how to get value from associative array - php

Question

This is my array :
Array
(
[0] => Array
(
[0] => S No.
[1] => Contact Message
[2] => Name
[3] => Contact Number
[4] => Email ID
)
[1] => Array
(
[0] => 1
[1] => I am interested in your property. Please get in touch with me.
[2] => lopa <br/>(Individual)
[3] => 1234567890
[4] => loperea.ray#Gmail.com
)
[2] => Array
(
[0] => 2
[1] => This user is looking for 3 BHK Multistorey Apartment for Sale in Sohna, Gurgaon and has viewed your contact details.
[2] => shiva <br/>(Individual)
[3] => 2135467890
[4] => sauron82#yahoo.co.in
)
)
How can I retrieve all data element wise?

Answer 1

You can get information about arrays in PHP on the official PHP doc page
You can access arrays using square braces surrounding the key you like to select [key].
So $array[1] will give yoo:
Array
(
[0] => 1
[1] => I am interested in your property. Please get in touch with me.
[2] => lopa <br/>(Individual)
[3] => 1234567890
[4] => loperea.ray#Gmail.com
)
And $array[1][2] will give you:
lopa <br/>(Individual)
Or you can walkt through the elements of an array using loops like the foreach or the for loop.
// perfect for assoc arrays
foreach($array as $key => $element) {
var_dump($key, $element);
}
// alternative for arrays with seamless numeric keys
$elementsCount = count($array);
for($i = 0; $i < $elementsCount; ++$i) {
var_dump($array[$i]);
}

Answer 2

You have integer indexed elements in multidimensional array. To access single element from array, use array name and it's index $myArray[1]. To get inner element of that previous selected array, use second set of [index] - $myArray[1][5] and so on.
To dynamically get all elements from array, use nested foreach loop:
foreach ($myArray as $key => $values) {
foreach ($values as $innerKey => $value) {
echo $value;
// OR
echo $myArray[$key][$innerKey];
}
}

Answer 3

The solution is to use array_reduce:
$header = array_map(
function() { return []; },
array_flip( array_shift( $array ) )
); // headers
array_reduce( $array , function ($carry, $item) {
$i = 0;
foreach( $carry as $k => $v ) {
$carry[$k][] = $item[$i++];
}
return $carry;
}, $header );
First of all we get the header from the very first element of input array. Then we map-reduce the input.
That gives:
$array = [['A', 'B', 'C'], ['a1', 'b1', 'c1'], ['a2', 'b2', 'c2'], ['a3', 'b3', 'c3']];
/*
array(3) {
'A' =>
array(3) {
[0] =>
string(2) "a1"
[1] =>
string(2) "a2"
[2] =>
string(2) "a3"
}
'B' =>
array(3) {
[0] =>
string(2) "b1"
[1] =>
string(2) "b2"
[2] =>
string(2) "b3"
}
'C' =>
array(3) {
[0] =>
string(2) "c1"
[1] =>
string(2) "c2"
[2] =>
string(2) "c3"
}
}
*/

I think this is what you are looking for
$array = Array
(
0=> Array
(
0 => 'S No.',
1 => 'Contact Message',
2 => 'Name',
3 => 'Contact Number',
4 => 'Email ID'
),
1 => Array
(
0 => 1,
1 => 'I am interested in your property. Please get in touch with me.',
2 => 'lopa <br/>(Individual)',
3 => '1234567890',
4 => 'loperea.ray#Gmail.com',
),
2 => Array
(
0 => 2,
1 => 'This user is looking for 3 BHK Multistorey Apartment for Sale in Sohna, Gurgaon and has viewed your contact details.',
2 => 'shiva <br/>(Individual)',
3 => '2135467890',
4 => 'sauron82#yahoo.co.in',
)
);
$result_array = array();
array_shift($array);
reset($array);
foreach($array as $x=>$array2){
foreach($array2 as $i => $arr){
if($i == 1){
$result_array[$x]['Contact Message'] = $arr;
}elseif($i == 2){
$result_array[$x]['Name'] = $arr;
}elseif($i == 3){
$result_array[$x]['Contact Number'] =$arr;
}elseif($i == 4){
$result_array[$x]['Email ID'] = $arr;
}
}
}
print_r($result_array);
