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

Question

I have an array like 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 i want to be able to sort the array into 2 other arrays called 'fruits' and 'vegetables' based on the first part of the key name so up to the decimal point. With this array I should have 2 rows in each of the fruits and vegetable arrays.
I have this code but it doesn't work and I can't see what I'm doing wrong.
$fruits = array();
$vegetables = array();
foreach($rows as $row)
{
foreach($row as $key => $value)
{
if('fruit' == substr($key, 0, strpos($key, '.')))
{
$fruits[$key] = $row;
}
else
{
$vegetables[$key] = $row;
}
}
}
echo "<pre>"; var_dump($fruits); echo "</pre>";
When i do a var_dump i get 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 help please getting this to separate the array into 2 arrays each containing either fruits or vegetables.

Answer 1

This seems to 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 as $arrays) {
$fruit = array();
$veg = array();
foreach ($arrays as $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 the fact I've called one of the vars $vegs)
Hope this helps!

Answer 2

I didn't run the code, but it looks like you want:
$fruits[$key] = $value;
-AND-
$vegetables[$key] = $value;
