Using the count() method:
$a[0] = 1;
$a[1] = 3;
$a[2] = 5;
$result = count($a);
// $result 1
?>
To find the size of an array in PHP you can either use the count() function or the sizeof() function as they will produce the same result. <?php $array = array(1, 2, 3, 4, 5, 6, 7); echo count($array); // outputs 7 echo sizeof($array); // outputs 7 ?>
To find out how many results there are in a PHP array all you need to do is use the function count() like I have shown you in the example below.
build an array of vowels then do a foreach on the array and then explode the string on the array value and the answer is -1 of the result
number = myfirstfunction (text, freq); // The first function, where "text" is a string, // and "freq" is the array that is filled with data mysecondfunction (number, freq); // The 2:nd function where the value from the previous // function is being used, and the array "freq" is // bring printed.
It cannot be part of the array.
Using the function "count". <?php $foo = array("John", "Jacob", "Jingleheimer", "Schmidt"); echo count($foo); // <-- outputs the number 4 ?>
Passing array elements to a function is achieved by passing the individual elements by reference or by value, just as you would any other variable. However, passing the entire array requires that you pass a pointer-to-pointer to the array along with the dimension(s) of the array.

It 's address is received by the function . that any changes in the value of array elements in the function will result in actual change.
It is better to do this when the function needs to work on the entire array, rather than on individual elements. However, do not pass the array by value; always pass by reference.
The array_map function in PHP loops over each elements of the passed array(s), and runs the given function. It then returns a new array that contains the values returned by each call to the given function.
You can use the LEN function to count characters in a cell. You can also use it to count characters in multiple cells. You need to know how to do array formulas to do that.

An array literal is a comma-separated list of the elements of an array. An array literal can be used for initializing the elements of an array.
You add up all the array elements, then divide by the number of elements. You can use a nested for() loop in Java; inside the inner for() loop, you can both increase a counter (to count how many elements there are), and add to a "sum" variable.
You cannot add elements to a fixed array in C or C++. If, however, the array is declared as a pointer to an array, you can add elements by allocating a new array, copying/adding elements as needed, reassigning the new array to the pointer, and deallocating the original array.
$arr=array(2,5,4,6,7,8,1); for($i=0;$i<count($arr);$i++) { for($j=$i;$j<count($arr);$j++) { if($arr[$i] > $arr[$j]) { $temp=$arr[$i]; $arr[$i]=$arr[$j]; $arr[$j]=$temp; } } }
