twigHow to debug using PHP and Twig?

Debugging using PHP and Twig can be done by using the debug function. This function will output the contents of a variable in a human-readable format. For example:

$data = array('name' => 'John', 'age' => 25);
echo debug($data);

Output example

Array
(
    [name] => John
    [age] => 25
)

The debug function can be used to inspect the contents of a variable, such as an array or object. It can also be used to inspect the contents of a Twig template, such as the variables and functions available.

To debug a Twig template, the dump function can be used. This function will output the contents of a variable in a human-readable format, similar to the debug function. For example:

{{ dump(data) }}

Output example

Array
(
    [name] => John
    [age] => 25
)

The dump function can be used to inspect the contents of a variable, such as an array or object, within a Twig template.
