PHP array's, how to access keys and values - php

Question

Trying to learn multidimensional arrays but seem to constantly struggle with accessing them. I still have not got grasps of how you access them using index, keys, values.
How do I get to the actual word "Title" and it's value?
Here I have one I was playing with.
$shop = array( array( "Title" => "rose",
"Price" => 1.25,
"Number" => 15
),
array( "Title" => "daisy",
"Price" => 0.75,
"Number" => 25,
),
array( "Title" => "orchid",
"Price" => 1.15,
"Number" => 7
)
);
Which prints a structure such as this:
Array
(
[0] => Array
(
[Title] => rose
[Price] => 1.25
[Number] => 15
)
[1] => Array
(
[Title] => daisy
[Price] => 0.75
[Number] => 25
)
[2] => Array
(
[Title] => orchid
[Price] => 1.15
[Number] => 7
)
)
echo $shop[0][0][0]; //I Expect "rose" but I get "Undefined offset: 0"
echo $shop['Price']; //I expect 1.25 but I get "Undefined index: Price"
foreach($shop as $key=>$value)
{
echo $key; //I expect the key values "Title/Price/Number" instead I get Index numbers 0 1 2
echo $value; //I expect all values of keys e.g. "rose",1.25,15/"daisy",0.75,25/"orchid",1.15,7 Instead I get Array to string conversion error
}
What I am trying to do, is take all the title and value from the shop array, and put it into a new array called $x = array(); and then take a car key/value from a different array and combine them together.
so the new array ends up looking like this:
Array
(
[0] => Array
(
[Title] => rose //from $shop array
[Car] => Mercedez //from $car array
)
[1] => Array
(
[Title] => daisy //from $shop array
[Car] => Ford //from $car array
)
[2] => Array
(
[Title] => orchid //from $shop array
[Car] => Bentley //from $car array
)
)
Also is there a way to access the actual name of the key "title" and not a index number?

Answer 1

You have an array of arrays, therefore you'll need two loops.
foreach ($shop as $item) {
foreach ($item as $key => $value) {
echo $key;
echo $value;
}
}

Answer 2

Try this -
$newarray = array();
foreach($shop as $key=>$value) {
$newarray[$key]['Title'] = $value['Title'];
$newarray[$key]['Number'] = $value['Number'];
}
echo "<pre>";print_r($newarray);
Here, $newarray will give you output like this.
Array
(
[0] => Array
(
[Title] => rose
[Number] => 15
)
[1] => Array
(
[Title] => daisy
[Number] => 25
)
[2] => Array
(
[Title] => orchid
[Number] => 7
)
)

Answer 3

You could access by $shop[0]['Title']
0 means the first item in array and this item is also an array, which contains string keys so 'title' as second level.
To iterate it use:
//Syntax array as key => value (value is in this case also an array)
foreach($shop as $iterator_level1 => $shop_set){
//so you can access the 2. level by string key.
echo $shop_set['title'];
}
Hope this is helpful.
