I have some JSON data, it is apairing like this now
[
[
{
'key': 'value'
},
{
'key': 'value'
}
]
]
What I want to do, is remove the second square bracket from here like this:
[
{
'key': 'value'
},
{
'key': 'value'
}
]
I've applied some algorithms in both PHP and javascript but it does not work please help me if you know how to solve this
You can use the array_merge() PHP method like this (PHP 7.4 or above)
EDIT: Decode the JSON string using json_decode() php function before.
$flattened_array = array_merge(...$arr);
https://wiki.php.net/rfc/spread_operator_for_array
https://www.php.net/manual/pt_BR/function.array-merge.php
Or simply do this:
$arr = "[
[
{
'key': 'value'
},
{
'key': 'value'
}
]
]" //receives a JSON string;
$flattened_arr = json_decode($arr[0]) //decodes it;
