Array helper: dot search - iRedds - 04-25-2022
The dot_array_search() function has strange behavior.
I am expecting a value that matches the key, or null if the key is not found. But
PHP Code:
dot_array_search('a.b.c', ['a' => ['b' => ['c' => 'c']) // return "c". Ok
dot_array_search('a.b.c', ['a' => ['b' => ['c']) // return "null". Ok. because the key "c" does not exist.
dot_array_search('a.b.c', ['a' => ['b' => 'b']) // return "b". why? key "c" does not exist and should return "null"
//but if we replace "b" with wildcard "*"
dot_array_search('a.*.c', ['a' => ['b' => 'b']) // return "null". Ok
dot_array_search('a.*.c', ['a' => ['b' => []]) // return "null". Ok
//but
dot_array_search('a.*.c', ['a' => []) // return "empty array" ??

I haven't really looked at it, but is the function expecting the user to at least provide an array with the correct number of levels? You'll have to wait for a CI4 to elaborate.

Find exact you must use function array_deep_search()
Code:
array_deep_search('a.b.c', ['a' => ['b' => 'b']]); //return b
array_deep_search('a.*.c', ['a' => []]); //return NULLRE: Array helper: dot search - kenjis - 04-30-2022
I don't know why.
I created an issue.
