Question

This is probably going to sound like a sci-fi request, though – is there a way to return to the beginning of the try {} block where Exception was thrown from within the catch() {} block?

Here is an example:

try
{
    // make OAuth request
}
catch(OAuthException $e)
{
    // if(){}
    // If tells me that the Exception was thrown because the access token is expired
    // I have alternative access token (that's always up to date, but there is a catch why I void using it)
    // I set it as a new access token and want to repeat the try {} block
}

Obviously goto could do it, though, I am looking if there is a more sophisticated approach.

Answer 1

You can wrap the code up inside a function and call the same function from the catch section

function remotePost($accessToken){

  try{

  }catch(OAuthException $e){
  //the one used is not alternative token and if there is an alternative access token
    return remotePost($alternativeAccessToken);
  }
}
