PHP数据结构——线性表的删除

function delete_array_element($arr,$i) {
$len = count($arr);
for($j=$i; $j<$len; $j++) {
$arr[$j] = $arr[$j+1];
}
array_pop($arr);//将数组的最后一个单元弹出
return $arr;
}
for($i=0; $i<10; $i++) {
$arr1[$i] = $i+1;
}
print_r($arr1);
echo "<br>";
print_r(delete_array_element($arr1,5));
输出结构：
Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 5 [5] => 6 [6] => 7 [7] => 8 [8] => 9 [9] => 10 )
Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 5 [5] => 7 [6] => 8 [7] => 9 [8] => 10 )
