I want to convert a stdClass object to string and reduce an array with the max value from the stdClass object.
This is my array:
Array
(
[135] => Array
(
[0] => stdClass Object
(
[ID] => 145
)
[1] => stdClass Object
(
[ID] => 138
)
[2] => stdClass Object
(
[ID] => 139
)
)
[140] => Array
(
[0] => stdClass Object
(
[ID] => 163
)
[1] => stdClass Object
(
[ID] => 155
)
)
Basically it should look like this:
Array
(
[135] => 139
[140] => 164
)
Is this possible? I've tried various foreach loops but i don't get it with the stdClass object...
My try so far:
foreach($ids as $k => $v) {
for($i = 0; $i < count($v); $i++) {
$idss[$i] = array()$v;
}
}
That doesn't work.
This will solve your purpose. let me know if anything goes wrong.
$ids[135][0]->ID = 145;
$ids[135][1]->ID = 135;
$ids[135][2]->ID = 155;
$ids[140][0]->ID = 125;
$ids[140][1]->ID = 135;
$idss = array();
foreach($ids as $k => $v) {
for($i = 0; $i < count($v); $i++) {
if(!#$idss[$k] || $v[$i]->ID > $idss[$k])
{
$idss[$k] = $v[$i]->ID;
}
}
}
echo "<Pre>";
print_r($idss);
die;
Already answered but here is a shorter version of this
$final_array =array();
foreach($arr as $key=>$val){
$max = max(array_keys($val));
$final_array[$key] = $val[$max]->ID ;
}
print_r($final_array);
Here $arr is your input array.
You need to do some compariosn in your inner for loop to know which one holds the max value. Here is an example :
$new_arr = array();
foreach($elements as $index => $value){
$max = -1;
$foreach($value as $obj){
if($obj->id > $max)
$max = $obj->id;
}
$new_arr [$index] = $max;
}

I have an Array Array
( [0] => ["1","2","7","8","9"] )
and i want to like that
Array ( [0] => 1 [1] => 2 [2] => 7 [3] => 8 [4] => 9 )
i try foreach loop
foreach($no_a as $key=>$val){
foreach($val as $k=>$v){
$newp_arr[] $v ;
}
}
$result = $no_a[0];
$new_result = array();
for ($i=0; $i < 21 ; $i++) {
# code...
$num = $result[$i];
if(is_numeric($num))
{
$new_result[] = $result[$i];
}
}
print_r($new_result);
I have following associative array:
Array
(
[0] => Array
(
[0] => 268
)
[1] => Array
(
[0] => 125
[1] => 258
[2] => 658
[3] => 128
[4] => 987
)
[2] => Array
(
[0] => 123
[1] => 258
)
[3] => Array
(
[0] => 168
)
)
I need the following result as string.
268
125258658128987
123258
168
What I have tried so far;
<?php
//consider my array is in $array variable
for ($i = 0; $i < count($array); $i++)
{
foreach ($array[$i] as $res)
{
echo $res . '<br/>';
}
}
?>
But unfortunately I am getting each numbers in a new line.
Any suggestion will be appreciated.
You have to echo the <br /> outside the foreach loop:
for ($i = 0; $i < count($array); $i++)
{
foreach ($array[$i] as $res) {
echo $res;
}
echo '<br />'; //<-- Put this outside the foreach loop
}
Or another option, you can use foreach and implode for a simpler approach
foreach ($array as $value)
{
echo implode('',$value);
echo '<br />';
}

i have two arrays
$value_array = array('50','40','30','20','10');
$customer = array('300','200','100');
i want to distribute the value array to customers based on the value of customers that is taken as limit.adding values by checking it wont cross the limit that is 300 , 200 and 100.
but customer array not working one direction it should work first forward and then backward like that
i want to produce an array in form of
Array
(
[0] => Array
(
[0] => 50
)
[1] => Array
(
[0] => 40
[1] => 10
)
[2] => Array
(
[0] => 30
[1] => 20
)
)
After completing customer loop first time it should start from last to first. both array count will change , i mean count.
value array should check 50 -> 300 , 40->200, 30->100 then from last ie, 20 ->100, 10->200 etc.
I tried like
$i = 0;
while($i < count($customer)){
foreach($value_array as $k=>$value){
$v = 0;
if($value <= $customer[$i]){
$customer2[$i][] = $value;
unset($value_array[$k]);
$v = 1;
}
if($v ==1){
break;
}
}
//echo $i."<br/>";
if($i == (count($customer)-1) && (!empty($value_array))){
$i = 0;
$customer = array_reverse($customer, true);
}
$i++;
}
echo "<pre>";
print_r($customer2);
$valueArray = array('50','40','30','20','10','0','-11');
$customer = array('300','200','100');
function parse(array $valueArr, array $customerArr)
{
$customerCount = count($customerArr);
$chunkedValueArr = array_chunk($valueArr, $customerCount);
$temp = array_fill(0, $customerCount, array());
$i = 0;
foreach ($chunkedValueArr as $item) {
foreach ($item as $key => $value) {
$temp[$key][] = $value;
}
$temp = rotateArray($temp);
$i++;
}
// if $i is odd
if ($i & 1) {
$temp = rotateArray($temp);
}
return $temp;
}
function rotateArray(array $arr)
{
$rotatedArr = array();
//set the pointer to the last element and add it to the second array
array_push($rotatedArr, end($arr));
//while we have items, get the previous item and add it to the second array
for($i=0; $i<sizeof($arr)-1; $i++){
array_push($rotatedArr, prev($arr));
}
return $rotatedArr;
}
print_r(parse($valueArray, $customer));
returns:
Array
(
[0] => Array
(
[0] => 50
[1] => 0
[2] => -11
)
[1] => Array
(
[0] => 40
[1] => 10
)
[2] => Array
(
[0] => 30
[1] => 20
)
)
Problem
I have an array which is returned from PHPExcel via the following
<?php
require_once 'PHPExcel/Classes/PHPExcel/IOFactory.php';
$excelFile = "excel/1240.xlsx";
$objReader = PHPExcel_IOFactory::createReader('Excel2007');
$objPHPExcel = $objReader->load($excelFile);
foreach ($objPHPExcel->getWorksheetIterator() as $worksheet) {
$arrayData[$worksheet->getTitle()] = $worksheet->toArray();
}
print_r($arrayData);
?>
This returns:
Array
(
[Films] => Array
(
[0] => Array
(
[0] => Name
[1] => Rating
)
[1] => Array
(
[0] => Shawshank Redemption
[1] => 39
)
[2] => Array
(
[0] => A Clockwork Orange
[1] => 39
)
)
[Games] => Array
(
[0] => Array
(
[0] => Name
[1] => Rating
)
[1] => Array
(
[0] => F.E.A.R
[1] => 4
)
[2] => Array
(
[0] => World of Warcraft
[1] => 6
)
)
)
What I would like to have is
Array
(
[Films] => Array
(
[0] => Array
(
[Name] => Shawshank Redemption
[Rating] => 39
)
[1] => Array
(
[Name] => A Clockwork Orange
[Rating] => 39
)
)
[Games] => Array
(
[0] => Array
(
[Name] => F.E.A.R
[Rating] => 4
)
[1] => Array
(
[Name] => World of Warcraft
[Rating] => 6
)
)
)
The arrays names (Films, Games) are taken from the sheet name so the amount can be variable. The first sub-array will always contain the key names e.g. Films[0] and Games[0] and the amount of these can be varible. I (think I) know I will need to do something like below but I'm at a loss.
foreach ($arrayData as $value) {
foreach ($value as $rowKey => $rowValue) {
for ($i=0; $i <count($value) ; $i++) {
# code to add NAME[n] as keys
}
}
}
I have searched extensively here and else where if it is a duplicate I will remove it.
Thanks for any input
Try
$result= array();
foreach($arr as $key=>$value){
$keys = array_slice($value,0,1);
$values = array_slice($value,1);
foreach($values as $val){
$result[$key][] = array_combine($keys[0],$val);
}
}
See demo here
You may use nested array_map calls. Somehow like this:
$result = array_map(
function ($subarr) {
$names = array_shift($subarr);
return array_map(
function ($el) use ($names) {
return array_combine($names, $el);
},
$subarr
);
},
$array
);
Demo
Something like this should work:
$newArray = array();
foreach ($arrayData as $section => $list) {
$newArray[$section] = array();
$count = count($list);
for ($x = 1; $x < $count; $x++) {
$newArray[$section][] = array_combine($list[0], $list[$x]);
}
}
unset($arrayData, $section, $x);

Probably a little late answer, but it looks more like your tried solution
//Films,Games // Row Data
foreach ($arrayData as $type => $value)
{
$key1 = $value[0][0]; // Get the Name Key
$key2 = $value[0][1]; // Get the Rating Key
$count = count($value) - 1;
for ($i = 0; $i < $count; $i++)
{
/* Get the values from the i+1 row and put it in the ith row, with a set key */
$arrayData[$type][$i] = array(
$key1 => $value[$i + 1][0],
$key2 => $value[$i + 1][1],
);
}
unset($arrayData[$type][$count]); // Unset the last row since this will be repeated data
}
I think this will do:
foreach($arrayData as $key => $array){
for($i=0; $i<count($array[0]); $i++){
$indexes[$i]=$array[0][$i];
}
for($i=1; $i<count($array); $i++){
for($j=0; $j<count($array[$i]); $j++){
$temp_array[$indexes[$j]]=$array[$i][$j];
}
$new_array[$key][]=$temp_array;
}
}
print_r($new_array);
EDIT: tested and updated the code, works...
I have the following issue, I have an array with the name $data
Within this array I have something like
[6] => Array
(
[code] => 642
[total] => 1708
)
[7] => Array
(
[code] => 642
[total] => 53
)
[8] => Array
(
[code] => 642
[total] => 1421
)
In some elements the code value is the same, now what I want to do is merge all the elements with the same code value together, and adding the totals together. I tried doing this in a foreach loop, but does not seem to work.
I do something like this
$old_lc = null;
$old_lcv = 0;
$count = 0;
$dd = null;
foreach($data as $d){
if($d['code'] == $old_lc){
$d['total'] = $d['total'] + $old_lcv;
$count--;
$dd[$count]['code'] = $d['code'];
$dd[$count]['total'] = $d['total'];
}else{
$dd[$count]['code'] = $d['code'];
$dd[$count]['total'] = $d['total'];
$count++;
}
$old_lc = $d['code'];
$old_lcv = $d['total'];
}
$data = $dd;
But this does not seem to work. Also I need the $data array to keep the keys, and should remain in the same format
$result = array();
foreach($ary as $elem) {
$code = $elem['code'];
$total = $elem['total'];
if(!isset($result[$code]))
$result[$code] = 0;
$result[$code] += $total;
}
This code translates the above array into an array of code => total.
$out = array();
foreach ($data as $k => $v) {
$out[$v['code']] += $v['total'];
}
It is worth noting that on certain settings this will generate a warning about undefined indexes. If this bothers you, you can use this alternate version:
$out = array();
foreach ($data as $k => $v) {
if (array_key_exists($v['code'], $out)) {
$out[$v['code']] += $v['total'];
} else {
$out[$v['code']] = $v['code'];
}
}
This turns it back into something like the original, if that's what you want:
$output = array();
foreach ($out as $code => $total) {
$output[] = array('code' => $code, 'total' => $total);
}
Note: the original keys of $data aren't maintained but it wasn't stated that this was a requirement. If it is, it needs to be specified how to reconstruct multiple elements that have the same code.

[code] => 642

$data_rec = array();
$data = array();
foreach($data_rec as $key=>$rec)
{
$data[$key]+= $rec[$key];
}
print_r($data);
