Taking out just one value from an array - php

Question

I have an array which is
Array ( [0] => Array ( [picture] => 5a55ed8d8a5c8910913.jpeg
[id] => 1284
[price_range] => Rs 12000 - 9000
[name] => Brown Beauty Office Chair )
[1] => Array ( [picture] => 5a55eefeb9a8e255836.jpeg
[id] => 1285
[price_range] => Rs 8989 - 7000
[name] => Chang Series Office Chair (Grey)
)
)
Now I am fetching the value of id on clicking a remove button, the value I fetch is 1284.
I want to take out just [id]=> 1284 from the above array and then display it using a foreach loop. How I can delete just the [id]=> 1284 without disturbing the other id values and other element.
In the above array I would like to delete one particular id value say just the [id]=> 1284 and keep all other elements intact and as it is.
Any help is welcome.

Answer 1

Use array_search and array_column, to find by id and remove by unset method,
<?php
$array = [
["id"=>123,"desc"=>"test1"],
["id"=>456,"desc"=>"test2"],
["id"=>789,"desc"=>"test3"],
];
$id = 456;
$index = array_search($id, array_column($array, 'id'));
unset($array[$index]);
print_r($array);
?>

)

Since you asked how to achieve it using foreach, I came up with this.
$array = Array (Array ( 'picture' => '5a55ed8d8a5c8910913.jpeg','id' => 1284,'price_range' => 'Rs 12000 - 9000', 'name' => 'Brown Beauty Office Chair'),
Array ( 'picture' => '5a55eefeb9a8e255836.jpeg','id' => 1285,'price_range' => 'Rs 8989 - 7000','name' => 'Chang Series Office Chair (Grey)')
);
foreach($array as $key => $val) {
$id = $array[$key]['id'];
if($id === 1284){
unset($array[$key]['id']);
}
}
print_r($array)
?>

You can also use this too:
<?php
$element_to_remove = 1284;
$i = 0;
foreach($array as $this_arr){
$index = array_search($element_to_remove, $this_arr);
//unset($this_arr[$index]); this formate does not remove element from array
//but below works fine
if(isset($array[$i][$index])){
unset($array[$i][$index]);
}
}
print_r($array);
?>
