php - Separating array rows into other arrays based on key name -

i have array this

$rows = array(     array(         'fruit.name' => 'apple',         'fruit.colour' => 'red',         'fruit.weight' => '0.1',         'vegetable.name' => 'carrot',         'vegetable.colour' => 'orange',         'vegetable.weight' => '0.05'     ),     array(         'fruit.name' => 'banana',         'fruit.colour' => 'yellow',         'fruit.weight' => '0.7',         'vegetable.name' => 'potato',         'vegetable.colour' => 'brown',         'vegetable.weight' => '0.6'     ) ); 

and want able sort array 2 other arrays called 'fruits' , 'vegetables' based on first part of key name decimal point. array should have 2 rows in each of fruits , vegetable arrays.

i have code doesn't work , can't see i'm doing wrong.

$fruits = array(); $vegetables = array();  foreach($rows $row) {     foreach($row $key => $value)      {         if('fruit' == substr($key, 0, strpos($key, '.')))         {             $fruits[$key] = $row;         }         else         {             $vegetables[$key] = $row;         }      } }  echo "<pre>"; var_dump($fruits); echo "</pre>";  

when var_dump this

array(3) {   ["fruit.name"]=>   array(6) {     ["fruit.name"]=>     string(6) "banana"     ["fruit.colour"]=>     string(6) "yellow"     ["fruit.weight"]=>     string(3) "0.7"     ["vegetable.name"]=>     string(6) "potato"     ["vegetable.colour"]=>     string(5) "brown"     ["vegetable.weight"]=>     string(3) "0.6"   }   ["fruit.colour"]=>   array(6) {     ["fruit.name"]=>     string(6) "banana"     ["fruit.colour"]=>     string(6) "yellow"     ["fruit.weight"]=>     string(3) "0.7"     ["vegetable.name"]=>     string(6) "potato"     ["vegetable.colour"]=>     string(5) "brown"     ["vegetable.weight"]=>     string(3) "0.6"   }   ["fruit.weight"]=>   array(6) {     ["fruit.name"]=>     string(6) "banana"     ["fruit.colour"]=>     string(6) "yellow"     ["fruit.weight"]=>     string(3) "0.7"     ["vegetable.name"]=>     string(6) "potato"     ["vegetable.colour"]=>     string(5) "brown"     ["vegetable.weight"]=>     string(3) "0.6"   } } 

any please getting separate array 2 arrays each containing either fruits or vegetables.

this seems work:

$rows = array(         array(             'fruit.name' => 'apple',             'fruit.colour' => 'red',             'fruit.weight' => '0.1',             'vegetable.name' => 'carrot',             'vegetable.colour' => 'orange',             'vegetable.weight' => '0.05'         ),         array(             'fruit.name' => 'banana',             'fruit.colour' => 'yellow',             'fruit.weight' => '0.7',             'vegetable.name' => 'potato',             'vegetable.colour' => 'brown',             'vegetable.weight' => '0.6'         )     );       $fruits = $vegs = array();     foreach ($rows $arrays) {          $fruit = array();         $veg = array();         foreach ($arrays $key => $val) {              $index = substr($key, strpos($key, ".") + 1);                 if('fruit' == substr($key, 0, strpos($key, '.'))){                  $fruit[$index] = $val;             } else {                 $veg[$index] = $val;             }         }          $fruits[] = $fruit;         $vegs[] = $veg;     }      var_dump($fruits, $vegs); 

(please overlook fact i've called 1 of vars $vegs)

hope helps!
