count Count all elements in an array, or something in an object &reftitle.description; intcount Countablearrayvalue intmodeCOUNT_NORMAL Counts all elements in an array, or something in an object. For objects, if you have SPL installed, you can hook into count by implementing interface Countable. The interface has exactly one method, Countable::count, which returns the return value for the count function. Please see the Array section of the manual for a detailed explanation of how arrays are implemented and used in PHP. &reftitle.parameters; value An array or Countable object. mode If the optional mode parameter is set to COUNT_RECURSIVE (or 1), count will recursively count the array. This is particularly useful for counting all the elements of a multidimensional array. count can detect recursion to avoid an infinite loop, but will emit an E_WARNING every time it does (in case the array contains itself more than once) and return a count higher than may be expected. &reftitle.returnvalues; Returns the number of elements in value. When the parameter is neither an array nor an object with implemented Countable interface, 1 will be returned. There is one exception, if value is &null;, 0 will be returned. &reftitle.examples; <function>count</function> example ]]> &example.outputs; Recursive <function>count</function> example array('orange', 'banana', 'apple'), 'veggie' => array('carrot', 'collard', 'pea')); // recursive count echo count($food, COUNT_RECURSIVE); // output 8 // normal count echo count($food); // output 2 ?> ]]> &reftitle.changelog; &Version; &Description; 7.2.0 count will now yield a warning on invalid countable types passed to the value parameter. &reftitle.seealso; is_array isset empty strlen is_countable
