Question

I have two functions that i’m hoping i can put into one and can be called differently.

function my_function() {    
global $wpdb;
foreach( $wpdb->get_results( "MYSQL QUERY" ) as $key => $row)
{
    echo "'". $row->DAY . "'";
}
}

function my_function_two() {    
    global $wpdb;
    foreach( $wpdb->get_results( "MYSQL QUERY" ) as $key => $row)
    {
        echo "'". $row->TIME . "'";
    }
}

Notice how the only diffence between them both is the $row->TIME and $row->DAY, i’m using the exact same mysql query in both and was wondering if these two functions can be merged into one?

Thanks for help.

You can do:

function my_function($showDay = false) {    
  global $wpdb;
  foreach( $wpdb->get_results( "MYSQL QUERY" ) as $key => $row)
  {
    echo "'". ($showDay === true) ? $row->DAY : $row->TIME . "'";
  }
}

If you have to echo $row->DAY, call the function with true as parameter or leave it out to echo $row->TIME.

Example:

my_function(true); // for $row->DAY
my_function(); // for $row->TIME
