怎么改变数组里的值怎么改变数组里的值

Array ( [0] => Array (
[id] => 1
[scenicspoimgs] => Array (
[0] => images/17/2018/03/lJFB4Gs443ib3G3GZsS9ky394bg74E.jpg
[1] => images/17/2018/03/jMv2b67MVMTg52wezWV5B7vehMzhhE.jpg
[2] => images/17/2018/03/nX7V5QzQ3SU5DDD577xXs8rfFsC64S.jpg
[3] => images/17/2018/03/Fkze2eJYkYkyD2S2NJjKshCP6z6qYh.jpg

初学者求大神解答

假设这个数组赋值给变量$arr
1、将ID的值由1改为2:$arr["id"] = 2
2、将images/17/2018/03/lJFB4Gs443ib3G3GZsS9ky394bg74E.jpg
改为csdn.net $arr['scenicspoimgs'][0]='csdn.net';

直接给对应的键赋值即可
例如：
$a = Array (
[id] => 1
[scenicspoimgs] => Array (
[0] => images/17/2018/03/lJFB4Gs443ib3G3GZsS9ky394bg74E.jpg
[1] => images/17/2018/03/jMv2b67MVMTg52wezWV5B7vehMzhhE.jpg
[2] => images/17/2018/03/nX7V5QzQ3SU5DDD577xXs8rfFsC64S.jpg
[3] => images/17/2018/03/Fkze2eJYkYkyD2S2NJjKshCP6z6qYh.jpg
)
)
修改id对应的值，$a['id'] = 4
修改scenicspoimgs里面的值，$a['scenicspoimgs'][0] = 'df'
修改$a的值，重新赋值$a[] = 33
