利用array_filter过滤数组空值

<?php
    
$array = array(
    0 => '霜天部落',
    1 => false,
    2 => 1,
    3 => null,
    4 => '',
    5 => 'http://www.hzhuti.com',
    6 => '0'
);
$rs = array_filter($array);
print_r($rs);
/*
输出结果为:
Array
(
	[0] => 霜天部落
	[2] => 1
	[5] => http://www.hzhuti.com
)
*/
    
//计算数组不为空元素个数的方法
$cou = count(array_filter($array));
print_r($cou); 
//输出结果：3
