PHP preg_replace three times with three different patterns? right or wrong?

Question

A simple question: Is this the best way to do it?

$pattern1 = \"regexp1\";
$pattern2 = \"regexp2\";
$pattern3 = \"regexp3\";

$content = preg_replace($patter         


        

Answer 1

I am using it for XML tags string.

Ahmad MaaropCJ, Zaharah Ibrahim, Prasad Sandosham, Jeffrey Tan, Alizatul Khair FCJJ\r\n';
 $patterns = array('/\bCJ\b/', '/\bJCA\b/','/\bJJCA\b/','/\bPCA\b/', '/\bCJM\b/', '/\bCJSS\b/', '/\bFCJ\b/', '/\bFCJJ\b/', '/\bJ\b/','/\bH\b/', '/\bPK\b/','/\bJC\b/', '/\bHMP\b/', '/\bHHMP\b/', '/\bHMR\b/', '/\bHHMR\b/');
 $replacements = array('CJ', 'JCA','JJCA','PCA', 'CJM', 'CJSS', 'FCJ', 'FCJJ', 'J','H', 'PK','JC', 'HMP', 'HHMP', 'HMR', 'HHMR');

   


  $string = preg_replace($patterns,$replacements,$xmlString);
  
  
  echo $string;
// Ahmad Maarop CJ, Zaharah Ibrahim, Prasad Sandosham, Jeffrey Tan, Alizatul Khair FCJJ\r\n ◀
