関数b（）が失敗したときに関数a（）を終了します

Question

この問題をどのように解決するのか少し混乱します。 createSubaccount関数が失敗した場合、私たちはコード内でcreatesite関数を実行したくありません。私たちは、コードに関するフィードバック、コメント、ガイドを本当に感謝しています。

<?php 
//Set API user and password 
define("API_USER","user"); 
define("API_PASS","pw"); 

    $createdSite = createSite($_REQUEST['template_id'],$_REQUEST['original_url']); 
    //echo 'Site Created: ' . $createdSite . '<br/>'; 
    $accountCreated = createSubAccount($_REQUEST['email']);//client email 
    //echo 'Account created: ' . $accountCreated . '<br/>'; 


    $first_name = $_REQUEST['first_name'];//First Name 
    $last_name = $_REQUEST['last_name'];//Last Name 

    $retArr = ["sso"=>$sso_link,"ru"=>$resetURL,"ac"=>$accountCreated,"fn"=>$first_name,"ln"=>$last_name];//assoc array 

    print json_encode ($retArr);//json string 


function createSite($template_id,$original_url) { 
    //create array with data 
    if($original_url) { 
     $data = array("template_id"=>$_REQUEST['template_id'],"url"=>$original_url);  
    } else { 
     $data = array("template_id"=>$_REQUEST['template_id']); 
    } 
    //turn data into json to pass via cURL 
    $data = json_encode($data);

    $last_name = $_REQUEST['last_name'];//Last Name 
    $data = '{"account_name":"'.$emailToCreate.'", "first_name":"'.$first_name.'", "last_name":"'.$last_name.'"}'; 

    $ch = curl_init(); 
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); 
    curl_setopt($ch, CURLOPT_URL, 'https://api.website.com/api/create'); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

     curl_close($ch);

    } else { 
     curl_close($ch);

これはExceptionが便利な場所です。

function createSite() { 
    throw new \Exception('Failed'); 
} 

try { 
    $createdSite = createSite($_REQUEST['template_id'],$_REQUEST['original_url']); 
    //echo 'Site Created: ' . $createdSite . '<br/>'; 
    $accountCreated = createSubAccount($_REQUEST['email']);//client email 
} catch(\Exception $err) { 
    echo $err->getMessage(); 
} 

Exceptionは、ブロック内の残りのコードが一度スローされるのを防ぎます。
