Merge 2 nested arrays in one with multiple values
(2 answers)
Closed 5 years ago.
how do i merge sub array into main array.
Array
(
[0] => Array
(
[FirmId] => 1
[PartyName] => abc medicals
[PartyCode] => P001
[SalesmanName] =>
)
[1] => Array
(
[FirmId] => 2
[PartyName] => xyz medicals
[PartyCode] => P001
[SalesmanName] =>
)
)
Array
(
[0] => Array
(
[SalesmanName] => abc
)
[1] => Array
(
[SalesmanName] => xyz
)
)
Output should be :
Array
(
[0] => Array
(
[FirmId] => 1
[PartyName] => abc medicals
[PartyCode] => P001
[SalesmanName] => abc
)
[1] => Array
(
[FirmId] => 2
[PartyName] => xyz medicals
[PartyCode] => P001
[SalesmanName] => xyz
)
)
I tried array_merge($arr1,$arr2); but output was not as expected.
Merge 2 nested arrays in one with multiple values
This solution is too expensive, actually my first array has 30 columns but i mentioned only 4 to simplify my question.
Actually second array is a sliced part of main array need to merge it.
http://php.net/manual/en/function.array-merge-recursive.php
you want to use array_merge_recursive()

Without any results :(

This is a multidimensional array, -> is used to access elements of object.
$myarray['Althetic'][1]['category_name'];

I need to explode stdentid array in comma separated value.currently the studentid array is in multidimensional array i need all the value should be in comma separated
The result should be for studentid array is
[studentid] => 36399,96500,96503,96509,96512 and so on..
Array
(
[started] => 1
[studentid] => Array
(
[1] => Array
(
[0] => 36399
)
[2] => Array
(
[0] => 96500
[1] => 96503
[2] => 96506
[3] => 96509
[4] => 96512
[5] => 96515
)
[3] => Array
(
[0] => 96501
[1] => 96504
[2] => 96507
[3] => 96510
[4] => 96513
)
[4] => Array
(
[0] => 96502
[1] => 96505
[2] => 96508
[3] => 96511
[4] => 96514
)
)
[name] => Test
[name_or_email] =>
[submitbtn] => 1
)
assuming your variable is $studentsResult (which contains the whole array you have posted)
in that case:
foreach($studentsResult['studentid'] as $studentId => $studentValues){
$tempStudents[$studentId] = join(',',$studentValues);
}
and then $tempStudents is what you're probably looking for\
If, however all those IDs needs to be under that ONE student, then you haven't said where is the ID, but you can follow the answer on flattening the array in one of the comments or do:
$tempStudents = [];
foreach($studentsResult['studentid'] as $someId => $studentValues){
$tempStudents = array_merge($tempStudents,$studentValues);
}
echo join(',',$tempStudents);
I want to replace the contents of array key [menu_order] with my new array part, whilst keeping the entire array together. Which way would be to replace that key?
Original complete array
variable - $full_array
Array
(
[menu_order] => Array
(
[0] => Array
(
[row_position] => 1
[row_identifier] => home
[original_row_position] => 1
[button_styling] => off
[tab] => self
)
[1] => Array
(
[row_position] => 2
[row_identifier] => benefits
[original_row_position] => 2
[button_styling] => off
[tab] => self
)
)
[policy] => Array
(
[override_privacy] => no
[privacy_override_textarea] =>
)
)
[menu_order] new data
variable - $menu_order_array_part
Array
(
[0] => Array
(
[row_position] => 1
[row_identifier] => home
[original_row_position] => 1
[button_styling] => off
)
[1] => Array
(
[row_position] => 2
[row_identifier] => benefits
[original_row_position] => 2
[button_styling] => off
)
)
I can't get the syntax correct for editing the original array whilst replacing a multidimensional array
Thanks,

You can use the key.
$full_array['menu_order'] = $menu_order_array_part;
Given this array:
Array
(
[0] => Array
(
[title] => this is the newest post
[ssm_featured_post_id] => 70
)
[1] => Array
(
[title] => sdfsfsdf
[ssm_featured_post_id] => 63
)
[2] => Array
(
[title] => test
[ssm_featured_post_id] => 49
)
[3] => Array
(
[title] => Hello world!
[ssm_featured_post_id] => 1
)
)
The ssm_featured_post_id value corresponds to the value of the array items in the second array.
I want to order the first array items in the same order as the items in the second array
Array
(
[1] => 63
[0] => 70
[3] => 1
[2] => 49
)
so the result after sorting would be
Array
(
[0] => Array
(
[title] => sdfsfsdf
[ssm_featured_post_id] => 63
)
[1] => Array
(
[title] => this is the newest post
[ssm_featured_post_id] => 70
)
[2] => Array
(
[title] => Hello world!
[ssm_featured_post_id] => 1
)
[3] => Array
(
[title] => test
[ssm_featured_post_id] => 49
)
)
The simpler way would be to use usort and write a function that uses the second table to compare two values from first table.
You may want to check out array_multisort, particularly the third example given. The idea is that you create arrays based on the "columns" of the multidimensional array, then sort them simultaneously, and put the result back in the original array.

i have an question about the behavior of using multi-level arrays, i want to use this function
$pages = $this->pdf_resolve_object($this->c, $this->root[1][1]['/Pages']);
and $this->root[1][1]['/Pages'] which i believe is used to check the array for these keys and if it exists then use as variable for pdf_resolve_object
so my question is 2-fold, one is does $this->root[1][1]['/Pages'] check the array and goes through the keys? if not what is its behavior? and 2 when it checks the array does it go through just the top 4 keys or all of the sub-keys?
If someone can help or link me to some learning material that would be much appreciated, thank you!
1) It does not check for the presence of the array keys -- rather it assumes that those keys already exist and passes the value into the function. If any of the keys did not exist, PHP would issue an E_NOTICE to the effect of Notice: Undefined index: that the key was not found. To check for them would require a call to isset() or array_key_exists() like:
if (isset($this->root[1][1]['/Pages'])) {
$pages = $this->pdf_resolve_object($this->c, $this->root[1][1]['/Pages']);
}
2) There is no need for it to iterate through to find the keys. Knowing the array keys already means they can be accessed directly without iteration. In memory, PHP has stored the array keys and the memory locations of the values they point to. Therefore, with the key alone, PHP can return the value without needing to traverse the array.
There is a lot of good information in the PHP manaul on Arrays
