[RESOLVED] very simpe question - merging arrays

[jennyp]

I have two arrays. In both cases, each element is a string divided by a comma, like:

$FirstArray [0] == 'apple,pear'
$FirstArray [1] == 'banana,melon'

$SecondArray [0] == 'chair,table'
$SecondArray [1] == 'sofa,bench'

[etc]

How do I merge all this so that I have a single array with the comma-separated string values, like this:

$NewArray[0] == 'apple'
$NewArray[1] == 'pear'
$NewArray[2] == 'banana'
$NewArray[3] == 'melon'
$NewArray[4] == 'chair'
$NewArray[5] == 'table'
$NewArray[6] == 'sofa'
$NewArray[7] == 'bench'

[etc]

<?php
function split_array($arr)
{
   if(!is_array($arr))
   {
      user_error("split_arr(): arg not an array", E_USER_WARNING);
      return(FALSE);
   }
   $outArray = array();
   foreach($arr as $text)
   {
      foreach(explode(',', $text) as $item)
      {
         $outArray[] = $item;
      } 
   }
   return($outArray);
}

$FirstArray [0] = 'apple,pear';
$FirstArray [1] = 'banana,melon';

$SecondArray [0] = 'chair,table';
$SecondArray [1] = 'sofa,bench';

$NewArray = array_merge(split_array($FirstArray), split_array($SecondArray));

print_r($NewArray);
?>

Hmm... it'll take a couple steps:

<?php

$example = array('apple,pear','banana,melon');
$example2 = array('chair,table','sofa,bench');

// first we'll make a temporary array of each individual item:
$temp1 = array();
$temp2 = array();

foreach($example AS $item)
{
  list($n,$k) = explode(",", $item);
  $temp1[] = $n;
  $temp1[] = $k;
}

foreach($example2 AS $item)
{
  list($n, $k) = explode(",", $item);

  $temp2[] = $n;
  $temp2[] = $k;
}
// Debugging:
echo '<pre>';
print_r($temp1);
print_r($temp2);
echo '</pre><hr>';

// Now we merge them ;)
$newArray = array_merge($temp1, $temp2);

// Double check it:
echo '<pre>';
print_r($newArray);
echo '</pre>';

?>

That gives you this output:

Array
(
    [0] => apple
    [1] => pear
    [2] => banana
    [3] => melon
)
Array
(
    [0] => chair
    [1] => table
    [2] => sofa
    [3] => bench
)
--------------------------------------
Array
(
    [0] => apple
    [1] => pear
    [2] => banana
    [3] => melon
    [4] => chair
    [5] => table
    [6] => sofa
    [7] => bench
)

Edit
Damn it... just a few seconds too slow.

Thank you!!! I have a similar situation with just one array, where the values are of a similar sort:

$array [0] == 'apple,pear'
$array [1] == 'banana,melon'
$array [2] == 'chair,table'
$array [3] == 'sofa,bench'
[etc]

How would I take each string and put it into an array element, like:

$array [0] == 'apple'
$array [1] == 'pear'
$array [2] == 'banana'
$array [3] == 'melon'
[etc]?

Many thanks for untangling this for me

You can just use the function in my other reply once without doing the array_merge():

$newArray = split_array($oldArray);

Sorry should have seen that - thank you!!!!!
