[RESOLVED] str_replace(), ob_start() and UTF-8

**solitario** · Sep 24th, 2008, 09:02 AM

Hello all.
Trying to build an application which replaces strings within an html page with elements from an array.
I can't figure out what I'm doing wrong here. I've got an external file named ru.txt. It has Russian text in it, hopefully it will display here:

Code:

<?

	$txt[0]="что компания является";

?>

My index page, which includes the text file, looks like this:

Code:

<?php

	/* MAKE CERTAIN WE USE UTF-8 ENCODING */
		header("Content-type: text/html; charset=utf-8");

	/* INCLUDE THE APPROPRIATE LANGUAGE FILE */
		include_once('_includes/ru.txt');

	/* THE CALLBACK FUNCTION */
		function callback($buffer) {

			/* LOOP THROUGH THE ARRAY, MAKING THE APPROPRIATE REPLACEMENTS */
				for($i=0; $i<count($GLOBALS['txt']); $i++) {

					$buffer=str_replace('{txt_'.$i.'}',$GLOBALS['txt'][i],$buffer);

				}

			/* RETURN IT */
				return $buffer;
		}

	/* BEGIN THE OUTPUT OBJECT */
		ob_start("callback");

?><html>
	<head>
		<title>test</title>
		<meta http-equiv="Content-type" value="text/html; charset=utf-8">
	</head>
	<body>{txt_0}</body>
</html><?

	/* END THE OUTPUT OBJECT */
		ob_end_flush();

?>

I am getting an empty page (nothing within the body tags.)
Both files have been saved with UTF-8. If I hard-code the str_replace with something like "blah" it works fine. If I remove the whole callback procedure and echo the $txt[0] from the external file, it works fine.
Any clues as to what I'm doing wrong?
Muchos thanks.
