I think mine would be json_encode()
. I think it's so cool that a single function can make your data understood by other machines. (I know other machines can interpret different kinds of data, but c'mon...)
How about you? What's your favourite function?

Reference
Based on usage it's probably
console.log()
orvar_dump()
.At the moment I'm enjoying some JavaScript array methods -
filter
,map
,reduce
.var_dump (); die ()!!!
I usually do like:
die(var_dump());
I stopped doing this simply because I can't do it if I dump multiple variables at once.
But you could do
die(var_dump($res, $res2));
, couldn't you?You can
Really? Wow, #TIL!
Yeah, just like
console.log(var1, var2)
in JStypeof(arg);
surprisingly useful
random()
functions, there is so much more behind them then we usually think. I can talk hours about entropy and sources, techniques, pseudo algorithms and how can it improve almost any software product.Improve in what way?
In the way of randomized algorithms
As in, some product features can be improved using random (shuffle or generate things), most basic example is chose new 5 news headlines to see from the top 100 articles to an user, each x seconds/page views.

🤣
Because it took me almost half a year to realize that it's a function, not a language construct.
Arrow function 🤓.
this
has never been easier.mine is fmap ...
fmap :: (a -> b) -> F a -> F b
with F being a Functor :-)
I find this one, truly comforting for some reason.
I like map.put and map.get. Maps/Dictionaries are incredibly useful data structures that we tend to take for granted nowadays.
Don't know if it's only a function, but ajax in Javascript is something else: the whole idea of a function connecting asynchronously to a server and retrieving data without the need of recharge the entire page is amazing.
describe
s,it
s,beforeAll
s, etc in Jasmine tests without actually caring about the legit expectations yet.map, filter, reduce, forEach, Array.prototype.some, Array.prototype.every
Working with array in Javascript never been easier.
Love it all!
Agreed, high order functions are best
Love throwing exceptions around ;)
In PHP I always include file with my custom helper functions. These two wrap output with
<pre/>
tags, which allows nice&quick debugging via browser from any class or template code.var_masterpiece is also an excellent browser extension too for debugging!
HA! I have a pre() function too! I use it many, many times a day. Mine has the $obj, but then a title, so if I have multiple pre()s going, I know which is which. Like, pre( $obj, 'This is the user obj');
Love it.
In Ruby, backticks are a function call. And what's especially cool is that heredocuments with backticks call the same function, but with multi line arguments. So you can define them to do other, more interesting things, like call out to other languages! In practice, I mostly use it when experimenting with some slightly tedious external resource, I basically learned PostgreSQL by running them through these kinds of functions.
