How to count all elements or values in an array in PHP
Answer: Use the PHP
You can simply use the PHP
sizeof() function to get the number of elements or values in an array. The
sizeof() function returns 0 for a variable that has been initialized with an empty array, but it may also return 0 for a variable that isn't set.
You can additionally use the
isset() function to check whether a variable is set or not.
