfg_IndCount($data)
{
	$dat = split("\n", $data);
	return count($dat);
}
?>

Here's a useful function so that the user doesn't reformat your web page with comments/input.

Converts text writing to html formatting.

function CHTML($data)
{
$newdata = $data;
$newdata = str_replace("&", "&", $newdata);
$newdata = str_replace(";", ";", $newdata);
$newdata = str_replace(" ", " ", $newdata);
$newdata = str_replace(">", ">", $newdata);
$newdata = str_replace("<", "&lt;", $newdata);
$newdata = str_replace("/", "&frasl;", $newdata);
$newdata = str_replace("\n", "", $newdata);
$newdata = str_replace("=", "=", $newdata);
return $newdata;
}
