If you know the keys of the elements which you want to delete, then you want to use \array_diff_key(). As before with unset() it won’t change the keys of the array. If you know the values of the array elements which you want to delete, then you can use \array_diff(). If you want to delete multiple array elements and don’t want to call unset() or \array_splice() multiple times you can use the functions \array_diff() or \array_diff_key() depending on whether you know the values or the keys of the elements which you want to delete. You don’t assign the return values of those functions back to the array. \array_splice() needs the offset, not the key, as the second parameter.Īrray_splice(), same as unset(), take the array by reference. If you use \array_splice() the keys will automatically be reindexed, but the associative keys won’t change - as opposed to \array_values(), which will convert all keys to numerical keys. If you want to reindex the keys you can use \array_values() after unset(), which will convert all keys to numerically enumerated keys starting from 0.Ĭode: $array = Note that when you use unset() the array keys won’t change. This only works if the element does not occur more than once, since \array_search returns the first hit only.
If you know the value and don’t know the key to delete the element you can use \array_search() to get the key. If you want to delete just one array element you can use unset() or alternatively \array_splice(). There are different ways to delete an array element, where some are more useful for some specific tasks than others.
