PHP If loop for ACF with search for text value

Question

I created the following if loop with php (I'm a php beginner), with which I can search for a specific search term in the text in an ACF textfield and output a text depending on the result:

This is my code for finding one keyword only and it works fine:

$text = get_field('my_acf_field');
$keyword = "text";

$result = strpos($text, $keyword);

if($result === false) {
   echo "Text not found";
} else {
   echo "Text found";
}

This works perfectly. Now I would like to extend the code to have several search words output differently. So something along the lines of:

$text = get_field('my_acf_field');
$keyword1 = "text";
$keyword2 = "text 2";
$keyword3 = "text 3";

$result = strpos($text, $keyword1, $keyword2, $keyword3);

if($result === $keyword1) {
   echo "Lorem Ipsum 1";
} elseif($result === $keyword2) {
   echo "Lorem Ipsum 2";
} elseif($result === $keyword3) {
   echo "Lorem Ipsum 3";
} else {
   echo "Text not found";
}

However, that doesn't work and I can't find my mistake.

Thank you for your help

$foundKeywords = [];
foreach ([$keyword1, $keyword2, $keyword3] as $keyword) {
  if (strpos($text, $keyword) !== false) {
    echo 'Found keyword: ' . $keyword;
    $foundKeywords[] = $keyword;
  }
}
if (empty($foundKeywords)) {
  echo 'No keywords found';
}
