Count Array PHP Overview
- The PHP count() function is used to Count Array Elements in PHP, or also you can say that the count() function is used to get get the number of elements or values in an array. this function returns the number of items in the array.
- PHP array count() method is basically used to count the items of an array or the properties of an object.
- if the function returns 0 for a variable that has been initialized with an empty array. furthermore, if the array is not initialized, then you will see an error. In that case, you can use the PHP isset() function to check whether a variable is set or not.
- For an object, if you have installed SPL, then you can hook into count() by implementing the interface Countable. The interface has only one method, Countable::count(), which returns a return value for the count() function.
