Debugging / Backtracing

Note: You are currently reading the documentation for Bolt 3.7. Looking for the documentation for Bolt 5.2 instead?

Using this function you can get a backtrace through the code to the current point in the execution. Useful for when you're debugging something, and you're not quite sure how you got here to begin with.

Twig¶

In your templates, use the following:

    {{ backtrace() }}

PHP¶

In your code you can also use backtrace, like this:

    use Symfony\Component\VarDumper\VarDumper;

    VarDumper::dump(debug_backtrace());

Or, using the (global) shortcut:

    dump(debug_backtrace());

The optional parameters denotes the options and maximum depth of the output of the backtrace. See the page on php.net: debug-backtrace.php().
