how to reach into PHP nested arrays?
Question by user837208
I’ve a nested array whose print_r looks like this-
Array
(
[keyId] => Array
(
[hostname] => 192.168.1.127
[results] => Array
(
[1] => false
[2] => false
[3] => false
)
[sessionIDs] => Array
(
[0] => ed9f79e4-2640-4089-ba0e-79bec15cb25b
)
)
I would like to process(print key and value) of the “results” array. How do I do this?
I am trying to use array_keys function to first get all the keys and if key name is “results”, process the array. But problem is array_keys is not reaching into the “results”
Answer by Jon
foreach($array['keyId']['results'] as $k => $v) {
// use $k and $v
}

One way to navigate through the array is this.
//Assuming, your main array is $array
foreach($array as $value) { //iterate over each item
if(isset($value['results']) && count($value['results'])) {
// ^ check if results is present
//Now that we know results exists, lets use foreach loop again to get the values
foreach($value['result'] as $k => $v) {
//The boolean values are now accessible with $v
}
}
}
