Replacing <br> with space in string using PHP

I am trying to replace a <br> with a space within a string in PHP, however it does not seem to work. How would I go about correcting what I did to make this work?

The line of code that I have tried is the following:

    $keyword = str_replace("<br>", " ", getTextBetweenTags($html, "h4", "ctlAuthor"));

The string that is being returned in code looks like the following:

Dörte Kreher<br>Humboldt-Universität<br>Institut für Mathematik

The string that is being return to the PHP page is the following:

Dörte KreherHumboldt-UniversitätInstitut für Mathematik

The desired string that should be returned to the PHP page:

Dörte Kreher Humboldt-Universität Institut für Mathematik

Here is the getTextBetweenTags() function:

function getTextBetweenTags($string, $tagname, $tagid)
{
    $dochtml = new DOMDocument();
    $dochtml->loadHTML($string);
    $prgs = $dochtml->getElementsByTagName($tagname);
    $pcls = array();

    foreach($prgs as $prg)
    {
        if ($prg->getAttribute('id') == $tagid){
            $pcls[] = $prg->nodeValue;
        }
    }
    return $pcls[0];
}

Because the strings are coming from the NodeValues of elements within a DOMDocument, the HTML needs to be preserved. In order to resolve this issue, the line of code:

$pcls[] = $prg->NodeValue;

Was replaced with:

$pcls[] = $prg->ownerDocument->saveHTML($prg);

And then the HTML tags were able to be replaced with the desired output as follows:

$keyword = str_replace("<br>", " ", getTextBetweenTags($html, "h4", "ctlAuthor"));

Why don't you use strip_tags? i.e:

$keyword = strip_tags(getTextBetweenTags($html, "h4", "ctlAuthor"));

strip_tags

Strip HTML and PHP tags from a string

string strip_tags ( string $str [, string $allowable_tags ] )

This function tries to return a string with all NULL bytes, HTML and PHP tags stripped from a given str. It uses the same tag stripping state machine as the fgetss() function.

https://php.net/strip_tags

Update based on your comments:

$string = "Dörte Kreher<br>Humboldt-Universität<br>Institut für Mathematik";
$notags =  preg_replace('/<[^>]*>/', ' ', $string );
echo $notags;

Output:

Dörte Kreher Humboldt-Universität Institut für Mathematik

Try with a non breaking space html

$keyword = str_replace("<br>", "&nbsp;", getTextBetweenTags($html, "h4", "ctlAuthor"));
