count Count elements in an array, or properties in an object &reftitle.description; intcount mixedvar intmode Counts elements in an array, or properties 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, 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; var The array. 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. The default value for mode is 0. count does not detect infinite recursion. &reftitle.returnvalues; Returns the number of elements in var, which is typically an array, since anything else will have one element. If var is not an array or an object with implemented Countable interface, 1 will be returned. There is one exception, if var is &null;, 0 will be returned. count may return 0 for a variable that isn't set, but it may also return 0 for a variable that has been initialized with an empty array. Use isset to test if a variable is set. &reftitle.changelog; &Version; &Description; 4.2.0 The optional mode parameter was added. &reftitle.examples; <function>count</function> example ]]> 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.seealso; is_array isset strlen
