原数组：
sdfdsdsdsfrrrrrrr [1] => fdsfdsdsfds [2] => fdsfdsdsfdsds [3] => fdsdsfdsfds [4] => [5] => [6] => [7] => fdsfdsfdsfds [8] => fdsfdsfdsfdsfdsfsd [9] => ssssssss [10] => [11] => sssssssssssssssssssss) ?>
处理之后数组
sdfdsdsdsfrrrrrrr [1] => fdsfdsdsfds [2] => fdsfdsdsfdsds [3] => fdsdsfdsfds [7] => fdsfdsfdsfds [8] => fdsfdsfdsfdsfdsfsd [9] => ssssssss [11] => sssssssssssssssssssss) ?>
使用方法：
去除空元素方法二：（键值自增）
原数组：
sdfdsdsdsfrrrrrrr [1] => fdsfdsdsfds [2] => fdsfdsdsfdsds [3] => fdsdsfdsfds [4] => [5] => [6] => [7] => fdsfdsfdsfds [8] => fdsfdsfdsfdsfdsfsd [9] => ssssssss [10] => [11] => sssssssssssssssssssss )
处理之后数组：
Array ( [0] => sdfdsdsdsfrrrrrrr [1] => fdsfdsdsfds [2] => fdsfdsdsfdsds [3] => fdsdsfdsfds [4] => fdsfdsfdsfds [5] => fdsfdsfdsfdsfdsfsd [6] => ssssssss [7] => sssssssssssssssssssss )
使用方法：
$arr = array();
foreach ($urlArr as $key => $val) {
if (empty($val)) {
continue;
}
$arr[] = $val;
