SplFixedArray::count — Returns the size of the array
Returns the size of the array.
此函数没有参数。
Returns the size of the array.
Example #1 SplFixedArray::count() example
<?php
$array = new SplFixedArray ( 5 );
echo $array -> count () . "\n" ;
echo count ( $array ) . "\n" ;
?>
以上例程会输出:
5 5
Note:
This method is functionally equivalent to SplFixedArray::getSize() .
Note:
The count of elements is always equal to the set size because all values are initially initialized with
NULL
.
