Question

This code is only appending the last integer in the for statement. I’m trying to append $root_text for each value in the for statement. Is $root_text supposed to be an array? I’m only appending 1 value with $root->appendChild($root_text)

The code:

 <?php
$doc = new DOMDocument('1.0', 'iso-8859-1');

$root = $doc->createElement('test');
$doc->appendChild($root);

for($i = 1; $i <= 10; $i++) {

    $root_text = $doc->createTextNode($i);

}

$root->appendChild($root_text);

print $doc->saveXML();
?>

You’re currently assigning a new value to $root_text each time through the loop, retaining (and ultimately appending) only the node from the final iteration. Why not simply appendChild directly in the loop?

for($i = 1; $i <= 10; $i++) {
    $test = $doc->createElement('test');
    $test->appendChild($doc->createTextNode($i));
    $root->appendChild($test);
}
