You could try something like:
<?php
$sourcecode = 'echo "1";if(FALSE){echo 2;echo 2; echo 2; if(TRUE){echo 3;}}echo 4;';
$sourcecode = "<?php\n{$sourcecode}\n?>\n";
$indentlevel = 0;
$output = '';
foreach(token_get_all($sourcecode) as $token)
{
if (is_array($token))
list($tokentype, $spelling) = $token;
else
list($tokentype, $spelling) = array(NULL, $token);
if ($tokentype==T_WHITESPACE && preg_match('/\s$/', $output))
{
continue;
}
elseif ($spelling=='{')
{
$indentlevel++;
}
elseif ($spelling=='}')
{
$indentlevel--;
$output = preg_replace('/\t$/i', '', $output);
}
$indent = str_repeat("\t", $indentlevel);
$output .= $spelling;
if ($spelling==';'||$spelling=='{'||$spelling=='}')
$output .= "\n$indent";
}
print $output;
?>
