How to format a php array

Question

I’m doing an SQL query in my model and in the controller, I’m printing the values of array.

The exhibition is like this:

Array ( [campo1] => 98 [campo2] => SOLO [soma] => 1 ) Array ( [campo1] => 92 [campo2] => DARTH [soma] => 11 ).

But I would like to format like this:

[campo1] => 98 =>[campo2] => 
            SOLO [soma] => 1
[campo2] => 92 =>[campo2] => 
            DARTH [soma] => 11

How to do?

This is my foreach:

foreach ($variavel1 as $key) {
   print_r($key);
}

Answer 1

If you want to see the contents of the array it is not necessary to run a foreach, just use the tag pre HTML together with the function print_r of PHP in this way:

echo '<pre>'.print_r($array, true).'</pre>';

The result will be:

Array
(
    [0] => Array
    (
        [campo1] => 98
        [campo2] => SOLO
        [soma] => 1
    )
    [1] => Array
    (
        [campo1] => 92
        [campo2] => DARTH
        [soma] => 11
    )

)

The tag pre has the objective of facilitating the reading of the data, preserving the spaces and line breaks returned by print_r.

And the function print_r when you have the second parameter reported as true instead of printing, returns the information so that we can use it as we wish.

Try Yii2’s own Vardumper user

\yii\helpers\VarDumper::dump($array, 10, true);

It’s a little different from the way you illustrated it, but that way it’s pretty clear

Answer 3

Let’s see you are printing a subarray that is found by for each if you want to print this way you will be no longer having an array and will have a string can do this by implode function

foreach ($variavel1 as $key) {
    $output = implode(', ', array_map(
        function ($v, $k) { return sprintf("[%s]=>'%s'", $k, $v); },
        $key,
        array_keys($key)
    ));
    echo $output."\n";
}

this will print something like

[campo1]=>'98', [campo2]=>'SOLO', [soma]=>'1' 
[campo1]=>'92', [campo2]=>'DARTH', [soma]=>'11'
