I have multidimensional array in which two arrays have multiple array and one has single value which are as below:
$array([0] => array(
[0] => array(
['name'] => 'one',
['number'] => 051
),
[1] => array(
['name'] => 'two',
['number'] => 052
)
),
[1] => array(
['name'] => 'three',
['number'] => 053
),
[2] => array(
[0] => array(
['name'] => 'four',
['number'] => 054
),
[1] => array(
['name'] => 'six',
['number'] => 055
)
)
From above array, how can I get result :
[0] = 051, 052.
[1] = 053.
[2] = 054, 055.
Please help, thank you.
Please try below code:
$var = array(
array(
array(
'name' => 'one',
'number' => '051'
),
array(
'name' => 'two',
'number' => '052'
)
),
array(
'name' => 'three',
'number' => '053'
),
array(
array(
'name' => 'four',
'number' => '054'
), array(
'name' => 'six',
'number' => '055'
)
));
$numbers = [];
foreach ($var as $k => $v) {
$num = [];
if(isset($v['number'])){
$num[] = $v['number'];
}
foreach ($v as $k2 => $v2) {
if(isset($v2['number'])){
$num[] = $v2['number'];
}
}
$numbers[$k] = implode(',', $num) . '.';
}

$array1 = array(
[0] => array(
'id' => 'gdye6378399sjwui39',
'name' => 'Plate 1'
),
[1] => array(
'id' => 'xyz6378399sjwui39',
'name' => 'Plate 2'
),
[2] => array(
'id' => 'tr2e6378399sjwui39',
'name' => 'Plate 3'
)
)
and another array
$array2 = array(
[0] => array(
'id' => 'gdye6378399sjwui39',
'ETA' => '8'
),
[1] => array(
'id' => 'tr2e6378399sjwui39',
'ETA' => '9'
)
[2] => array(
'id' => 'xyz6378399sjwui39',
'ETA' => '5'
)
)
I want to compare the two arrays. I am doing it like this way:-
if(!empty($array2))
{
foreach($array1 as $ck => $cl)
{
foreach($array12 as $ued){
if($cl['id'] == $ued['id'])
{
$array1[$ck]['ETA'] = $ued['ETA'];
break;
}
}
}
What are the other better ways to do this? The order of the two arrays may vary, and so does the size.
If you index the second array by the id (using array_column()) you can get away without using the inner foreach() and just use isset()...
$match = array_column($array2, null, 'id');
foreach ( $array1 as $ck=>$cl) {
if ( isset($match[$cl['id']]) ) {
$array1[$ck]['ETA'] = $match[$cl['id']]['ETA'];
}
}
print_r($array1);
I unload 4 different tables from MySQL with different keys. I need to combine them into one array. I'll sort them by date (but it's not important and I know how to do it).
As I see it:
foreach ($rows2 as $msgs2) {
$arraynew = array_merge($arraynew, array('cost' => $msgs2['vivod'], 'date' => $msgs2['date'], 'type' => '1'));
}
foreach ($rows3 as $msgs3) {
$arraynew = array_merge($arraynew, array('cost' => $msgs3['price'], 'date' => $msgs3['data'], 'type' => '2'));
}
foreach ($rows4 as $msgs4) {
$arraynew = array_merge($arraynew, array('cost' => $msgs4['price'], 'date' => $msgs4['data'], 'type' => '3'));
}
foreach ($rows5 as $msgs5) {
$arraynew = array_merge($arraynew, array('cost' => $msgs5['cost'], 'date' => $msgs5['data'], 'type' => '4'));
}
But it does not work.
<?php
$foos = [
['vivod' => '11', 'date' => '20140112'],
['vivod' => '23', 'date' => '20140113']
];
$bars = [
['price' => '29', 'date' => '20171201'],
['price' => '31', 'date' => '20170102']
];
$result = array();
foreach ($foos as $foo) {
$result[] = array('cost' => $foo['vivod'], 'date' => $foo['date'], 'type' => '1');
}
foreach ($bars as $bar) {
$result[] = array('cost' => $bar['price'], 'date' => $bar['date'], 'type' => '2');
}
var_export($result);
Output:
array (
0 =>
array (
'cost' => '11',
'date' => '20140112',
'type' => '1',
),
1 =>
array (
'cost' => '23',
'date' => '20140113',
'type' => '1',
),
2 =>
array (
'cost' => '29',
'date' => '20171201',
'type' => '2',
),
3 =>
array (
'cost' => '31',
'date' => '20170102',
'type' => '2',
),
)
What you are looking for is array_merge_recursive,
<?php
$ar1 = array("color" => array("favorite" => "red"), 5);
$ar2 = array(10, "color" => array("favorite" => "green", "blue"));
$result = array_merge_recursive($ar1, $ar2);
print_r($result);
?>
Output
Array
(
[color] => Array
(
[favorite] => Array
(
[0] => red
[1] => green
)
[0] => blue
)
[0] => 5
[1] => 10
)
use array_reduce($array, 'array_merge', array()).
Example:
$a = array(array(1, 2, 3), array(4, 5, 6),array(7, 8, 9),array(10, 11, 12));
$result = array_reduce($a, 'array_merge', array());`
In PHP, how can I compare two array and get result in a third array ?
This result must contain old and new values. The goal is to display an HTML table with a header like "field | old value | new value" as this, the user can compare all values one by one.
First array :
$array1 = array(
'key1' => array(
'key1.1' => 'value',
'key1.2' => 'value',
),
'key2' => array(
'key2.1' => 'value',
'key2.2' => 'value',
),
'key3' => array(
array('key3.1' => 'value'),
array('key3.2' => 'value'),
),
);
Second array :
$array2 = array(
'key1' => array(
'key1.1' => 'value',
'key1.2' => 'value',
),
'key2' => array(
'key2.1' => 'value',
'key2.2' => 'value',
),
'key3' => array(
array('key3.1' => 'value'),
array('key3.2' => 'value'),
),
);
What I expect :
$results = array(
'key1' => array(
'key1.1' => array(
'old' => 'old_value',
'new' => 'new_value',
),
'key1.2' => array(
'old' => 'old_value',
'new' => 'new_value',
),
),
'key2' => array(
'key2.1' => array(
'old' => 'old_value',
'new' => 'new_value',
),
'key2.2' => array(
'old' => 'old_value',
'new' => 'new_value',
),
),
'key3' => array(
array(
'key3.1' => array(
'old' => 'old_value',
'new' => 'new_value')
),
array(
'key3.1' => array(
'old' => 'old_value',
'new' => 'new_value'),
)
),
);
What I have already tried without success :
function array_diff_assoc_recursive($array1, $array2) {
$exclude = array(
'custom_key'
);
$difference = array();
foreach($array1 as $key => $value) {
if(is_array($value)){
if( !isset($array2[$key]) || !is_array($array2[$key]) ) {
if(!in_array($key,$exclude)){
$difference[$key]['old'] = $value;
$difference[$key]['new'] = $array2[$key];
}
} else {
$new_diff = array_diff_assoc_recursive($value, $array2[$key]);
if(!empty($new_diff))
$difference[$key] = $new_diff;
}
} else if(!array_key_exists($key,$array2) || $array2[$key] !== $value) {
if(!in_array($key,$exclude)){
$difference[$key]['old'] = $value;
$difference[$key]['new'] = $array2[$key];
}
}
}
return $difference;
}
try this code, i'm sure this will work for you
<?php
echo "<pre>";
$array1 = array(
'key1' => array(
'key1.1' => 'aaa',
'key1.2' => 'xxx',
'key1.3' => 'vvv',
),
'key2' => array(
'key2.1' => 'eee',
'key2.2' => 'fff',
'key2.3' => 'ggg',
),
) ;
echo "Array 1: </br>";
print_r($array1);
$array2 = array(
'key1' => array(
'key1.1' => 'aaa',
'key1.2' => 'ddd',
'key1.3' => 'ccc',
),
'key2' => array(
'key2.1' => 'hhh',
'key2.2' => 'fff',
'key2.3' => 'ttt',
),
);
echo "Array 2:</br>";
print_r($array2);
$result='';
foreach($array1 as $key=> $val)
{
foreach($val as $k=> $v)
{
if($v != $array2[$key][$k])
{
$result[$key][$k]['old']= $array2[$key][$k] ;
$result[$key][$k]['new']= $v;
}
}
}
echo "Compared Result: </br>";
echo "<pre>"; print_r($result);
?>
This will Output
Array 1:
Array
(
[key1] => Array
(
[key1.1] => aaa
[key1.2] => xxx
[key1.3] => vvv
)
[key2] => Array
(
[key2.1] => eee
[key2.2] => fff
[key2.3] => ggg
)
)
Array 2:
Array
(
[key1] => Array
(
[key1.1] => aaa
[key1.2] => ddd
[key1.3] => ccc
)
[key2] => Array
(
[key2.1] => hhh
[key2.2] => fff
[key2.3] => ttt
)
)
Compared Result:
Array
(
[key1] => Array
(
[key1.2] => Array
(
[old] => ddd
[new] => xxx
)
[key1.3] => Array
(
[old] => ccc
[new] => vvv
)
)
[key2] => Array
(
[key2.1] => Array
(
[old] => hhh
[new] => eee
)
[key2.3] => Array
(
[old] => ttt
[new] => ggg
)
)
)
Prepare arrays using array_walk_recursive, and combine them. Please note that the original arrays will be changed
array_walk_recursive($array1, function(&$i) { if(!is_array($i)) $i = array('old'=> $i); });
array_walk_recursive($array2, function(&$i) { if(!is_array($i)) $i = array('new'=> $i); });
print_r(array_merge_recursive($array1, $array2));
demo
This is my array:
$arr = array(
0 => array(
'title' => 'test1',
'count' => 4,
'month' => 'jan-2015'
),
1 => array(
'title' => 'test2',
'count' => 10,
'month' => 'jan-2015'
),
2 => array(
'title' => 'test3',
'count' => 14,
'month' => 'jun-2015'
),
3 => array(
'title' => 'test4',
'count' => 45,
'month' => 'july-2015'
),
);
I've to convert this array into multi-dimentional array as below:
$arr = array(
'jan-2015' => array(
0 => array(
'title' => 'test1',
'count' => 4,
),
1 => array(
'title' => 'test2',
'count' => 10,
),
),
'jun-2015' => array(
0 => array(
'title' => 'test3',
'count' => 14,
),
),
'july-2015' => array(
0 => array(
'title' => 'test4',
'count' => 45,
),
),
);
I've tried to make it as expected but unfortunately i can't make this.
Is any other solutions for this?
According to your data structure :
$arr = array(
0 => array(
'title' => 'test1',
'count' => 4,
'month' => 'jan-2015'
),
1 => array(
'title' => 'test2',
'count' => 10,
'month' => 'jan-2015'
),
2 => array(
'title' => 'test3',
'count' => 14,
'month' => 'jun-2015'
),
3 => array(
'title' => 'test4',
'count' => 45,
'month' => 'july-2015'
),
);
try this:
$newArray = array();
foreach($arr as $key => $val) {
$newArray[$val['month']][] = $val;
}
echo '<pre>'.print_r($newArray,1).'</pre>';
Output:
Array
(
[jan-2015] => Array
(
[0] => Array
(
[title] => test1
[count] => 4
[month] => jan-2015
)
[1] => Array
(
[title] => test2
[count] => 10
[month] => jan-2015
)
)
[jun-2015] => Array
(
[0] => Array
(
[title] => test3
[count] => 14
[month] => jun-2015
)
)
[july-2015] => Array
(
[0] => Array
(
[title] => test4
[count] => 45
[month] => july-2015
)
)
)
You could use this function:
function transform($input) {
// Extract months, and use them as keys, with value set to empty array
// The array_fill_keys also removes duilicates
$output = array_fill_keys(array_column($input, 'month'), array());
foreach ($input as $element) {
$copy = $element;
// remove the month key
unset($copy["month"]);
// assign this to the month key in the output
$output[$element["month"]][] = $copy;
}
return $output;
}
Call it like this:
$arr = array(
0 => array(
'title' => 'test1',
'count' => 4,
'month' => 'jan-2015'
),
1 => array(
'title' => 'test2',
'count' => 10,
'month' => 'jan-2015'
),
2 => array(
'title' => 'test3',
'count' => 14,
'month' => 'jun-2015'
),
3 => array(
'title' => 'test4',
'count' => 45,
'month' => 'july-2015'
),
);
print_r (transform($arr));
Output:
Array
(
[jan-2015] => Array
(
[0] => Array
(
[title] => test1
[count] => 4
)
[1] => Array
(
[title] => test2
[count] => 10
)
)
[jun-2015] => Array
(
[0] => Array
(
[title] => test3
[count] => 14
)
)
[july-2015] => Array
(
[0] => Array
(
[title] => test4
[count] => 45
)
)
)
By using answer of #Girish Patidar, You can achieve this by:
$outputArr = array();
$to_skip = array();
foreach($arr as $row){
$to_skip = $row;
unset($to_skip['month']);
$outputArr[$row['month']][] = $to_skip;
}
echo "<pre>";
print_r($outputArr);
die;
There could many way to do this. Please try this one if it works for you
<?php
$newArr=NULL;
foreach($arr as $array)
{
$temp=NULL;
$temp['title']=$array['title'];
$temp['count']=$array['count'];
$newArr[$array['month']][]=$temp;
}
var_dump($newArr);
?>
I'm having a problem lately that's driving me crazy. I have a multi-dimensional array like this:
$a = array(
'db' => array(
'0' => array(
'id' => '1',
'name' => 'test',
'cat' => array(
'a' => '15',
'b' => '20',
'c' => '30'
),
'canvas' => '2'
),
'1' => array(
'id' => '2',
'name' => 'test2',
'cat' => array(
'a' => '15',
'b' => '20',
'c' => '30'
),
'canvas' => '2'
)
'2' => array(
'id' => '3',
'name' => 'test',
'cat' => array(
'a' => '50',
'b' => '40',
'c' => '90'
),
'canvas' => '1'
)
)
);
And i want to search on it using a function like this: search('canvas = 1');
That would return all the arrays, child of db, that have a key canvas with the value of 1. Or, for example:
search('a = 15');
Would return all arrays that have a key, child of cat, named a and with a value of 15.
$a = array(
'db' => array(
'0' => array(
'id' => '1',
'name' => 'test',
'cat' => array(
'a' => '15',
'b' => '20',
'c' => '30'
),
'canvas' => '2'
),
'1' => array(
'id' => '2',
'name' => 'test2',
'cat' => array(
'a' => '15',
'b' => '20',
'c' => '30'
),
'canvas' => '2'
),
)
);
//checks if array $array contains element with $searchKey key, and $searchVal value
function arrayContains($array, $searchVal, $searchKey) {
if (!is_array($array))
return false;
foreach ($array as $key => $value) {
if ($key === $searchKey && $searchVal === $value)
return true;
if (is_array($value) && arrayContains($value, $searchVal, $searchKey))
return true;
}
return false;
}
function search($a, $search) {
list($searchKey, $searchVal) = explode('=', $search);
$result = array();
foreach($a as $val) {
if (arrayContains($val, $searchVal, $searchKey))
$result[] = $val;
}
return $result;
}
print_r(search($a['db'], "a=15"));
print_r(search($a['db'], "canvas=1"));
Which produces this output(outputs sub-arrays of $a['db'] which contain searched key=>value pair):
Array
(
[0] => Array
(
[id] => 1
[name] => test
[cat] => Array
(
[a] => 15
[b] => 20
[c] => 30
)
[canvas] => 2
)
[1] => Array
(
[id] => 2
[name] => test2
[cat] => Array
(
[a] => 15
[b] => 20
[c] => 30
)
[canvas] => 2
)
)
Array
(
[0] => Array
(
[id] => 3
[name] => test
[cat] => Array
(
[a] => 50
[b] => 40
[c] => 90
)
[canvas] => 1
)
)
Just check the below link if this can help you -
http://php.net/manual/en/function.array-search.php
It contains detailed documentation of php function array_search() and various user codes for searching in multi-dimensional array along with user reviews.
function search($array, $canvas)
{
$result = array();
foreach ($array as $k1 => $v1) {
foreach ($v1 as $k2 => $v2) {
if ($v2['canvas'] == $canvas) {
$result[] = $array[$k1][$k2];
}
}
}
return $result;
}
// $a = your array
print_r(search($a, 1));
