How to merge 10 array keys and values , and update the particular array?

Question

We are looking a function that can merge the array keys and values and update it particularly.

$array = array('testing1','testing2','testing3','testing4','testing5','testing6','testing7','testing8','testing9','testing10','testing11','testing12','testing13','testing14');

we just want to merge 10 values with 'space' like this.

$finalarray = array('testing1 testing2 testing3 testing4 testing5 testing6 testing7 testing8 testing9 testing10', 'testing11 testing12 testing13 testing14'); 

Is there any function that do same thing in PHP ?

Answer 1

you can use array_chunk with array_map

    $array = array('testing1','testing2','testing3','testing4','testing5','testing6','testing7','testing8','testing9','testing10','testing11','testing12','testing13','testing14');
    $final = array_chunk($array,10);    
    $final = array_map(function ($n){return implode(" ", $n);}, $final);

Output

array
  0 => string 'testing1 testing2 testing3 testing4 testing5 testing6 testing7 testing8 testing9 testing10' (length=90)
  1 => string 'testing11 testing12 testing13 testing14' (length=39)
