删除指定数组下标元素我们利用unset函数来实现,下在看看关于unset语法
void unset ( mixed var [, mixed var [, ...]])

unset() 销毁指定的变量。注意在 php教程 3 中,unset() 将返回 true(实际上是整型值 1

 

$array = array(1=>'1',2=>'2',3=>'3',4=>'5',5=>'6');
print_r( $array );



array
(
    [1] => 1
    [2] => 2
    [3] => 3
    [4] => 5
    [5] => 6
)

unset( $array[2]);
print_r($array);

array
(
    [1] => 1
    [3] => 3
    [4] => 5
    [5] => 6
)
