I have an array with many dates. These dates are passive. If the free time in between is more than 8 days, i need to get the opposite of these dates. I have to process these opposite dates as the number of day, start date and end date.
Example Array
Array
(
[0] => 17-05-2020
[1] => 18-05-2020
[2] => 19-05-2020
[3] => 20-05-2020
[4] => 28-05-2020
[5] => 29-05-2020
[6] => 30-05-2020
[7] => 02-06-2020
[8] => 03-06-2020
[9] => 10-07-2020
[10] => 10-07-2020
[11] => 11-07-2020
[12] => 12-07-2020
[13] => 13-07-2020
[14] => 20-07-2020
[15] => 21-07-2020
[16] => 25-07-2020
[17] => 26-07-2020
[18] => 27-07-2020
)
The result I want
Array
(
[0] => Array
(
[0] => 30-05-2020
[1] => 02-06-2020
[2] => 3
)
[1] => Array
(
[0] => 13-07-2020
[1] => 20-07-2020
[2] => 7
)
[2] => Array
(
[0] => 21-07-2020
[1] => 25-07-2020
[2] => 4
)
)
What i understood is you want to get difference between dates and if difference is >= 8 then you want those dates in separate array with days counts as well
Do like below:
$finalArray = [];
foreach($array as $key=>$arr){
if(isset($array[$key+1])){
$diff = round((strtotime($array[$key+1]) - strtotime($arr)) / (60 * 60 * 24));
if(($diff < 8) and ($diff > 1)){
$finalArray[] = array(
$arr,
$array[$key+1],
$diff
);
}
}
}
print_r($finalArray);

In my foreach loop, I'm fetching data from csv file, after rendering it in the array, the data is rendered collectively, but I want it to show column wise as in csv file or I have shown in the below second code example:
Array(
[0] => op1
[1] => op2
[2] => ans 1
[3] => op4
[4] => op1
[5] => op2
[6] => ans 2
[7] => op4
[8] => op1
[9] => op2
[10] => ans 3
[11] => op4
[12] => op1
[13] => op2
[14] => ans 4
[15] => op4
[16] => op1
[17] => op2
[18] => ans 5
[19] => op4
[20] => op1
)
I want to this
Array
(
option[0]=>
Array(
[0] => op1
[1] => op2
[2] => ans 1
[3] => op4
)
option[1]=>
Array(
[0] => op1
[1] => op2
[2] => ans 2
[3] => op4
)
option[2]=>
Array(
[0] => op1
[1] => op2
[2] => ans 2
[3] => op4
)
option[3]=>
Array(
[0] => op1
[1] => op2
[2] => ans 2
[3] => op4
)
)
you can use array_chuck() function like this:
print_r(array_chunk($input_array, 4));
In your existing foreach loop use Modulus for divide array in groups.
$final_arr= array();
$new_key = 0;
foreach($csv_data as $key => $value){
$new_key = $new_key;
if($key % 4 == 0){
$new_key += 1;
}
$final_arr[$new_key][]= $value;
}
Here I assume you got your csv data in $csv_data this variable.
Hope it helps to you.
From str_getcsv's manual page, first two comments:
That does not produce the desired results, if fields contain
linebreaks.
Handy one liner to parse a CSV file into an array:
$csv = array_map('str_getcsv', file('data.csv'));
This will create an array of associative arrays with the first row
column headers as the keys.
$csv = array_map('str_getcsv', file($file));
array_walk($csv, function(&$a) use ($csv) {
$a = array_combine($csv[0], $a);
});
array_shift($csv); // remove column header

I have the following array:
Array (
[ids] => Array (
[0] => e348ae92
[1] => 193ba701
[2] => 58695854
)
[name] => Array (
[0] => Customers
[1] => Suppliers
[2] => Users
)
[subs] => Array (
[0] => 614
[1] => 65
[2] => 99
)
)
I want to take each array key and turn it into a it's own array e.g.
array(
[0] = array(
[0] => e348ae92
[1] => custommers
[2] => 614
)
[1] = array(
[0] => 193ba701
[1] => Suppliers
[2] => 65
)
[2] = array (
[0] => 58695854
[1] => Users
[2] => 99
)
)
I have looked at array_merge, array_combine and a few other things but I have been unsuccessful so far, any pointers in the right direction would be appreciated.
You can use array_map
$f = array_map(null, $a['ids'], $a['name'], $a['subs']);
print_r($f);

I have this array (much more longer - only part)
[366] => Array
(
[0] => 8
[1] => 7
[2] => 8
[3] => 9
[4] => 8
)
[367] => Array
(
[0] => 8
[1] => 9
[2] => 9
[3] => 10
[4] => 10
[5] => 9
[6] => 8
[7] => 9
[8] => 10
[9] => 10
[10] => 11
[11] => 10
[12] => 11
[13] => 11
[14] => 10
[15] => 9
[16] => 10
[17] => 8
[18] => 10
)
The keys must be hold (there are an id). I want to sum the values foreach (in this example the values are generations). So Generation 8 is count 3 times for 366.
Expect is for id 366: 7 - 1x, 8 - 3x, 9 - 1x or
[366] => Array
(
[7] => 1
[8] => 3
[9] => 1
)
[367] => Array
(
[8] => 3
[9] => 5
[10] => 8
[11] => 3
)
Every suggestion is welcomed and appreciated!
I´m always stopped with the numeric keys or the foreach ... one of code i´ve tried:
$outdams = array();
foreach ($dams as $key => $value) {
foreach ($value as $key2 => $value2) {
$index = $value2;
if (array_key_exists($index, $outdams)) {
$outdams[$index]++;
} else {
$outdams[$index] = 1;
}
}
}
check this code
<?php
$data = array(366=>array(8,7,8,8,9),
367=>array(8,9,13,14,17,14));
echo "<pre>"; print_r($data);
$response = array();
foreach ($data as $outerkey => $outerData){
foreach ($outerData as $innerkey => $innerData){
//echo "<pre>"; print_r($innerData);
if(array_key_exists($innerData, $response[$outerkey])){
$response[$outerkey][$innerData] ++;
}else{
$response[$outerkey][$innerData] = 1;
}
}
}
echo "<pre>"; print_r($response);
?>

I have a PHP array like the following one and I would like to combine a multi array to one array:
Array
(
[0] => ADB_DW2017
[1] => LM9
[2] => MS_OF2013
)
Array
(
[0] => NK
[1] => PV
[2] => NK
)
Array
(
[0] => 15
[1] => 25
[2] => 10
)
Array
(
[0] => 250
[1] => 111
[2] => 150
)
Array
(
[0] => 450
[1] => 123
[2] => 250
)
Array
(
[0] => 0
[1] => Mien thue
[2] => 5
)
Array
(
[0] => 200
[1] => 12
[2] => 100
)
Array
(
[0] => 6.750
[1] => 3.075
[2] => 2.500
)
I want to combine like this, with the highest performance :
Array
(
[ADB_DW2017]=>array([suppiler]=>NK
[min_pro]=>15
[max_pro]=>250
[avg_pro]=>450
[tax]=>0
[com]=>200
[sum]=>6.750
)
)
My question is : How to combine a multi array to one array in PHP with the highest performance ?
I assume array names are $first_array,$second_array,...... (so change varabile names accordingly).
Do like below:-
$final_array = array();
foreach ($first_array as $key=> $arr){
$final_array[$arr] =array(
'suppiler'=>(isset($second_array[$key]))? $second_array[$key]: '',
'min_pro'=>(isset($third_array[$key]))? $third_array[$key]: 0,
'max_pro'=>(isset($fourth_array[$key]))? $fourth_array[$key]: 0,
'avg_pro'=>(isset($fifth_array[$key]))? $fifth_array[$key]: 0,
'tax'=>(isset($sixth_array[$key]))? $sixth_array[$key]: '',
'com'=>(isset($seventh_array[$key]))? $seventh_array[$key]: 0,
'sum'=>(isset($eigth_array[$key]))? $eigth_array[$key]: 0
);
}
echo "<pre/>";print_r($final_array);

I would like to split the below array into 3 single arrays. However, the size of the array can be any number. The below array size is 3.
Array (
[0] => Array
(
[0] => a
[1] => bb
[2] => c
[3] => dd
[4] => ee
)
[1] => Array
(
[0] => dd
[1] => ff
[2] => hh
[3] => iji
[4] => kkk
[5] => a
[6] => cc
)
[2] => Array
(
[0] => ee
[1] => kk
[2] => iji
[3] => a
[4] => bb
[5] => lmn
[6] => ppq
[7] => xyz
)
)
Expected output:
Array1 (
[0] => a
[1] => bb
[2] => c
[3] => dd
[4] => ee
)
Array2 (
[0] => dd
[1] => ff
[2] => hh
[3] => iji
[4] => kkk
[5] => a
[6] => cc
)
Array3 (
[0] => ee
[1] => kk
[2] => iji
[3] => a
[4] => bb
[5] => lmn
[6] => ppq
[7] => xyz
)
The name of the individual array should be followed by a number that increments for each array.
You can break a 3d array into 3 separate arrays using list().
list($array1, $array2, $array3) = $mainArray;
Here's an example: https://3v4l.org/hQ1Te
Now if you don't know how many arrays are going to be in the input array you can do something like this...
for($i=0; $i<count($mainArray); $i++){
$variableName = "array$i";
$$variableName = $mainArray[$i];
}
var_dump($array1, $array2, $array3, $array4, ...);
So are you looking for something like this?
for ($i = 0; $i < count($inputArray); $i++) {
echo "Array ". $i;
echo "<pre>";
print_r($inputArray[$i]);
echo "</pre>";
}
Edit: ok now I get it, you want:
for ($i = 0; $i < count($inputArray); $i++) {
$name = "array" . ($i + 1);
$$name = $inputArray[$i];
}
