Similarly if y=6.29452 it should come as 6.3 (3 Replies)

LEARN ABOUT PHP
count
COUNT(3) 1 COUNT(3)count - Count all elements in an array, or something in an objectSYNOPSIS
int count (mixed $array_or_countable, [int $mode = COUNT_NORMAL])
DESCRIPTION
Counts all elements in an array, or something in an object.
For objects, if you have SPL installed, you can hook into count(3) by implementing interface Countable. The interface has exactly one
method, Countable::count, which returns the return value for the count(3) function.
Please see the Array section of the manual for a detailed explanation of how arrays are implemented and used in PHP.
PARAMETERS
o $array_or_countable
- An array or Countable object.
o $mode
- If the optional $mode parameter is set to COUNT_RECURSIVE (or 1), count(3) will recursively count the array. This is particu-
larly useful for counting all the elements of a multidimensional array.
Caution
count(3) 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.
RETURN VALUES
Returns the number of elements in $array_or_countable. If the parameter is not an array or not an object with implemented Countable inter-
face, 1 will be returned. There is one exception, if $array_or_countable is NULL, 0 will be returned.
Caution
count(3) 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(3) to test if a variable is set.
EXAMPLES
Example #1
count(3) example
<?php
$a[0] = 1;
$a[1] = 3;
$a[2] = 5;
$result = count($a);
// $result == 3
$b[0] = 7;
$b[5] = 9;
$b[10] = 11;
$result = count($b);
// $result == 3
$result = count(null);
// $result == 0
$result = count(false);
// $result == 1
?>
Example #2
Recursive count(3) example
<?php
$food = array('fruits' => array('orange', 'banana', 'apple'),
'veggie' => array('carrot', 'collard', 'pea'));
// recursive count
echo count($food, COUNT_RECURSIVE); // output 8
// normal count
echo count($food); // output 2
?>
