php delete specific value from array

Question

I have an array $products that looks like this

Array
(
 [services] => Array
 (
 [0] => Array
 (
 [id] => 1
 [icon] => bus.png
 [name] => Web Development
 [cost] => 500
 )
 [1] => Array
 (
 [id] => 4
 [icon] => icon.png
 [name] => Icon design
 [cost] => 300
 )
 )
)

I am trying to delete the part of array that matches [id] => 1 and for this I am using the following code

$key = array_search('1', $products);
unset($products['services'][$key]);

However it is not working and I am not getting any error either. What am i doing wrong?

• edwardmp: Do you only want to delete [id] => 1 from that subarray, or the whole parent array (with key 0 in this case) ?
• gskema: foreach is the way to go
• Shairyar: @edwardmp I would like to delete the whole parent array (with key 0 in this case)

Answer 1

This should work for you:

$key = array_search('1', $products["services"]);
 //^^^^^^^^^^^^ See here i search in this array
unset($products['services'][$key]);
print_r($products);

Output:

Array ( [services] => Array ( [1] => Array ( [id] => 4 [icon] => icon.png [name] => Icon design [cost] => 300 ) ) )

And if you want to reindex the array, so that it starts again with 0 you can do this:

$products["services"] = array_values($products["services"]);

Then you get the output:

Array ( [services] => Array ( [0] => Array ( [id] => 4 [icon] => icon.png [name] => Icon design [cost] => 300 ) ) )
 //^^^ See here starts again with 0

Answer 2

This will loop through $products['services'] and delete the array whose 'id' key has value 1. array_values just re-indexes the array from 0 again.

foreach($products['services'] as $key => $service)
{
 if($product['id'] == 1)
 {
 unset($products['services'][$key]);
 array_values($products['services']);
 break;
 }
}
