array_push() one value into multiple arrays

Question

I realize this may be a very simple question but I need to know how to add ONE value to multiple arrays in PHP. (The better way)

array_push($one, "hello");
array_push($two, "hello");

I need to do something like this (just as an example)

array_push($one && $two, "hello");

I have read through this question and seen the discussion if whether $array[] is better for speed, is it easier to use $array[] for my specific problem?

Thanks in advance!! && please ask for any clarification needed!

I think the best way to do it would be...

$one[] = $two[] = 'hello';

It works!

Update

BTW Any answers using array_push? – Trufa

Sure.

$value = 'hello';
array_push($one, $value);
array_push($two, $value);

Though I would say using the [] syntax is easier :)

If you want to add multiple array members, it may be easier to use array_merge().

$one = array_merge($one, array(
   'a',
   'b',
   'c'
));

You can also use the + array operaror, but it acts different (e.g. won't overwrite string keys from the left operand like array_merge() will).

$one += array(
   'a',
   'b',
   'c'
);

Alex thanks, but I´m actually doing that (in my code, the "hello" is just an example) for the array_push I just wanted to see if I could do it in one line, or most importantly using only ONE array_push

@Trua array_push() lets you append multiple members, but doesn't let you append those multiple members to multiple arrays on its own. It takes a reference to one array only.

Why does it have to be on one line? The below code works and is very readable:

$value = 'hello';
$one[] = $value;
$two[] = $value;

Your delimiters for the string do not match (', ") - maybe you copied and pasted mine when I did the same thing first :P

catchdave Over a year ago

I did copy/paste it to start with. Was working on other solutions (a loop over arrays, etc), then noticed the author seemed happy with your answer . I still don't see the point of this question - why does he "need" to put things on one line. I think readability always trumps saving lines of code.

Thanks, I wanted to "put it in one line" because I´m actually using array_push() so I didn't want to call it several times in different consecutive lines...

Yeah, readability is generally the most important thing. But I feel doing it like in my answer doesn't harm the readability much. Plus, you can skip the $value variable. :) +1 for your valid point of view.

the thing is that you answered my question using $array[] which makes it simple to add one value to multiple arrays but if i were to use the array push, I would have to do: array_push($one, "hello"); array_push($two, "hello"); ten times, this doesn't seem to make a lot of sense to me, maybe its readable but its not very "nice"...

try $one[] = $two [] = "hello";

@Trua I think it is fair to say that they probably didn't see my answer when posting.
