PHP merge duplicate key in array - php

Question

i got response (json) from web service and converted / decoded it into php array.
converted array php:
$data = [
[
'id' => '01',
'name' => 'ABC',
'label' => 'color',
'value' => '#000000'
],[
'id' => '01',
'name' => 'ABC',
'label' => 'active',
'value' => true
],[
'id' => '02',
'name' => 'DEF',
'label' => 'color',
'value' => '#ffffff'
],[
'id' => '02',
'name' => 'DEF',
'label' => 'active',
'value' => false
]
];
expected array output:
$data = [
[
'id' => '01',
'name' => 'ABC',
'color' => '#000000',
'active' => true,
],[
'id' => '02',
'name' => 'DEF',
'color' => '#ffffff',
'value' => false
]
];
What php function is suitable for that case? thanks in advance

Answer 1

You can simple use foreach
$r = [];
foreach($data as $v){
if(isset($r[$v['id']])){
$r[$v['id']][$v['label']] = $v['value'];
}else{
$r[$v['id']] = [
'id' => $v['id'],
'name' => $v['name'],
$v['label'] => $v['value']
];
}
}

Answer 2

$data = json_decode($data); //decode the json into a php array
foreach ($data as $key=>$subArray){ //loop over the array
//check and see if value is either true/false
if (is_bool($subArray['value'])){
$processedArray[] = $subArray; //build output
}
}
print_r($processedArray); //output/dump array for debugging

Answer 3

In this case, you have to loop through the array and remove duplicates, Try the given way
$data = json_decode($data , true);
$filtered = array();
for($i = 0 ; $i < count($data) ; $i++){
if(!array_key_exist($data[$i]['id'] , $filtered )){
$filtered [$data[$i]['id']] = $data[$i];
continue;
}
}
$filtered = array_values($filtered);
