Actually my date is $Date= '03/02/2015';
I want to increment this day with array of days .My array is
Array ( [0] => 1 [1] => 42 [2] => 70 [3] => 98 [4] => 186 [5] => 279 [6] => 372 [7] => 465 [8] => 558 [9] => 730 [10] => 1460 [11] => 4380 [12] => 1825 ).
I stored this array in a variable called $data.I want to increment my date with each of this days and print all result dates.How can i do it???
Try this with this code you can print dates
<?php
$Date = "2015-02-03";
$dataArray = Array ( 1 ,42 , 70 , 98 , 186 , 279 ,372);
foreach($dataArray as $val){
echo date('Y-m-d', strtotime($Date. " + $val days"))."</br>";
}
?>
Use this code
<?php
$Date= '03/02/2015';
$stamp= strtotime($Date);
$days=array(42,70,98,186,279,372,465,558,730,1460,4380,1825); //change these values
$values=array();
foreach($days as $day){
$newstamp=$stamp+($day*24*60*60);
$values[]=date("m/d/Y",$newstamp);
}
//now add to database
mysql_connect('localhost','user','pass'); //change user pass
mysql_select_db('yourdatabase'); //change here
foreach($values as $value) {
$sql="insert into yourtable values('".$value."',xxx,xxxx..))"; //change here
mysql_query($sql);
}
mysql_close();
?>

Grouping arrays in PHP

Closed 9 months ago.
I'm trying to take successful array results and start doing calculations on values based on another value in the array.
To start with, I want to sum every quantity 'TotalQTY' for each customer 'CSTNOC' in these arrays.
The array is printing fine but I'm getting undefined index errors in my last foreach loop.
I feel like this is simple enough but I'm not sure if my array isn't structure properly of if it's an issue with my loop.
Array
(
[0] => Array
(
[CSTNOC] => 1976
[FRAMEC] => 1051
[COVR1C] => 1150
[COLR1C] => 99
[START_DATE] => 2018-03-02
[TOTALQTY] => 2
)
[1] => Array
(
[CSTNOC] => 5400
[FRAMEC] => 1051
[COVR1C] => 1150
[COLR1C] => 99
[START_DATE] => 2017-11-10
[TOTALQTY] => 1
)
[2] => Array
(
[CSTNOC] => 5400
[FRAMEC] => 1051
[COVR1C] => 1150
[COLR1C] => 99
[START_DATE] => 2017-04-07
[TOTALQTY] => 2
)
[3] => Array
(
[CSTNOC] => 5400
[FRAMEC] => 1051
[COVR1C] => 1150
[COLR1C] => 99
[START_DATE] => 2018-02-09
[TOTALQTY] => 2
)
[4] => Array
(
[CSTNOC] => 11316
[FRAMEC] => 1051
[COVR1C] => 1150
[COLR1C] => 99
[START_DATE] => 2017-03-03
[TOTALQTY] => 1
)
I basically want these results for an excel report purpose:
CSTNOC | TotalQTY
1976 | 2
5400 | 5
11316 | 1
This is the portion of the script:
$dealerQuery = "
SELECT
cstnoc,
framec,
covr1c,
colr1c,
cast(Left(extd2d, 4)||'-'||substring(extd2d,5,2)||'-'||substring(extd2d, 7,2) as date) as start_date,
sum(orqtyc) as TotalQTY
from table
where cstnoc = {$skuRow['dealer_id']}
AND framec = {$skuRow['frame']}
AND colr1c = {$skuRow['color']}
AND covr1c = {$skuRow['cover']}
AND extd2d >= " . str_replace('-', '', $skuRow['start_date']) . "
group by cstnoc, framec,covr1c,colr1c,extd2d
";
$dealerRslt = odbc_exec($DB2Conn, $dealerQuery);
foreach($skuResult as $skuRow){
while($dealerRow = odbc_fetch_array($dealerRslt)){
$dealerResult[] = $dealerRow;
$sum = 0;
foreach($dealerResult['cstnoc'] as $dealerRow){
$sum += $dealerRow['TotalQTY'];
}
echo $sum;
}
}
Why are you looping $skuResult, you never use $skuRow? You could probably SUM this in the query, but for PHP:
while($dealerRow = odbc_fetch_array($dealerRslt)){
if(!isset($dealerResult[$dealerRow['cstnoc']])) {
$dealerResult[$dealerRow['cstnoc']] = 0;
}
$dealerResult[$dealerRow['cstnoc']] += $dealerRow['TotalQTY'];
}
Then you can loop to display:
foreach($dealerResult as $cstnoc => $total) {
echo "$cstnoc = $total";
}
Your query shows lowercase cstnoc but your result array shows Uppercase CSTNOC, so use whichever it really is.
You are using the same variable $dealerRow twice.
On:
while($dealerRow = odbc_fetch_array($dealerRslt)){
and in
foreach($dealerResult['cstnoc'] as $dealerRow){
try using another name inside the foreach.
Simple foreach will do the trick.
$new = array();
foreach($arr as $k=>$v){
$new[$v['CSTNOC']] = isset($new[$v['CSTNOC']]) ? $new[$v['CSTNOC']] + $v['TOTALQTY'] : $v['TOTALQTY'];
}
print_r($new);
Demo
I don't want to return DATE (Y-m-d).
I need to print all days until end of month from a given day independently of the month or year.
I tried both [$array as $i] - [$array as $key] and didn't work.
$myday (for example = 19)
return $days
would result:
Array
[0] => 20
[1] => 21
[2] => 22
[3] => 23
...
[31] => 31 || [30] => 30 || [28] => 28
I would need each value for $days to compare each to another field.
Didn't try to use $myday as regular number instead of treating as date. And not use strtotime, mktime....
EDITING
Need something very simple like this one:
$output = array();
for ($i=$myday+1;$i<=31 || $i<=30 || $i<=28;$i++) {
$output[] = $i;
}
But print_r won't do it, I need to return as each value to use in different if conditions
This is easily done using DateTime(), DateInterval(), DatePeriod(), and relative date formats.
$start = (new DateTime())->setDate(date('Y'), date('m'), $myday + 1);
$end = new DateTime('first day of next month');
$interval = new DateInterval('P1D');
$period = new DatePeriod($start, $interval, $end);
$days = array();
foreach($period as $date) {
$days[] = $date->format('d');
}

I'm trying to change the output in order to show it in a chart, do i change it into a json:
foreach ($day as $key => $value) {
$value = explode(" ", $value) ;
$day[$key] = $value ;
$charts[] = array(substr($value[0],0,4).'-'.substr($value[0],4,2).'-'.substr($value[0],6,2),$value[4]) ;
}
$charts = json_encode($charts, JSON_NUMERIC_CHECK) ;
But it displays me this :
[["2013-07-01","1\r"],["2013-07-02","4\r"],["2013-07-03","2\r"],["2013-07-04","1\r"],["2013-07-05","2\r"],["2013-07-08","1\r"],["2013-07-22","1\r"],["2013-07-23","1\r"],["2013-07-25","2\r"],["2013-07-26","3\r"],["2013-07-27","3\r"],["2013-07-28","2\r"],["2013-07-29","5\r"],["2013-07-30","158\r"],["2013-07-31","174\r"]]
why \r does show? any way I can prevent this ?
try
$charts[] = array(substr($value[0],0,4).'-'.substr($value[0],4,2).'-'.substr($value[0],6,2),substr($value[4],0, -1)) ;
You have return characters at the end of your array
[3] => 20130703 5 123 3894971 2\r
They are not visible because \n = new line \r returns the pointer to the beginning of the line.
Your best bet is to use trim() on every element:
foreach ($day as $key => $value) {
$value = explode(" ", trim($value));
$day[$key] = trim($value) ;
$charts[] = array(trim(substr($value[0],0,4).'-'.substr($value[0],4,2).'-'.substr($value[0],6,2),$value[4])) ;
}
It's even better on numbers to use intval(), which ensures datatype to be integer and removes blankspaces, returns, ... too.
I have a script that builds an array of week numbers for the last 12 weeks like so:
$week_numbers = range(date('W'), date('W')-11, -1);
However, if the current week number is 1, then this will return an array like so:
Array
(
[0] => 1
[1] => 0
[2] => -1
[3] => -2
[4] => -3
[5] => -4
[6] => -5
[7] => -6
[8] => -7
[9] => -8
[10] => -9
[11] => -10
)
But I need this array to look like this instead:
Array
(
[0] => 1
[1] => 52
[2] => 51
[3] => 50
[4] => 49
[5] => 48
[6] => 47
[7] => 46
[8] => 45
[9] => 44
[10] => 43
[11] => 42
)
Can anyone see a simple solution to this?
I have thought about doing something like this (not tested):
$current_week_number = date('W');
if($current_week_number<12){
// Calculate the first range of week numbers (for current year)
$this_year_week_numbers = range(date('W'), 1, -1);
// Calculate the next range of week numbers (for last year)
$last_year_week_numbers = range(52, 52-(11-$current_week_number), -1);
// Combine the two arrays to return the week numbers for the last 12 weeks
$week_numbers = array_merge($this_year_week_numbers,$last_year_week_numbers);
}else{
// Calculate the week numbers the easy way
$week_numbers = range(date('W'), date('W')-11, -1);
}
one idea
$i = 1;
while ($i <= 11) {
echo date('W', strtotime("-$i week")); //1 week ago
$i++;
}
if you arent scared of loops you can do this:
$week_numbers = range(date('W'), date('W')-11, -1);
foreach($week_numbers as $key => $value) { if($value < 1) $week_numbers[$key] += 52; }
You can do a modulo % trick:
$week_numbers = range(date('W'), date('W')-11, -1);
foreach ($week_numbers as $i => $number) {
$week_numbers[$i] = (($week_numbers[$i] + 52 - 1) % 52) + 1;
}
// -1 +1 is to change the range from 0-51 to 1-52
I've found that using modulo like this is often useful for date calculations, you can something similar for months, using 12.
Well, I think the easiest way is to create array after getting dates:
$week_numbers = array_map(function($iDay)
{
return ($iDay+52)%52?($iDay+52)%52:52;
}, range(date('W'), date('W')-11));
-note, that you can not do just % since 52%52 will be 0 (and you want 52)
I'm trying to find each missing number in an array like the following.
Array (
[0] => 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 [39] => 40 [40] => 41 [41] => 42 [42] => 43
[43] => 44 [44] => 45 [45] => 46 [46] => 47 [47] => 48 [48] => 49 [49] => 50
[50] => 51 [51] => 52 [52] => 53 [53] => 54 [54] => 55 [55] => 56 [56] => 57
[57] => 58 [58] => 59 [59] => 60 [60] => 61 [61] => 62 [62] => 63 [63] => 64
[64] => 67 [65] => 68 [66] => 69
)
The numbers 65,66 are missing in this particular array.
My question how do I figure out which numbers are missing with the help of PHP. Specifically what I need to find out is the lowest missing number.
Why: Because then I can assign that number to a member as an id.
You can make use of array_diff and range functions as:
// given array. 3 and 6 are missing.
$arr1 = array(1,2,4,5,7);
// construct a new array:1,2....max(given array).
$arr2 = range(1,max($arr1));
// use array_diff to get the missing elements
$missing = array_diff($arr2,$arr1); // (3,6)
I'm assuming the number is the element, not the key, of the array. I'm also assuming that the numbers start from 1, not 0.
$Expected = 1;
foreach ($InputArray as $Key => $Number)
{
if ($Expected != $Number)
{
break;
}
$Expected++;
}
echo $Number;
For big sorted arrays of unique numbers, you can binary search the array for either the lowest or highest unused number. Cost=Log2N. Example: 65536 items can be searched in 16 loops since
if ( arr[hi] - arr[lo] > hi - lo )
... there are unused numbers in that range ...
So (I don't know PHP, but it can be translated...):
lo = first entry index
hi = last entry index
if ( arr[hi] - arr[lo] == hi - lo )
return arr[hi]+1; // no gaps so return highest + 1
do
{
mid = (lo + hi) / 2;
if ( arr[mid] - arr[lo] > mid - lo ) // there is a gap in the bottom half somewhere
hi = mid; // search the bottom half
else
lo = mid; // search the top half
} while ( hi > lo + 1 ); // search until 2 left
return arr[lo]+1;
If given input is not in sorted order and size of input is very large then we can use following logic in any programming language:
Algorithm
bring smaller chunk into memory from large input
initialize three variables say min = 0, max = 0 and missingIds = []
scan smaller chunked input from left to right
if scannedValue found in missingIds
then,
pop scannedValue from missingIds
go to next value;
If scanned value is near to min
then,
find all the missing numbers between scannedValue and min, push into missingIds
min = scannedValue;
Else if scanned value is near to max
then,
find all the missing numbers between scannedValue and max, push into missingIds
max = scannedValue;
repeat above steps until large input scanned from left to right
Example in PHP
<?php
$largeInput = [40,41,42,43,44,45,1,2,3,4,5,6,7,8,9,10,11,12,13,14,35,36,37,38,39,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,67,68,69,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34];
$missingIds = [];
$min = 0;
$max = 0;
$chunkSize = 10;
$chunkNo = 0;
$currentInput = array_slice($largeInput, $chunkNo, $chunkSize);
while(count($currentInput) > 0) {
foreach($currentInput as $id) {
if(in_array($id,$missingIds)) {
$missingIds = array_diff($missingIds,[$id]);
continue;
}
if($id <= $min) {
$distMin = $min - $id;
if($distMin > 2) {
$tempArr = range($id+1,$min-1);
$missingIds = array_merge($missingIds, $tempArr);
$tempArr = [];
} else if ($distMin > 1) {
$tempArr = [$id+1];
$missingIds = array_merge($missingIds, $tempArr);
$tempArr = [];
}
$min = $id;
} else if ($id >= $max){
$distMax = $id - $max;
if($distMax > 2) {
$tempArr = range($max+1,$id-1);
$missingIds = array_merge($missingIds, $tempArr);
$tempArr = [];
} else if ($distMax > 1) {
$tempArr = [$max+1];
$missingIds = array_merge($missingIds, $tempArr);
$tempArr = [];
}
$max = $id;
}
}
$chunkNo++;
$currentInput = array_slice($largeInput, $chunkNo, $chunkSize);
}
print_r($missingIds);
//$idArrayMissing = array([0] => 1, [1] => 2, [2] => 4, [3] => 5, [4] => 6, [5] => 7);
$idArrayMissing = array(1, 2, 4, 5, 6, 7);
//$idArrayFull = array([0] => 1, [1] => 2, [2] => 3, [3] => 4, [4] => 5, [5] => 6);
$idArrayFull = array(1, 2, 3, 4, 5, 6);
function gap($arr)
{
while (list($k, $v) = each($arr))
if ($k != ($v-1))
return $k;
return -1;
}
print "ok:" . gap($idArrayMissing) . "<br/>\n";
print "full:" . gap($idArrayFull) . "<br/>\n";
The return of the gap function can be 2 values:
-1 could indicate that the array has been traversed and there are no free slots or
$k+1 which could indicate that the first free slot is on the end of the array.
It can also be done easily by using in_array() function like this:
// lets say $InputArray has all the data
// lets declare a variable which we will search inside the $InputArray array and lets initialize it with either 0 or 1 or with the minimum value found inside $InputArray
$start_counting = 1;
$max_value = count($InputArray);
if (!(in_array($start_counting, $InputArray)))
{
echo "Value: ".$start_counting." is missing!"."<br>" ;
}
else{
if($start_counting <= $max_value -1)
{$start_counting++;}
}
else if($start_counting > $max_value -1)
{
echo "All missing numbers printed!"
}
}
