When are you echoing $uuid?
The syntax looks good to me but you can try another syntax. The difference below is that the variables are in-line and not concatenated. You can do this with php as long as you use double-quotes. Also, the curly brackets are not necessary but if you use them they guarantee the variables name. see: When to wrap curly braces around a variable :

<?php
$uuid = trim(str_replace(' ', '', $dmid));
$now = date('Y-m-d h:i:s');
echo $uuid;
$establish = "\n\n START -- {$now} serial-no: {$uuid},if:{$res_value['if']}\n";
file_put_contents('filter.log', $establish);
?>
