You can create a function like this:

function countRes($arr) {
    return is_array(end($arr)) ? count($arr) : 1;
}

$arr1 = array("Id" => 1779, "SupplierId" => 1809, "SupplierName" => "cccccc");

$arr2 = array(array("Id" => 2020, "SupplierId" => 1809, "SupplierName" => "vvv"),
              array("Id" => 2058, "SupplierId" => 1809, "SupplierName" => "bbb"),
              array("Id" => 2063, "SupplierId" => 1809, "SupplierName" => "xx"));

echo countRes($arr1); // 1
echo countRes($arr2); // 3

It checks if the last element is an array, and returns the number of arrays in the resulting array. Otherwise it returns 1 because the resulting array itself contains the data.

what happen if the case is :-

$arr2 = array(array("Id" => 2020, "SupplierId" => 1809, "SupplierName" => "vvv"),               array("Id" => 2058, "SupplierId" => 1809, "SupplierName" => "bbb"),"Id" => 2063);

? end($arr) will not work i think?

Well, OP did not give a case like that.

yes i know, but i think a good answer need to cover max possibility. BTW your answer is correct for OP senario. +1

@Anant Yeah that would be a better answer. But I'll have to wait for OP's response about this. If he does expect results like that. Anyway thanks. :)

First, a comment. Methods should always return the same type of object. If you can modify the code of the script to always return an array of arrays, please do so.

If you cannot, then hacky solutions are in order.

You can use the typeof operator of php to find if the elements in the first array are integers or more arrays:

$array1 = array ( 'Id' => 1779, 'SupplierId' => 1809, 'SupplierName' => 'cccccc');

$array2 = array(
        array ( 'Id' => 1779, 'SupplierId' => 1809, 'SupplierName' => 'cccccc'),
        array ( 'Id' => 1779, 'SupplierId' => 1809, 'SupplierName' => 'cccccc'),
        array ( 'Id' => 1779, 'SupplierId' => 1809, 'SupplierName' => 'cccccc')
    );

// sub arrays with key
$array3 = array( 
    'first'=>array ( 'Id' => 1779, 'SupplierId' => 1809, 'SupplierName' => 'cccccc'), 
    'second'=>array ( 'Id' => 1779, 'SupplierId' => 1809, 'SupplierName' => 'cccccc'), 
    'third'=>array ( 'Id' => 1779, 'SupplierId' => 1809, 'SupplierName' => 'cccccc') 
    );


echo arrayCount($array3);


function arrayCount($array){
    foreach($array as $key=>$value){
        if(is_array($value)){
            return count($array);
        }else{
            return 1;
        }
    }
}

what happen if the second array is associative multi-dimenaional array? $array[0] will not work. for example:-

$array2 = array(         'first'=>array ( 'Id' => 1779, 'SupplierId' => 1809, 'SupplierName' => 'cccccc'),         'second'=>array ( 'Id' => 1779, 'SupplierId' => 1809, 'SupplierName' => 'cccccc'),         'third'=>array ( 'Id' => 1779, 'SupplierId' => 1809, 'SupplierName' => 'cccccc')     );
