I have an array of objects.
What I need is to take each [name] of each object in put into another array, but I don't want duplicates.
How can I do it?
Array (
[0] => ADOFetchObj Object
(
[name] => Team 1
[att] => None
[idGrupo] => 1
[idModulo] => 4
[ler] => 1
[escrever] => 1
[excluir] => 1
)
[1] => ADOFetchObj Object
(
[name] => Team 1
[nomeModulo] => Aplicar Juros
[idGrupo] => 1
[idModulo] => 1006
[ler] => 1
[escrever] => 1
[excluir] => 1
)
[2] => ADOFetchObj Object
(
[name] => Team 2
[att] => None
[idGrupo] => 1
[idModulo] => 10
[ler] => 1
[escrever] => 1
[excluir] => 1
)
[3] => ADOFetchObj Object
(
[name] => Team 2
[att] => None
[idGrupo] => 1
[idModulo] => 1012
[ler] => 1
[escrever] => 1
[excluir] => 1
)
)
Thanks!
You can do this:
$names = array();
foreach($arr as $list) {
$names[$list->name] = true; // can be *any* arbitrary value
}
$names = array_keys($names);
This will work because by definition array keys have to be unique.
array_unique(array_map(function($element) {
return $element->name;
}, $my_array));
There you go
$res = array();
foreach($arr as $var)
{
if(!in_array($var->name, $res))
{
$res[] = $var->name;
}
}
First, copy the names to a new array:
$arrNames = array();
foreach($arrOriginal as $objObject) {
array_push(
$arrNames,
$objObject->name
);
}
Then remove the duplicate names:
$arrNames = array_unique($arrNames);
$n = array();
foreach($array as $d) $n[] = $d->name;
$n = array_unique($n);

I want to merge those elements which has same hrg_lid.
Expected Output
Array

(
[hrg_lid] => 214291464161204318
[pecon] => 0

)
I tried following code
foreach($arr as $key => $value) {
$finalArray[$value['hrg_lid']] = $value;
}
but fails
I would use hrg_lid as array key - otherwise you have to check every element already in the output array for matches every time you add a new element:
$finalArray = array();
foreach($arr as $value) {
$hrg_lid = $value['hrg_lid'];
if (isset($finalArray[$hrg_lid])) {
// merge if element with this $hrg_lid is already present
$finalArray[$hrg_lid] = array_merge($finalArray[$hrg_lid], $value);
} else {
// save as new
$finalArray[$hrg_lid] = $value;
}
}
If you want to get normalized array keys, you can reset them afterwards:
$finalArray = array_values($finalArray);
The hrg_lid value must be the key of the array, if you won't change the keys, Try this :
for($i=0; $i < count($arr);$i++)
{
for($j=0; $j < count($finalArray);$j++)
{
if($arr[$i]['hrg_lid'] == $finalArray[$j]['hrg_lid'])
{
$finalArray[$j] = array_merge($finalArray[$j],$arr[$i]);
break;
}
}
}
Try soomething like :
$finalArray = [];
foreach($arr as $singleArray) {
$id = $singleArray['hrg_lid'];
if (isset($finalArray[$id])) {
$finalArray = array_merge($finalArray[$id], $singleArray);
} else {
$finalArray[] = $singleArray;
}
}
You could try something like that :
$tmpArray = array();
$finalArray = array();
// We merge the arrays which have the same value in 'hrg_lid' col
foreach($source as $array){
$key = $array['hrg_lid'];
array_shift($array);
if(array_key_exists($key, $tmpArray)){
$tmpArray[$key] = array_merge($tmpArray[$key], $array);
}else{
$tmpArray[$key] = $array;
}
}
// We build the final array
foreach($tmpArray as $key => $value){
$finalArray[] = array_merge(array('hrg_lid' => $key), $value);
}
I need to display a certain object from an array before showing the rest of the array.
The array looks like this:
Array
(
[0] => stdClass Object
(
[template_id] => 91
[template_name] => Alphabet
[template_thumbnail] => blank-template-thumbnail.jpg
[template_create_date] => 1456821665
[template_customer_id] => 0
[template_is_responsive] => no
[template_type] => builder
[template_category] => simple
[sort] => 2
)
[1] => stdClass Object
(
[template_id] => 92
[template_name] => Blank Template
[template_thumbnail] => blank-template-thumbnail.jpg
[template_create_date] => 1456821670
[template_customer_id] => 0
[template_is_responsive] => no
[template_type] => builder
[template_category] => simple
[sort] => 2
)
[2] => stdClass Object
(
[template_id] => 31
[template_name] => Holiday Specials
[template_thumbnail] => accommodation-1-20110926.jpg
[template_create_date] => 1456821660
[template_customer_id] => 0
[template_is_responsive] => no
[template_type] => builder
[template_category] => Accommodation
[sort] => 3
)
)
I need to show Blank Template first and then show the rest alphabetically (the order it is in now.
Is there a more elegant solution than looping through the array twice? The size of the array can be anything from 1 (the blank template) to countless objects.
$str="";
for($i=0;$i<=count($arr);$i++){
if($arr[$i]['template_name'] == "Blank Template"){
echo $arr[$i]['template_name'];
}else{
$str .= $arr[$i]['template_name']. "<br>";
}
}
echo $str;
Try this:
$firstItem = null;
$outArray = [];
foreach($yourArray as $item){
if($item->template_name == 'Blank Template'){
$firstItem = $item;
}else{
$outArray[$item->template_name] = $item;
}
}
ksort($outArray,SORT_STRING);
array_unshift($outArray,$firstItem);
Just one loop. Pay attention that this way of doing things, just work if you have uniqueness on the template_name!
Hope it helps.
This will work for you, try
<?php
$dataArray = array(0=>array('template_id'=>91,'template_name'=>'Alphabet'),
1=>array('template_id'=>92,'template_name'=>'Blank Template'),
2=>array('template_id'=>31,'template_name'=>'Holiday Specials')
);
$newArray = array();
foreach($dataArray as $key => $val)
{
if(in_array('Blank Template',$val))///find the key for black template
{
unset($dataArray[$key]); ///unset black temp from original array
$newArray[] = $val;///push black temp into new array at 0 index
foreach($dataArray as $k => $v)
{
$newArray[] = $v; ///push the renaming values into new array
}
}
}
echo "<pre>"; print_r($newArray);
?>
This will give you :
Array
(
[0] => Array
(
[template_id] => 92
[template_name] => Blank Template
)
[1] => Array
(
[template_id] => 91
[template_name] => Alphabet
)
[2] => Array
(
[template_id] => 31
[template_name] => Holiday Specials
)
)

I am working in multidimensional array, i have an array like this and i want to merge array
[0] => Array
(
[QuizId] => 173
[QuizName] => Reprocessing Surgical Drapes and Gowns
[totalexams] => 1
[UserScore] => 8
[MaxScore] => 20
[passed] => 1
[CategoryId] => 1
[CategoryName] => CRCST
[totalTimes] => 1
[orderId] => 19
[productId] => 50
)
[1] => Array
(
[QuizId] => 173
[QuizName] => Reprocessing Surgical Drapes and Gowns
[totalexams] => 1
[UserScore] => 8
[MaxScore] => 20
[passed] => 1
[CategoryId] => 1
[CategoryName] => CRCST
[totalTimes] => 1
[orderId] => 20
[productId] => 50
)
All i need is to make array by join orderId 19,20
ie,
[0] => Array
(
[QuizId] => 173
[QuizName] => Reprocessing Surgical Drapes and Gowns
[totalexams] => 1
[UserScore] => 8
[MaxScore] => 20
[passed] => 1
[CategoryId] => 1
[CategoryName] => CRCST
[totalTimes] => 1
[orderId] => 19,20
[productId] => 50
)
I want to arrange like this.please help me to achieve this
You can try something like this
//This is your old array that you describe in your first code sample
$old_array = array();
// This will be the new joined array
$new = array();
// This will hold the key-pairs for each array within your initial array
$temp = array();
// This will hold all the values of orderId
$orderId = array();
// Loop through each first-level array with the original array
foreach($old_array as $val) {
//Loop through each second-level array
foreach($val as $key => $value) {
// Set the key-pair values in the $temp array
$temp[$key] = $temp[$value];
if($key == "orderId") {
// Add the current orderId value to the orderId array
array_push($orderId,$value);
// Join all the orderId values into the $temp array
$temp[$key] = join(",", $orderId);
}
}
}
//Push the final values to the new array to get a 2 dimensional array
array_push($new, $temp);
Note: I did not test any of the following code so it is very likely to not work at first.
This is also VERY bad array design and there are more likely easier and more practical solutions to this problem, but you will need to give more details on what you want to achieve
$original_array = array(); //this is the array you presented
$new_array = array(); //this is the output array
foreach($original_array as $arr) {
foreach($arr as $key => $value) {
if(array_key_exists($key, $new_array)) { //if you already assigned this key, just concat
$new_array[0][$key] .= "," . $value;
} else { //otherwise assign it to the new array
$new_array[0][$key] = $value;
}
}
}
It will give you the desired result
$arrNew = array();
$i = 0;
foreach($multiDArray as $array)
{
foreach($array as $key=>$value)
{
if($i > 0)
{
if($arrNew[$key] != $value)
{
$str = $arrNew[$key].','.$value;
$arrNew[$key] = $str;
}
}
else
{
$arrNew[$key] = $value;
}
}
$i++;
}
print_r($arrNew);
Result:
Array
(
[QuizId] => 173
[QuizName] => Reprocessing Surgical Drapes and Gowns
[totalexams] => 1
[UserScore] => 8
[MaxScore] => 20

i have a (dynamic) array, which in this example contains 4 sets of data (5 fields per set), but it could be only one set or up to 25 sets.
Array ( [lightwattage1] => 50 [lightvoltage1] => 12 [lightquantity1] => 2 [lightusage1] => 4 [lightcomment1] => [lightwattage2] => 60 [lightvoltage2] => 24 [lightquantity2] => 4 [lightusage2] => 5 [lightcomment2] => [lightwattage3] => 30 [lightvoltage3] => 240 [lightquantity3] => 4 [lightusage3] => 2 [lightcomment3] => [lightwattage4] => 25 [lightvoltage4] => 12 [lightquantity4] => 2 [lightusage4] => 6 [lightcomment4] => )
which i'd like to turn into something like
Array ( Array ( [lightwattage1] => 50 [lightvoltage1] => 12 [lightquantity1] => 2 [lightusage1] => 4 [lightcomment1] => ),
Array ( [lightwattage2] => 60 [lightvoltage2] => 24 [lightquantity2] => 4 [lightusage2] => 5 [lightcomment2] => ),
Array ( [lightwattage3] => 30 [lightvoltage3] => 240 [lightquantity3] => 4 [lightusage3] => 2 [lightcomment3] => ),
Array ( [lightwattage4] => 25 [lightvoltage4] => 12 [lightquantity4] => 2 [lightusage4] => 6 [lightcomment4] => )
)
the original array is created this way:
$light = Array();
foreach( $_POST as $key => $val )
{
//field names that start with light to go in this array
if (strpos($key, 'light') === 0) {
$light[$key] = $val;
}
}
the field name digit is already added with JS before form submission, and not by php script.
any hint much appreciated.
This is not an exacty answer to you question, but...
You can use arrays in POST variables like so:
<input name="light[1][wattage]" />
<input name="light[1][voltage]" />
<input name="light[2][wattage]" />
<input name="light[2][voltage]" />
will give you:
$_POST['light'] == array(
1 => array(
'wattage' => '...',
'voltage' => '...',
),
2 => array(
'wattage' => '...',
'voltage' => '...',
),
)
Try this:
$prefixes = array();
$postfixes = array();
foreach($original_array as $key=>$value)
{
preg_match('/^([^\d]*)(\d+)$/',$key,$matches);
if(count($matches)>1)
{
if(!in_array($matches[1], $prefixes)) $prefixes[] = $matches[1];
if(!in_array($matches[2], $postfixes)) $postfixes[] = $matches[2];
}
}
$new_array = array();
foreach($postfixes as $postfix)
{
$new_element = array();
foreach($prefixes as $prefix)
{
if(isset($original_array[$prefix.$postfix])) $new_element[$prefix.$postfix] = $original_array[$prefix.$postfix];
}
$new_array[] = $new_element;
}
given an $original_array equal to described, will produce $new_array:
Array
(
[0] => Array
(
[lightwattage1] => 50
[lightvoltage1] => 12
[lightquantity1] => 2
[lightusage1] => 4
[lightcomment1] =>
)
[1] => Array
(
[lightwattage2] => 60
[lightvoltage2] => 24
[lightquantity2] => 4
[lightusage2] => 5
[lightcomment2] =>
)
[2] => Array
(
[lightwattage3] => 30
[lightvoltage3] => 240
[lightquantity3] => 4
[lightusage3] => 2
[lightcomment3] =>
)
[3] => Array
(
[lightwattage4] => 25
[lightvoltage4] => 12
[lightquantity4] => 2
[lightusage4] => 6
[lightcomment4] =>
)
)
I was uncertain about how much you knew about the elements or their order, so this code basically takes any collection of elements that end in numbers and rearranges them in groups that have the same ending number.
Try this:
$outarr = array()
$subarr = array()
$i=0;
foreach($_POST as $key => $val)
{
//only include keys starting with light:
if (strpos("light", $key)==0)
{
//create a new subarray each time we find a key that starts with "lightwattage":
if ($i>0 && strpos("lightwattage", $key)==0)
{
$outarr[] = $subarr;
}
$subarr[$key] = $val;
$i++;
}
}
$outarr[] = $subarr;
//$outarr contains what you want here
I have this array:
Array (
[061716v] => 1
[061610A] => 1
[062433AP] => 1
[063868M] => 2
[059173V] => 3
[061579A] => 3
[062404AP] => 3
[059179V] => 4
[061582A] => 4
[061697V] => 4
[062407AP] => 4
)
How can i get this:
Array (
[1] => 061716v,061610A,062433AP
[2] => 063868M
[3] => 059173V,061579A,062404AP
[4] => 059179V,061582A,061697V,062407AP
)
In PHP single foreach() will do the job:-
$final_array = [];
foreach($initial_array as $key=>$val){
$final_array[$val] = isset($final_array[$val]) ? $final_array[$val].','.$key : $key;
}
print_r($final_array);
Output:-https://3v4l.org/lSKE2
// You also can use implode to skip isset checks
$group = [];
foreach ($initialArray as $key => $value) {
$group[$value][] = $key;
}
$result = array_map(function($v) { return implode(",",$v); }, $group);
print_r($result);
