I have an array
Array ( [0] => 4-8-2019 [1] => 5-8-2019 [2] => 5 [3] => 6 ,[4]=>1,[5]=>2 )
How I can make this.Pleasse help me I have tried array mege but not working
Array ( [0] =>
[0]=> 4-8-2019
[1] => 5
[2] => 1
[1] =>[0]=> 5-8-2019
[1]=>6
[2]=>2 )
You want to seperate you array into two by every other item.
foreach($array as $key => $value){
$result[$key & 1][] = $value;
}
Only logic I found in your example is about even and odd indexes. If that's what you want to do, try this :
<?php
$array = [
'4-8-2019',
'5-8-2019',
'5',
'6',
'1',
'2',
];
$odds = [];
$evens = [];
foreach ($array as $index => $value) {
if ($index % 2 === 0) {
$evens[] = $value;
} else {
$odds[] = $value;
}
}
var_dump([$evens, $odds]);
Which outputs :
array(2) {
[0]=>
array(3) {
[0]=>
string(8) "4-8-2019"
[1]=>
string(1) "5"
[2]=>
string(1) "1"
}
[1]=>
array(3) {
[0]=>
string(8) "5-8-2019"
[1]=>
string(1) "6"
[2]=>
string(1) "2"
}
}

I need to store an array in this format
array(2)
{
[1002] => array(2)
{
[0] => string(1) "2"
[1] => string(1) "1"
}
}
So far i only have this:
function permissions($conn){
$sql="SELECT PROCESS,PERMISSION FROM table WHERE PROCESS=1002";
$result = $conn->executeSQL($sql);
$return = array();
foreach($result as $value){
array_push($return,$value['PROCESS_ID'],$value['PERMISSION_ID']);
}
which brings:
I don´t know how to make this array multidimensional, i don't want the "1002" to repeat
array(2)
{
[0] => string(4) "1002"
[1] => string(1) "2"
[2] => string(4) "1002"
[3] => string(1) "1"
}
Hi try something like this:
function permissions($conn){
$sql="SELECT PROCESS,PERMISSION FROM table WHERE PROCESS=1002";
$result = $conn->executeSQL($sql);
$return = array();
foreach($result as $value){
if(!isset($return[$value['PROCESS_ID']])){
$return[$value['PROCESS_ID']] = [];
}
$return[$value['PROCESS_ID']][] = $value['PERMISSION_ID'];
}
I need to count the same values in multidimensional array and remove the duplicates.
My array:
$r = [
['a','b'],
['a','b'],
['c','d'],
['c','d'],
['c','d'],
['e','f'],
];
Need to output:
[0] => Array
(
[0] => a
[1] => b
[1] => 2 // Result
)
[1] => Array
(
[0] => c
[1] => d
[1] => 3 // Result
)
[2] => Array
(
[0] => e
[1] => f
[1] => 1 // Result
)
I will be very grateful for your help.
<?php
$r = [
['a','b'],
['a','b'],
['c','d'],
['c','d'],
['c','d'],
['e','f'],
];
foreach($r as $arr)
{
$o[implode(',', $arr)][] = 1;
}
$output = [];
array_walk($o, function($v, $k) use(&$output){
$output[] = array_merge(explode(',', $k), [count($v)]);
});
var_dump($output);
and the output:
array(3) {
[0]=>
array(3) {
[0]=>
string(1) "a"
[1]=>
string(1) "b"
[2]=>
int(2)
}
[1]=>
array(3) {
[0]=>
string(1) "c"
[1]=>
string(1) "d"
[2]=>
int(3)
}
[2]=>
array(3) {
[0]=>
string(1) "e"
[1]=>
string(1) "f"
[2]=>
int(1)
}
}
foreach ( $result1 as $key ):
$o[implode(', ', $key)][] = null;
foreach ($o as $key1) {
$g[implode(', ', $key)] = count($key1);
}
endforeach;
print_r($g);
Having the following array:
array(4) {
[0]=>
array(2) {
[0]=>
string(3) "233"
[1]=>
string(37) "some data"
}
[1]=>
array(2) {
[0]=>
string(3) "233"
[1]=>
string(68) "some other data"
}
[2]=>
array(2) {
[0]=>
string(3) "144"
[1]=>
string(38) "some other data"
}
[3]=>
array(2) {
[0]=>
string(3) "233"
[1]=>
string(42) "some other data"
}
}
I want to replace the values 233 and 144 (the key 0 from the inner array) by some random HEX color. The ones with the same keys (233) for example, has to have the same HEX color (FFF000 for example in the desired solution above).
This is the function I use to generate random HEX colors:
function randHEXcolor() {
return sprintf('%06X', mt_rand(0, 0xFFFFFF));
}
My desired output should be:
array(4) {
[0]=>
array(2) {
[0]=>
string(6) "FFF000"
[1]=>
string(37) "some data"
}
[1]=>
array(2) {
[0]=>
string(6) "FFF000"
[1]=>
string(68) "some other data"
}
[2]=>
array(2) {
[0]=>
string(6) "111333"
[1]=>
string(38) "some other data"
}
[3]=>
array(2) {
[0]=>
string(6) "FFF000"
[1]=>
string(42) "some other data"
}
}
How can I archieve this?
Thanks in advance.
foreach ($array as &$item) {
if (!isset($temp[$item[0]]) {
$temp[$item[0]] = randHEXcolor();
}
$item[0] = $temp[$item[0]];
}
If you want all values to be translated to the same random color, you'll have to save those colors:
$colors_translation = array();
foreach ($array as &$item) {
$color = $item[ 0 ];
$translate = $colors_translation[ $color ];
if (empty($translate)) {
$colors_translations[ $color ] = $translate = randHEXcolor();
}
$item[ 0 ] = $translate;
}
The solution using in_array and isset functions:
$keys = [];
foreach ($arr as &$v) { // $arr is your initial array
if (in_array($v[0], ['233', '144'])) {
if (!isset($keys[$v[0]])) $keys[$v[0]] = sprintf('%06X', mt_rand(0, 0xFFFFFF));
$v[0] = $keys[$v[0]];
}
}
print_r($arr);
The output:
Array
(
[0] => Array
(
[0] => 65A4BB
[1] => some data
)
[1] => Array
(
[0] => 65A4BB
[1] => some data
)
[2] => Array
(
[0] => DDB588
[1] => some data
)
[3] => Array
(
[0] => 65A4BB
[1] => some data
)
)
This code will create a color map as the array is traversed. Pre-populate $colorMap if you want pre-defined color translations.
<?php
$array = array(
0 => array(
0 => "233",
1 => "some data"
),
1 => array(
0 => "233",
1 => "some data"
),
2 => array(
0 => "144",
1 => "some data"
),
3 => array(
0 => "233",
1 => "some data"
),
);
$colorMap = array();
foreach ($array as &$inner) {
if (!array_key_exists($inner[0],$colorMap)) {
$newColor = randHEXcolor();
$colorMap[$inner[0]] = $newColor;
$inner[0] = $newColor;
} else {
$inner[0] = $colorMap[$inner[0]];
}
}
function randHEXcolor() {
return sprintf('%06X', mt_rand(0, 0xFFFFFF));
}
print_r($array);
print_r($colorMap);
Array
(
[0] => Array
(
[0] => F1519A
[1] => some data
)
[1] => Array
(
[0] => F1519A
[1] => some data
)
[2] => Array
(
[0] => 2F7D00
[1] => some data
)
[3] => Array
(
[0] => F1519A
[1] => some data
)
)
Array
(
[233] => F1519A
[144] => 2F7D00
)
Try:
<?php
$array = array(
0 => array(
0 => "233",
1 => "some data"
),
1 => array(
0 => "233",
1 => "some data"
),
2 => array(
0 => "144",
1 => "some data"
),
3 => array(
0 => "233",
1 => "some data"
),
);
function randHEXcolor() {
return sprintf('%06X', mt_rand(0, 0xFFFFFF));
}
$firstHex = randHEXcolor();
$secondHex = randHEXcolor();
foreach($array as $arrayIndex => &$arrayValue){
if($arrayValue[0] == "144"){
$arrayValue[0] = $firstHex;
}
if($arrayValue[0] == "233"){
$arrayValue[0] = $secondHex;
}
}
output:
array(4) {
[0]=>
array(2) {
[0]=>
string(6) "AB8248"
[1]=>
string(9) "some data"
}
[1]=>
array(2) {

I would like to switch the main keys(0,1,2) of an array with a subelement key(user_id).
For example, from this array:
array(3) {
[0]=>
array(3) {
["num_products_user_by_ref"]=>
string(1) "1"
["user_id"]=>
string(2) "77"
["reference"]=>
string(3) "E49"
}
[1]=>
array(3) {
["num_products_user_by_ref"]=>
string(1) "9"
["user_id"]=>
string(3) "526"
["reference"]=>
string(3) "E49"
}
[2]=>
array(3) {
["num_products_user_by_ref"]=>
string(2) "38"
["user_id"]=>
string(3) "346"
["reference"]=>
string(3) "E49"
}
}
I need :
array(952) {
[77]=>
array(2) {
["num_products_user_by_ref"]=>
string(1) "1"
["reference"]=>
string(3) "E49"
}
[526]=>
array(3) {
["num_products_user_by_ref"]=>
string(1) "9"
["reference"]=>
string(3) "E49"
}
[346]=>
array(3) {
["num_products_user_by_ref"]=>
string(2) "38"
["reference"]=>
string(3) "E49"
}
Every user_id could contains more than 1 pair num_products_user_by_ref/reference.
I remember that there is a function to achieve this (ksort?) associated to a custom function to implement.
$out = array();
foreach ($arr as $key => $value){
$out[$value['user_id']]["num_products_user_by_ref"] = $value["num_products_user_by_ref"];
$out[$value['user_id']]["reference"] = $value["reference"];
}
print_r($out);
Your question showed a structure that doesn't seem to fit with your comment "Every user_id could contains more than 1 pair num_products_user_by_ref/reference." So, here's another version that allows for that possibility:
$out = array();
foreach ($arr as $key => $value){
$entry = array("num_products_user_by_ref" => $value["num_products_user_by_ref"],
"reference" => $value["reference"]);
$out[$value['user_id']][] = $entry;
}
Output:
Array
(
[77] => Array
(
[0] => Array
(
[num_products_user_by_ref] => 1
[reference] => E49
)
[1] => Array
(
[num_products_user_by_ref] => 5
[reference] => E49
)
)
[526] => Array
(
[0] => Array
(
[num_products_user_by_ref] => 9
[reference] => E49
)
)
[346] => Array
(
[0] => Array
(
[num_products_user_by_ref] => 38
[reference] => E49
)
)
)
Here's another version for those who don't like traditional loops:
$out = array();
array_walk($arr, function($e, $k) use(&$out){
$entry = array("num_products_user_by_ref" => $e["num_products_user_by_ref"],
"reference" => $e["reference"]);
$out[$e['user_id']][] = $entry;
});
I have had success merging two arrays by difference using the following code:
$a=array("2013-08-22"=>"12","2013-08-25"=>"5","2013-08-27"=>"10");
$b=array("2013-08-22"=>"1","2013-08-23"=>"3","2013-08-25"=>"5","2013-08-27"=>"10","2013-08-29"=>"5");
foreach ($b as $key => $value){
if(!array_key_exists($key, $a)){
$a[$key]=0;
}
}
This will return:
Array
(
[2013-08-22] => 0
[2013-08-23] => 0
[2013-08-25] => 5
[2013-08-27] => 10
[2013-08-29] => 0
[2013-12-22] => 12
)
The idea is for a to additionally hold the elements from b that are not present in a.
I am having issues now doing the same thing for the following array format:
$a=array(array("2013-12-22","12"),array("2013-08-25","5"),array("2013-08-27","10"));
$b=array(array("2013-08-22","1"),array("2013-08-23","3"),array("2013-08-25","5"),array("2013-08-27","10"),array("2013-08-29","5"));
I went to try this:
foreach ($b as $key => $value){
if(!array_key_exists($key, $a)){
$a[$key]=array($value[0], 0);
}
}
But the returned result is far from what I need:
Array
(
[0] => Array
(
[0] => 2013-12-22
[1] => 12
)
[1] => Array
(
[0] => 2013-08-25
[1] => 5
)
[2] => Array
(
[0] => 2013-08-27
[1] => 10
)
[3] => Array
(
[0] => 2013-08-27
[1] => 0
)
[4] => Array
(
[0] => 2013-08-29
[1] => 0
)
)
I understand they keys are no longer the dates, but how should I go about checking each array and making sure I don't get double entries?
$a = array(
array("2013-12-22","12"),
array("2013-08-25","5"),
array("2013-08-27","10"));
$b = array(
array("2013-08-22","1"),
array("2013-08-23","3"),
array("2013-08-25","5"),
array("2013-08-27","10"),
array("2013-08-29","5"));
$exists = array();
foreach ($a as $data) {
$exists[$data[0]] = 1;
}
foreach ($b as $data) {
if (array_key_exists($data[0], $exists)) {
continue;
}
$a[] = array($data[0], $data[1]);
}
$a now contains:
array(6) {
[0]=>
array(2) {
[0]=>
string(10) "2013-12-22"
[1]=>
string(2) "12"
}
[1]=>
array(2) {
[0]=>
string(10) "2013-08-25"
[1]=>
string(1) "5"
}
[2]=>
array(2) {
[0]=>
string(10) "2013-08-27"
[1]=>
string(2) "10"
}
[3]=>
array(2) {
[0]=>
string(10) "2013-08-22"
[1]=>
string(1) "1"
}
[4]=>
array(2) {
[0]=>
string(10) "2013-08-23"
[1]=>
string(1) "3"
}
[5]=>
array(2) {
[0]=>
string(10) "2013-08-29"
[1]=>
string(1) "5"
}
}
