There are two arrays

First array

array 0 => array (size=4) 'bonus' => string '5.625' (length=5) 'date' => string '2016-01' (length=7) 'year' => string '2016' (length=4) 'month' => string '1' (length=1) 1 => array (size=4) 'bonus' => string '2.5' (length=3) 'date' => string '2016-02' (length=7) 'year' => string '2016' (length=4) 'month' => string '2' (length=1) 2 => array (size=4) 'bonus' => string '2.5' (length=3) 'date' => string '2016-08' (length=7) 'year' => string '2016' (length=4) 'month' => string '8' (length=1) 3 => array (size=4) 'bonus' => string '10.625' (length=6) 'date' => string '2016-08' (length=7) 'year' => string '2016' (length=4) 'month' => null 4 => array (size=4) 'bonus' => string '22.125' (length=6) 'date' => string '2016-08' (length=7) 'year' => null 'month' => null

Second array

  array 0 => array (size=4) 'amount' => string '5' (length=1) 'date' => string '2016-07' (length=7) 'year' => string '2016' (length=4) 'month' => string '7' (length=1) 1 => array (size=4) 'amount' => string '6' (length=1) 'date' => string '2016-08' (length=7) 'year' => string '2016' (length=4) 'month' => string '8' (length=1) 2 => array (size=4) 'amount' => string '21' (length=2) 'date' => string '2016-08' (length=7) 'year' => string '2016' (length=4) 'month' => null 3 => array (size=4) 'amount' => string '21' (length=2) 'date' => string '2016-08' (length=7) 'year' => null 'month' => null

It is necessary to combine arrays, what would happen as follows

  array 0 => array (size=4) 'amount' => string '0' (length=1) 'bonus' => string '5.625' (length=5) 'date' => string '2016-01' (length=7) 'year' => string '2016' (length=4) 'month' => string '1' (length=1) 1 => array (size=4) 'amount' => string '0' (length=1) 'bonus' => string '2.5' (length=3) 'date' => string '2016-02' (length=7) 'year' => string '2016' (length=4) 'month' => string '2' (length=1) 2 => array (size=4) 'amount' => string '5' (length=1) 'bonus' => string '0' (length=3) 'date' => string '2016-07' (length=7) 'year' => string '2016' (length=4) 'month' => string '7' (length=1) 3 => array (size=4) 'amount' => string '6' (length=1) 'bonus' => string '2.5' (length=3) 'date' => string '2016-08' (length=7) 'year' => string '2016' (length=4) 'month' => string '8' (length=1) 4 => array (size=4) 'amount' => string '21' (length=1) 'bonus' => string '10.625' (length=6) 'date' => string '2016-08' (length=7) 'year' => string '2016' (length=4) 'month' => null 5 => array (size=4) 'amount' => string '21' (length=1) 'bonus' => string '22.125' (length=6) 'date' => string '2016-08' (length=7) 'year' => null 'month' => null

Array sizes are constantly different. I have already broken my head, I can’t understand how to unite them in this way.

if you need to merge both arrays into one you need to use the php function array_merge Here is the documentation - array_merge

  • array_merge doesn't fit, it doesn't merge properly - jemxx
  • @jemxx what exactly is wrong? - user193361
  • array_replace_recursive probably - Ninazu

You need the array_map function. In the callback function, merge both nested arrays into one. Read more here: http://php.net/manual/ru/function.array-map.php
