How to convert `if condition` to `switch` method

Question

How can I write this if condition in switch method?

if( $k != \'pg_id\' && $k != \'pg_tag\' && $k != \'pg_user\' )
{
           


        

Answer 1

A switch condition is likely to be faster (jump table) and a bit easier to read. You can skip the break; if the result of the condition is the same and an improved syntax is to use curly braces inside each condition:

switch ($k)
{
 case 'pg_id':
 case 'pg_tag':
 case 'pg_user': {
 break;
 }
 default: {
   $result = $connection->run_query($sql,array(...));
 }
}
