I am doing a SQL query in my model and controller , I am printing the array values.
The view looks like this:
Array ( [campo1] => 98 [campo2] => SOLO [soma] => 1 ) Array ( [campo1] => 92 [campo2] => DARTH [soma] => 11 ).
But I would like to format it like this:
[campo1] => 98 =>[campo2] =>
SOLO [soma] => 1
[campo2] => 92 =>[campo2] =>
DARTH [soma] => 11
How to do it?
This is my foreach :
foreach ($variavel1 as $key) {
print_r($key);
}
Let's see that you are printing a subarray that is found by for each if you want to print this way you are no longer having an array and have a string you can do this by the implode function
foreach ($variavel1 as $key) {
$output = implode(', ', array_map(
function ($v, $k) { return sprintf("[%s]=>'%s'", $k, $v); },
$key,
array_keys($key)
));
echo $output."\n";
}
This will print something like
[campo1]=>'98', [campo2]=>'SOLO', [soma]=>'1'
[campo1]=>'92', [campo2]=>'DARTH', [soma]=>'11'
If you want to see the contents of the array it is not necessary to execute a foreach , just use the pre of HTML tag in conjunction with the print_r function of PHP like this:
echo '<pre>'.print_r($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 pre tag is intended to make it easier to read the data, preserving the spaces and line breaks returned by print_r .
And the function print_r when it has the second parameter informed as true instead of printing, returns the information so we can use as we wish.
Try user Yii2's own VarDumper
\yii\helpers\VarDumper::dump($array, 10, true);
It's a bit different from the way it's illustrated, but that way it's very clear
