i have an json and i changed to array.
$asm1n = json_decode($asm_1);
print_r ($asm1n);
the result is
Array ( [0] => 2 [1] => 3 )
my problem is how to change it value based static value :
if it, 1 change to orange, 2 change apple, 3 change mango automatically
currently the value is like this in json:
["2","3"]
what i want to know how to make condition if the value like above it auto change to :
["apple","mango"]
i try use below code but i thing is wrong :
if ($asm1n == ["1","2","3"]){
$asm1n = "["orange","apple","mango"]";
}
this all data come from database, it might have value like this ["2","3"] , ["1","2","3"], ["1","3"].
how to change the number to the value like i said before? automatically or by if condition?
Try this:
$asm1n = ["2", "3"];
$data = array();
foreach( $asm1n as $key => $value ) {
if ( "1" === $value ) {
$data[] = "orange";
} elseif ( "2" === $value ) {
$data[] = "apple";
} elseif ( "3" === $value ) {
$data[] = "mango";
}
}
print_r($data);
You just need to ensure that you have the values and to use them to get your output
$myValues = [
1 => "orange",
2 => "apple",
3 => "mango"
];
$rawValues = json_decode($asm_1);
$asm1n = [];
foreach ($rawValues as $value) {
$asm1n[]=$myValues[$value];
}
print_r ($asm1n);
You could loop through your array and change it accordingly.
$fruits = [
1 => 'orange',
2 => 'apple',
3 => 'mango'
];
foreach($asm1n as &$value){
foreach($fruits as $key => $fruit){
if($value==$key){
$value = fruit;
}
}
}

Here is my array:
$arr = [
1 => [
2 => "something",
3 => "something else"
],
2 => "foo br"
];
I need to restart all keys and start all of them from 0. Based on some researches, I figured out I have to use array_values() function. But it just makes the keys of outer array re-index, See.
How can I apply it on the all keys of array? (even nested ones)
You can use array_values + recursively calling custom function:
function arrayValuesRecursive($array) {
$array = array_values($array);
$countValues = count($array);
for ($i = 0; $i < $countValues; $i++ ) {
$subElement = $array[$i];
if (is_array($subElement)) {
$array[$i] = arrayValuesRecursive($subElement);
}
}
return $array;
}
$restructuredArray = arrayValuesRecursive($array);
You can implement it using recursion like this:
function reIndex($arr) {
$arr = array_values($arr);
foreach ($arr as $k => $v) {
if (is_array($v)) {
$arr[$k] = reIndex($v);
}
}
return $arr;
}
$arr = reIndex($arr);
Hi checkout following code
<?php
$arr = [
1 => [
2 => "something",
3 => "something else"
],
2 => "foo br"
];
$reIndexedArray = array();
foreach($arr as $arrItr){
$reIndexedArray[] = count($arrItr) > 1 ? array_values($arrItr) : $arrItr;
}
print_r($reIndexedArray);
?>
output is
Array
(
[0] => Array
(
[0] => something
[1] => something else
)
[1] => foo br
)
I have two sets of arrays coming from $_POST. Keys for both will be numeric and the count will be the same, since they come in pairs as names and numbers:
$_POST[names]
(
[0] => First
[1] => Second
[2] =>
[3] => Fourth
)
$_POST[numbers]
(
[0] => 10
[1] =>
[2] => 3
[3] => 3
)
Now I need to combine those two, but remove each entry where either values are missing.
The result should be something like:
$finalArray
(
[First] => 10
[Fourth] => 3
)
Post data is dynamically created so there might be different values missing based on user input.
I tried doing something like:
if (array_key_exists('names', $_POST)) {
$names = array_filter($_POST['names']);
$numbers = array_filter($_POST['numbers']);
if($names and $numbers) {
$final = array_combine($names, $numbers);
}
}
But I can't seem to filter it correctly, since its giving me an error:
Warning: array_combine(): Both parameters should have an equal number of elements
How about using array_filter with ARRAY_FILTER_USE_BOTH flag on?
<?php
$array1 = [
0 => "First",
1 => "Second",
2 => "",
3 => "Fourth",
];
$array2 = [
0 => 10,
1 => "",
2 => 3,
3 => 3,
];
var_dump(array_filter(array_combine($array1, $array2), function($value, $key) {
return $key == "" || $value == "" ? false : $value;
}, ARRAY_FILTER_USE_BOTH ));
/*
Output:
array(2) {
["First"]=>
int(10)
["Fourth"]=>
int(3)
}
*/
Here's a fun way:
$result = array_flip(array_flip(array_filter(array_combine($_POST['names'],
$_POST['numbers']))));
// create array using $_POST['names'] as keys and $_POST['numbers'] as values
$result = array_combine($_POST['names'], $_POST['numbers']);
// remove entries that have empty values
$result = array_filter($result);
// remove entry with empty key
unset($result[null]);
print_r($result);
If both arrays will have the same count, and the keys will always be numeric, you could do the following:
$total = count($_POST['names']);
$final = array();
for ($i = 0; $i < $total; $i++) {
if (trim($_POST['names'][$i]) != '' && trim($_POST['numbers'][$i]) != '') {
$final[$_POST['names'][$i]] = $_POST['numbers'][$i];
}
}
Or if you prefer to use a foreach instead of for
$final = array();
foreach ($_POST['names'] as $key => $value) {
if (trim($value) != '' && trim($_POST['numbers'][$key]) != '') {
$final[$value] = $_POST['numbers'][$key];
}
}
Takeing your previous information into account:
both keys will be numeric and the count will be the same, since they come in pairs as names and numbers
$myNewArray = array();
$count = 0;
foreach ($_POST['names'] as $bufferArray)
{
if (($bufferArray[$count]!=NULL)&&($_POST['numbers][$count]!=NULL))
{
array_push($myNewArray, array($bufferArray[$count] => $_POST['numbers][$count]);
}
$count++;
}
Let me know if that helps! :)
Note: I made some edits to the code.
Also, my previous code checks if the empty array spaces are NULL. If you want to check if they are either NULL or "" (empty), then replace the line of code with:
if (($bufferArray[$count]!=NULL)&&($_POST['numbers][$count]!=NULL)&&($bufferArray[$count]!="")&&($_POST['numbers][$count]!=""))
{...}
I have array multidimensional code like this:
$array = [
'fruits' => ['apple','orange','grape', 'pineaple'],
'vegetables' => ['tomato', 'potato']
];
$eaten = 'grape';
unset($array[$eaten]);
and what i need is to delete 'grape' from the array because 'grape' already eaten. how to fix my code to unset the 'grape'?
and my question number two, if it can be unset, is there a way to unset multi value like
unset($array,['grape','orange']);
thanks for help..
You can remove eaten element by following way. Use array_search() you can find key at the position of your eaten element.
Here below code shows that in any multidimensional array you can call given function.
$array = [
'fruits' => ['apple','orange','grape', 'pineaple'],
'vegetables' => ['tomato', 'potato']
];
$eaten = 'grape';
$array = removeElement($array, $eaten);
function removeElement($data_arr, $eaten)
{
foreach($data_arr as $k => $single)
{
if (count($single) != count($single, COUNT_RECURSIVE))
{
$data_arr[$k] = removeElement($single, $eaten);
}
else
{
if(($key = array_search($eaten, $single)) !== false)
{
unset($data_arr[$k][$key]);
}
}
}
return $data_arr;
}
P.S. Please note that you can unset() multiple elements in single call. But the way you are using unset is wrong.
Instead of using unset() i suggest you to create a new Array after removal of required value benefit is that, your original array will remain same, you can use it further:
Example:
// your array
$yourArr = array(
'fruits'=>array('apple','orange','grape', 'pineaple'),
'vegetables'=>array('tomato', 'potato')
);
// remove array that you need
$removeArr = array('grape','tomato');
$newArr = array();
foreach ($yourArr as $key => $value) {
foreach ($value as $finalVal) {
if(!in_array($finalVal, $removeArr)){ // check if available in removal array
$newArr[$key][] = $finalVal;
}
}
}
echo "<pre>";
print_r($newArr);
Result:
Array
(
[fruits] => Array
(
[0] => apple
[1] => orange
[2] => pineaple
)
[vegetables] => Array
(
[0] => potato
)
)
Explanation:
Using this array array('grape','tomato'); which will remove the value that you define in this array.
This is how I would do it.
$array = [
'fruits' => ['apple','orange','grape', 'pineaple'],
'vegetables' => ['tomato', 'potato']
];
$unset_item = 'grape';
$array = array_map(function($items) use ($unset_item) {
$found = array_search($unset_item, $items);
if($found){
unset($items[$found]);
}
return $items;
}, $array);
Might be a newbie question but I've been trying to figure this problem and it's doing my head in.
I have the following array :
[0] => Array
(
[provisionalBookingRoomID] => 1
[totalSpecificRoomCount] => 2
)
[1] => Array
(
[provisionalBookingRoomID] => 2
[totalSpecificRoomCount] => 5
)
I need a php function that searches through the array for the value of 'provisionalBookingRoomID' and returns the value of 'totalSpecificRoomCount'
basically something like the following
getProvisionalTotalRoomsCount($currentRoom, $arrayOfRooms);
// getProvisionalTotalRoomsCount('1', $arrayOfRooms) should return 2;
Any ideas?
Check this:
getProvisionalTotalRoomsCount($currentRoom, $arrayOfRooms){
foreach($arrayOfRooms as $key=>$value){
if($value['provisionalBookingRoomID'] == $currentRoom){
return $value['totalSpecificRoomCount'];
}
}
}
For anyone looking for a generic function :
function findValueInArray($array, $searchValue, $searchKey, $requiredKeyValue) {
foreach($array as $key=>$value){
if($value[$searchKey] == $searchValue){
return $value[$requiredKeyValue];
}
}
}
// Usage : findValueInArray($provisionalBookedRoomsArray, '1', 'provisionalBookingRoomID', 'totalSpecificRoomCount');
If you are likely to work with more than one value, you could build a new array with a 1->1 map for those attributes.
<?php
$items = array(
array(
'name' => 'Foo',
'age' => 23
),
array(
'name' => 'Bar',
'age' => 47
)
);
// Php 7
$name_ages = array_column($items, 'name', 'age');
echo $name_ages['Foo']; // Output 23
// Earlier versions:
$name_ages = array();
foreach($items as $value)
{
$name_ages[$value['name']] = $value['age'];
}
echo $name_ages['Foo']; // Output 23
$value = 0;
$array = array(array("provisionalBookingRoomID"=>1,"totalSpecificRoomCount"=>2),array("provisionalBookingRoomID"=>2,"totalSpecificRoomCount"=>5));
array_map(
function($arr) use (&$value) {
if($arr['provisionalBookingRoomID']==1) {
$value = $arr['totalSpecificRoomCount'];
}
},$array
);
echo $value;
Suppose I have an array like this:
$array = array("a","b","c","d","a","a");
and I want to get all the keys that have the value "a".
I know I can get them using a while loop:
while ($a = current($array)) {
if ($a == 'a') {
echo key($array).',';
}
next($array);
}
How can I get them using a foreach loop instead?
I've tried:
foreach ($array as $a) {
if ($a == 'a') {
echo key($array).',';
}
}
and I got
1,1,1,
as the result.
If you would like all of the keys for a particular value, I would suggest using array_keys, using the optional search_value parameter.
$input = array("Foo" => "X", "Bar" => "X", "Fizz" => "O");
$result = array_keys( $input, "X" );
Where $result becomes
Array (
[0] => Foo
[1] => Bar
)
If you wish to use a foreach, you can iterate through each key/value set, adding the key to a new array collection when its value matches your search:
$array = array("a","b","c","d","a","a");
$keys = array();
foreach ( $array as $key => $value )
$value === "a" && array_push( $keys, $key );
Where $keys becomes
Array (
[0] => 0
[1] => 4
[2] => 5
)
You can use the below to print out keys with specific value
foreach ($array as $key=>$val) {
if ($val == 'a') {
echo $key." ";
}
}
here's a simpler filter.
$query = "a";
$result = array_keys(array_filter($array,
function($element)use($query){
if($element==$query) return true;
}
));
use
foreach($array as $key=>$val)
{
//access the $key as key.
}
