How can I call particular array value of array in php? - php

Question

I'm getting below output as an array.
$array =
Array
(
[12] => Array
(
[1] => Array
(
[14] => Array
(
[0] => Array
(
[name] => Avaya Implementation Services
[service_id] => 14
[ser_type_id] => 1
[service_desc] =>Avaya Implementation Servic
)
)
)
)
);
I want to print only service_desc array value. and I don't want call like $array[12][1][14][0]['service_desc'];
How can I call particular service_desc array value of the array?

Answer 1

As you mentioned that you don't want to call it as $array[12][1][14][0]['service_desc'] you can use extract function which will create variables from your array,
extract($array[12][1][14][0]);
echo $service_desc;
And then you can use your particular key such as service_desc as variable.

Answer 2

You can try this function: (Please optimize as per your requirements)
$arr ="<YOUR ARRAY>";
$val = "service_desc";
echo removekey($arr, $val);
function removekey($arr, $val) {
$return = array();
foreach ($arr as $k => $v) {
if (is_array($v) && $k !== $val) {
removekey($v, $val);
continue;
}
if ($k == $val) {
echo ($arr[$k]);
die;
}
$return[$k] = $v;
}
return $return;
}

You can use array_walk_rescursive to frame a single dimensional array of matching keys:
DEMO
<?php
$array[12][1][14][0]['service_desc'] = 'Avaya Implementation Servic';
$array[12][1][14][0]['service'] = 'dsfasf';
$array[12][1][114][0]['service_desc'] = 'Avaya Implementation Servicasdfdsf';
$searchKey = 'service_desc';
$desiredValues = [];
array_walk_recursive($array, function ($v, $k) use ($searchKey, &$desiredValues) {
if ($k === $searchKey) {
$desiredValues[] = $v;
}
});
print_r($desiredValues);
So this will yield:
Array
(
[0] => Avaya Implementation Servic
[1] => Avaya Implementation Servicasdfdsf
)

Answer 4

You might use the array_walk_recursive function.
array_walk_recursive($array, function ($val, $key) {
if ($key == 'service_desc') print_r($val);
} );
Instead of the print_r statement, you can collect your data into another structure, which you convey using the use statement, or with the $userdata additional parameter (see http://www.php.net/manual/en/function.array-walk-recursive.php ).
$results = array();
array_walk_recursive($array, function ($val, $key) use (&$results) {
if ($key == 'service_desc') {
$results []= $val;
}
} );
Pay extra care to the & in front of the use (&$results) otherwise your array of results will be considered immutable inside the callback (i.e. all changes discarded).

Answer 5

Convert multidimensional array to single array using iterator_to_array
REF: http://php.net/manual/en/function.iterator-to-array.php
$service_desc= iterator_to_array(new RecursiveIteratorIterator(new RecursiveArrayIterator($your_array)), 0);
print_r($service_desc);
Result:
Array
(
[name] => Avaya Implementation Services
[service_id] => 14
[ser_type_id] => 1
[service_desc] =>Avaya Implementation Servic
)
