PHP Function count()
Syntax
Definition and Usage
Count elements in an array, or properties in an object.
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.
Paramters
Parameter | Description |
array | Required. Specifies an array |
mode | Optional. Specifies the mode of the function. |
Return Value
Returns the number of elements in an array.
Example
Try out following example:
<?php
$a[0] = 1;
$a[1] = 3;
$a[2] = 5;
$result = count($a);
print($result);
?>
