来自PHP的HTML有一些不受欢迎的过度缩进

Question

I'd like to control exactly the indentation of my HTML that's generated by PHP but I'm unable to remove some of it. An example is this HTML source code:

<table id="structure">
<tr>
    <td id="navigation">
        <p>Hello!</p>   </td>

Why are the <td> and <p> lines indented like this? Can I modify that?

The main PHP that generated it was

<table id="structure">
<tr>
<td id="navigation"><?php echo navigation($data_page,$data_subj);?>

and the "navigation" function starts with

function navigation($data_page,$data_subj){
$output = "<p>Hello!</p>";
return $output;
}

(The real navigation is a <ul> with <li> elements containing <ul>'s in turn and I'm trying to render it readable in the HTML source code by adding and \t\t for indentation levels.)

For new line try ' '. The sign for new line is depends on your file encoding and the operating system you are using.
