Split large array into several arrays based on array field value

Question

I have an array, and its large. very large. Its for a real estate company. I would like to split the array into sections based on the number of bedrooms each home has. So ideally all the entries (like the one below) that had 0 bedrooms would be set into one array, and with 1, into another. etc...

Is this possible?

object(SimpleXMLElement)#124 (1) {
  ["unit"]=>
  array(40) {
    [0]=>
    object(SimpleXMLElement)#246 (1) {
      ["@attributes"]=>          array(28) {
        ["mlsnumber"]=>            string(8) "A1837040"
        ["type"]=>            string(0) ""
        ["unit"]=>            string(3) "607"
        ["maintenancefee"]=>            string(4) "1609"
        ["price"]=>            string(6) "890000"
        ["salesprice"]=>            string(0) ""
        ["bath"]=>            string(1) "1"
        ["hbath"]=>            string(1) "0"
        ["beds"]=>            string(1) "0"
        ["sqft"]=>            string(3) "747"
        ["sqftm"]=>            string(5) "69.40"
        ["pricesqft"]=>            string(8) "1,191.43"
        ["lat"]=>            string(16) "25.7683201213024"
        ["lng"]=>            string(16) "-80.132474899292"
        ["pricemeters"]=>            string(9) "12,824.21"
        ["pricechange"]=>            string(5) "-6.32"
        ["dom"]=>            string(3) "181"
        ["reo"]=>            string(1) "N"
        ["shortsale"]=>            string(1) "N"
        ["dropprice"]=>            string(0) ""
        ["pets"]=>            string(3) "Yes"
        ["furnished"]=>            string(1) "U"
        ["FloorLevel"]=>            string(1) "6"
      }
    }

Is all the arrays inside unit?

Loop through the array and push the current array into a new array whereas the index of the new array is the number of bedrooms of the current array. You'll need to convert your object into an array first, then something along the lines of this:

  foreach($all_units as $unit){
    if(!isset($new[$unit['beds']])){
          $new[$unit['beds']] = array();
    }
    array_push($new[$unit['beds']],$unit);
  }
  print_r($new);

I have 6 sets of bed counts. 1,2,3,4,5,7. This code looks like it will only push out array for zero beds.

Rid Iculous Over a year ago

why? the !isset merely avoids the warning. If $unit[beds] contains the number of bedrooms You end up with a multi-dimensional array $new that is indexed by the number of bedrooms, ie $unit[2] contains arrays with 2 bedrooms.

I did try it, it returns Parse error: syntax error, unexpected ',', expecting ']'

Suppose $arr holds your result, Try

$result = array();
foreach($arr['unit'] as $prop){
  $result[$prop["beds"]][] = $prop;
}
