divide an array into 4 subarrays

Here is an example array I want to split:

```(1428,217,1428)
```

How do I split it in 2 array like this?

```(1428,1428)
(217)
```

I have tried following way but it's only return 1428 array.

```\$counts = array_count_values(\$array);
\$filtered = array_filter(\$array, function (\$value) use (\$counts) {
return \$counts[\$value] > 1;

});
```

One way to solve this for your example data is to sort the array and use array_shift to get the first element of the array and store that in an array.

```\$a = [1428,217,1428];
sort(\$a);
\$b = [array_shift(\$a)];

print_r(\$a);
print_r(\$b);
```

Result

```Array
(
[0] => 1428
[1] => 1428
)
Array
(
[0] => 217
)
```

Split an array into two equal Sum subarrays, Given an array of integers greater than zero, find if it is possible to split it in two subarrays (without A Simple solution is to run two loop to split array and check it is possible to split array into two parts such Minimum value to add to arr[i] so that an array can be split at index i with equal sum · Split the Based on 39 vote(​s). Creating arrays by using split method in a string We have seen how to create string using elements of an array. Now we will see how to create an array from a string by using some delimiter. For this we will use split() method which works on a string and create array out of it. This is one of the method used to create an array.

You can try this.

```\$array = array(1428,217,1428);
\$array1 = array_slice(\$array, 0, 2);
\$array2 = array_slice(\$array, 2, 3);
print_r(\$array1);
print_r(\$array2);
```

And the output will like this:-

```Array
(
[0] => 1428
[1] => 217
)
Array
(
[0] => 1428
)
```

Convert one array into two arrays along with some actions , I have an array like as input fields and that needs to convert in two arrays like The split() method splits a String object into an array of strings by numero intero (int) utilizzando la base specificata 'radix' (base intesa come  In this post, we will see how to split array into two parts in Java. If the array contains an odd number of items, the extra item should be part of the first array. 1. Naive. Naive solution would to create two new arrays and assign elements from first half of the source array to the first array and elements from second half of the source array to the second array.

In your case it will only return 1428 since `array_count_values` returns an array with values as keys and their frequency as array value therefore \$counts will be equal to `array('1428' => 2, '217' => 1);`

If I understood your question well you should do something like this:

```\$array1 = [1428, 217, 1428];
\$result = [];
foreach(\$array1 as \$value){
\$result[\$value][] = \$value;
}
```

This will not create an array for each different value but will create a new element for each unique value in `\$result`. The final value of `\$result` will be `array('1428' => [1428, 1428], '217' => [217])` . Which can be easily manipulated as if they were 2 different arrays.

Let me know if this works for you, if not I will try to update my answer according to your specification.

Split Array into Two Parts in Java, 1. Naive. Naive solution would to create two new arrays and assign elements from first half of the source array to the first array and elements from second half  Split an array into two equal Sum subarrays Split an array into two equal Sum subarrays Given an array of integers greater than zero, find if it is possible to split it in two subarrays (without reordering the elements), such that the sum of the two subarrays is the same. Print the two subarrays.

Array methods, To make things easier, in this chapter they are split into groups. to 0 : let arr = [ "​I" , "study" , "JavaScript" ] ; // from index 2 // delete 0 // then insert "complex" and They are used to calculate a single value based on the array. Now I want to split a into two parts, one is all numbers <5 and the other is all >=5: [array([1,3,2,4]), array([5,7,6,8])] Certainly I can traverse a and create two new array.

Statistical Computing in C++ and R, The algorithm returns the node that has the desired key value or NULL if no To illustrate the mergesort method, let us again consider sorting the integer To begin, divide this array into the subarrays (15,1,18,28,27) and (19,49,38,6,2,40). second array which we split into two more three component arrays (19,49,38) and  I have a PHP array that I am trying to split into 2 different arrays. I am trying to pull out any values that contain the word "hidden". So one array would contain all the values that do not contain the word "hidden". The other array would contain all the values that do contain the word "hidden". I just can't figure out how to do it though.

Documentation: 9.1: Array Functions and Operators, Table 9-41 shows the operators available for array types. overlap (have elements in common), ARRAY[1,4,3] && ARRAY[2,1], t array_fill (anyelement, int[], [, int[]]), anyarray, returns an array initialized with supplied value and dimensions, array. Otherwise the input string is split at each occurrence of the delimiter string. However, in case the original array exists long enough, you might not even need to do that. You could just 'split' the array into two new arrays by using pointers into the original array: int array[6] = {1,2,3,4,5,6} int *firstHalf = array; int *secondHalf = array + 3; share.

• what exactly do you want to achieve? Do you want to separate duplicate numbers in a different array? It will only return 1428 since `array_count_values` returns an array with values as keys and their frequency as value therefore \$counts will be equal to `array('1428' => 2, '217' => 1);`. In your filter you are only returning the value if its frequency is bigger than 1, which only 1428 has a frequency bigger than 1 hence returning 1428 only. You need to explain what you want to achieve in the end.
