note 78060 added to function.parse-ini-file

I need to read a ini file, modify some values in some
sections, and save it. But the important thing is, i want to
keep all the comments, the new lines in the right order. So
i modified function parse_ini_file_quotes_safe and
write_ini_file.
I think they work fine.

	function read_ini_file($f, &$r)
	{
		$null = "";
		$r=$null;
		$first_char = "";
		$sec=$null;
		$comment_chars=";#";
		$num_comments = "0";
		$num_newline = "0";

		//Read to end of file with the newlines still attached
into $f
		$f = file($f);
		if ($f === false) {
			return -2;
		}
		// Process all lines from 0 to count($f)
		for ($i=0; $i<count($f); $i++)
		{
			$w=trim($f[$i]);
			$first_char = substr($w,0,1);
			if ($w)
			{
				if ((substr($w,0,1)=="[") and (substr($w,-1,1))=="]") {
					$sec=substr($w,1,strlen($w)-2);
					$num_comments = 0;
					$num_newline = 0;
				}
				else if ((stristr($comment_chars, $first_char) == true))
{
					$r[$sec]["Comment_".$num_comments]=$w;
					$num_comments = $num_comments +1;
				}				
				else {
					// Look for the = char to allow us to split the section
into key and value
					$w=explode("=",$w);
					$k=trim($w[0]);
					unset($w[0]);
					$v=trim(implode("=",$w));
					// look for the new lines
					if ((substr($v,0,1)==""") and (substr($v,-1,1)==""")) {
						$v=substr($v,1,strlen($v)-2);
					}
					
					$r[$sec][$k]=$v;
					
				}
			}
			else {
				$r[$sec]["Newline_".$num_newline]=$w;
				$num_newline = $num_newline +1;
			}
		}
		return 1;
	}

	function write_ini_file($path, $assoc_arr) {
		$content = "";

		foreach ($assoc_arr as $key=>$elem) {
			if (is_array($elem)) {
				if ($key != '') {
					$content .= "[".$key."]rn";					
				}
				
				foreach ($elem as $key2=>$elem2) {
					if ($this->beginsWith($key2,'Comment_') == 1
&& $this->beginsWith($elem2,';')) {
						$content .= $elem2."rn";
					}
					else if ($this->beginsWith($key2,'Newline_') == 1
&& ($elem2 == '')) {
						$content .= $elem2."rn";
					}
					else {
						$content .= $key2." =
".$elem2."rn";
					}
				}
			}
			else {
				$content .= $key." =
".$elem."rn";
			}
		}

		if (!$handle = fopen($path, 'w')) {
		    return -2;
		}
		if (!fwrite($handle, $content)) {
		    return -2;
		}
		fclose($handle);
		return 1;
	}

	function beginsWith( $str, $sub ) {
		return ( substr( $str, 0, strlen( $sub ) ) === $sub );
	}
