How to resolve deprecated website errors

if your website experiences problems when accessed, and error information appears such as "Deprecated: Array and String offset access syntax with curly braces is deprecated in/var/xxx/xxx/xx/xx/xxx on line xxxx"

To overcome these obstacles, you can follow these steps:

check again on which files are experiencing error information when accessing your website, for example, errors in the file a.php on line 135 with the following script contents

 : 

public function getRecordID(string $zoneID, string $type = '', string $name = ''): string
{    $records = $this->listRecords($zoneID, $type, $name);    if (isset($records->result{0}->id)) {        return $records->result{0}->id;    }    return false;
}

*for the error in the script in bold

please make changes to the marked script as follows

public function getRecordID(string $zoneID, string $type = '', string $name = ''): string
{    $records = $this->listRecords($zoneID, $type, $name);    if (isset($records->result[0]->id)) 
{        return $records->result[0]->id;
}    return false;

    }
*for improvements to the script in bold

After that click save, and please try again to access your website.
