Question

I am having trouble pulling elements out of this multi-dimensional array?

Here is my code below:

$ShowTables = $Con->prepare("SHOW TABLES");
$ShowTables->execute();
$ShowTResults = $ShowTables->fetchAll();

If I print_r($ShowTResults); I get this multi-dimensional array:

Array (
    [0] => Array ( [Tables_in_alltables] => userinformation [0] => userinformation )
    [1] => Array ( [Tables_in_alltables] => users           [0] => users ) 
) 

Foreach new table is loaded it adds another dimension of the array. I want to pull each of the table names, out of the multi-dimensional array into a new array which I can use for future plans.

Would anyone have any ideas?

I have tried 1 foreach Loop; but this served no justice.

You want to fetch all results of the first column in form of an array:

$ShowTResults = $Con->query("SHOW TABLES")->fetchAll(PDO::FETCH_COLUMN, 0);
print_r($ShowTResults);

This gives you:

Array (
    [0] => userinformation
    [1] => users
) 

Which I think is what you’re looking for.

Another variant (a bit more complicated, but fitting for similar but little different cases) is to fetch the results as function (PDO::FETCH_FUNC) and directly map the result:

$ShowTResults = $ShowTables->fetchAll(PDO::FETCH_FUNC, function($table) {
    return $table;
});
