title: Converting Hex Codes into Characters
body: <p>Does PHP have a function that searches for hex codes in a string and converts them into their char equivalents? </p>
  
  <p>For example - I have a string that contains the following </p>
  
  <p>"Hello World\x19s"</p>
  
  <p>And I want to convert it to </p>
  
  <p>"Hello World's"</p>
  
  <p>Thanks in advance.</p>
