Push an associate array into another array - php

Question

I am trying to do a custom WP_query loop and put the results into an array of associate arrays.. It is not working too well.. I realize the array_push overwrites any arrays that have the same indexes so I have the index increment +1 in the loop so they are not identical..however it still is not working.. My results show correct only on the first index (zero).. Here is my code:
<?php
$permlink='permalink';
$excerpt='exerpt';
$title='title';
$id='id';
$finalarray=array();
for ($i = 0; $i <= 10; $i++) {
$newitem = array(array(
'id'.$i =>$id.$i,
'title'.$i => $title.$i,
'excerpt'.$i => $excerpt.$i,
'permalink'.$i => $permlink.$i
));
array_push($finalarray, $newitem);
}
$count=0;
foreach($finalarray as $item){
echo $count.':'.'<br>';
echo $item[$count]['title'.$count];
echo $item[$count]['id'.$count];
echo $item[$count]['permalink'.$count];
$count++;
}
var_dump($finalarray);
?>
Any my results show :
0:
title0id0permalink01:
2:
3:
4:
5:
6:
7:
8:
9:
10:
array(11) { [0]=> array(1) { [0]=> array(4) { ["id0"]=> string(3) "id0" ["title0"]=> string(6) "title0" ["excerpt0"]=> string(7) "exerpt0" ["permalink0"]=> string(10) "permalink0" } } [1]=> array(1) { [0]=> array(4) { ["id1"]=> string(3) "id1" ["title1"]=> string(6) "title1" ["excerpt1"]=> string(7) "exerpt1" ["permalink1"]=> string(10) "permalink1" } } [2]=> array(1) { [0]=> array(4) { ["id2"]=> string(3) "id2" ["title2"]=> string(6) "title2" ["excerpt2"]=> string(7) "exerpt2" ["permalink2"]=> string(10) "permalink2" } } [3]=> array(1) { [0]=> array(4) { ["id3"]=> string(3) "id3" ["title3"]=> string(6) "title3" ["excerpt3"]=> string(7) "exerpt3" ["permalink3"]=> string(10) "permalink3" } } [4]=> array(1) { [0]=> array(4) { ["id4"]=> string(3) "id4" ["title4"]=> string(6) "title4" ["excerpt4"]=> string(7) "exerpt4" ["permalink4"]=> string(10) "permalink4" } } [5]=> array(1) { [0]=> array(4) { ["id5"]=> string(3) "id5" ["title5"]=> string(6) "title5" ["excerpt5"]=> string(7) "exerpt5" ["permalink5"]=> string(10) "permalink5" } } [6]=> array(1) { [0]=> array(4) { ["id6"]=> string(3) "id6" ["title6"]=> string(6) "title6" ["excerpt6"]=> string(7) "exerpt6" ["permalink6"]=> string(10) "permalink6" } } [7]=> array(1) { [0]=> array(4) { ["id7"]=> string(3) "id7" ["title7"]=> string(6) "title7" ["excerpt7"]=> string(7) "exerpt7" ["permalink7"]=> string(10) "permalink7" } } [8]=> array(1) { [0]=> array(4) { ["id8"]=> string(3) "id8" ["title8"]=> string(6) "title8" ["excerpt8"]=> string(7) "exerpt8" ["permalink8"]=> string(10) "permalink8" } } [9]=> array(1) { [0]=> array(4) { ["id9"]=> string(3) "id9" ["title9"]=> string(6) "title9" ["excerpt9"]=> string(7) "exerpt9" ["permalink9"]=> string(10) "permalink9" } } [10]=> array(1) { [0]=> array(4) { ["id10"]=> string(4) "id10" ["title10"]=> string(7) "title10" ["excerpt10"]=> string(8) "exerpt10" ["permalink10"]=> string(11) "permalink10" } } }
So it looks like the values are in the array, however, only the first index ( zero ) prints correctly.. any suggestions? Also, is there any way i can push an associate array and it not be over written so I dont have to increment the index?

Answer 1

There are a few problems here.
for ($i = 0; $i <= 10; $i++) {
$newitem = array(array(
'id'.$i =>$id.$i,
'title'.$i => $title.$i,
'excerpt'.$i => $excerpt.$i,
'permalink'.$i => $permlink.$i
));
array_push($finalarray, $newitem);
}
You are pushing an array, containing an array, containing 4 elements into $finalarray. There is no need for the outer array(). You can just do $newitem = array(...). array_push appends to end of the array, incrementing the index for you.
Second, in your foreach, your $count variable is not needed at all. When using foreach, $item is the element of the array. No need to look it up by the index.
If you want the index, however, foreach can give it to you.
foreach($finalarray as $count=>$item){
echo $count.':'.'<br>';
echo $item['title'.$count];
echo $item['id'.$count];
echo $item['permalink'.$count];
}
Your original code wasn't working because in each $item there was one array. That array had one item. In each element, the inner aray was always at index 0. Incrementing $count made it so only the 1st element worked, the others didn't because $item[1] didn't exist, it was always $item[0].

for ($i = 0; $i <= 10; $i++) {
$newitem = array(array(
'id'.$i =>$id.$i,
'title'.$i => $title.$i,
'excerpt'.$i => $excerpt.$i,
'permalink'.$i => $permlink.$i
));
$finalarray[] = $newitem;
unset($newitem);
}
Since you don't care about the key of the final array just add it on using $finalarray[]
