I have two type of array.
First type
$arr = [1,2,3];
Second type
$arr = [[1,2,3],[4,5,6],[7,8,9]];
How to check that my array is single or multi array.
I am using below code which is always giving me as Multi Array
if(is_array($arr)){
echo "Multi Array";
} else{
echo "SingleArray";
}
You are asking if you can check for your array being multi-dimensional, to which end, I came up with a function not so long ago;
<?php
function is_multidimensional(array $array)
{
foreach ($array as $part)
{
if (is_array($part)) return true;
}
return false;
}
$is_md_array = is_multidimensional($myarray); // True if it is, false if not
There is nothing to say that this can't be made fully recursive to check further down the array too, but this is a good start if you need this more often than once
This attempt is not as good as Sam Swift's answer as it does not stop on the 1st array encountered and it can be slow with large arrays because of in_array().
But here it is:
// This will contain an array of boolean (is the item an array or not)
$are_arrays = array_map( function ($a) {
return is_array($a);
}, $arr );
// This will return if true is found in our previous array
$is_multi = in_array(true, $are_arrays);
// Output debug
var_dump($is_multi);
It can fit into one single line for a "quick check":
$is_multi = in_array(true, array_map(function ($a) { return is_array($a); }, $arr));
if(is_array($arr) and is_array($arr[0]))
