how to modify array that each item is array in php (clarify in description)

Question

i had a array to each its item was object , i've converted that array with following code :

json_decode(json_encode($array), true)

that the result of code was a array like this :

[
  '1'=>[
   'slug'=>'a'
   'title'=>'foo' 
  ],
  '2'=>[
   'slug'=>'b'
   'title'=>'bar' 
  ],
  '3'=>[
   'slug'=>'c'
   'title'=>'foo' 
  ],
]

now i want to covert this array to somethings like this

 [
   'a'=>'foom',
   'b'=>'bar',
   'c'=>'foo',
 ]

how can i do it ??

Use foreach and array_combine()

foreach ($your_array as $key => $value) {
  // get all the keys in $slug array
  $slug[] = $value['slug'];
  // get all the values in $title array
  $title[] = $value['title'];
}
// finally combine and get your required array
$required_array = array_combine($slug, $title);

I think it can also be acheived with -

$requiredArray = array_combine(
   array_column($your_array, 'slug'), 
   array_column($your_array, 'title')
);

You have to iterate over the initial array and create the new one like this:

$array = [
  '1'=>[
   'slug'=>'a'
   'title'=>'foo' 
  ],
  '2'=>[
   'slug'=>'b'
   'title'=>'bar' 
  ],
  '3'=>[
   'slug'=>'c'
   'title'=>'foo' 
  ],
];

$result = [];
foreach($array as $elem){
   $index = $elem["slug"];
   $value= $elem["title"];
   $result[$index] = $value; 
}

foreach($array as $elem){
    $result[$elem["slug"]] = $elem["title"]; 
}
