I have this array
$date = array{"2013-09-17 00:21:00",
"2013-09-23 00:12:00",
"2013-09-23 00:41:00",
"2013-09-20 00:13:00",
"2013-09-19 00:34:00",
"2013-09-17 00:38:00"}
I'm trying to sum the time inside the array that have the same date.
This is my expected output:
$date = array{"2013-09-17 00:59:00",
"2013-09-23 00:53:00",
"2013-09-20 00:13:00",
"2013-09-19 00:34:00"}
Now this is what I have tried so far
foreach($date as $key => $value)
{
$lf_date[] = date("Y-m-d",strtotime($value));
$lf_time[] = date("H:i:s",strtotime($value));
if(isset($lf_date[$key]))
{
$output[] += $lf_time[$key];
}
else
{
$output[] = $lf_time[$key];
}
}
This gives me a 0 output T_T.. I already tried searching on google and it says that I have to use isset and array_key_exists but I can't get it to work. :(. Thanks for anyone who could help me.
Use:
<?php
$date = array("2013-09-17 00:21:00",
"2013-09-23 00:12:00",
"2013-09-23 00:41:00",
"2013-09-20 00:13:00",
"2013-09-19 00:34:00",
"2013-09-17 00:38:00");
$array = array();
foreach($date as $key => $value)
{
$lf_date = date("Y-m-d",strtotime($value));
$lf_time = date("H:i:s",strtotime($value));
$midnight = strtotime("0:00");
if(!isset($array[$lf_date]))
$array[$lf_date] = 0;//check is array index exists
$array[$lf_date] += strtotime($lf_time) - $midnight;
}
foreach($array as $key => $value)
{
$midnight = strtotime("0:00");
$array[$key] = $key." ".date("G:i:s", $midnight + $value);
}
$result = array_values($array);
print_r($result);
?>
Output:
Array
(
[0] => 2013-09-17 0:59:00
[1] => 2013-09-23 0:53:00
[2] => 2013-09-20 0:13:00
[3] => 2013-09-19 0:34:00
)

I have a problem approaching an issue i have, i need to group arrays by key value
I have 3 foreach functions
foreach ($report_phonecall as $key=>$value) {
$phonecalls[$value['datum']] = $value['broj'];
};
foreach ($report_meeting as $key=>$value) {
$meetings[$value['datum']] = $value['broj'];
}
foreach ($report_notes as $key=>$value) {
$notes[$value['datum']] = $value['broj'];
}
That give me array
$phonecall = Array ( [2016-07-13] => 2 [2016-07-14] => 1 [2016-07-19] =>1 )
$meetings = Array ( [2016-07-13] => 1 [2016-07-14] => 1 )
$notes = Array ( [2016-07-19] => 1 )
I need to merge them into 1 array foreach date like this
Array(2016-07-13 => array([phonecalls]=>2, [meetings]=>1, [notes]=>0)) 2016-07-14 => array([phonecalls]=>1, [meetings]=> 1, [notes]=>0).... etc
I want to group/sort them by key value.
Going by
$group_reports[$value[key]] = $value['broj'][$phonecalls][$meetings][$notes]
Im not sure how to define it
How about like this?
$phonecall = ['2016-07-13' => 2, '2016-07-14' => 1, '2016-07-19' => 1];
$meetings = ['2016-07-13' => 1, '2016-07-14' => 1];
$notes = ['2016-07-19' => 1];
// Get *all* possible dates
$keys = array_unique(array_keys($phonecall+$meetings+$notes));
foreach($keys as $key) {
$final[$key] = [
'phonecalls' => isset($phonecall[$key]) ? $phonecall[$key] : 0,
'meetings' => isset($meetings[$key]) ? $meetings[$key] : 0,
'notes' => isset($notes[$key]) ? $notes[$key] : 0
];
}
Please use below code for merge array
$finalArr = array();
foreach($phonecall as $key=>$val){
$finalArr[$key]['phonecalls'] = $val;
$finalArr[$key]['meetings'] = 0;
$finalArr[$key]['notes'] = 0;
}
foreach($meetings as $key=>$val){
if(array_key_exists($key, $finalArr)){
$finalArr[$key]['meetings'] = $val;
} else {
$finalArr[$key]['phonecalls'] = 0;
$finalArr[$key]['meetings'] = $val;
$finalArr[$key]['notes'] = 0;
}
}
foreach($notes as $key=>$val){
if(array_key_exists($key, $finalArr)){
$finalArr[$key]['notes'] = $val;
} else {
$finalArr[$key]['phonecalls'] = 0;
$finalArr[$key]['meetings'] = 0;
$finalArr[$key]['notes'] = $val;
}
}
I am trying to create a schedule of who uses a specific item on which day.
I have 2 arrays.
one with dates &
another with names and how many days they can use the item.
i have managed to create dates array using this.
function dateArray($from, $to, $value = NULL) {
$begin = new DateTime($from);
$end = new DateTime($to);
$interval = DateInterval::createFromDateString('1 day');
$days = new DatePeriod($begin, $interval, $end);
$baseArray = array();
foreach ($days as $day) {
$dateKey = $day->format("d-m-Y");
$baseArray[$dateKey] = $value;
}
return $baseArray;
}
$dates_array = dateArray('01-01-2014', '30-09-2014',true);
print_r($dates_array );
which gives me dates as
Array
(
[01-01-2014] => 1
[02-01-2014] => 1
[03-01-2014] => 1
[04-01-2014] => 1
[05-01-2014] => 1
[06-01-2014] => 1
[07-01-2014] => 1
[08-01-2014] => 1
[09-01-2014] => 1
and so on.
)
i have another array of names having name as key and days as value , they can use the item like this.
$names_array = array("name1" => "4", "name2" => "3", "name3" => "1");
Now i would like to assign names to dates depending on how many days the person can use the item.
like this.
I need my final output array to be like this
Array
(
[01-01-2014] => name1
[02-01-2014] => name1
[03-01-2014] => name1
[04-01-2014] => name1
[05-01-2014] => name2
[06-01-2014] => name2
[07-01-2014] => name2
[08-01-2014] => name3
[09-01-2014] => name1
and so on. notice name1 comes again
)
so i am trying to get output like above but i am failing at the while loop inside the foreach.
so far i have tried this.
function dateArray($from, $to, $value = NULL) {
$begin = new DateTime($from);
$end = new DateTime($to);
$interval = DateInterval::createFromDateString('1 day');
$days = new DatePeriod($begin, $interval, $end);
$baseArray = array();
foreach ($days as $day) {
$dateKey = $day->format("d-m-Y");
$baseArray[$dateKey] = $value;
}
return $baseArray;
}
$dates_array = dateArray('01-01-2014', '30-09-2014',true);
$names_array = array("name1" => "4", "name2" => "3", "name3" => "1");
print_r($dates_array );
$new_dates = array();
foreach($dates_array as $dates => $key){
//echo $dates;
foreach ($names_array as $name => $days){
while($days <= 1){
$new_dates[$dates] = $name ;
$days = $days - 1;
}
}
}
print_r($new_dates);
But my final array is empty.
so how can i solve this ?
You can use a MultipleIterator whereby the second array (names) loops around when needed:
$names_array = array();
// unwind the array values
foreach (array("name1" => "4", "name2" => "3", "name3" => "1") as $value => $freq) {
for ($i = 0; $i < $freq; ++$i) {
$names_array[] = $value;
}
}
// attach both arrays
$m = new MultipleIterator;
$m->attachIterator(new ArrayIterator(array_keys($dates_array)));
$m->attachIterator(new InfiniteIterator(new ArrayIterator($names_array)));
// build final array
$result = array();
foreach ($m as $value) {
$result[$value[0]] = $value[1];
}
It should probably go like this...
while($days <= 1){
$new_dates[$dates] = $name ;
$names_array[$name] = $days - 1;
}
Hi You can try this one
$dates_array = array_keys(dateArray('01-01-2014', '30-09-2014',true));
$names_array = array("name1" => "4", "name2" => "3", "name3" => "1");
$new_dates = array();
$daysindex = 0;
while($daysindex < count($dates_array)){
foreach ($names_array as $name => $day){
for($x = 0; $x<$day; $x++){
if(isset($dates_array[$daysindex])){
$new_dates[$dates_array[$daysindex]] = $name ;
$daysindex++;
}
}
}
}
print_r($new_dates);
$dates = dateArray('01-01-2014', '30-09-2014',true);
$names = array('name1' => 4,'name2' => 3,'name3' => 1);
$count = current($names);
$name = key($names);
foreach($dates as &$value) {
$value = $name;
//if we've displayed a name $count times, move to the next name
if(--$count == 0) {
//if we're at the end of $names, wrap around
if(false === next($names)) {
reset($names);
}
$count = current($names);
$name = key($names);
}
}
print_r($dates);
For a rent application, I have an array $dates like this:
Array
(
[2013-07-19] => 1
[2013-07-21] => 3
[2013-07-23] => 2
[2013-07-24] => 4
[2013-07-25] => 4
[2013-07-26] => 2
[2013-07-27] => 2
[2013-07-30] => 3
[2013-07-31] => 1
)
The date is the key, and the values are the number of items rent in that day for a specific product
How can I split this array in many sub arrays containing each a list of consecutive days?
Like this:
Array
(
[0] => Array
(
[2013-07-19] => 1
)
[1] => Array
(
[2013-07-21] => 3
)
[2] => Array
(
[2013-07-23] => 2
[2013-07-24] => 4
[2013-07-25] => 4
[2013-07-26] => 2
[2013-07-27] => 2
)
[3] => Array
(
[2013-07-30] => 3
[2013-07-31] => 1
)
)
$newArray = array();
foreach ($array as $date => $value)
{
// Make sure the newArray starts off with at least one element
if (empty($newArray))
$newArray[] = array();
// Calculate the difference in dates.
// (I like using DateTime, but use whichever method you like)
$dateTime = new DateTime($date);
$lastDateTime = new DateTime($lastDate);
$dateDiff = $dateTime->diff($lastDateTime);
// Add a new array to the end if the difference between this element and the last was more than a day
if ($dateDiff->days > 1)
$newArray[] = array();
// We can now be guaranteed that the last element of $newArray is the one we want to append to
$newArray[count($newArray) - 1][$date] = $value;
// Keep track of the last date you saw
$lastDate = $date;
}
Here it is in action: https://eval.in/38039
$newArray = array();
$i = 0;
foreach ($array as $date => $key) {
$thisDay = end(explode('-', $date));
$nextDay = end(explode('-', next($array[$date])));
if ($thisDay + 1 != $nextDay + 0)
$i++;
if (!isset($newArray[$i])) {
$newArray[$i] = array($date => $key);
} else {
if (!isset($newArray[$i][$date])) {
$newArray[$i][$date] = $key;
} else {
$newArray[$i][$date] = $key;
}//END IF
}//END IF
}//END FOREACH LOOP
This is the code i would use to do what you are asking.
UPDATE:
I was wrong above. i have altered the code to work this time:
$newArray = array();
$i = 0;
foreach ($array as $date => $key) {
$thisDay = end(explode('-', $date));
$nextDay = array_key_exists(date('Y-m-d', strtotime($date . ' +1 day')), $array);
if (!isset($newArray[$i])) {
$newArray[$i] = array($date => $key);
} else {
if (!isset($newArray[$i][$date])) {
$newArray[$i][$date] = $key;
} else {
$newArray[$i][$date] = $key;
}//END IF
}//END IF
if (!$nextDay)
$i++;
}//END FOREACH LOOP
Here is my test case:
<?php
$array = array(
'2013-07-19' => 1,
'2013-07-21' => 3,
'2013-07-23' => 2,
'2013-07-24' => 4,
'2013-07-25' => 4,
'2013-07-26' => 2,
'2013-07-27' => 2,
'2013-07-30' => 3,
'2013-07-31' => 1
);
echo '<pre>' . print_r($array, true) . '</pre>';
$newArray = array();
$i = 0;
foreach ($array as $date => $key) {
$thisDay = end(explode('-', $date));
$nextDay = array_key_exists(date('Y-m-d', strtotime($date . ' +1 day')), $array);
if (!isset($newArray[$i])) {
$newArray[$i] = array($date => $key);
} else {
if (!isset($newArray[$i][$date])) {
$newArray[$i][$date] = $key;
} else {
$newArray[$i][$date] = $key;
}//END IF
}//END IF
if (!$nextDay)
$i++;
}//END FOREACH LOOP
echo '<pre>' . print_r($newArray, true) . '</pre>';
?>
you can do it like this:
$data = array(
'2013-07-19' => 1,
'2013-07-21' => 3,
'2013-07-23' => 2,
'2013-07-24' => 4,
'2013-07-25' => 4,
'2013-07-26' => 2,
'2013-07-27' => 2,
'2013-07-30' => 3,
'2013-07-31' => 1
);
$result = array();
$ref = new DateTime('1821-11-11');
foreach ($data as $datum => $nb) {
if ($ref->add(new DateInterval('P1D'))->format('Y-m-d')!=$datum) {
$result[] = array();
$ref = new DateTime($datum);
}
$result[array_pop(array_keys($result))][$datum] = $nb;
}
print_r($result);
I am wondering if I could explain this.
I have a multidimensional array , I would like to get the count of particular value appearing in that array
Below I am showing the snippet of array . I am just checking with the profile_type .
So I am trying to display the count of profile_type in the array
EDIT
Sorry I've forgot mention something, not something its the main thing , I need the count of profile_type==p
Array
(
[0] => Array
(
[Driver] => Array
(
[id] => 4
[profile_type] => p
[birthyear] => 1978
[is_elite] => 0
)
)
[1] => Array
(
[Driver] => Array
(
[id] => 4
[profile_type] => d
[birthyear] => 1972
[is_elite] => 1
)
)
)
Easy solution with RecursiveArrayIterator, so you don't have to care about the dimensions:
$iterator = new RecursiveIteratorIterator(new RecursiveArrayIterator($array));
$counter = 0
foreach ($iterator as $key => $value) {
if ($key == 'profile_type' && $value == 'p') {
$counter++;
}
}
echo $counter;
Something like this might work...
$counts = array();
foreach ($array as $key=>$val) {
foreach ($innerArray as $driver=>$arr) {
$counts[] = $arr['profile_type'];
}
}
$solution = array_count_values($counts);
I'd do something like:
$profile = array();
foreach($array as $elem) {
if (isset($elem['Driver']['profile_type'])) {
$profile[$elem['Driver']['profile_type']]++;
} else {
$profile[$elem['Driver']['profile_type']] = 1;
}
}
print_r($profile);
You may also use array_walk($array,"test") and define a function "test" that checks each item of the array for 'type' and calls recursively array_walk($arrayElement,"test") for items of type 'array' , else checks for the condition. If condition satisfies, increment a count.
Hi You can get count of profuke_type==p from a multi dimensiona array
$arr = array();
$arr[0]['Driver']['id'] = 4;
$arr[0]['Driver']['profile_type'] = 'p';
$arr[0]['Driver']['birthyear'] = 1978;
$arr[0]['Driver']['is_elite'] = 0;
$arr[1]['Driver']['id'] = 4;
$arr[1]['Driver']['profile_type'] = 'd';
$arr[1]['Driver']['birthyear'] = 1972;
$arr[1]['Driver']['is_elite'] = 1;
$arr[2]['profile_type'] = 'p';
$result = 0;
get_count($arr, 'profile_type', 'd' , $result);
echo $result;
function get_count($array, $key, $value , &$result){
if(!is_array($array)){
return;
}
if($array[$key] == $value){
$result++;
}
foreach($array AS $arr){
get_count($arr, $key, $value , $result);
}
}
try this..
thanks
Consider following array
$details = array(
array('lname'=>'A', 'fname'=>'P','membkey'=>700,'head'=>'y'),
array('lname'=>'B', 'fname'=>'Q','membkey'=>540,'head'=>'n'),
array('lname'=>'C', 'fname'=>'R','membkey'=>700,'head'=>'n'),
array('lname'=>'D', 'fname'=>'S','membkey'=>540,'head'=>'y'),
array('lname'=>'E', 'fname'=>'T','membkey'=>700,'head'=>'n')
);
Here I would like to sort with head and membkey. Top element of same membkey element should have 'head=y' and echoed as,
$details = array(
array('lname'=>'A', 'fname'=>'P','membkey'=>700,'head'=>'y'),
array('lname'=>'E', 'fname'=>'T','membkey'=>700,'head'=>'n'),
array('lname'=>'C', 'fname'=>'R','membkey'=>700,'head'=>'n'),
array('lname'=>'D', 'fname'=>'S','membkey'=>540,'head'=>'y'),
array('lname'=>'B', 'fname'=>'Q','membkey'=>540,'head'=>'n')
);
I tried it as follows
function orderbymemberKey( $a, $b ){
if ( $a[membkey] == $b[membkey] )
return 0;
return($a[membkey] < $b[membkey] )? -1 :1;
}
usort( $details, orderbymemberKey );
and it successfully order by membkey.
Any suggestions please.
You're half way there (though you were sorting backwards for membkey based on your example):
function order_by_member_key($a, $b)
{
if ($a['membkey'] == $b['membkey'])
{
// membkey is the same, sort by head
if ($a['head'] == $b['head']) return 0;
return $a['head'] == 'y' ? -1 : 1;
}
// sort the higher membkey first:
return $a['membkey'] < $b['membkey'] ? 1 : -1;
}
usort($details, "order_by_member_key");
Is this array being pulled from a database? Because, if so, you should be able to make use of ORDER BY clauses to clean it up outside of php.
<?php
$membkey = array();
$head = array();
foreach ($details as $key => $row) {
$membkey[$key] = $row['membkey'];
$head[$key] = $row['head'];
}
array_multisort($membkey, SORT_DESC, $head, SORT_DESC, $details);
print_r($details);
Or, an even more generic solution:
function sort_by($array) {
$arguments = func_get_args();
$array = array_pop($arguments);
$variables = array();
foreach ($arguments as $index => $key) {
$variables[] = '$arguments['.$index.']';
if ($index % 2 == 0) {
$arguments[$index] = array();
foreach ($array as $row) $arguments[$index][] = $row[$key];
}
}
// call_user_func_array will not work in this case
eval('array_multisort('.implode(', ', $variables).', $array);');
return $array;
}
print_r(sort_by('membkey', SORT_DESC, 'head', SORT_DESC, $details));
Ugly but someone wrote a function on php.net:
http://php.net/manual/en/function.sort.php
<?php
$array[0]['name'] = 'Chris';
$array[0]['phone'] = '3971095';
$array[0]['year'] = '1978';
$array[0]['address'] = 'Street 1';
$array[1]['name'] = 'Breanne';
$array[1]['phone'] = '3766350';
$array[1]['year'] = '1990';
$array[1]['address'] = 'Street 2';
$array[2]['name'] = 'Dusty';
$array[2]['phone'] = '1541120';
$array[2]['year'] = '1982';
$array[2]['address'] = 'Street 3';
function multisort($array, $sort_by, $key1, $key2=NULL, $key3=NULL, $key4=NULL, $key5=NULL, $key6=NULL){
// sort by ?
foreach ($array as $pos => $val)
$tmp_array[$pos] = $val[$sort_by];
asort($tmp_array);
// display however you want
foreach ($tmp_array as $pos => $val){
$return_array[$pos][$sort_by] = $array[$pos][$sort_by];
$return_array[$pos][$key1] = $array[$pos][$key1];
if (isset($key2)){
$return_array[$pos][$key2] = $array[$pos][$key2];
}
if (isset($key3)){
$return_array[$pos][$key3] = $array[$pos][$key3];
}
if (isset($key4)){
$return_array[$pos][$key4] = $array[$pos][$key4];
}
if (isset($key5)){
$return_array[$pos][$key5] = $array[$pos][$key5];
}
if (isset($key6)){
$return_array[$pos][$key6] = $array[$pos][$key6];
}
}
return $return_array;
}
//usage (only enter the keys you want sorted):
$sorted = multisort($array,'year','name','phone','address');
print_r($sorted);
//output:
