Simple: How to replace “all between” with php? [duplicate]

Answer 1

If you need to replace the portion too then this function is helpful:

$var = "Nate";

$body = "Hey there {firstName} have you already completed your purchase?";

$newBody = replaceVariable($body,"{","}",$var);

echo $newBody;

function replaceVariable($body,$needleStart,$needleEnd,$replacement){
  while(strpos($body,$needleStart){
      $start = strpos($body,$needleStart);
      $end = strpos($body,$needleEnd);
      $body = substr_replace($body,$replacement,$start,$end-$start+1);
  }
  return $body;
}

I had to replace a variable put into a textarea that was submitted. So I replaced firstName with Nate (including the curly braces).
