I have the following array:
array(15) {
[0]=> object(stdClass)#317 (2) { ["id"]=> string(1) "2" ["value"]=> string(1) "1" }
[1]=> object(stdClass)#316 (2) { ["id"]=> string(1) "3" ["value"]=> string(531) "awfaww" }
[2]=> object(stdClass)#315 (2) { ["id"]=> string(1) "4" ["value"]=> string(1) "1" }
[3]=> object(stdClass)#318 (2) { ["id"]=> string(1) "5" ["value"]=> string(1) "1" }
[4]=> object(stdClass)#319 (2) { ["id"]=> string(1) "6" ["value"]=> string(1) "1" }
[5]=> object(stdClass)#320 (2) { ["id"]=> string(1) "7" ["value"]=> string(1) "1" }
[6]=> object(stdClass)#321 (2) { ["id"]=> string(1) "8" ["value"]=> string(1) "1" }
[7]=> object(stdClass)#322 (2) { ["id"]=> string(2) "30" ["value"]=> string(8) "12:30:02" }
[8]=> object(stdClass)#323 (2) { ["id"]=> string(2) "31" ["value"]=> string(8) "18:12:00" }
[9]=> object(stdClass)#324 (2) { ["id"]=> string(2) "11" ["value"]=> string(10) "2014-06-17" }
[10]=> object(stdClass)#325 (2) { ["id"]=> string(2) "12" ["value"]=> string(10) "2014-06-26" }
[11]=> object(stdClass)#326 (2) { ["id"]=> string(2) "14" ["value"]=> string(1) "2" }
[12]=> object(stdClass)#327 (2) { ["id"]=> string(2) "15" ["value"]=> string(1) "2" }
[13]=> object(stdClass)#328 (2) { ["id"]=> string(2) "16" ["value"]=> string(1) "4" }
[14]=> object(stdClass)#329 (2) { ["id"]=> string(2) "17" ["value"]=> string(1) "5" }
}
I would like to get a specific value from this array using the ID. For example, if the ID: 11 is found in the array I want to retrieve its value. How can I do this?
Try something like this:
<?php
function findById($array, $id) {
foreach ($array as $value) {
if ($value->id == $id) {
return $value->value;
}
}
return null;
}
$result = findById($yourArray, 11);
?>
if the array is static for each run - i'd suggest changing the array into "key"=>"value" array, using this:
$new_arr = array();
foreach($original_array as $object) {
$new_arr[$object->id] = $object->value;
}
and then you can just use $new_arr[id]
, instead of searching the whole original array each time.
You can use array_filter
:
array_filter($arr, function($i) { return $i->id == '11'; });
