Whenever someone adds an 'item' on my website, I log the item number in a file called items_added.log. I want to make a script which shows me the 5 most commonly added items. Let's say this is my array:
1 => 100
2 => 200
3 => 300
4 => 400
5 => 500
6 => 600
7 => 700
8 => 800
9 => 900
10 => 1000
In this case, I would want to print this array;
10 => 1000
9 => 900
8 => 800
7 => 700
6 => 600
5 => 500
How can I do so? Here's my code so far:
<?php
$file = 'items_added.log';
$content = file_get_contents($file);
$arrItems = explode("\n", $content);
function array_count_values_of($value, $array) {
$counts = array_count_values($array);
return $counts[$value];
}
$itemCounts = array();
foreach($arrItems as $item) {
$itemCounts[$item] = array_count_values_of($item, $arrItems);
}
// Somehow print the 5 largest values (the 5 most commonly added items)
// $itemCounts is an array which contains all items ever added & how many times they have been added
// The structure is ItemNumber => Frequency
?>
You should use arsort, this sorts the array on the value (but in reverse, so from highest to lowest).
arsort($itemCounts);
$top5 = array_slice($itemCounts, 0, 5);
Then you have the $top5 of your array in the variable $top5.
Try arsort and array_splice.
No need to use any custom code.
<?php
$arr = [
1 => 100,
2 => 200,
3 => 300,
4 => 400,
5 => 500,
6 => 600,
7 => 700,
8 => 800,
9 => 900,
10 => 1000
];
arsort($arr);
$arr = array_slice($arr, 0, 5, 1);
print_r($arr);
?>
Hope that helps. Please let me know in case of further issues.
<?php
$arr = [
1 => 100,
2 => 200,
3 => 300,
4 => 400,
5 => 500,
6 => 600,
7 => 700,
8 => 800,
9 => 900,
10 => 1000
];
rsort($arr);
print_r($arr);
?>

this questin is asked many times but every one using same array but in my case i have 2 arrays
consider i have 2 arrays
array1:3 [
10 => 900.0
20 => 450.0
30 => 600.0
]
array2:3 [
30 => 200.0
10 => 500.0
20 => 600.0
]
output should be
[900.0 - 500 = 400 // according to same id 10 = 10
450.0 - 600 = -150 // 20 = 20
600.0 - 200 = 400 // 30 = 30
]
in this array consider 10,20,30 are ids and next is value i want output where compare ever id and get difference example if (id1 = id2 ){ id1 => value - id2 => value }
i need help in that code which i already tried
$getsellerreport = SellerSellsReport::where('seller_id' , $seller_id);
$getunitdiff = $getsellerreport->pluck('unit')->toArray();// [0 => 75 1 => 500 => 100]
$getamountdiff = $getsellerreport->pluck('amount')->toArray(); // [0 => 11000 => 40 2 => 900]
$getproductdiff = $getsellerreport->pluck('product_id')->toArray(); // [0 => 39 1 => 242 => 23]
foreach($product_report as $preport){
$unit[] = $preport['unit'];// [0 => 75 1 => 25 2 => 100]
$amount[] = $preport['amount'];// [0 => 900 1 => 450 2 => 600]
$product_id[] = $preport['product_id'];// [0 => 23 1 => 242 => 39]
} // here we get array two values
above code get values with starting 0 key value and on below for() loop we can use product_id to compare both product id and get unit and amount but i dont know how i can do that can someone help me?
for ($i = 0 ; $i < sizeof($amount) ; $i++){
$unitdiff[] = $getunitdiff[$i] - $unit[$i];
$amountdiff[] = $getamountdiff[$i] - $amount[$i];
}
You could collect the arrays and use map, here is a sample to get you started:
$a = [
10 => 900.0,
20 => 450.0,
30 => 600.0,
];
$b = [
30 => 200.0,
10 => 500.0,
20 => 600.0,
];
$x = collect($a)->map(function($aItem, $index) use ($b) {
return $aItem - $b[$index];
});
dd($x); // yields [ 10 => 400.0, 20 => -150.0, 30 => 400.0 ]
Hello guys I have a small question that suppose I have a string as
"Hello My name is XYZ"
Now I know I can find the length of the words as "Hello" has 5 characters and "My" has 2 characters. By using following code
$text = file_get_contents('text.txt'); // $text = 'Hello my name is XYZ';
$words = str_word_count($text, 1);
$wordsLength = array_map(
function($word) { return mb_strlen($word, 'UTF-8'); },
$words
);
var_dump(array_combine($words, $wordsLength));
But what if i want to find that the number of words with length 1 is 0. The number of words with lengths 2 is 2. The number of words with length 3 is 1 and so on till number of length 10
Note- I am considering the word length till there is a space Suppose there is a date in the data like 20.04.2016 so it should show me that the number is words with length 10 is 1.
and one more thing how do I find the average length for the words in the string.
Thank you in advance
If you use array_count_values() on the $wordsLength array it will give a count of the string lengths there are. If you use this and a template array (created using array_fill()) with the elements 1-10 and a value of 0. You will get a list of all of the word counts...
$counts = array_replace(array_fill(1, 9, 0),
array_count_values($wordsLength));
will give...
Array
(
[1] => 0
[2] => 2
[3] => 1
[4] => 1
[5] => 1
[6] => 0
[7] => 0
[8] => 0
[9] => 0
)
Hi try this it works on the date and special chars,emojis
$text = 'Hello 20.04.2016 🚩 my face😘face is XYZ';
$words =preg_split('/\s+/', $text);
$wordsLength = array_map(
function($word) { return mb_strlen($word, 'UTF-8'); } ,$words);
print_r($words);
//Get Average word Length
$avg=round(array_sum($wordsLength)/count($words),1);
//print Avg
print($avg);
?>
(Demo)
$text = ' Hello 20.04.2016 🚩 my incredibleness face😘face is XYZ ';
Generate array of continuous visible characters
$words = preg_split('/\s+/', $text, 0, PREG_SPLIT_NO_EMPTY);
array (
0 => 'Hello',
1 => '20.04.2016',
2 => '🚩',
3 => 'my',
4 => 'incredibleness',
5 => 'face😘face',
6 => 'is',
7 => 'XYZ',
)
Replace visible strings with their multibyte length notice the simpler syntax
$wordsLength = array_map('mb_strlen', $words);
array (
0 => 5,
1 => 10,
2 => 1,
3 => 2,
4 => 14,
5 => 9,
6 => 2,
7 => 3,
)
Group and count lengths
$lengthCounts = array_count_values($wordsLength);
array (
5 => 1,
10 => 1,
1 => 1,
2 => 2,
14 => 1,
9 => 1,
3 => 1,
)
Establish an array of defaults, because $lengthCounts may have gaps
$defaultCounts = array_fill_keys(range(1,10), 0);
array (
1 => 0,
2 => 0,
3 => 0,
4 => 0,
5 => 0,
6 => 0,
7 => 0,
8 => 0,
9 => 0,
10 => 0,
)
Filter the counts to remove elements/counts that are out-of-range
$filteredCounts = array_intersect_key($lengthCounts, $defaultCounts);
array (
5 => 1,
10 => 1,
1 => 1,
2 => 2,
9 => 1,
3 => 1,
)
Overwrite the defaults with found counts to prevent gaps in the output
$gaplessCounts = array_replace($defaultCounts, $filteredCounts);
array (
1 => 1,
2 => 2,
3 => 1,
4 => 0,
5 => 1,
6 => 0,
7 => 0,
8 => 0,
9 => 1,
10 => 1,
)
I have to make this kind of structure in array;
We have three ( 3 ) variables which creates this structure:
$numberOfParticipants = 38; // 38 is example
$numberOfParticipantsPerHeat = 8 // 8 is example
$numberOfHeats = 5; // 5 is example
Based on this variables I have this table:
The problem is that, I can't place the ' - ' or null after 31 OR 38. The task is that i have to make the arrays of array "almost equal" like the photo and must depend on the variables above. By the way, after I create the correct list I will slice the array to 5 or 6 or whatever parts I need this is not the problem, the problem is that I have to parse the list like this first. This is what I tried so far:
$calc1 = (int)round($numberOfParticipants * $numberOfParticipantsPerHeat, -1); //First round the numberOfParticipants to closest integer by 10
$readyArr = [];
for ($i = 1; $i <= $calc1; $i++) {
if ($i <= $numberOfParticipants) {
$readyArr[$i] = $i;
} else {
$readyArr[$i] = null;
}
}
The problem with this snippet is that it places the null at the end of the list not after 31, or based on the var.
This is the result I have:
array:40 [â–¼
1 => 1
2 => 2
3 => 3
4 => 4
5 => 5
6 => 6
7 => 7
8 => 8
9 => 9
10 => 10
11 => 11
12 => 12
13 => 13
14 => 14
15 => 15
16 => 16
17 => 17
18 => 18
19 => 19
20 => 20
21 => 21
22 => 22
23 => 23
24 => 24
25 => 25
26 => 26
27 => 27
28 => 28
29 => 29
30 => 30
31 => 31
32 => 32
33 => 33
34 => 34
35 => 35
36 => 36
37 => 37
38 => 38
39 => null
40 => null
]
The Array after partition I want should be:
array(
0 => array(0 => 1, 1 => 2, 2 => 3, 3 => 4, 4 => 5, 5 => 6, 6 => 7, 7 => 8,),
1 => array(0 => 9, 1 => 10, 2 => 11, 3 => 12, 4 => 13, 5 => 14, 6 => 15, 7 => 16,),
2 => array(0 => 17, 1 => 18, 2 => 19, 3 => 20, 4 => 21, 5 => 22, 6 => 23, 7 => 24,),
3 => array(0 => 25, 1 => 26, 2 => 27, 3 => 28, 4 => 29, 5 => 30, 6 => 31, 7 => null,),
4 => array(0 => 32, 1 => 33, 2 => 34, 3 => 35, 4 => 36, 5 => 37, 6 => 38, 7 => null,),
);
Every help, every clue will be highly appreciated.
There are two things you need to know about the target structure:
How many players are in the first (which will always be the largest, if only by one) set.
$playersPerHeat = ceil($numberOfParticipants / $numberOfHeats);
// note this replaces your hard-coded $numberOfParticipantsPerHeat
You also need to know how many heats actually have that many, that is how many heats are actually full.
$fullHeats = $numberOfParticipants % $numberOfHeats ?: $numberOfHeats;
// The ?: bit means that if we get zero (ie. all equal heats), then we
// count all the heats instead, since they're all full.
Now it's easy!
$players = range(1,$numberOfParticipants);
$heats = array_merge(
array_chunk(
array_slice($players, 0, $fullHeats * $playersPerHeat),
$playersPerHeat
),
array_chunk(
array_slice($players, $fullHeats * $playersPerHeat),
$playersPerHeat - 1
)
);
That's it! Demo
I want to calculate the totals for a series of columns in a table, how do I go about doing this?
Here is a sample of the data I want to sum:
array:1 [
"traders" => array:6 [
"Jim Mayor__targeted_target" => array:2 [
"amounts" => array:13 [
0 => 5
1 => 5
2 => 0
3 => 0
4 => 0
5 => 0
6 => 0
7 => 0
8 => 0
9 => 0
10 => 0
11 => 0
]
"row_name" => "Targeted target"
]
"Jim Mayor__actual_targeted" => array:2 [
"amounts" => array:13 [
0 => 0
1 => 1
2 => 0
3 => 0
4 => 0
5 => 0
6 => 1
7 => 1
8 => 0
9 => 0
10 => 0
11 => 0
]
"row_name" => "Actual targeted"
]
"Bob Martinez__targeted_target" => array:2 [
"amounts" => array:13 [
0 => 1
1 => 0
2 => 0
3 => 0
4 => 0
5 => 0
6 => 0
7 => 0
8 => 0
9 => 0
10 => 0
11 => 0
]
"row_name" => "Targeted target"
]
"Bob Martinez__actual_targeted" => array:2 [
"amounts" => array:13 [
0 => 19
1 => 45
2 => 20
3 => 26
4 => 21
5 => 10
6 => 12
7 => 20
8 => 11
9 => 2
10 => 0
11 => 0
]
"row_name" => "Actual targeted"
]
...
I want to sum together each index, e.g. for Jim Mayor__targeted_target, index 0 added to index 0 of Bob Martinez__targeted_target (this gives the total for January). It needs to work with an unlimited number of traders.
The function that generates the data:
protected function addRow($func, $params, $data, $year, $traderName, $rowName, $type, $image = null, $format = null, $underline = false)
{
$date = Carbon::createFromDate($year, 4, 1);
$total = 0;
$traderName = $traderName . '__' . str_replace(' ', '_', strtolower($rowName));
for ($i = 1; $i < 13; $i++) {
$params[1] = $date->year;
$params[2] = $date->month;
$result = call_user_func_array($func, $params);
$data['traders'][$traderName]['amounts'][] = $result ? $result : 0;
$total += $result;
$date->addMonth();
}
$data['traders'][$traderName]['amounts'][] = $total;
$data['traders'][$traderName]['row_name'] = $rowName;
return $data;
}
Just go over your data and save results in an additional array:
$results = array();
foreach ($traders as $trader) {
foreach ($trader['amounts'] as $i => $amount) {
if (!isset($results[$i])) {
$results[$i] = 0;
}
$results[$i] += $amount;
}
}
The result array will contains the sums of all traders.
Not tested but should work.
Do something like this:
function sumRowsByMonth($traders)
{
$sums = array_fill(0, 12, 0);
foreach($traders as $trader) {
foreach($trader['amounts'] as $monthId => $amount) {
$sums[$monthId] += $amount;
}
}
return $sums;
}
I tested with this:
$arr = array(
'traders' => array(
'Jim Mayor__targeted_target' => array(
'amounts' => array(
0 => 5,
1 => 5,
2 => 0,
3 => 0,
4 => 0,
5 => 0,
6 => 0,
7 => 0,
8 => 0,
9 => 0,
10 => 0,
11 => 0,
)
),
'Bob Martinez__targeted_target' => array(
'amounts' => array(
0 => 19,
1 => 45,
2 => 20,
3 => 26,
4 => 21,
5 => 10,
6 => 12,
7 => 20,
8 => 11,
9 => 2,
10 => 0,
11 => 0,
)
),
),
);
var_dump(sumRowsByMonth($arr['traders']));
Use array_sum() function.
array_sum() returns the sum of values in an array
Also, you said you want to count targeted target and actual targeted separately.
$actual = [];
$targeted = [];
foreach ($traders as $trader) {
$sum = array_sum($trader['anmounts']);
$trader['row_name'] === 'Actual targeted') ? $actual += $sum : $target += $sum;
}
Maybe you'll need to modify this a little bit to tune behavior, but I guess I got the idea.
#imperium2335:
The main problem I keep getting that it is summing all rows, including actual_targeted. actual_targeted needs to be grouped and summed separately to targeted_target.
Then do this:
function sumRowsByMonth($traders)
{
$sums = array();
foreach($traders as $traderName => $trader) {
$type = strstr($traderName, '__');
if( empty($sums[$type]) ) {
$sums[$type] = array_fill(0, 12, 0);
}
foreach($trader['amounts'] as $monthId => $amount) {
$sums[$type][$monthId] += $amount;
}
}
return $sums;
}

In PHP I have an Array like this:
$BulkArray[$i]
This Array is feed with plenty of Numbers (e.g. 1 => 100, 2 => 300, 3 => 100, and so on).
Now I want to find within the whole range of numbers, the greatest succession of a number equal or less than 500. I want to write the number of succession.
for example I have the array
1 => 100, 2 => 300, 3 => 100,
4 => 50, 5 => 50, 6 => 50, 7 => 50, 8 => 50,
9 => 500, 10 => 200, 11 => 100
as you can see, number 1,2 & 3 are together 500. So this is the first succession.
2,3,4,5 are also 500 together. (This succession(4) is bigger than the first succession(3))
And so on,then you will get the highest succession: 3,4,5,6,7,8 (succession with 6 numbers) which is 350 (but lower than 500m, as we searched for it)
Now, how can I write with the Array:
$BulkArray[$i], that the highest succession is 6 ?
Because 6 is the highest succession found in the whole array for 500!
(It's for categorizing specific Carparts)
The answer of User "fas M" here again, with little improvement:
<?php //lets call your $BulkArray = $values;
$values=array( 1 => 100, 2 => 300, 3 => 100,
4 => 50, 5 => 50, 6 => 50, 7 => 50, 8 => 50,
9 => 500, 10 => 200, 11 => 100 );
$sum=0; // to sum up until 500
$Vals500=array(); // array to store index with <= 500
$i=0; // index for new aaray that will store keys that made up <= 500
$key1=1; //value to iterate the array defined above
for($key=1; $key <= count($values); $key++){
$sum = $sum + $values[$key]; // get sum of values
if($sum <= 500){ $Vals500[$i][]=$key; } //append all key of sum ==500
if($sum >= 500) { $i++; $key=$key1++; $sum=0; } //check sum then reintialize
//added bigger equal
}
echo count(max($Vals500)); // read out the biggest succession
?>
