multidimensional array using foreach - php

Question

I'm writing a code for looping out data from an multi dimensional array.
While looping I got confused while getting the details from an array. I have tried several ways for getting but in vain.
Now what I want is to get the values from the key 4 provided in the array.
Array
(
[match1] => Array
(
[4] => Array
(
[0] => Array
(
[0] => Sanjay
[1] => Delhi
[2] => 23
)
[1] => Array
(
[0] => Ram
[1] => Mumbai
[2] => 26
)
)
[5] => Array
(
[0] => Array
(
[0] => Sanjay
[1] => Delhi
[2] => 23
)
[1] => Array
(
[0] => Ram
[1] => Mumbai
[2] => 26
)
)
)
)
Thanks

Answer 1

In order to access the multi dimensional array you need to access via foreach() or directly by using the keys that you have in the print_r() function.
Hence as per your Example you can directly access the variable the you need using the
first array variable along with the key that the first array has.
Consider this array and you need to fetch the first value you can process like this.
print_r($var); resulting in this
Array
(
[match1] => Array
(
[4] => Array
(
[0] => Array
(
[0] => Sanjay
[1] => Delhi
[2] => 23
)
[1] => Array
(
[0] => Ram
[1] => Mumbai
[2] => 26
)
)
)
)
You can retrieve the variable in two methods as follows
Method One:
As the variable that contains the array is $var hence you need to access like this.
In order to fetch the value that the key has you can have $var['match1'][4] and you can apply foreach over to the variable and get the value that it has.
foreach($var['match1'][4] as $inner_value)
{
// Do what ever stuff you need
}
Method Two:
Getting key value 0 - 0 in the array that it has you can code as - $var['match1'][4][0]
Getting key value 1 - 1 in the array that it has you can code as - $var['match1'][4][1]
You can get as much value inside the array as you can with the help of the above two points
Output for both it will be the same as follows
Sanjay Delhi 23
Ram Mumbai 26

Answer 2

It's really very simple. Let's assume the name of your main array is $mainarray. So here is how you can get the array of key 4.
$key4array=$mainarray['match1'][4];
foreach($key4array as $arrayele) {
echo $arrayele[0]." ".$arrayele[1]." ".$arrayele[2]."<br>";
}
Output will be,
Sanjay Delhi 23
Ram Mumbai 26
Access the first level array by match1 key and then 4 as index to get the second level array.
