添加＆＃160; 使用PHP进入xml

Question

I want to add triple spacing in my xml but browser is changing triple spacing to single. I have found   to be used to include spacing. I have a tab delimited text file and i am converting it to xml using php. In order to have triple spacing inside my title node i am doing like this.

 $xml->startElement('Products');
    while ($line = fgetcsv($fp, 0, "\t")) {

        $xml->startElement('Product');
        //replacing titlesingle space to triple space
        $title = str_replace(" ", "   ", $line[1]);
        $xml->writeElement('title', $title);
        .....
        $xml->endElement();
    }
    $xml->endElement();
}

But is   changed to   and title is something like this

<title>A&amp;#160;&amp;#160;&amp;#160;Test</title>

Basically php is changing & to amp but i want exact   so that i can have triple spacing in the title

<title>A   Test</title>

Any help??

It does not change the spacing. But in HTML/XML several whitespaces are usually (not always) rendered as a single space or a linebreak.

#160; is the non breaking space. One of the uses is to separate the parts of a phone number. You don't want one of the spaces in a phone number rendered as a linebreak.

The UTF-8 bytes for this character are \xC2\xA0.

$xml->writeElement('foo', "foo\xC2\xA0&\xC2\xA0bar");

If the XML document is encoding is ASCII, they will get encoded as entities.

$xml = new XMLWriter();
$xml->openMemory();
$xml->startDocument('1.0', 'ASCII');

$xml->writeElement('foo', "foo\xC2\xA0&\xC2\xA0bar");

$xml->endDocument();
echo $xml->outputMemory(TRUE);

Output:

<?xml version="1.0" encoding="ASCII"?>
<foo>foo&#160;&amp;&#160;bar</foo>
