Combining arrays

[blinks58]

I have 2 arrays :

 

$array1=

Array (
 [0] => Array (
  [id] => 411
  [pa] => book
  [rm] => 32)
 [1] => Array (
  [id] => 974
  [pa] => journal
  [rm] => 76)
 [2] => Array (
  [id] => 3041
  [pa] => book
  [rm] => 85 )
 [3] => Array (
  [id] => 3852
  [pa] => paper
  [rm] => 60 )
  )
  
$array2=

Array (
 [0] => Array (
  [AU] => 3041
  [NL] => 1490240
  [CID] => 52
 [1] => Array (
  [AU] => 974
  [NL] => 1490241
  [CID] => 76
 [2] => Array (
  [AU] => 390
  [NL] => 1491023
  [CID] => 56 )
  )

 

where the id field in $array1 should match the AU field in $array2 (although there won't always be a match in $array2).

 

I want to combine the 2 arrays into 1, where all the rows in $array1 are retained, along with any fields in $array2 that are not in $array1. Like this -

 

Array (
 [0] => Array (
  [id] => 411
  [pa] => book
  [rm] => 32)
  [NL] => 
  [CID] =>  )
 [1] => Array (
  [id] => 974
  [pa] => journal
  [rm] => 76)
  [NL] => 1490241
  [CID] => 76 )  
 [2] => Array (
  [id] => 3041
  [pa] => book
  [rm] => 85
  [NL] => 1490240
  [CID] => 52 )  
 [3] => Array (
  [id] => 3852
  [pa] => paper
  [rm] => 60
  [NL] => 
  [CID] =>  )
  )   

 

I'd appreciate some assistance about how best to do this. I've been using various combinations of in_array so far, with no luck.

Try using "array_merge" and "array_merge_recursive" php functions

Thanks for your help, pbs. I'm not having much luck, though, as these two functions just append one array to the bottom of the other, without doing the combining bit.

Try using a for loop.

 

<?php

$array1 = array(...);
$array2 = array(...);

for($i = 0; $i < 4; $i++)
{
array_push($array1[i], $array2[i]);
return $array1;
}

...

?>

Thanks heaps, Irate. With your array_push suggestion, I was finally able to figure it out.

Mmm, you're welcome.
