I need to map
Array
(
[0] => Array
(
[cid] => 1
[value] => red
)
[1] => Array
(
[cid] => 2
[value] => green
)
[2] => Array
(
[cid] => 3
[value] => pink
)
[3] => Array
(
[cid] => 4
[value] => yellow
)
)
To:
Array
(
[0] => 2
[1] => 3
[2] => 1
)
I need to map the second arrays value [0] => 2 to the cid in the first array. In other words I need 2 to map to value green.
Any help? THANK YOU.
I would first change the first array to something that is easier to check.
<?php
$temp = array();
foreach ($array1 as $val) {
$temp[$val['cid']] = $val['value'];
}
?>
Now you have an array:
$temp[1] = "red";
$temp[2] = "green";
$temp[3] = "pink";
$temp[4] = "yellow";
Then you can easily use that in the second array
<?php
$new= array();
foreach ($array2 as $key=>$val) {
$new[$key] = $temp[$val];
}
?>
Codepad example
PHP >= 5.5.0
$colors = array_column($first, 'value', 'cid');
foreach($second as $value) {
if(isset($colors[$value])) {
echo $colors[$value];
}
}
Where $first is your first array and $second obviously the second.

Here is my array

(
[0] => 119774100
[1] => 2
[2] => 2020-02-22 00:01:01/2020-02-22 00:01:01
[3] => 1
[4] => sports/D50
[5] => sports-1/D50-1
)
)
I want to change these 5 keys in array to (msisdn, logCount, logins, transc, actVas) like this and I have tried by using array_fill_keys
Is there a way to do this ?
You can map and combine:
$array = array_map(function($v) {
return array_combine(["msisdn", "logCount", "logins",
"transc", "actVas", "vasCount"], $v);
}, $array);
Or walk and combine:
array_walk($array, function(&$v) {
$v = array_combine(["msisdn", "logCount", "logins",
"transc", "actVas", "vasCount"], $v);
});
You can do either one with a defined array and use() like:
$k = ["msisdn", "logCount", "logins", "transc", "actVas", "vasCount"];
$array = array_map(function($v) use($k) { return array_combine($k, $v); }, $array);
//or
array_walk($array, function(&$v) use($k) { $v = array_combine($k, $v); });
Assuming you may have a very large array, this will just replace the existing arrays keys rather than making another copy of the array.
$pushed = [
[ 710715609, 3, '2020-02-28 00:01:01/2020-02-25 00:01:01/2020-02-21 00:01:01', 2, 'sports/Mtunes/Astro/D50', 'sports-1/Mtunes-1/Astro-1/D50-2'],
[ 119774100, 2, '2020-02-22 00:01:01/2020-02-22 00:01:01', 1, 'sports/D50', 'sports-1/D50-1']
];
$names = ["msisdn", "logCount", "logins", "transc", "actVas", "vasCount"];
foreach ($pushed as $x => $push){
foreach ($push as $i => $v) {
unset ($pushed[$x][$i]);
$pushed[$x][$names[$i]] = $v;
}
}
print_r($pushed);
RESULT
Array
(
[0] => Array
(
[msisdn] => 710715609
[logCount] => 3
[logins] => 2020-02-28 00:01:01/2020-02-25 00:01:01/2020-02-21 00:01:01
[transc] => 2

o/p:Here am getting the username,logged time and date
Array
( [cena] => Array
(
[CentaurOne] => Array
(
[0] => 29/12/17 01:02:15
[1] => 13/01/18 09:23:21
)
[count] => 2
)
[Bhumi] => Array
(
[CentaurOne] => Array
(
[0] => 29/12/17 01:21:30
[1] => 29/12/17 09:23:11

[count] => 2

[John] => Array

[CentaurOne] => Array
(
[0] => 16/01/18 09:24:01
[1] => 18/01/18 02:51:20
[2] => 18/01/18 01:02:04
[3] => 19/01/18 01:02:04
)
[count] => 3
)
)
Now i needed to get the username according to the users logged in time like given below:
cena 29/12/17 01:02:15
John 18/01/18 01:02:04 ,19/01/18 01:02:04
You could try something like this :
$time = ' 01:02'; // note the begining space
// or use : $time = '01:02:';
$matches = [] ;
foreach ($logs as $login => $data) {
foreach ($data as $name => $dates) {
if (! is_array($dates)) continue ; // avoid search in 'count'
foreach ($dates as $date) {
if (strpos($date, $time) !== false) {
$matches[$login][] = $date ;
}
}
}
}
var_dump($matches) ;

I have an Array format.
Array
(
[0] => Array
(
[order_id] => 1
)
[1] => Array
(
[order_id] => 11
)
[2] => Array
(
[order_id] => 12
)
)
It should to be changed the array format to be like this format:
[1,11,12];
Please help. Thank you in advanced.
For (PHP 5 >= 5.5.0, PHP 7) you can use array_column and lower than that you can use array_map function (for PHP < 5.3) you need to define saperate function for array_map instead of anonymous function.
$array = array
(
'0' => array
(
'order_id' => 1
),
'1' => array
(
'order_id' => 11
),
'2' => array
(
'order_id' => 12
)
);
$new_array = array_column($array, 'order_id');
print_r($new_array);
$new_array = array_map(function($element) {
return $element['order_id'];
}, $array);
print_r($new_array);
output
Array
(
[0] => 1
[1] => 11
[2] => 12
)
How about this?
$arr = Array
(
0 => Array
(
'order_id' => 1
),
1 => Array
(
'order_id'=> 11
),
2 => Array
(
'order_id' => 12
),
);
$newArr = array();
foreach($arr as $x){
foreach($x as $y){
$newArr[] = $y;
}
}
You can try this:
$ar = array(array('order_id' => 1), array('order_id' => 11), array('order_id' => 12));
$temp = array();
foreach ($ar as $val) {
$temp[] = $val['order_id'];
}
print_r($temp);
Basically, you are looking to flatten the array. This SO answer has some tips on how to do that. Also, there's a golf version in this Github gist.
For the specific case in your question, this should do
function specificFlatten($arr) {
if (!is_array($arr)) return false;
$result = [];
foreach ($arr as $arr_1) {
result[] = $arr_1['order_id'];
}
return $result;
}

Array
(
[Item 1] => Array
(
[0] => 8
[1] => 5
[2] => 4
)
[Item 2] => Array
(
[0] => 24
[1] => 4
)
[Item 3] => Array
(
[0] => 23
[1] => 4
)
}
How do I add the array elements together so they become
Array
(
[Item 1] => Array
(
[0] => 17
)
[Item 2] => Array
(
[0] => 28
)
[Item 3] => Array
(
[0] => 27
)
}
I previously use array_merge_recursive to merge 2 array of the same keys together, but now I wanna add their elements together so they only have element [0].
Thanks!
You can use array_map and array_sum to achieve your goal:
$array = array('Item1' => array(1, 3), 'Item2' => array(3, 4));
$array = array_map(function($item) {
return array_sum($item);
}, $array);
echo '<pre>';
var_dump($array);
echo '</pre>';
The result would be:
array(2) {
["Item1"]=>
int(4)
["Item2"]=>
int(7)
}
If you really need the result to be an array with the sum of the items then change the return to:
return array(array_sum($item));
Maybe you can do long way like this
foreach($array as $key => $element){
$sum = 0;
foreach($element as $value){
$sum += $value;
}
$result[$key][0] = $sum;
}
Basically like this you will browse thru every element of array and you will create sum of desired elements

Thanks lets say i have array like this
$array = array('1','1','3','1','2','3','2','2','2','3');
i want to create arrays from the above array but of common elements like
$arr1 = ('1','1','3');
$arr2 = ('1','2','3');
$arr3 = ('2','2','2','3');
where conditions finding value 3 from array.
Is there such a PHP function, I had a browse of the manual but could not see what I was looking for.
I'm not sure what did you mean, but I guess this code will meet your needs
$result = array();
$needle = '3';
$haystack = array('1','1','3','1','2','3','2','2','2','3');
$tmp = array();
foreach ($haystack as $var){
$tmp[] = $var;
if ($var == $needle){
$result[] = $tmp;
$tmp = array();
}
}
if (!empty($tmp)){
$result[] = $tmp;
}
And the result is
Array
(
[0] => Array
(
[0] => 1
[1] => 1
[2] => 3
)
[1] => Array
(
[0] => 1
[1] => 2
[2] => 3
)
[2] => Array
(
[0] => 2
[1] => 2
[2] => 2
[3] => 3
)
)
