    Here is an example you can refer to

    Define a replacetags function

    <?php
function replacetags($text){
  $text = htmlspecialchars($text);
  $text = preg_replace("/=/", "=""", $text);
  $text = preg_replace("/"/", """", $text);
  $tags = "/<(\/|)(\w*)(\ |)(\w*)([\\\=]*)(?|(")"""|)(?|(.*)?"(")|)([\ ]?)(\/|)>/i";
  $replacement = "<$1$2$3$4$5$6$7$8$9$10>";
  $text = preg_replace($tags, $replacement, $text);
  $text = preg_replace("/=""/", "=", $text);
  
  return $text;
 }
?>

    Use replacetags

    <?php
$string = "
Hello
<b>ITtutoria</b><br />
website for dev = as this<br />
<a href="https://ittutoria.net/question/php-preg-replace-all-samples/">The question about Php Preg Replace</a><br />

echo replacetags($string);
?>

  2. Here is a simple and easy to understand example

    <?php
$string = 'April 25, 2022';
$pattern = '/(\w+) (\d+), (\d+)/i';
$replace = '${1}1,$3';
echo preg_replace($pattern, $replace, $string);
