Php array value to keys - php

Hi let's say I have this array
array(2) {
[0]=>
string(9) "name|a-z+"
[1]=>
string(7) "id|0-9+"
}
Now I want a new array (or the same if possible) to be like this:
array(2) {
[name]=>
string(4) "a-z+"
[id]=>
string(4) "0-9+"
}
I think the solution implies explode and array_combine, but I am not good enough, can someone help me?
Thanks in advance.

function convert_my_array($arr){
$out = array();
foreach($arr as $obj){
$data = explode("|", $obj);
$out[$data[0]] = $data[1];
}
return $out;
}

Using the original array called $array here, loop through it set the values to what you want.
$newarray = array();
foreach ($array as $key=>$val) {
list($one, $two) = explode('|', $val);
$newarray[$one] = $two;
}

Re-arranging and combining an array

I'm having an issue when I dump the array below. This dumps several arrays. Some are 2 some are 3, which complicates it even more. Basically what I want I put below. I have tried array_push, array_combine, array_merge, several different ways including $array[$param] = $insertValue and I'm stuck. I am open to creating a brand new array too.
Please note not all arrays are counts of 3 but always return at least 1.
Original array:
array(3) {
[0]=>
array(2) {
["contact_id"]=>
string(9) "CONTACTID"
["contact_id_content"]=>
string(19) "123456789123456"
}
[1]=>
array(2) {
["sm_owner"]=>
string(9) "SMOWNERID"
["sm_owner_content"]=>
string(19) "123456798452"
}
[2]=>
array(2) {
["contact_owner"]=>
string(13) "Contact Owner"
["contact_owner_content"]=>
string(16) "Jane Doe"
}
Array desired:
array(3) {
[0]=>
array(6) {
["contact_id"]=>
string(9) "CONTACTID"
["contact_id_content"]=>
string(19) "123456789123456"
["sm_owner"]=>
string(9) "SMOWNERID"
["sm_owner_content"]=>
string(19) "123456798452"
["contact_owner"]=>
string(13) "Contact Owner"
["contact_owner_content"]=>
string(16) "Jane Doe"
}
try this code:
$NewArray = array();
foreach($OriginalArray as $value) {
$NewArray[] = array_merge($value,$NewArray);
}
or you can use array_merge_recursive
let $result = [];
foreach ($yourarray as $key => $value) {
$result = $value;
}
var_dump($result);
Here you go: How to Flatten a Multidimensional Array? – Barmar 23 mins ago
function flatten($array)
{
return array_reduce($array, function($acc, $item){
return array_merge($acc, is_array($item) ? flatten($item) : [$item]);
}, []);
}
// loop the individual fields
for ($i=0; $i<count($row_data); $i++) {
$newArray = flatten([$i => $response_row]);
}
Try something like this:
function flatten(array $array) : array
{
$newArray = [];
foreach ($array as $subArray) {
foreach ($subArray as $key => $value) {
$newArray[$key] = $value;
}
}
return $newArray;
}

Building a multidimensional Array with another Array in PHP

I try to build an array. I don't wanna write something like $array[3][5][8] = []. Because the count of the first Array can change, here it's 3 but it also can be like 9 or 12. Also the values can change, but they are always unique numbers. I hope someone knows a better way. Thank you.
// First Array, which I have. The count and the content can change.
array(3) {
[0]=>
string(1) "3"
[1]=>
string(1) "5"
[2]=>
string(1) "8"
}
// Second Array, thats the goal.
array(1) {
[3]=>
array(1) {
[5]=>
array(1) {
[8]=>
array(0) {
}
}
}
}
This code will solve your problem:
$array = [3,5,8,9]; // your first array
$newArray = null;
foreach ($array as $value) {
if($newArray === null) {
$newArray[$value] = [];
$ref = &$newArray[$value];
}
else {
$ref[$value] = [];
$ref = &$ref[$value];
}
}
$newArray - holds the result you wanted
$array1=array(3,5,8);
$array2=array();
for($i=count($array1);$i>0;$i--){
$temp=array();
$temp[$array1[$i-1]]=$array2;
$array2=$temp;
}
$subject is the reference to the array you are currently in.
$array is the main root array that you obtain in the end.
$input is the input int array.
$subject = $array = [];
foreach($input as $key){
$subject[$key] = []; // create empty array
$subject =& $subject[$key]; // set reference to child
// Now $subject is the innermost array.
// Editing $subject will change the most nested value in $array
}

Custom array concat with the same key in PHP

I have 2 arrays
$array1[01] = "audi||opel";
$array1[02] = "bmw||ford";
and the second one
$array2[01] = "blue||yellow";
$array2[02] = "white||red";
I would like to merge the two arrays and get my array in this format:
$array_custom[01] = "audi||opel||blue||yellow";
$array_custom[02] = "bmw||ford||white||red"";
How can I do that ? Thx in advance
Use array_map:
$array_custom = array_map(function ($array1, $array2) { return "$array1||$array2"; },
$array1, $array2);
If you want to keep your indexes:
foreach ($array1 as $key => $value) {
$array_custom[$key] = "$value||{$array2[$key]}";
}
Hope the following code is what you're looking for.
$arrCount = count($array1);
for($i=0;$i<=$arrCount;$i++){
$array_custom[$i] = array_merge($array1[$i],$array2[$i]) //Or whatever your preferred way to concatenate this.
}
Try this:
$array1[01] = "audi||opel";
$array1[02] = "bmw||ford";
$array2[01] = "blue||yellow";
$array2[02] = "white||red";
$array_custom[01]=array($array1[01]."||".$array2[01]);
$array_custom[02]=array($array1[02]."||".$array2[02]);
//result will be this
array(1) { [0]=> string(24) "audi||opel||blue||yellow" }
array(1) { [0]=> string(21) "bmw||ford||white||red" }

How to create an array using array_fill function in PHP?

I want to create an array like below
array(2) {
[0]=>
array(2) {
[0]=>
int(1)
[1]=>
int(0)
}
[1]=>
array(2) {
[0]=>
int(2)
[1]=>
int(0)
}
}
Here first element of the inner array will be incremental and second element will always be 0. The outer array length should be 30. I spent a lot of of time on it but couldn't solve it by my one.
Can any one of you help me ?
Thanks
You could do it using array_map() and range():
$o = array_map(function($a) { return array($a, 0); }, range(1, 30));
Demo
The array_fill() function creates an array where all elements are identical. You're asking for an array where the elements aren't all identical, so it's not something you can create simply by using array_fill()....
$array = array_fill(0, 2, array_fill(0, 2, 0));
array_walk($array, function(&$value, $key) { $value[0] = $key+1; });
Maybe you want something like this?
<?php
function initArray() {
$array = array();
for ($i = 1; $i <= 30; $i++) {
$array[] = array($i, 0);
}
return $array;
}
// now call the initArray() function somewhere you need it
$myFancyArray = initArray();
?>

Create string to put in an IN statement from an array of arrays

I have an array of arrays that look like this:
array(40) {
[0]=>
array(2) {
["id"]=>
string(2) "ta"
["size"]=>
int(2)
[1]=>
array(2) {
["id"]=>
string(2) "tq"
["size"]=>
int(4)
....
I want to be able to get all the sizes in a way that I can do a query like this:
IN (2,4)
so... For each array, get the size key: IN (size,size,size...)
Thanks!
You could do something like this:-
$sizes = implode(',', array_map(function($v) { return $v['size']; }, $array));
Then just pass $sizes to your IN query
edit
In response to your comment below, you can use array_unique to remove duplicate sizes, eg:
$sizes = implode(',', array_unique(array_map(function($v) { return $v['size']; }, $array)));
Here you go:
$a = array("id"=>"ta","size"=>2);
$b = array("id"=>"tq","size"=>4);
$c = array($a,$b);
$in = array();
foreach ($c as $key=>$value) {
if(array_key_exists("size", $value)){
$in[] = $value["size"];
}
}
echo implode(",", $in);
$sizes = array();
foreach($array as $value) {
$sizes[] = $value['size'];
}
$query = implode(',', $sizes);
query ..." IN ($query) "..
