php - Get nr of items in an array -

i have array has format:

array(   info(     date-today => '09/04/2013'   )   clients(     id => 1001,     name => fred   )   more_info(     weather-today => "cloudy"   ) ) 

but sometimes, receive data more clients:

array(   info(     date-today => '08/04/2013'   )   clients(     0(       id => 1001,       name => fred     ),     1(       id => 1045,       name => fritz     )   )   more_info(     weather-today => "sunny"   ) ) 

i want count how many cients got returned, because need access client-data differently if there 1 or more one. tried several "count()" options, such as:

count(array['client']) 

but of course if there 1 client, doesn't return 1, returns 2 (since there 2 items of client-data in array).

any tips?

you have find out whether $array['clients'] has numeric indices:

$size = count($array['clients']; if (count(array_filter(array_keys($array['clients']), 'is_int')) == $size) {     return $size; } else {     return 1; } 

alternatively, use existence of one numeric index condition:

if (isset($array['clients'][0])) {     return count($array['clients']); } else {     return 1; }
