I have an array like
[{"detail":"33,putih","sku":"123","price":"500000","stok":"8"},{"detail":"33,hitam","sku":"123","price":"500000","stok":"5"},{"detail":"43,hitam","sku":"123","price":"1000000","stok":"1"}]
i have to json_decode it.
i want to change stok = 2 from detail "33,hitam".
but i'm seriously confused to use array search first and use array replace.
You could do it like this :
$stringarray = '[{"detail":"33,putih","sku":"123","price":"500000","stok":"8"},{"detail":"33,hitam","sku":"123","price":"500000","stok":"5"},{"detail":"43,hitam","sku":"123","price":"1000000","stok":"1"}]';
$array = json_decode($stringarray);
var_dump($array);
$replaced = replaceInObject($array, "detail", "33,hitam", "stok" , "2");
var_dump($replaced);
function replaceInObject($array, $field, $searchvalue, $valuefield, $newvalue){
foreach($array as $element){
if($element->$field == $searchvalue){
$element->$valuefield = $newvalue;
}
}
return $array;
}
You can use array_map to achieve this
$data = '[{"detail":"33,putih","sku":"123","price":"500000","stok":"8"},{"detail":"33,hitam","sku":"123","price":"500000","stok":"5"},{"detail":"43,hitam","sku":"123","price":"1000000","stok":"1"}]';
$json = json_decode($data, true);
$result = array_map(function($e) {
if ($e['detail'] == "33,hitam") $e['stok'] = "2";
return $e;
}, $json);

My Code:
$finalArray = json_encode($loanTypeCount);
Output:
[{"name":"Salary","y":"6"},{"name":"Emergency","y":"1"}]
Desired Output:
[{"name":"Salary","y":6, "selected": true},{"name":"Emergency","y":1, "selected": true}]
Inserted "selected": true key value pair. What is the way to do it in laravel/php?
If it's a Collection instance, you can do it with map()
$loanTypeCount->map(function($loan) {
$loan->selected = true;
return $loan;
});
Based on N69S' solution, here an example starting with a JSON encoded string instead of a collection instance and ending with a modified one.
$json = '[{"name":"Salary","y":"6"},{"name":"Emergency","y":"1"}]';
$arr = collect(json_decode($json, true))
->map(function ($item, $key) {
$item['selected'] = true;
return $item;
})
->toJson();
Simple solution with pure php:
$json = '[{"name":"Salary","y":"6"},{"name":"Emergency","y":"1"}]';
$obj=json_decode($json);
$obj[0]->selected = true;
$obj[1]->selected = true;
$newJson = json_encode($obj);
//[{"name":"Salary","y":"6","selected":true},{"name":"Emergency","y":"1","selected":true}]
Alternatively with foreach:
$json = '[{"name":"Salary","y":"6"},{"name":"Emergency","y":"1"}]';
foreach($obj=json_decode($json) as $key => $item){
$obj[$key]->selected = true;
}
$newJson = json_encode($obj);
//[{"name":"Salary","y":"6","selected":true},{"name":"Emergency","y":"1","selected":true}]
I have a MYSQL query that fetches an array of dictionaries or results which are returned via JSON in an api. In some cases, I would like to change the name of the dictionary keys in the results array.
For example, in the following case:
$var = '[{"player":"Tiger Woods"},{"player":"Gary Player"}]';
I would like to change it to:
$var = '[{"golfer":"Tiger Woods"},{"golfer":"Gary Player"}]'
It is not practical in this case to change the mysql query so I'd just like to replace the word "player" with the word "golfer" for the keys without disturbing the values.
In the above example, I would not want to change Gary Player's name so just using str_replace does not seem like it would work.
Is there a way to change all of the keys from "player" to "golfer" without changing any of the values?
Here is the snippet you can use
$var = '[{"player":"Tiger Woods"},{"player":"Gary Player"}]';
// json decode the json string
$temp = json_decode($var, true);
$temp = array_map(function($item){
// combining key and values
return array_combine(['golfer'], $item);
}, $temp);
print_r($temp);
// or echo json_encode($temp);
Demo.
Some argue that foreach is fastest,
foreach($temp as $k => &$v){
$v = array_combine(['golfer'], $v);
}
print_r($temp);
Demo.
Little hardcoded if more than one keys in single array,
foreach ($temp as $k => &$v){
$v['golfer'] = $v['player'];
unset($v['player']);
}
print_r($temp);
Demo.
Using recursion
function custom($arr, $newKey, $oldKey)
{
// if the value is not an array, then you have reached the deepest
// point of the branch, so return the value
if (!is_array($arr)) {
return $arr;
}
$result = []; // empty array to hold copy of subject
foreach ($arr as $key => $value) {
// replace the key with the new key only if it is the old key
$key = ($key === $oldKey) ? $newKey : $key;
// add the value with the recursive call
$result[$key] = custom($value, $newKey, $oldKey);
}
return $result;
}
$var = '[{"player":"Tiger Woods"},{"player":"Gary Player"}]';
$temp = json_decode($var, true);
$temp = replaceKey($temp, 'golfer', 'player');
print_r($temp);
Demo & source.
Using json way,
function json_change_key($arr, $oldkey, $newkey) {
$json = str_replace('"'.$oldkey.'":', '"'.$newkey.'":', json_encode($arr));
return json_decode($json, true);
}
$temp = json_change_key($temp, 'player', 'golfer');
print_r($temp);
Demo
If you want multiple key replace, here is the trick,
$var = '[{"player":"Tiger Woods", "wins":"10","losses":"3"},{"player":"Gary Player","wins":"7", "losses":6}]';
$temp = json_decode($var, true);
function recursive_change_key($arr, $set)
{
if (is_array($arr) && is_array($set)) {
$newArr = [];
foreach ($arr as $k => $v) {
$key = array_key_exists($k, $set) ? $set[$k] : $k;
$newArr[$key] = is_array($v) ? recursive_change_key($v, $set) : $v;
}
return $newArr;
}
return $arr;
}
$set = [
"player" => "golfers",
"wins" => "victories",
"losses" => "defeats"
];
$temp = recursive_change_key($temp, $set);
print_r($temp);
Demo.
$a = '[{"player":"Tiger Woods"},{"player":"Gary Player"}]';
$array = json_decode($a, true);
foreach($array as $key=>$value){
if(array_keys($value)[0] === "player"){
$array[$key] = ["golfer" => array_values($value)[0]];
};
}
echo json_encode($array);
you can write the value of the key to a new key and then delete the old.
renaming a key called "a" to "b", while keeping the value.
var json = {
"a" : "one"
}
json["b"] = json["a"];
delete json["a"];
for your example, just use this with a loop.

I have a JSON array. I want to delete the entry that have number 4 and return the left over array
$filters = '{"1":1,"2":2,"3":4}';
$fobj = json_decode($filters, TRUE);
foreach($fobj as $key => $value)
{
if (in_array(4, $fobj)) {
unset($fobj[4]);
}
}
echo $filters = json_encode($fobj );
But this echo does not give me what I want. I want it to return something like this:
{"1":1,"2":2}
You're removing the fourth value of the array, not the value. Use array_search instead
$filters = '{"1":1,"2":2,"3":4}';
$fobj = json_decode($filters, TRUE);
$search = array_search(4, $fobj);
if($search !== false) unset($fobj[$search]);
echo $filters = json_encode($fobj );
$index = array_search("4", $array);
unset($array[$index]);

That's all. Hope it helps!
This is my $data variable:
cv = 1,2,3,4,5:::cpt = 4,5 ...
Now I need some function, where I can add the number as param (number will be $data number value).
for example.
function getPermission($id) {
... return $something;
}
Then if I call the function like: echo getPermission(4); it'll print out the data 'keys' where the 4 will be inside, as a value.
So, to be clear:
if I call the function like this:
echo getPermission(4); output will be "cv" and "cpt".
but if I call it this way:
echo getPermission(1);
it'll only output "cv" because number (1) is located in the cv key.
Hope you guys understand, feel free to ask if something aren't clear enough.
$str = 'cv = 1,2,3,4,5:::cpt = 4,5';
$tmp = explode(':::', $str);
$data = array();
foreach ($tmp as $arr) {
$tokens = explode(' = ', $arr);
$data[$tokens[0]] = explode(',', $tokens[1]);
}
print_r(getPermission(4, $data));
print_r(getPermission(1, $data));
function getPermission($id, $data) {
$out = array();
foreach ($data as $key => $arr) {
if (in_array($id, $arr)) $out[] = $key;
}
return $out;
}
I have a multidimensional array:
$array=array( 0=>array('text'=>'text1','desc'=>'blablabla'),
1=>array('text'=>'text2','desc'=>'blablabla'),
2=>array('text'=>'blablabla','desc'=>'blablabla'));
Is there a function to return a monodimensional array based on the $text values?
Example:
monoarray($array);
//returns: array(0=>'text1',1=>'text2',2=>'blablabla');
Maybe a built-in function?
This will return array with first values in inner arrays:
$ar = array_map('array_shift', $array);
For last values this will do:
$ar = array_map('array_pop', $array);
If you want to take another element from inner array's, you must wrote your own function (PHP 5.3 attitude):
$ar = array_map(function($a) {
return $a[(key you want to return)];
}, $array);
Do it like this:
function GetItOut($multiarray, $FindKey)
{
$result = array();
foreach($multiarray as $MultiKey => $array)
$result[$MultiKey] = $array[$FindKey];
return $result;
}
$Result = GetItOut($multiarray, 'text');
print_r($Result);
Easiest way is to define your own function, with a foreach loop. You could probably use one of the numerous php array functions, but it's probably not worth your time.
The foreach loop would look something like:
function monoarray($myArray) {
$output = array();
foreach($myArray as $key=>$value) {
if( $key == 'text' ) {
$output[] = $value;
}
}
return $output;
}
If the order of your keys never changes (i.e.: text is always the first one), you can use:
$new_array = array_map('current', $array);
Otherwise, you can use:
$new_array = array_map(function($val) {
return $val['text'];
}, $array);
Or:
$new_array = array();
foreach ($array as $val) {
$new_array[] = $val['text'];
}
Try this:
function monoarray($array)
{
$result = array();
if (is_array($array) === true)
{
foreach (new RecursiveIteratorIterator(new RecursiveArrayIterator($array)) as $value)
{
$result[] = $value;
}
}
return $result;
}
With PHP, you only have to use the function print_r();
So --> print_r($array);
Hope that will help you :D
