This is the order of processing, when you request a symfony page:
- the action is executed (this is where you put your var_dump)
- the actions template is rendered
- the output is decorated with the layout
I cannot think of any way you could execute your code after the last
step - as far as I understand you want to do this.
I recommend you put your var_dump in the template (second step above)
- it's not the bottom of the page, but it's good enough, it's only for
debugging anyway.
