I just wrote the following line of code. And it’s no mistake: it functions perfectly and does exactly what I wanted it to do:<\/p>\n
$count += 0;<\/tt><\/p>\n
This is surely poor programming practice, essentially implicitly recasting a variable as an integer. But it’s simple and it works flawlessly. (The context: I run an SQL query saying SELECT SUM(votes)...<\/tt>, which makes the tabulation of all the entries MySQL’s problem, not mine. The one ‘flaw’ is that the sum of no votes isn’t 0, but NULL. This becomes a very important distinction when you’re trying to display a number: “0 votes” isn’t the same as ” votes.”)<\/p>\n
Since we all know that NULL + 0 = 0 (and, of course, integer + 0 = integer), adding 0 works flawlessly. Could I just convert it to an integer? Probably. But I haven’t done that stuff in a while, and I was far too lazy to pull up the documentation. And incrementing a variable by 0 is way more fun.<\/p>","protected":false},"excerpt":{"rendered":"
