i have arrays like this
Array(
[0] => Array(
[member_name] => hohoho
[member_type] => SUPPLIER
[interest] => Array(
[0] => HOLIDAY
[1] => MOVIES)
),
[1] => Array(
[member_name] => jajaja
[member_validity] => 13/12/2001
[interest] => Array(
[0] => SPORTS
[1] => FOODS)
)
)
how can I put the array keys and items in a separate variable? for example, i want to have something like
$keyholder[0] = member_name,member_type,interest
$keyholder[1] = member_name,member_validity,interest
$itemholder[0] = hohoho,SUPPLIER,{HOLIDAY,MOVIES}
$itemholder[1] = jajaja,13/12/2001,{SPORTS,FOODS}
Try array_keys() and array_values()
http://php.net/manual/en/function.array-keys.php
http://www.php.net/manual/en/function.array-values.php
You can cycle through an array and get the key and values like this:
foreach ($array as $key => $val)
{
echo $key." - ".$val."<br/>";
}
$keyholder=array();
$itemholder=array();
foreach($original_array as $values){
$inner_keys=array();
$inner_values=array();
foreach($values as $key=>$value){
$inner_keys[]=$key;
$inner_values[]=$value;
}
$keyholder[]=$inner_keys;
$itemholder[]=$inner_values;
}
I think this will do it:
$cnt = count($original);
$keys = array();
$items = array();
for($i = 0; $i < $cnt; $i++) {
$keys[] = array_keys($original[$i]);
$items[] = array_values($original[$i]);
}

Array
(
[0] => Array( [0] => Array( [value] => 25 ) )
[1] => Array( [0] => Array( [value] => 75 ) )
[2] => Array( [0] => Array( [value] => 10 ) )
[3] => Array( [0] => Array( [value] => 10 ) )
)
I am working on a custom module in drupal and need to sum up the [value],
However I tried different approaches using array_column, array_sum, but didn't get the solution.
Any help would be appreciated. Thanks.
Code
$contributionDetails = $node->get('field_contributions')->getValue();
foreach ( $contributionDetails as $element ) {
$p = Paragraph::load( $element['target_id'] );
$text[] = $p->field_contribution_percentage->getValue();
}
You could make use of array_map here instead of an accumulator:
$arraySum = array_map(function ($v) {
return reset($v)['value'];
}, $text);
print_r(array_sum($arraySum)); // 120
Edit, as a full example:
$values = [
[['value' => 25]],
[['value' => 75]],
[['value' => 10]],
[['value' => 10]],
];
echo array_sum(array_map(function ($v) {
return reset($v)['value'];
}, $values)); // 120
A couple of loops and an accumulator is one way to achieve this
$tot = 0;
foreach ($array as $a){
foreach ($a as $b){
$tot += $b['value'];
}
}
echo $tot;
Or if you are sure there will always only be one occurance of the inner array.
$tot = 0;
foreach ($array as $a){
$tot += $a[0]['value'];
}
echo $tot;
Or using the code you just posted
$contributionDetails = $node->get('field_contributions')->getValue();
$tot = 0;
foreach ( $contributionDetails as $element ) {
$p = Paragraph::load( $element['target_id'] );
$text[] = $p->field_contribution_percentage->getValue();
$tot += $p->field_contribution_percentage->getValue();
}
echo $tot;
So you have an array containing 2 arrays which have the index 'value', you just need to loop each array using nested foreach and a variable $sum which sum up the value on each iteration.
Try this code:
<?php
$sum = 0;
foreach($array as $value) {
foreach ($value as $v){
$sum += $v['value'];
}
}
echo $sum;
This will output 120
I have an array that looks something like this:
Array (
[0] => Array ( [country_percentage] => 5 %North America )
[1] => Array ( [country_percentage] => 0 %Latin America )
)
I want only numeric values from above array. I want my final array like this
Array (
[0] => Array ( [country_percentage] => 5)
[1] => Array ( [country_percentage] => 0)
)
How I achieve this using PHP?? Thanks in advance...
When the number is in first position you can int cast it like so:
$newArray = [];
foreach($array => $value) {
$newArray[] = (int)$value;
}
I guess you can loop the 2 dimensional array and use a preg_replace, i.e.:
for($i=0; $i < count($arrays); $i++){
$arrays[$i]['country_percentage'] = preg_replace( '/[^\d]/', '', $arrays[$i]['country_percentage'] );
}
Ideone Demo
Update Based on your comment:
for($i=0; $i < count($arrays); $i++){
if( preg_match( '/North America/', $arrays[$i]['country_percentage'] )){
echo preg_replace( '/[^\d]/', '', $arrays[$i]['country_percentage'] );
}
}
Try this:
$arr = array(array('country_percentage' => '5 %North America'),array("country_percentage"=>"0 %Latin America"));
$result = array();
foreach($arr as $array) {
$int = filter_var($array['country_percentage'], FILTER_SANITIZE_NUMBER_INT);
$result[] = array('country_percentage' => $int);
}
Try this one:-
$arr =[['country_percentage' => '5 %North America'],
['country_percentage' => '0 %Latin America']];
$res = [];
foreach ($arr as $key => $val) {
$res[]['country_percentage'] = (int)$val['country_percentage'];
}
echo '<pre>'; print_r($res);
output:-
Array
(
[0] => Array
(
[country_percentage] => 5
)
[1] => Array
(
[country_percentage] => 0
)
)
You can use array_walk_recursive to do away with the loop,
passing the first parameter of the callback as a reference to modify the initial array value.
Then just apply either filter_var or intval as already mentioned the other answers.
$array = [
["country_percentage" => "5 %North America"],
["country_percentage" => "0 %Latin America"]
];
array_walk_recursive($array, function(&$value,$key){
$value = filter_var($value,FILTER_SANITIZE_NUMBER_INT);
// or
$value = intval($value);
});
print_r($array);
Will output
Array
(
[0] => Array
(
[country_percentage] => 5
)
[1] => Array
(
[country_percentage] => 0
)
)
You could get all nemeric values by looping through the array. However I don't think this is the most efficient and good looking answer, I'll post it anyways.
// Array to hold just the numbers
$newArray = array();
// Loop through array
foreach ($array as $key => $value) {
// Check if the value is numeric
if (is_numeric($value)) {
$newArray[$key] = $value;
}
}
I missunderstood your question.
$newArray = array();
foreach ($array as $key => $value) {
foreach ($value as $subkey => $subvalue) {
$subvalue = trim(current(explode('%', $subvalue)));
$newArray[$key] = array($subkey => $subvalue);
}
}
If you want all but numeric values :
$array[] = array("country_percentage"=>"5 %North America");
$array[] = array("country_percentage"=>"3 %Latin America");
$newArray = [];
foreach ($array as $arr){
foreach($arr as $key1=>$arr1) {
$newArray[][$key1] = intval($arr1);
}
}
echo "<pre>";
print_R($newArray);
This is kind of a ghetto method to doing it cause I love using not as many pre made functions as possible. But this should work for you :D
$array = array('jack', 2, 5, 'gday!');
$new = array();
foreach ($array as $item) {
// IF Is numeric (each item from the array) will insert into new array called $new.
if (is_numeric($item)) { array_push($new, $item); }
}
I want to delete an index from array and insert it into in new array. I want two things which i tried to explain one is
Array
(
[index1] => Deleted
[index4] => Inserted
)
Array
(
[index3] => test
[index4] => Inserted
)
Array
(
[index2] => numbers
[index3] => test
[index4] => Inserted
)
Array
(
[index1] => Deleted
)
now i want if arraysize is 1
foreach($array as $arrays){
array_push($array1,($arrays[0]));
unset ($arrays[0]);
}
i want to remove
Array
(
[index1] => Deleted
)
from $array and $array to be
[index1] => Deleted
second is if $array is
Array
(
[index2_123] => numbers
[index3_level] => test
[index4_test] => Inserted
)
i want a new array with $array1 as
Array
(
[index3_level] => test
)
and $array1 is modified to
Array
(
[index2_123] => numbers
[index4_test] => Inserted
)
Try this way,
$arr = Array
(
'index1' => 'Deleted',
'index2' => 'numbers',
'index3' => 'test',
'index4' => 'Inserted'
);
$arr1 = $arr2 = array();
$i = 0;
foreach($arr as $key => $value){
if($i%2 == 0){
$arr1[$key] = $value;
}else{
$arr2[$key] = $value;
}
$i++;
}
Output
$arr1
Array
(
[index1] => Deleted
[index3] => test
)
$arr2
Array
(
[index2] => numbers
[index4] => Inserted
)
And if you don't need that value then you can use it as
$i = 0;
foreach($arr as $key => $value){
if($i%2 == 0){
$arr[$key] = $value;
}else{
unset($arr[$key]);
}
$i++;
}
print_r($arr);
Output:
Array
(
[index1] => Deleted
[index3] => test
)
Loop through them and generate the array -
$new = array();
foreach($yourarray as $key => $val) {
$index = str_replace('index', '', $key); // get the key index
if($index % 2 != 0) { // check for odd or even
$new[$key] = $val; // set the new array
unset($yourarray[$key]); // delete from the main array
}
}
Update
For any index use a counter
$i = 0;
$new = array();
foreach($yourarray as $key => $val) {
if($i % 2 != 0) { // check for odd or even
$new[$key] = $val; // set the new array
unset($yourarray[$key]); // delete from the main array
}
$i++;
}
You can use a combination of array_flip and array_diff_key to filter the first array, then use array_diff filter the second:
$specificIndex = array('index1', 'index3');
$array1 = array_diff_key($array, array_flip($specificIndex));
$array2 = array_diff($array, $array1);
Demo.
If you want get in an array only certain elements of your choice you can do something like:
$specificIndex = array('index1', 'index3');
$selectedItem = array_intersect_key($array, array_flip($specificIndex));
Demo.
<?php
$array = array(
'index1' => 'Deleted',
'index2' => 'numbers',
'index3' => 'test',
'index4' => 'Inserted',
);
$specificIndex = 'index3';
$array1=array();
foreach($array as $key => $value){
if($key==$specificIndex){
$array1[$key] = $value;
unset($array[$specificIndex]);
}
}
print_r($array);
print_r($array1);

I have array 1 and it should be 2
Does anyone have an idea / solution?
Do i need foreach or for loop?
1.
Array
(
[0] => Array
(
[category_id] => 5
[category] => Pages
)
)
Must be:
Array
(
[0] => Array
(
[5] => Pages
)
)
I have this but this doent work...
for($x = 0; $x <= $counter; $x++){
foreach ($Categories[$x] as $key => $value){
echo $key.' '. $value.'<br>';
}
$test[$x]['category_id'] .= $Categories[$x]['category'];
}
Thanks for all the help!
Code:
<?php
$arr = array(
array(
'category_id' => 5 ,
'category' => 'Pages',
),
);
$new = array();
foreach ($arr as $item) {
$new[] = array(
$item['category_id'] => $item['category']
);
}
print_r($new);
Result:
Array
(
[0] => Array
(
[5] => Pages
)
)
$output=array();
foreach($array as $k=>$v)
{
$output[$v['category_id']]=$v['category'];
}
echo "<pre />";
print_r($output);
Demo1
Demo 2
for multidimensinal result :
$output=array();
foreach($array as $k=>$v)
{
$output[][$v['category_id']]=$v['category'];
}
echo "<pre />";
print_r($output);
As you said you will need a foreach loop to manupulate you array.
Example
$array = array
(
'0' => array
(
'category_id' => '5',
'category' => 'Pages'
)
);
$new_array = array();
foreach($array as $val)
{
$new_array[$val['category_id']] = $val['category'];
}
var_dump($new_array);
this will output
array(1) { [5]=> string(5) "Pages" }
I am having this array :
array(
0 => array("name", "address", "city"),
1=> array( "anoop", "palasis", "Indore"),
2=> array( "ravinder", "annapurna", "Indore")
)
and i want to make this array in this way :
array(
0 => array("name" = >"anoop" , "address" = >"palasia", "city" = >"Indore"),
1 => array("name" = >"ravinder" , "address" = >"annapurna", "city" = >"Indore")
)
The modern way is:
$data = array_column($data, 'value', 'key');
In your case:
$data = array_column($data, 1, 0);
Use array_combine. If $array contains your data
$result = array(
array_combine($array[0], $array[1]),
array_combine($array[0], $array[2])
);
In general
$result = array();
$len = count($array);
for($i=1;$i<$len; $i++){
$result[] = array_combine($array[0], $array[$i]);
}
If your data are in $array:
$res = array();
foreach ($array as $key=>$value) {
if ($key == 0) {
continue;
}
for ($i = 0; $i < count($array[0]); $i++) {
$res[$array[0][$i]] = $value[$i];
}
}
The result is now in $res.
Here is a function that you can use:
function rewrap(Array $input){
$key_names = array_shift($input);
$output = Array();
foreach($input as $index => $inner_array){
$output[] = array_combine($key_names,$inner_array);
}
return $output;
}
Here is a demonstration:
// Include the function from above here
$start = array(
0 => array("name", "address", "city"),
1 => array("anoop", "palasis", "Indore"),
2 => array("ravinder", "annapurna", "Indore")
);
print_r(rewrap($start));
This outputs:
Array
(
[0] => Array
(
[name] => anoop
[address] => palasis
[city] => Indore
)
[1] => Array
(
[name] => ravinder
[address] => annapurna
[city] => Indore
)
)
Note: Your first array defined index 1 twice, so I changed the second one to 2, like this:
array(0 => array("name", "address", "city"), 1 => array("anoop", "palasis", "Indore"),2 => array("ravinder", "annapurna", "Indore"))
That was probably just a typo.
