count   function works with array  But if you want to count object s length then you can use this method    total    obj- gt length

Count Normal  arrya or object  count  object or array      Count multidimensional arrya or object  count  object or array  1      1 for  multidimensional array count  0 for Default

The problem is that count is intended to count the indexes in an array  not the properties on an object   unless it s a custom object that implements the Countable interface   Try casting the object  like below  as an array and seeing if that helps    total   count  array  obj     Simply casting an object as an array won t always work but being a simple stdClass object it should get the job done here

Just use this    i 0  foreach   object as  key   gt  value     i        the variable  i is number of keys

The count function is meant to be used on    Arrays Objects that are derived from classes that implement the countable interface   A stdClass is neither of these   The easier quickest way to accomplish what you re after is    count   count get object vars  some std class object      This uses PHP s get object vars function  which will return the properties of an object as an array   You can then use this array with PHP s count function

The object doesn t have 30 properties  It has one  which is an array that has 30 elements  You need the number of elements in that array

There is nothing wrong with count   here   trends  is the only key that is being counted in this case  you can try doing   count  obj- gt trends     Or   count  obj- gt trends  2009-08-21 11 05       Or maybe even doing   count  obj  COUNT RECURSIVE
