title: preg_replace successful or not
body: <p>Is there any way to tell if a preg_replace was successful or not?</p>
  
  <p>I tried:</p>
  
  <pre><code>&lt;?php
  
  $stringz = "Dan likes to eat pears and his favorite color is green and green!";
  $patterns = array("/pears/","/green/", "/red/");
  
  if ($string = preg_replace($patterns, '&lt;b&gt;\\0&lt;/b&gt;', $stringz, 1)) {
  echo "&lt;textarea rows='30' cols='100'&gt;$string&lt;/textarea&gt;";
  }else{
      echo "Nope. You didn't have all the required patterns in the array.";
      }
  
  ?&gt;
  </code></pre>
  
  <p>and yes, I looked at php docs for this one. Sorry about my stupid questions earlier.</p>
