Inspect object in PHP
To display the contents of an object in ruby is really simple.
All you do is store the object in a variable, then pass the variable as an argument to the Kernel method
p(), which in turn writes
obj.inspect to the standard output.

I was recently doing something in WordPress where it would have been really useful to see the contents of an object I was fetching.
Here’s how I solved the problem:
This does what it should, but I still think the ruby way is less cumbersome though …
N.B. Also useful was PHP’s count() function, which returns the length of an array.
This is documented here: http://phparraylength.com/
Edit: since getting a bit more into PHP, I have discovered the nifty function
print_r(), which outputs human-readable information about a variable. You can read more about this here: http://php.net/manual/en/function.print-r.php
