Array value and index migration - php

My array is like:
Array
(
[0] => Array
(
[0] => "name"
[1] => "zxczxc5"
)
[1] => Array
(
[0] => "about"
[1] => "zxczxc"
)
[2] => Array
(
[0] => "contact"
[1] => "zxczxc"
)
)
I want to generate another array like this :
Array
{
['name']="zxczxc5";
}
Array
{
['contact']="zxczxc";
}
Array
{
['about']="zxczxc";
}
I want the first array index zero value goes as the index of second value in my new array.
Thanks.

There are many ways to solve what you want to achieve, this is just one of those:
foreach ($array as &$pair) {
$pair = call_user_func_array('array_combine', $pair);
}
unset($pair);
print_r($array);
It makes use of array_combine.

Assuming you name your first Array $aTest:
foreach($aTest as $aElement)
{
$aNewArray[$aElement[0]] = $aElement[1];
}
print_r($aNewArray);

foreach ($array as $value) {
$newArray[$value['0']] = $value['1'];
}

Assuming the first array is called $array
$new_array = array();
foreach($array as $element)
{
$new_array[] = array($element[0] => $element[1]);
}

$newArr = array();
foreach($arr as $val) {
$newArr[$val[0]] = $val[1];
}

How can I compare two Arrays and detect if the values are incorrect or missing?

I have to arrays I would like to compare:
$original and $duplicate.
for example here is my original file:
print_r($original);
Array ( [0] => cat423 [1] => dog456 [2] => horse872 [3] => duck082 )
and here is my duplicate:
print_r($dublicate);
Array ( [0] => cat423 [1] => dug356 )
I compare them with array_diff:
$result = array_diff($original, $dublicate);
My result:
Array ( [1] => dog456 [2] => horse872 [3] => duck082 )
So far so good, but I need to make a difference between the values which are incorrect and the values which are completely missing. Is this possible?
A way would be to crawl the entire original array, afterwards you will have two arrays, missings and duplicates.
$original = array("cat423", "dog456", "horse872", "duck082");
$duplicate = array("cat423", "dug356");
$missings = $duplicates = array();
foreach ($original as $val) {
if (in_array($val, $duplicate))
$duplicates[] = $val;
else
$missings[] = $val;
}
If you need the keys as well, you would have to alter the foreach loop like so:
foreach ($original as $key=>$val) {
if (in_array($val, $duplicate))
$duplicates[] = array("key" => $key, "value" => $val);
else
$missings[] = array("key" => $key, "value" => $val);
}
use in_array function
$original = array("cat423", "dog456", "horse872", "duck082");
$duplicate = array("cat423", "dug356");
foreach ($original as $item) {
if(in_array($item, $duplicate))
{
$dup[] = $item;
}
else
{
$miss[] = $item;
}
}
print_r($miss); #Array ( [0] => dog456 [1] => horse872 [2] => duck082 )
print_r($dup); #Array ( [0] => cat423 )

Convert multidimentional array to a simple array

When print_r($my_array);
Array
(
[0] => Array
(
[value] => num1
[label] =>
)
[1] => Array
(
[value] => num2
[label] =>
)
[2] => Array
(
[value] => num3
[label] =>
)
)
Now I wonder how to create a new array variable to hold only 1 level with the following structure. e.g:
if print_r($new_array), it will show:
Array
(
[0] => num1
[1] => num2
[2] => num3
)
Try foreach() and store value in new array
foreach($arr as $v) {
$newarr[] = $v['value'];
}
print_r($newarr);
$new = array_map(function($element){ return $element['value'] ; }, $array);
Try with foreach of $my_array and assign value to $new_array variable like
$new_array = array();
foreach($my_array as $array){
$new_array[] = $array['value'];
}
print_r($new_array);
Loop thru the array as follows and push the desired elements into a new array.
$new_array = array();
for($i=0;$i<count($my_array);$i++) {
array_push($new_array, $my_array[$i]['value']);
}
print_r($new_array);
below can work:
foreach($my_array as $k => $v){
$new_array[] = $v['value'];
}
print_r($new_array);
$new_array = array();
foreach ($my_array as $key => $value) {
$new_array[] = $value['value'];
}
print_r($new_array);

Replace key of array with the value of another array while looping through

I have two multidimensional arrays. First one $properties contains english names and their values. My second array contains the translations. An example
$properties[] = array(array("Floor"=>"5qm"));
$properties[] = array(array("Height"=>"10m"));
$translations[] = array(array("Floor"=>"Boden"));
$translations[] = array(array("Height"=>"Höhe"));
(They are multidimensional because the contains more elements, but they shouldn't matter now)
Now I want to translate this Array, so that I its at the end like this:
$properties[] = array(array("Boden"=>"5qm"));
$properties[] = array(array("Höhe"=>"10m"));
I have managed to build the foreach construct to loop through these arrays, but at the end it is not translated, the problem is, how I tell the array to replace the key with the value.
What I have done is this:
//Translate Array
foreach ($properties as $PropertyArray) {
//need second foreach because multidimensional array
foreach ($PropertyArray as $P_KiviPropertyNameKey => $P_PropertyValue) {
foreach ($translations as $TranslationArray) {
//same as above
foreach ($TranslationArray as $T_KiviTranslationPropertyKey => $T_KiviTranslationValue) {
if ($P_KiviPropertyNameKey == $T_KiviTranslationPropertyKey) {
//Name found, save new array key
$P_KiviPropertyNameKey = $T_KiviTranslationValue;
}
}
}
}
}
The problem is with the line where to save the new key:
$P_KiviPropertyNameKey = $T_KiviTranslationValue;
I know this part is executed correctly and contains the correct variables, but I believe this is the false way to assing the new key.
This is the way it should be done:
$properties[$oldkey] = $translations[$newkey];
So I tried this one:
$PropertyArray[$P_KiviPropertyNameKey] = $TranslationArray[$T_KiviTranslationPropertyKey];
As far as I understood, the above line should change the P_KiviPropertyNameKey of the PropertyArray into the value of Translation Array but I do not receive any error nor is the name translated. How should this be done correctly?
Thank you for any help!

)
[3] => Array

I can build the translations array in another way. I did this like this, because in the second step I have to check, which group the keys belong to...
Try this :
$properties = array();
$translations = array();
$properties[] = array("Floor"=>"5qm");
$properties[] = array("Height"=>"10m");
$translations[] = array("Floor"=>"Boden");
$translations[] = array("Height"=>"Höhe");
$temp = call_user_func_array('array_merge_recursive', $translations);
$result = array();
foreach($properties as $key=>$val){
foreach($val as $k=>$v){
$result[$key][$temp[$k]] = $v;
}
}
echo "<pre>";
print_r($result);
output:
Array
(
[0] => Array
(
[Boden] => 5qm
)
[1] => Array
(
[Höhe] => 10m
)
)
Please note : I changed the array to $properties[] = array("Floor"=>"5qm");, Removed a level of array, I guess this is how you need to structure your array.
According to the structure of $properties and $translations, you somehow know how these are connected. It's a bit vague how the indices of the array match eachother, meaning the values in $properties at index 0 is the equivalent for the translation in $translations at index 0.
I'm just wondering why the $translations array need to have the same structure (in nesting) as the $properties array. To my opinion the word Height can only mean Höhe in German. Representing it as an array would suggest there are multiple translations possible.
So if you could narrow down the $translations array to an one dimensional array as in:
$translation = array(
"Height"=>"Höhe",
"Floor"=>"Boden"
);
A possible loop would be
$result = array();
foreach($properties as $i => $array2) {
foreach($array2 as $i2 => $array3) {
foreach($array3 as $key => $value) {
$translatedKey = array_key_exists($key, $translations) ?
$translations[$key]:
$key;
$result[$i][$i2][$translatedKey] = $value;
}
}
}
(I see every body posting 2 loops, it's an array,array,array structure, not array,array ..)
If you cannot narrow down the translation array to a one dimensional array, then I'm just wondering if each index in the $properties array matches the same index in the $translations array, if so it's the same trick by adding the indices (location):
$translatedKey = $translations[$i][$i2][$key];
I've used array_key_exists because I'm not sure a translation key is always present. You have to create the logic for each case scenario yourself on what to check or not.
This is a fully recursive way to do it.
/* input */
$properties[] = array(array("Floor"=>"5qm", array("Test"=>"123")));
$properties[] = array(array("Height"=>"10m"));
$translations[] = array(array("Floor"=>"Boden", array("Test"=>"Foo")));
$translations[] = array(array("Height"=>"Höhe"));
function array_flip_recursive($arr) {
foreach ($arr as $key => $val) {
if (is_array($val)) {
$arr[$key] = array_flip_recursive($val);
}
else {
$arr = #array_flip($arr);
}
}
return $arr;
}
function array_merge_it($arr) {
foreach ($arr as $key => $val) {
if (is_array($val)) {
$arr[$key] = array_merge_it($val);
} else {
if(isset($arr[$key]) && !empty($arr[$key])) {
#$arr[$key] = $arr[$val];
}
}
}
return $arr;
}
function array_delete_empty($arr) {
foreach ($arr as $key => $val) {
if (is_array($val)) {
$arr[$key] = array_delete_empty($val);
}
else {
if(empty($arr[$key])) {
unset($arr[$key]);
}
}
}
return $arr;
}
$arr = array_replace_recursive($properties, $translations);
$arr = array_flip_recursive($arr);
$arr = array_replace_recursive($arr, $properties);
$arr = array_merge_it($arr);
$arr = array_delete_empty($arr);
print_r($arr);

You have to do the for loop in this way. If i understood you right (i.e) in associative array first key is same (some index).
foreach($properties as $key => $values) {
foreach($values as $key1 => $value1) {
$propertyResult[] = array($translations[$key][$key1][$value1] => $properties[$key][$key1][$value1]);
}
}
print_r($propertyResult);

PHP Array output from result array values

Below is my result array:
Array
(
[0] => Array
(
[id] => 3
[name] => test
)
[1] => Array
(
[id] => 4
[name] => Balikavadhu
)
)
From above array, I want to generate a new array as below:
array(3,4) // where 3 and 4 are id values of respective array
Any help or quick answer will be appreciated.
Thanks in advance !
Yet another option:
$newArray = [];
foreach ($arrayResults as $result) {
$newArray[] = $result['id'];
}
Put your output array into an array called $arr. Then do this :
$newArr = array();
$id = 0;
foreach ($arr as $val)
{
$newArr[$i] = $val['id'];
$id++;
}
You could do something like
$newArray = [];
foreach ($arrayResults as $result) {
array_push($newArray, $result['id']);
}

Explode multiple comma-separated strings in a 2d array, then get all unique values

I have an 2d array which returns me this values:
Array (
[0] => Array (
[0] => wallet,pen
[1] => perfume,pen
)
[1] => Array (
[0] => perfume, charger
[1] => pen,book
).
Out of this i would like to know if it is possible to create a function which would combine the array going this way,and create a new one :
if for example [0] => Array ( [0] => wallet,pen [1] => perfume,pen ) then should be equal to
[0] => Array ( [0] => wallet,pen, perfume ) because there is a common word else do nothing.
And also after that retrieve each words as strings for further operations.
How can i make the values of such an array unique. Array ( [0] => Array ( [0] => wallet [1] => pen [2] => perfume [3] => pen) ) as there is pen twice i would like it to be deleted in this way ( [0] => Array ( [0] => wallet [1] => pen [2] => perfume) )
It's just a matter of mapping the array and combining the inner arrays:
$x = [['wallet,pen', 'perfume,pen'], ['perfume,charger', 'pen,book']];
$r = array_map(function($item) {
return array_unique(call_user_func_array('array_merge', array_map(function($subitem) {
return explode(',', $subitem);
}, $item)));
}, $x);
Demo
This first splits all the strings based on comma. They are then merged together with array_merge() and the duplicates are removed using array_unique().
See also: call_user_func_array(), array_map()
Try this :
$array = Array (Array ( "wallet,pen", "perfume,pen" ), Array ( "perfume, charger", "pen,book" ));
$res = array();
foreach($array as $key=>$val){
$temp = array();
foreach($val as $k=>$v){
foreach(explode(",",$v) as $vl){
$temp[] = $vl;
}
}
if(count(array_unique($temp)) < count($temp)){
$res[$key] = implode(",",array_unique($temp));
}
else{
$res[$key] = $val;
}
}
echo "<pre>";
print_r($res);
output :
Array
(
[0] => wallet,pen,perfume
[1] => Array
(
[0] => perfume, charger
[1] => pen,book
)
)
You can eliminate duplicate values while pushing them into your result array by assigning the tag as the key to the element -- PHP will not allow duplicate keys on the same level of an array, so any re-encountered tags will simply be overwritten.
You can use recursion or statically written loops for this task.
Code: (Demo)
$result = [];
foreach ($array as $row) {
foreach ($row as $tags) {
foreach (explode(',', $tags) as $tag) {
$result[$tag] = $tag;
}
}
}
var_export(array_values($result));
Code: (Demo)
$result = [];
array_walk_recursive(
$array,
function($v) use(&$result) {
foreach (explode(',', $v) as $tag) {
$result[$tag] = $tag;
}
}
);
var_export(array_values($result));
