Redis access to PHP multidimensional arrays example

PHP array is actually a hash table, Redis does not seem to support two-dimensional arrays, but you can use Hmset to save the PHP array as a hash type of data, using Hmget to read a one-dimensional key is no problem, reading two-dimensional multidimensional keys return false.

$hset = Array (

' wust ' => ' WUHAN SI ',

' birth ' =>1031,

' Marray ' =>array ' (

' apple ' => ' apples '), 

' orange ' => ' org ',)

;

Dump ($redis->hmset (' Tuntun ', $hset))//save array as hash type

dump ($redis->hmget (' Tuntun ', Array (' birth ')) ;//Fetch the value of an array birth, OK

dump ($redis->hmget (' Tuntun ', Array (' Marry ', ' apple '));//Remove the value of apple from the two-dimensional array marray. return False

Even if you use the Hgetall method:

Dump ($redis->hgetall (' Hset_tuntun '));
The results are as follows:

Array (3) {
["Wust"] => string (8) "WUHAN SI"
["Birth"] => string (4) "1031"
["Marray"] => string (5) "Array"
}

Two-dimensional arrays cannot be displayed. So Redis does not support access to multidimensional arrays of PHP.

The solution is: if you want to use Redis to save multidimensional arrays, you can convert the array json_encode into JSON-type data, stored in string style. Read the time again Json_decode back.
