title: Simple PHP string replace?
body: <p>I have this code:</p>
  
  <pre><code>$abc = ' Hello "Guys" , Goodmorning';
  </code></pre>
  
  <p>I want to replace every occurrence of <code>"</code> (double quotes) by <code>$^</code> so that string becomes</p>
  
  <pre><code>'Hello $^Guys$^ , Goodmorning'
  </code></pre>
  
  <p>I am new to PHP; in Java we can do this very easily by calling the string class <code>replaceAll</code> function, but how do I do it in PHP? I can't find the easy way on Google without using regular expressions.</p>
  
  <p>What is some syntax with or without the use of regular expressions?</p>
