I'm doing it this way:

But I can not get the content under TextRun... any ideas?

@mr-pack another idea.
@Anexo You do not need to know it is a TextRun, just if it has a method called getText. Also, sinds elements can be nested, you need recursion:

function ExtractText($obj, $nested = 0){
	$txt = "";
	if(method_exists($obj, 'getSections')) {
		foreach ($obj->getSections() as $section) {
			$txt .= " " . ExtractText($section, $nested+1);
		}
	}else if (method_exists($obj, 'getElements')) {
		foreach ($obj->getElements() as $element) {
			$txt .= " " . ExtractText($element, $nested+1);
		}
	}else if (method_exists($obj, 'getText')) {
		$txt .= $obj->getText();
	}else if(method_exists($obj, 'getRows')) {
		foreach ($obj->getRows() as $row) {
			$txt .= " " . ExtractText($row, $nested+1);
		}
	}else if(method_exists($obj, 'getCells')) {
		foreach ($obj->getCells() as $cell) {
			$txt .= " " . ExtractText($cell, $nested+1);
		}
	}else if (get_class($obj) != "PhpOffice\PhpWord\Element\TextBreak"){
		$txt .= "(".get_class($obj).")"; # unknown object, you need to add it
	}
	return $txt;
}

$text = ExtractText($phpWord->load($filename));
$text = str_replace(' ',"", $text );
$text = str_replace('•',"",$text );
$textArray = preg_split('/\s+/', $text );
$numberWords = count($textArray);

This example is woefully incomplete though. Do not use it to count words. This is becausethe textrun's actually do not need the space at the beginning from the previous text, so extra markers need to be added to remove artificials spaces between words. Something like:
if (get_class($obj) == "PhpOffice\PhpWord\Element\TextRun") { $txt = "<bs>" . $txt; } which then are to be removed before returning (but only when nested==0)

@FBnil "You do not need to know it is a TextRun": the problem is with class PhpOffice\PhpWord\Element\Title, which can return a TextRun when getText() is executed:

class Title extends AbstractElement
{
    // [...]

    /**
     * Create a new Title Element
     *
     * @param string|TextRun $text
     * @param int $depth
     */
    public function __construct($text, $depth = 1)
    {
        if (is_string($text)) {
            $this->text = CommonText::toUTF8($text);
        } elseif ($text instanceof TextRun) {       // <-- THIS IS THE PROBLEM
            $this->text = $text;                    // <-- THIS IS THE PROBLEM
        }
        // [...]
    }

    /**
     * Get Title Text content
     *
     * @return string
     */
    public function getText()
    {
        return $this->text;
    }

    // [...]

}

Here's my solution, which extends yours:

function ExtractText($obj, $nested = 0) {
        $txt = "";
        if (method_exists($obj, 'getSections')) {
            foreach ($obj->getSections() as $section) {
                $txt .= " " . ExtractText($section, $nested + 1);
            }
        } else if (method_exists($obj, 'getElements')) {
            foreach ($obj->getElements() as $element) {
                $txt .= " " . ExtractText($element, $nested + 1);
            }
        } else if (method_exists($obj, 'getText')) {
            // --------------------------------------------------------------
            // THIS IS THE DIFFERENT BLOCK
            $extracted = $obj->getText();
            if (is_string($extracted) === true) {
                $txt .= $extracted;
            } else {
                $txt .= " " . ExtractText($extracted, $nested + 1);
            }
            // --------------------------------------------------------------
        } else if (method_exists($obj, 'getRows')) {
            foreach ($obj->getRows() as $row) {
                $txt .= " " . ExtractText($row, $nested + 1);
            }
        } else if (method_exists($obj, 'getCells')) {
            foreach ($obj->getCells() as $cell) {
                $txt .= " " . ExtractText($cell, $nested + 1);
            }
        } else if (get_class($obj) != "PhpOffice\PhpWord\Element\TextBreak") {
            $txt .= "(" . get_class($obj) . ")"; # unknown object, you need to add it
        }
        return $txt;
}

$text = ExtractText($phpWord->load($filename));
$text = str_replace(' ',"", $text );
$text = str_replace('•',"",$text );
$textArray = preg_split('/\s+/', $text );
$numberWords = count($textArray);

Hope this helps! :-)
