Checking if array is multidimensional or not?

How do I check whether an array is multidimensional or not in PHP?

Answer 1

Use count twice, one with single parameter, and one with recursive mode

if (count($myarray) == count($myarray, COUNT_RECURSIVE)) 
{
  echo 'MyArray is not multidimensional';
}
else
{
  echo 'MyArray is multidimensional';
}

count(array,mode)

• array —Required. Specifies the array or object to count.

• mode —Optional. Specifies the mode of the function. Possible values:

  • 0 – Default. Does not detect multidimensional arrays (arrays within arrays)
  • 1 – Detects multidimensional arrays

Note: This parameter was added in PHP 4.2
