Counting rows/records in a multidimensional array - php

Question

I have a set of nested arrays.
[data] is the top level array.
The lower level arrays are all identified by incremental numbers, dynamically assigned...essentially each sub-array identifies a row/record of information.
How would I extract the count of the sub-arrays? I need to be able to do this to post this data into a DB.
The number of sub-arrays is dynamic, and can change depending on what data I am parsing through.
[data] => Array
(
[0] => Array
(
[id] => 3475
[name] => Player1
[score] => 11870
[rank] => 213
[total_cities] => 2
[crown] => None
[alliance_id] => 134
[title] => Earl
[fame_total] => 509875
[fame_rank] => 381
[defeated_total] => 3436
[defeated_rank] => 376
[plunder_total] => 1388754
[plunder_rank] => 245
)
[1] => Array
(
[id] => 3523
[name] => Player2
[score] => 1978
[rank] => 281
[total_cities] => 1
[crown] => None
[alliance_id] => 134
[title] => Baron
[fame_total] => 0
[fame_rank] => 448
[defeated_total] => 0
[defeated_rank] => 448
[plunder_total] => 0
[plunder_rank] => 436
)
[2] => Array
(
[id] => 73
[name] => Player3
[score] => 1308
[rank] => 304
[total_cities] => 1
[crown] => None
[alliance_id] => 134
[title] => Marquess
[fame_total] => 5604153
[fame_rank] => 237
[defeated_total] => 37270
[defeated_rank] => 229
[plunder_total] => 68130
[plunder_rank] => 335
)

Answer 1

I used a combination of the methods highlighted by Marc B and Thanos to get my desired result
This is the code I used:
$count = 0;
foreach($data as $data=>$inner_array){
$count = $count+1;
}
echo $count;
I ran it with a test data set with 143 unique rows, and I got that echo back, so life is good.
Thanks guys.

Simplest method:
$count = 0;
foreach($mainarray as $subarray)
$count += count($subarray);
}

Answer 3

Let's assume $data is your main array:
This one prints the name of each inner array (0, 1, 2... for your example) and then counts each sub-array items:
echo "Number of sub-arrays: ".count($online_time); //optional
foreach($data as $inner_array=>$data_of_inner_array) {
echo $inner_array;
echo " --- ".count($data_of_inner_array);
echo "<br/>";
}
i assume output will be
Number of sub-arrays: 3
0 --- 14
1 --- 14
2 --- 14
