I'm trying to get an xml file from an associative array having array keys encapsuled into '<' and '>'
I've tried to use a recursive function but it works correctly only on the first level:
Please remember my final goal is to create an xml, so any appropriate suggest is welcome
this is what I've done so far:
$arr =
array('<Lev0_0>' => 0,
'<Lev0_1>' => 1,
'<Lev0_2>' => array (
'<Lev1_0>' => 2,
'<Lev1_1>' => 3
)
);
print_r(RepairKeysMultidimensional($arr));
function RepairKeysMultidimensional(array $array){
$Keys = array();
foreach($array as $Key => $Value){
$NewKey = str_replace(array('<','>'),'',$Key);
$array[$NewKey] = $Value;
unset($array[$Key]);
if(is_array($Value)){
RepairKeysMultidimensional($Value);
}
}
return $array;
}
the output is:
Array (
[Lev0_0] => 0
[Lev0_1] => 1
[Lev0_2] => Array (
[] => 2
[] => 3
)
)
If that's the structure and you never expect < or > as part of the values, you don't need to loop over it just json_encode it, strip out the chars and the json_decode it back into an array.
<?php
$arr = array(
'<Lev0_0>' => 0,
'<Lev0_1>' => 1,
'<Lev0_2>' => array (
'<Lev1_0>' => 2,
'<Lev1_1>' => 3
)
);
$arr = json_decode(str_replace(array('<','>'), '', json_encode($arr)), true);
print_r($arr);
https://3v4l.org/2d7Hq
Result:
Array
(
[Lev0_0] => 0
[Lev0_1] => 1
[Lev0_2] => Array
(
[Lev1_0] => 2
[Lev1_1] => 3
)
)
Try to add affectation in your if statement:
function RepairKeysMultidimensional(array $array){
$Keys = array();
foreach($array as $Key => $Value){
$NewKey = str_replace(array('<','>'),'',$Key);
$array[$NewKey] = $Value;
unset($array[$Key]);
if (is_array($Value)) {
$array[$NewKey] = RepairKeysMultidimensional($Value);
}
}
return $array;
}
you are not affecting the result of the second call to the outer array!
Try this :
<?php
$arr =
array('<Lev0_0>' => 0,
'<Lev0_1>' => 1,
'<Lev0_2>' => array (
'<Lev1_0>' => 2,
'<Lev1_1>' => 3
)
);
echo str_replace(array('<','>'),'','<Lev0>');
echo '<br/><br/>';
print_r(RepairKeysMultidimensional($arr));
function RepairKeysMultidimensional(array $array){
$Keys = array();
foreach($array as $Key => $Value){
$NewKey = str_replace(array('<','>'),'',$Key);
unset($array[$Key]);
if(is_array($Value)){
$array[$NewKey] = RepairKeysMultidimensional($Value);
}else{
$array[$NewKey] = $Value;
}
}
return $array;
}
The output of this is :
Array (
[Lev0_0] => 0
[Lev0_1] => 1
[Lev0_2] => Array (
[Lev1_0] => 2
[Lev1_1] => 3 ) )
After implementing database queries, I am getting the multi-dimensional array below.
Two Dimensional Array
Array
(
[0] => Array
(
[t1] => test1
)
[1] => Array
(
[t2] => test2
)
[2] => Array
(
[t3] => test3
)
[3] => Array
(
[t4] => test4
)
[4] => Array
(
[t5] => test5
)
)
but I want to convert it to a single dimensional array, like the format below:
One Dimensional Array
Array (
t1 => test1
t2 => test2
t3 => test3
t4 => test4
t5 => test5
)
How can I do this?
I think you can use array_reduce() function.
For example:
$multi= array(0 => array('t1' => 'test1'),1 => array('t2' => 'test2'),2 => array('t3' => 'test3'),3 => array('t4' => 'test4'));
$single= array_reduce($multi, 'array_merge', array());
print_r($single); //Outputs the reduced aray
You can use as follows :
$newArray = array();
foreach($arrayData as $key => $value) {
foreach($value as $key2 => $value2) {
$newArray[$key2] = $value2;
}
}
Where $arrayData is your DB data array and $newArray will be the result.
Assuming that source array is array of arrays and it has no the same keys:
<?php
$src = [
['t1'=>'test1'],
['t2'=>'test2'],
['t3'=>'test3'],
['t4'=>'test4'],
['t5'=>'test5'],
];
$result = call_user_func_array('array_merge', $src);
result via var_dump():
array(5) {
["t1"]=>
string(5) "test1"
["t2"]=>
string(5) "test2"
["t3"]=>
string(5) "test3"
["t4"]=>
string(5) "test4"
["t5"]=>
string(5) "test5"
}
You can use array_reduce() to change values of array. In callback get key of item using key() and select first item using reset().
$newArr = array_reduce($oldArr, function($carry, $item){
$carry[key($item)] = reset($item);
return $carry;
});
Check result in demo
Try this function,
function custom_function($input_array)
{
$output_array = array();
for ($i = 0; $i < count($input_array); $i++) {
for ($j = 0; $j < count($input_array[$i]); $j++) {
$output_array[key($input_array[$i])] = $input_array[$i][key($input_array[$i])];
}
}
return $output_array;
}
$arr = custom_function($arr);
print_r($arr);
Give it a try, it will work.
You can use this
<?php
$temp = array(array('t1' => 'test1'), array('t2' => 'test2'), array('t3' => 'test3'), array('t4' => 'test4'), array('t5' => 'test5'));
$result_array = array();
foreach ($temp as $val) {
foreach ($val as $key => $inner_val) {
$result_array[$key] = $inner_val;
}
}
print_r($result_array);
?>
// Multidimensional array
$arrdata = Array(
'0' => Array(
't1' => 'test1'
) ,
'1' => Array(
't2' => 'test2'
) ,
'2' => Array(
't3' => 'test3'
)
);
// Convert to a single array
$data = array();
foreach($arrdata as $key => $value) {
foreach($value as $key1 => $value1) {
$data[$key1] = $value1;
}
}
echo $data;
Try array map function.
$singleDimensionArray = array_map('current',$multiDimensionArray);
You can use this if you don't care about keeping the correct array keys
function flattenA(array $array) {
$return = array();
array_walk_recursive($array, function($a) use (&$return) { $return[] = $a; });
return $return;
}
print_r(flattenA($arr));
// Output
Array
(
[0] => test1
[1] => test2
[2] => test3
[3] => test4
[4] => test5
)
Otherwise
function flattenB(array $array) {
$return = array();
array_walk_recursive($array, function($v,$k) use (&$return) { $return[$k] = $v; });
return $return;
}
print_r(flattenB($arr));
// Output
Array
(
[t1] => test1
[t2] => test2
[t3] => test3
[t4] => test4
[t5] => test5
)

For your specific case, I would use array_reduce where I set the initial value with an empty array
array_reduce($arr, function($last, $row) {
return $last + $row;
}, array());
AFTER PHP 7.4
array_reduce($arr, fn ($last, $row) => $last + $row, []);
Result :
[
't1' => 'test1',
't2' => 'test2',
't3' => 'test3',
't4' => 'test4',
't5' => 'test5'
]
Hey #Karan Adhikari Simple like below one:
<?php
$arr1 = array(array("t1" => "test1"), array("t2" => "test2"), array("t3" => "test3"), array("t4" => "test4"), array("t5" => "test5"));
echo "<pre>";
print_r($arr1);//before
$arr2 = array();
foreach($arr1 as $val){
$arr2 = array_merge($arr2, $val);
}
echo "<pre>";
print_r($arr2); // after you get your answer
Please try this function:
function array_merging($multi_array) {
if (is_array($multi_array)) {
$new_arr = array();
foreach ($multi_array as $key => $value) {
if (is_array($value)) {
$new_arr = array_merge($new_arr, array_merging($value));
}
else {
$new_arr[$key] = $value;
}
}
return $new_arr;
}
else {
return false;
}
}
Use this function:
$your_multi_arr = array(array(array('t1'=>'test1'),array('t2'=>'test2'),array('t3'=>'test3'),array('t4'=>'test4')));
$arr1 = array_merging($your_multi_arr);
echo "<pre>";
print_r($arr1);
Hope, this may be useful for you.
You can try traversing the array using PHP while list and each. I took sample code from PHP website the second example you can check it here
$arr = [['t1' => 'test1'],['t2' => 'test2'],['t3' => 'test3'],['t4' => 'test4'],['t5' => 'test5']];
$output = [];
while (list($key, $val) = each($arr)) {
while (list($k, $v) = each($val)) {
$output[$k] = $v;
}
}
print_r($output);
Output created is
Array
(
[t1] => test1
[t2] => test2
[t3] => test3
[t4] => test4
[t5] => test5
)
You can test it on your own in this Sandbox example.
This will do the trick
$array = array_column($array, 't1');
Note: This function array_column introduced in PHP 5.5 so it won't work in earlier versions.
traverse the array and save the key value, Live Demo here.
<?php
$array = array(array('t1' => 'test1'), array('t2' => 'test2'), array('t3' => 'test3'), array('t4' => 'test4'), array('t5' => 'test5'));
$result = [];
array_walk($array, function($value) use(&$result){
foreach($value as $k => $v)
{
$result[$k] = $v;
}
});
var_dump($result);
`$result = "Query"; $key_value = array();`
foreach ($result as $key => $value) {
$key_value[$key['']] = $value[''];
}
//for checking //echo "<pre>" ; print_r($key_value) ; exit;
return $key_value;
pls fill $key['name given in sql query for field'] and $value['name given in sql query for field'] (both are same)
this works for me
$result = [];
foreach($excelEmails as $arr)
{
foreach ($arr as $item){
$result = array_merge($result , $item);
}
}
dd($result);
i would recomment my way to convert all double-dimensional array to single-dimensional array.
<?php
$single_Array = array();
//example array
$array = array(
array('t1' => 'test1'),
array('t2' => 'test2'),
array('t3' => 'test3'),
array('t4' => 'test4'),
array('t5' => 'test5'));
$size = sizeof($array);
//loop to fill the new single-dimensional array
for($count = 0; $count<sizeof($array);$count++)
{
//take the key of multi-dim array
$second_cell = key($array[$count]);
//set the value into the new array
$single_array[$count] = $array[$count][$second_cell];
}
//see the results
var_dump($single_array);
?>
with this script we can take keys and values to create new single-dimensional array.I hope that i was helpfull to you.
you can see the example here: Array Convert Demo
I have an array like below, as you can see the last array [adad] value is blank, how can I write an if statement to tell whether this is blank.
Array
(
[K] => Array
(
[0] => mabel__chan
[1] => mabel chan
)
[B] => Array
(
[0] => kieron br
)
[C] => Array
(
[0] => a br
[1] => a
)
[adad] => Array
(
[0] =>
)
)
I have tried doing this
if (count(array_filter($array)) == 0) {}
Pseudo code
if(array[key] == blank) {
echo "is blank";
} else {
echo "isn't blank";
}
**PHP Script this is how I get my data from mongoDB*
The answer below is working correctly when I use echos but now when I'm trying to push into new arrays its broken somewhere I get no data back anymore.
$col = "A" . $user->agencyID;
$db = $m->rules;
$collection = $db->$col;
$id = $_POST['ruleID'];
$search = array(
'_id' => new MongoId($id)
);
$cursor = $collection->find($search);
$validTagsArray = array();
$validArray = array();
foreach ($cursor as $key => $value) {
$temp = array_walk($array, function($v, $k) {
if (count(array_filter($v)) === 0) {
foreach ($value['AutoFix'] as $keyTwo => $valTwo) {
$x = 0;
$validTagsArray['data'][] = array($keyTwo, $x);
}
} else {
foreach ($value['AutoFix'] as $keyTwo => $valTwo) {
$x = 0;
foreach ($valTwo as $key => $value) {
$x++;
}
$validTagsArray['data'][] = array($keyTwo, $x);
}
}
});
}
echo json_encode($validTagsArray);
You can try this -
$array = array
(
'K' => array('0' => 'mabel__chan','1' => 'mabel chan'),
'B' => array('0' => 'kieron br'),
'C' => array('0' => 'a br', '1' => 'a'),
'adad' => array('0' => '')
);
$temp = array_walk($array, function($v, $k) {
if(count(array_filter($v)) === 0) { // check the count of non-empty elements in the sub array
echo $k . ' is empty';
}
});
Output
adad is empty
You can write as:
if([adad][0]== " ")
{
}
You can also try this :
foreach($array as $key=>$value){
if(empty($value))
echo "empty";
}
i have a problem with arrays, there are not my friends :)
i have a this array:
Array
(
[0] => 2012163115
[1] => 2012163115
[2] => 2012161817
[3] => 201214321971
[4] => 201214321971
[5] => 201214321971
)
and i need this with all the variables appear more than once
Array
(
[0] => 2012163115
[1] => 201214321971
)
i try this
foreach ($array as $val) {
if (!in_array($val, $array_temp)) {
$array_temp[] = $val;
} else {
array_push($duplis, $val);
}
}
but the result is
Array
(
[0] => 2012163115
[1] => 201214321971
[2] => 201214321971
)
where is my mistake? thanks for help!
array_unique() is there for you.
EDIT: ops I didn't notice the "more than once" clause, in that case:
$yourArray = array('a', 'a', 'b', 'c');
$occurrences = array();
array_walk($yourArray, function($item) use(&$occurrences){
$occurrences[$item]++;
});
$filtered = array();
foreach($occurrences as $key => $value){
$value > 1 && $filtered[] = $key;
}
var_dump($filtered);
$array = array(
'2012163115',
'2012163115',
'2012161817',
'201214321971',
'201214321971',
'201214321971',
);
$duplication = array_count_values($array);
$duplicates = array();
array_walk($duplication, function($key, $value) use (&$duplicates){
if ($key > 1)
$duplicates[] = $value;
});
var_dump($duplicates);
Please see http://php.net/manual/en/function.array-unique.php#81513

$array_counting = array();
foreach ($array as $val)
if ( ! in_array($val, $array_counting))
{
$array_counting[$val] ++; // counting

$array_dups = array();
foreach ($array_counting as $key => $count)
{
if ($count > 1)
$array_dups[] = $key; // this is more than once
}
If a have an array:
Array
(
[1-title1] => Array
(
[0] => title = title erer
[1] => 1-title1
[2] => content = content 1
)
[2-title2] => Array
(
[0] => title = title dffgfghfdg
[1] => 2-title2
[2] => content = content 2
)
and I want to get array:
Array
(
[1-title1] => Array
(
[title] =>title erer
[1] =>title1
[content] =>content 1
)
[2-title2] => Array
(
[title] =>title dffgfghfdg
[2] => title2
[content] =>content 2
)
What should I do?
A solution without references and no implicit key names.
foreach ($array as $key => $innerArray) {
foreach ($innerArray as $innerKey => $value) {
if (false !== strpos($value, ' = ')) {
unset($array[$key][$innerKey]);
list($innerKey, $value) = explode(' = ', $value, 2);
$array[$key][$innerKey] = $value;
}
}
}
foreach($array as &$title){
$newTitle = array();
$titleName = explode(' = ', $title[0] , 2);
$newTitle['title'] = end($titleName);
$titleNum = explode('-', $title[1] , 2);
$newTitle[$titleNum[0]] = $titleNum[1];
$titleContent = explode(' = ', $title[2] , 2);
$newTitle['content'] = end($titleContent);
$title = $newTitle;
}
try this
foreach($array as $ky=>$val) {
echo $ky;
var_dump(array_keys($val));
}
