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?

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; } }
