This is assuming both name/value are strings
<?php
$objects; // This is your array
$sorted = array(); // This is the sorted array
// Loop over your array
foreach($objects as $object)
{
// Check if object exists in sorted array
if( array_key_exists($object->name, $sorted) )
{
// Object with this name is already in sorted array simply add to it
$obj = $sorted[$object->name];
// Update the values
$obj->value = $obj->value . ',' . $object->value;
} else {
// Object is not in the sorted array add it now
$sorted[$object->name] = $object;
}
}
?>

Sorry, your case is not ordinary, so you will need to do it by hand
$properArray = array();
foreach ($originArray as $value) {
if ( ! isset($properArray[$value['name']])) {
$properArray[$value['name']] = array(
'name' = $value['name'],
'value' = ''
);
}
if (isset($properArray[$value['name']]['value'])) {
$properArray[$value['name']]['value'] = $properArray[$value['name']]['value'] . ',' .$value['value']; //better to use array in this place
} else {
$properArray[$value['name']]['value'] = $value['value']
}
}
$originArray = array_values($properArray);
regards,

You have an array of object. You will have to loop through and assign them. Something like
$newArray = [];
foreach ($array as $obj) {
if (!isset($newArray[$obj->name])) {
$newArray[$obj->name] = $obj;
} else {
$newArray[$obj->name]->value .= ",{$obj->value}";
}
}
The new array should look like
["wpc_inline_chkbox[]"] => stdClass Object
(
[name] => wpc_inline_chkbox[]
[value] => "1,2,3"
)
But you should change [value] from string to array.

## Use this ##
$arr = array(
array(
'name' => 'hi'
,'value' => 1
)
,array(
'name' => 'hi'
,'value' => 2
)
, array(
'name' => 'hi2'
,'value' => 1
)
, array(
'name' => 'hi4'
,'value' => 1
)
,array(
'name' => 'hi0'
,'value' => 4
)
, array(
'name' => 'hi0'
,'value' => 3
)
, array(
'name' => 'hi1'
,'value' => 10
)
);
print_r($arr);
$arrTracker = array();
for ($i=0; $i <sizeof($arr) ;$i++) {
for($j = $i+1; $j<sizeof($arr);$j++){
if($arr[$i]['name'] == $arr[$j]['name']){
$arr[$i]['value'] .= ','.$arr[$j]['value'];
$arrTracker[$j] = $j;
}
}
}
// if you want to unset duplicate name and corresponding value, use below forloop, otherwise it's unnecessary
foreach($arrTracker as $tracker){
unset($arr[$tracker]);
}
$arr = array_values($arr);
print_r($arr);
