This is just a quick tip, but ever since discovering it I use it constantly. A lot of developers use PHP’s print_r() function to display human-readable information about a variable, which makes it great for debugging arrays and objects (among other things) very quickly. However, you have to wrap the output in <pre></pre> tags otherwise it gets spit out in a jumbled mess and doesn’t display nicely.
