#13492 — how to join two arrays?

I am building an array by scannning ten directories.
With each scanned directory, the output is stored in one array.
How do I properly join that array with a second array?

Without duplicate keys!

Array_merge works fine but keys are duplicated.

Keys are always unique, see example:


<?php

$a1 = array("a" => 1, "b" => 2, "c" => 3);

$a2 = array("a" => 10, "d" => 4, "e" => 5);

$a3 = array_merge($a1, $a2);

var_dump($a1);
var_dump($a2);
var_dump($a3);

echo $a3["a"]."\n";

?>

If you haven't named the cells, then it will just merge the arrays 
(append one after the other).

scandir creates numerically indexed arrays. Merging these arrays will 
create a larger numerically indexed array, eg if you merge two arrays 
with keys [0] through [9], you end up with a single array with keys [0] 
through [19].

eg if the first dir generated:

$arr1

[0] "."
[1] ".."
[2] "foo.bar"
[3] "really fubar"

and the second dir generated

$arr2

[0] "."
[1] ".."
[2] "bah bah.blacksheep"
[3] "fufu.fubar"

then: array_merge ( $arr1, $arr2 );

will generate:

[0] "."
[1] ".."
[2] "foo.bar"
[3] "really fubar"
[4] "."
[5] ".."
[6] "bah bah.blacksheep"
[7] "fufu.fubar"

How you then tell which file is where, that's your headache at this point.

array_map() serves here.

And how can array_map() tell which file is where?

It cannot.  However, if you apply array_map() to the arrays returned by 
scandir() before merging them, the problem at hand does not occur in the 
first place:

$modi = max(
  array_map('filemtime',
    array_diff(
      array_merge(
        scandir(__DIR__),
        array_map(
          function ($e) {
            return 'sections' . DIRECTORY_SEPARATOR . $e;
          },
          scandir('sections')
        )
      ),
      array('.', '..')
    )
  )
);

Then why did you say it could?

What a convoluted mess.  Glad you're not working on any code I have to 
touch!

But then you always did have a knack for making a mountain out of a 
molehill.

You can't even read what you wrote...  Even though it's part of this 
message above, I'll repeat it for you:

I know what I wrote.  I also know that – granting you the benefit of a 
doubt one more time – you are not trolling, but that you have misinterpreted 
what I wrote.  I have written (as can be read in the quotation above, so 
there is no need for you or me to repeat it below) that “array_map() serves 
here”.  It does.  I have, upon your query, given an example showing what I 
meant with “serves here” from a real-life example (hence “here”).  
Apparently you have not bothered to understand the example, as you had 
decided to deride it in yet another ad-hominem fallacy of yours.

I have made myself clear now to all who can read carefully and think 
clearly.  Further misinterpretation on your part will be considered 
deliberate, aka trolling, and dealt with accordingly.

There was nothing to misinterpret.  array_map() does Not solve the 
problem of "How you then tell which file is where, that's your headache 
at this point.", which is the question it is response to.

But we already know you're too stoopid to understand, and too 
egotistical to admit you screwed up (again).

And yes, you made yourself clear.  You proved you have no idea how to 
solve this problem.

So, do everyone a favor and find another newsgroup to troll.  You're 
know as one in enough newsgroups that shouldn't be a problem.

As for suggestion someone else is a troll?  That is the best laugh I've 
heard of all year.  It's even better than suggesting Richard is competent.

Looking over my last comment, I have to apologize.  It wasn't fair to 
Richard.  Sorry, Richard, I shouldn't have insulted you like that.

$lo=0;
$hi=0;

for ($i = 59; $i <= 69; $i++) {
	$yr="19$i";
    echo $i;
	echo $yr;
	echo "<br>";

$dir='../audio/'.$yr.'/';
$files = scandir($dir);
$number=count($files);
echo $number;
echo "<br>";
sort($files);
$hi=$hi+$number;
echo $hi;
echo "<br>";

for ($x=0;$x<=$number;$x++){echo $files[$x];
     $master[$lo]=$files[$x];
	 $lo=$lo+1;

}
$lo=$hi;
}

for ($x=0;$x<=$hi;$x++){echo $master[$x]."<br>";}

the echos are there primarily to show what the progress is.
they will be removed for final output.

Questio I have now is, how do I get it so the leading "." and ".." are not
in the final array?
I tried using a conditional with !="." and that did not work.

Richard,

If written correctly a conditional for !="." would get rid of the '.' 
entry; !=".." would get rid of the ".." entry.

But you didn't show your entire code, so it's hard to say what could be 
wrong.

for ($x=0;$x<=$number;$x++){
 
  if ($files[x] !=".") {
   $master[$lo]=$files[$x];
	 $lo=$lo+1;
     }

You really need to find some what to work which lets you see all the
notices and warnings that PHP can give you.

By the way, writing $master[] = ... puts an element at the next unused
numerical index in the array which might be what you are doing here with
$lo.  I'd write the above like this:

  foreach ($files as $file)
       if ($file !== '.')
            $master[] = $file;

Thanks. Works like a charm.
Now how do I also include the ".."?
  foreach ($files as $file) 
       if ($file !== '.' || $file!=="..")
            $master[] = $file;
This does not seem to work.

Time to implement the formidable goto eh?

I assume that it does what it should: it will append any file whose name
is not equal to '.' *or* not equal to '..', i.e. every file.  You want
to use the && operator here.

Another option which excludes all hidden files:

    if ($file[0] != '.')

Fortunately not.
