I have a result array like this:
$result = Array
(
[1] => Array
(
[0] => some value
[1] => some value
[2] => some value
)
[4] => Array
(
[0] => some value
[1] => some value
[6] => Array
(
[0] => some value
[8] => Array
(
[0] => some value
)
)
)
)
and I have a second array
$test = Array
(
[4] => Array
(
[6] => Array
(
[8] => Array
(
[0] = value to add
)
)
)
)
How can I update the $result array on base of keys from $test array without losing any key index.
The main point is $result can have any structure and is dynamically generated but the $test array will always have keys index(s) which will somewhat match the $result array.
The general PHP array combine merge and other functions don't provide desired results.
[Edit]
The point is my second array $test will decide the position of $result where the data will be added/merged.
Did you try using:
http://php.net/manual/en/function.array-merge-recursive.php
By add do you mean append or addition(sum)??
This should work for appending the data.

I'm trying to add an item to an array, but the arrays keep stacking over one another and it becomes unusable.
I have tried different methods and I can make it work if my input doesn't come from get_user_meta() and instead I create a custom string to test the array. But I need to load the meta so I can just add additional content into it.
$user_id = get_current_user_id();
$the_id = get_the_ID();
$continue_watching = get_user_meta($user_id,'continue_watching',false);
if ( !isset($continue_watching) ) {
$continue_watching = array();
}
$continue_watching[] = $the_id;
update_user_meta($user_id,'continue_watching',$continue_watching);
This is what is happening:
Array (
[0] => Array
(
[0] => Array
(
[0] => 16966
[1] => 16966
)
[1] => 11234
)
[1] => 16951
)
But I expected the output to look like this:
Array (
[0] => 11234
[1] => 16951
[2] => 16966
[3] => 16970
)
Update:
I have reset the array and this is the output just after $continue_watching = get_user_meta($user_id,'continue_watching',false);
Array
(
)
This is the output after $continue_watching[] = $the_id;
Array
(
[0] => 16955
)
After opening another page, this is the output after $continue_watching = get_user_meta($user_id,'continue_watching',false);
Array
(
[0] => Array
(
[0] => 16955
)
)
And this is the output after $continue_watching[] = $the_id;
Array
(
[0] => Array
(
[0] => 16955
)
[1] => 16957
)
After trying all the alternatives, it turned out to be a very simple solution. All I had to do was change the value from false to true inside the wordpress function get_user_meta($user_id,'continue_watching',false);
The "false" option was displaying the array inside another array, when I changed it to "true" the output was the array contained inside the variable alone.
I have this array $data :
Array
(
[0] => 86086
[1] => Arnel
[2] => Paras
)
Array
(
[0] => 86085
[1] => Arnely
[2] => Para
)
Array
(
[0] =>
)
How do i remove the bottom array that contains no values totally so it only contains :
Array
(
[0] => 86086
[1] => Arnel
[2] => Paras
)
Array
(
[0] => 86085
[1] => Arnely
[2] => Para
)
I have tried using array_filter($data, strlen) and it just does this :
Array
(
)
array_pop() pops and returns the value of the last element of array, shortening the array by one element and will do exactly what you describe. A.
array_shift() does the opposite (removes first element from array and returns the value)
array_pop() on PHP.net
So you can either do:
$firstVal = array_pop($data)
or just
array_pop($data)
depending on if you want the value back or not.
Might help.
array_values(array_filter($data))
I have array like below. I would like to push it to 0 element array.
$csvdata is contain original array $pushHeaderSpec variable is what i want to push into original array i have also tried array_merge but not work as expected merge well on output only but when i print original data in csv it is not there.i m generating $csvdata array first and then append this array on last.
Array
(
[Ruder] => no value need on this
[Glas] => no value need on this
[Not] => no value need on this
)
My Multidimention array look something like
Array
(
[0] => Array
(
[0] => Sort order
[1] => Sku
[2] => Title
)
)
Many more element on above array so i just want to merge my first array keys to this array on first element that is 0.
I did try using below code but it doesn't give me output what i want.
array_push($csvdata[0],array_keys($pushHeaderSpec));
Output from code
Array
(
[0] => Array
(
[0] => Sort order
[1] => Sku
[2] => Title
[3] =>array (
[0] => Ruder
[1] => Glas
[2] => Not
)
)
)
Expecting Output
Array
(
[0] => Array
(
[0] => Sort order
[1] => Sku
[2] => Title
[3] => Ruder
[4] => Glas
[5] => Not
)
)
It was just
foreach (array_keys($pushHeaderSpec) as $key => $value) {
array_push($csvdata[0],$value);
}
Is that what you are looking for ?
foreach ($pushHeaderSpec as $key => $val) {
$csvdata[0][] = $key;
}
I have an array, which is given below:
$test = Array
(
[0] => Array
(
[0] => stud 1
)
[1] => Array
(
[0] => stud 2
)
[2] => Array
(
[0] => stud 3
)
);
I want to add a common element to above array with out using loop. For example, I want to add "test" to each element of array. After adding "test", array will look like:
$test = Array
(
[0] => Array
(
[0] => stud 1
[1] => 'test'
)
[1] => Array
(
[0] => stud 2
[1] => 'test'
)
[2] => Array
(
[0] => stud 3
[1] => 'test'
)
);
Is there any way to add common element array with out using any kind of loop(for, foreach etc...)?
You can use array_map(), check the live demo
array_map(function($v){$v[] = 'test'; return $v;}, $array);
I know this must be a fairly simple question, but I haven't managed to stumble across an answer yet.
I have the following array
$qid[0][0]=1;
$qid[1][0]=2;
$qid[2][0]=3;
$qid[3][0]=4;
When I use print_r($qid) I get the following
Array (
[0] => Array ( [0] => 1 [1] => 0 )
[1] => Array ( [0] => 2 )
[2] => Array ( [0] => 3 )
[3] => Array ( [0] => 4 )
)
I don't understand [1] => 0
in
[0] => Array ( [0] => 1 [1] => 0 )
If someone could explain what [1] => 0 means in this array, I'd greatly appreciate it. Thanks.
EDIT: It turns out that my array was indeed different to what I had written above, because it had been modified later in the code. Thanks everyone for the great answers. I'm still reading over them all and trying to make my mind understand them (Arrays turn my mind to jello).
[1] => 0 denotes an array element with the value 0.
The numbers in [] are array keys. So [1] is the second element of a numerically indexed array, (which starts with [0]), and the value of the second element ([1]) is 0.
PHP uses => as an operator to relate array keys/indices to their values.
So an overall explanation of this structure:
Array (
[0] => Array ( [0] => 1 [1] => 0 )
[1] => Array ( [0] => 2 )
[2] => Array ( [0] => 3 )
[3] => Array ( [0] => 4 )
)
The outer array is a numerically indexed array, and each of its elements is a sub-array. The first of them ([0]) is an array containing 2 elements, while the rest of them ([1] through [3]) are arrays containing only one single element.
That two-dimensional array is actually a one-dimensional array of arrays, which is why you're getting the nesting. The [x] => y bit simply means that index x of the array has the value y.
Now your output in this case doesn't actually match your code, since
$qid[0][0]=1;
$qid[1][0]=2;
$qid[2][0]=3;
$qid[3][0]=4;
print_r($qid);
produces:
Array (
[0] => Array ( [0] => 1 )
[1] => Array ( [0] => 2 )
[2] => Array ( [0] => 3 )
[3] => Array ( [0] => 4 )
)
If you wanted to get:
Array (
[0] => Array ( [0] => 1 [1] => 0 )
[1] => Array ( [0] => 2 )
[2] => Array ( [0] => 3 )
[3] => Array ( [0] => 4 )
)
(with the first array having two elements), you'd actually need:
$qid[0][0]=1;
$qid[0][1]=0;
$qid[1][0]=2;
$qid[2][0]=3;
$qid[3][0]=4;
print_r($qid);
You probably added a second item to $qid[0] somewhere ($qid[0][1] = 0). This code
$qid[0][0]=1;
$qid[1][0]=2;
$qid[2][0]=3;
$qid[3][0]=4;
outputs the the correct values for me (without [1] => 0:
Array ( [0] => Array ( [0] => 1 ) [1] => Array ( [0] => 2 ) [2] => Array ( [0] => 3 ) [3] => Array ( [0] => 4 ) )
It means that your index 0 in the original Array contains another Array of 2 items.
Specifically [1] => 0 means that the 2nd item of the "child" Array contains the number 0.
[1] => 0
in this simple way we can say that 1 is your array key and 0 is value for the 1 key
0 is store at the 1 key of the array
thanks
Simply put, you have a numerically indexed multidimensional array. http://php.net/manual/en/language.types.array.php should have all the information you need to read up on this.
As to why you have the [1] => 0, you'll need to look a little deeper into your code to see where it gets assigned.
I got the following result after printing out the array using print_r:
Array
(
[0] => Array
(
[0] => 1
)
[1] => Array
(
[0] => 2
)
[2] => Array
(
[0] => 3
)
[3] => Array
(
[0] => 4
)
)
I guess, you might have set a value for $gid[0][1] somewhere in your code.
