Suppose i have 2 arrays:
$array1 =( [0] => Array ( [user] => 'aaa' [count] => '123' )
[1] => Array ( [user] => 'bbb' [count] => '456' )
[2] => Array ( [user] => 'ccc' [count] => '789' ) );
$array2= ( [0] => aaa)
[1] => ccc );
I would like to search values from second array in first array and create the third array that will contain all elements from first array, like this:
$array3 =( [0] => Array ( [user] => 'aaa' [count] => '123' )
[1] => Array ( [user] => 'ccc' [count] => '789' ) );
Please help. Thank you in advance
(sorry for bad english)
$array1 = array(
array( 'user' => 'aaa', 'count' => 123 ),
array( 'user' => 'bbb', 'count' => 456 ),
array( 'user' => 'ccc', 'count' => 789 ),
);
$array2 = array('aaa', 'ccc');
var_dump(array_filter($array1, function($el) use($array2) {
return in_array($el['user'], $array2);
}));
It preserves keys, you can reset them if needed. Or with foreach loop
$out = array();
foreach($array1 as $el)
{
if (in_array($el['user'], $array2))
$out[] = $el;
}
var_dump($out);
Can try using foreach(). Example here...
$array3 = array();
foreach($array2 as $search){
foreach($array1 as $val){
if($search == $val['user']){
$array3[] = $val;
}
}
}
print_r($array3);

I have 2 arrays
$arr1 = Array
(
[REG1] => 94
[REG3] => 45
)
$arr2 =Array
(
[0] => REG1
[1] => REG2
[2] => REG3
[3] => REG4
)
I have to loop 2 arrays and I would like a result in one array like this:
Array(
[0] => Array(
[REG1] => 94
)
[1] => Array(
[REG2] =>
)
[2] => Array(
[REG3] => 45
)
[3] => Array(
[REG4] =>
)
)
But for the instand I can not do what I want, here is where I am:
private function mergeData($arr1, $arr2){
$result = array_map(function($v1, $v2){
$t[$v1] = $v2;
return $t;
}, $arr2, $arr1);
return $result;
}
output:
Array(
[0] => Array(
[REG1] => 94
)
[1] => Array(
[REG2] =>45
)
[2] => Array(
[REG3] =>
)
[3] => Array(
[REG4] =>
)
)
I cannot correctly put the bone values with the right keys.
I tried with array_merge_recursive but also failed.
Thanks for your help
$arr3 = array_fill_keys( $arr2, '' );
creates an array containing the values of $arr2 as keys with as value an empty string.
$arr3 =Array
(
[REG1] => ''
[REG2] => ''
[REG3] => ''
[REG4] => ''
)
After that just merge.
$result = array_merge ( $arr3, $arr1 );
Another option would be to use the array_map function and map key with the corresponding values, if any:
$arr1 = [
'REG1' => 94,
'REG3' => 45
];
$arr2 = [
'REG1',
'REG2',
'REG3',
'REG4'
];
$result = array_map(function($item) use($arr1){
return [$item => isset($arr1[$item]) ? $arr1[$item] : ""];
},$arr2);
This will return:
Array
(
[0] => Array
(
[REG1] => 94
)
[1] => Array
(
[REG2] =>
)
[2] => Array
(
[REG3] => 45
)
[3] => Array
(
[REG4] =>
)
)
Using a loop:
<?php
$arr1 = [
'REG1' => 94,
'REG3' => 45
];
$arr2 = [
'REG1',
'REG2',
'REG3',
'REG4'
];
$result = $arr2;
foreach($result as &$v)
$v = [$v => $arr1[$v] ?? null];
unset($v);
var_export($result);
Output:
array (
0 =>
array (
'REG1' => 94,
),
1 =>
array (
'REG2' => NULL,
),
2 =>
array (
'REG3' => 45,
),
3 =>
array (
'REG4' => NULL,
),
)
I am trying to merge arrays with the same keys with different values, like below.
Input:
$array1 = array('1933' => array(
'nid' => '492811',
'title' => 'NEW TITLE',
'field_link_single_url' => 'abc',
'field_link_single_title' => 'test'
));
$array2 = array('1933' => array(
'nid' => '492811',
'title' => 'NEW TITLE',
'field_link_single_url' => 'xyz',
'field_link_single_title' => 'abcd'
));
Expected output to be:
Array
(
[nid] => 492811
[title] => NEW TITLE
[field_link_single_url] => [
[0] => 'abc',
[1] => 'xyz'
]
[field_link_single_title] => [
[0] => 'test',
[1] => 'abcd'
]
)
I have tried array_merge and array_merge_recursive but it does not work as expected.
Output of array_merge_recursive($array1[1933], $array2[1933]) it is creating duplicates keys having same value
Array
(
[nid] => Array
(
[0] => 492811
[1] => 492811
)
[title] => Array
(
[0] => Hal Louchheim
[1] => Hal Louchheim
)
[field_link_single_url] => Array
(
[0] => abc
[1] => xyz
)
[field_link_single_title] => Array
(
[0] => test
[1] => abcd
)
)
I made some assumption. If these assumptions are not valid, you should add some additional checks:
Both $array1 and $array2 are really arrays
Both $array1 and $array2 have the exact same keys
The values inside $array1 and $array2 are primitive types, not complex objects (the === operator would not work to compare objects or arrays)
function mergeArrayValues($array1, $array2) {
$output = [];
foreach($array1 as $key => $value) {
$output[$key] = $array1[$key] === $array2[$key]
? $array1[$key]
: [ $array1[$key], $array2[$key] ]
}
return $output;
}
mergeArrayValues($array1[1933], $array2[1933])
I want to push another array inside array.
This is my array. I want to push another array on textTabs .
Array
(
[recipients] => Array
(
[signers] => Array
(
[0] => Array
(
[email] => rm#gmail.com
[tabs] => Array
(
[checkboxTabs] => Array
(
[0] => Array
(
[tabLabel] => sampleCheckbox
)
)
[textTabs] => Array
(
[0] => Array
(
[tabLabel] => CompanyName
[value] => Qwerty
)
[1] => Array
(
[tabLabel] => TradingName
[value] => Qwerty
)
[2] => Array
(
[tabLabel] => ContactName
[value] => RM
)
)
)
)
)
)
)
This is my array that i want to add:
$array2 = array(
"tabLabel"=>"MonthlyTotal",
"value"=>$monthlytotal
);
And this is my php code:
$data = array_push($array1['recipients']['signers']['0']['tabs']['textTabs'], $array2);
But I was not able to push it. Thank you for your help.
No need of assignment of array_push() to $data,as child-array pushed to initial array itself. Just do:
array_push($array1['recipients']['signers']['0']['tabs']['textTabs'], $array2);
print_r($array1);
Output:- https://3v4l.org/sntUP
I always prefer doing assignment like below:
$array1['recipients']['signers']['0']['tabs']['textTabs'][] = $array2;
Output:-https://3v4l.org/nHHUB
If you do love a portable way to do add an array or any other values to any key, you may do it using recursive function. Let's see an example below:
<?php
$old_array = [
'one' => 'value for one',
'two' => 'value for two',
'three' => [
'four' => 'value for four',
'five' => 'value for five',
'six' => [
'seven' => 'value for seven',
'eight' => 'value for eight',
],
],
];
function addArrayToKey($array, $callback){
$result = [];
foreach($array as $key => $value){
if(is_array($value)) {
$result[$key] = addArrayToKey($value, $callback);
} else {
$result[$key] = $callback($key, $value);
}
}
return $result;
}
function callback($key, $value) {
if('seven' == $key) {
return ['one', 'two', 'three' => ['four', 'five']];
}
return $value;
}
echo '<pre>';
print_r(addArrayToKey($old_array, 'callback'));
I want to remove key 0 from parent array and set child array as parent.
Here I will get single value so one array is ok for me.
My current array looks like this
Array
(
[0] => Array
(
[id] => 3
[api_key] => acount266
[auth_domain] => Tester26
[database_url] => vcc.test.acc+27#gmail.com
[project_id] => 12345
[storage_bucket] =>
[secret_key_path] =>
[fcm_server_key] => 1
[messaging_sender_id] => 0
[key_phrase] =>
[disable] => 0
[created] =>
[updated] =>
)
)
I want it like below. expected result
Array
(
[id] => 3
[api_key] => acount266
[auth_domain] => Tester26
[database_url] => vcc.test.acc+27#gmail.com
[project_id] => 12345
[storage_bucket] =>
[secret_key_path] =>
[fcm_server_key] => 1
[messaging_sender_id] => 0
[key_phrase] =>
[disable] => 0
[created] =>
[updated] =>
)
For this I tried like below but no success.
$new = array();
foreach ($data as $v){
$new = array_merge($new , array_values($v)) ;
}
but in my code it's removed key e.g id,api_key, etc....
I need key name also in my new array. please suggest
Remove the array_values
Solution
<?php
$test = array(
array
(
'id' => 3,
'api_key' => 'acount266'
)
);
$new = array();
foreach($test as $v){
$new = array_merge($new, $v);
}
var_dump($new);
Result
array(2) {
["id"]=>
int(3)
["api_key"]=>
string(9) "acount266"
}
According to documentation of PHP as mentioned
reset() function returns the value of the first array element, or
FALSE if the array is empty.
$array = array(
array(
'id' => 3,
'api_key' => 'acount266',
'auth_domain' => 'Tester26',
'database_url' => 'vcc.test.acc+27#gmail.com',
'project_id' => '12345',
'storage_bucket' => '',
'secret_key_path' => '',
'fcm_server_key' => 1,
'messaging_sender_id' => 0,
'key_phrase' => '',
'disable' => 0,
'created' => '',
'updated' => ''
)
);
print_r(reset($test));
I tried this:
$arr = array();
foreach ($examples as $example) {
foreach ($example as $e) {
array_push($arr, $e);
}
}
Don't overcomplicate this, reassigning the first element to the parent array is quick and easy:
<?php
$array =
array (
0 =>
array (
'first' => 'Michael',
'last' => 'Thompson'
)
);
$array = $array[0];
var_export($array);
Output:
array (
'first' => 'Michael',
'last' => 'Thompson',
)
Or:
$array = array_shift($array);
I am having array within array values as below.
Array
(
[0] => Array
(
[0] => Array
(
[Floor] => Floor-1
)
[1] => Array
(
[Flat] => Flat A2
)
[2] => Array
(
[Area] => Balcony,
)
)
)
I need to make it as single associative array as below.
Array
(
[0] => Array
(
[Floor] => Floor-1
[Flat] => Flat A2
[Area] => Balcony,
)
)
How can i do this ?
This example should help you.
<?php
$arr = array(
array(
'floor'=>'Floor-1'
),
array(
'Flat'=>'Flat A2'
),
array(
'Area'=>'Balcony,'
),
);
$final_array = array();
foreach ($arr as $arr1) {
foreach ($arr1 as $key => $value) {
$final_array[$key] = $value;
}
}
?>
Output will be
Array
(
[floor] => Floor-1
[Flat] => Flat A2
[Area] => Balcony,
)
Here we have created an empty array called as $final_array we will append this array by using foreach loop.
Remember, if you have a same array key then the last value will overwrite like below.
<?php
$arr = array(
array(
'floor'=>'Floor-1',
'floor'=>'Floor-2',
),
array(
'Flat'=>'Flat A2'
),
array(
'Area'=>'Balcony,'
),
array(
'Area'=>'Balcony2,'
),
);
$final_array = array();
foreach ($arr as $arr1) {
foreach ($arr1 as $key => $value) {
$final_array[$key] = $value;
}
}
?>
Now, output will be
Array
(
[floor] => Floor-2
[Flat] => Flat A2
[Area] => Balcony2,
)
<?php
$array = [
[
[
'foo' => 'big'
],
[
'bar' => 'fat'
],
[
'baz' => 'mamma'
]
]
];
$merged[0] = array_reduce($array[0], function($carry, $item) {
return array_merge((array) $carry, $item);
});
var_export($merged);
Output:
array (
0 =>
array (
'foo' => 'big',
'bar' => 'fat',
'baz' => 'mamma',
),
)
This single line code is enough to do this
$newArr = call_user_func_array('array_merge',$dataArr); ///where $dataArr is your array..
call_user_func_array will call a callback function with array of parameters and array_merge will merge all these parameters in single array read more about call_user_func_array() and array_merge()
Example code:
<?php
$dataArr = array(
array(
'Floor'=>'Floor-1'
),
array(
'Flat'=>'Flat A2'
),
array(
'Area'=>'Balcony,'
),
);
$newArr = call_user_func_array('array_merge',$dataArr);
echo "<pre>"; print_r($newArr);
?>
This will give you :
Array
(
[Floor] => Floor-1
[Flat] => Flat A2
[Area] => Balcony,
)
