PHP: How to remove specific element from an array?

Question

Use array_search to get the key and remove it with unset if found:

if (($key = array_search('strawberry', $array)) !== false) {
    unset($array[$key]);
}

array_search returns false (null until PHP 4.2.0) if no item has been found.

And if there can be multiple items with the same value, you can use array_keys to get the keys to all items:

foreach (array_keys($array, 'strawberry') as $key) {
    unset($array[$key]);
}

Use array_diff() for 1 line solution:

$array = array('apple', 'orange', 'strawberry', 'blueberry', 'kiwi', 'strawberry'); //throw in another 'strawberry' to demonstrate that it removes multiple instances of the string
$array_without_strawberries = array_diff($array, array('strawberry'));
print_r($array_without_strawberries);

...No need for extra functions or foreach loop.

if (in_array('strawberry', $array)) 
{
    unset($array[array_search('strawberry',$array)]);
}

If you are using a plain array here (which seems like the case), you should be using this code instead:

if (($key = array_search('strawberry', $array)) !== false) {
    array_splice($array, $key, 1);
}

unset($array[$key]) only removes the element but does not reorder the plain array.

Supposingly we have an array and use array_splice:

$array = array('apple', 'orange', 'strawberry', 'blueberry', 'kiwi');
array_splice($array, 2, 1);
json_encode($array); 
// yields the array ['apple', 'orange', 'blueberry', 'kiwi']

Compared to unset:

$array = array('apple', 'orange', 'strawberry', 'blueberry', 'kiwi');
unset($array[2]);
json_encode($array);
// yields an object {"0": "apple", "1": "orange", "3": "blueberry", "4": "kiwi"}

Notice how unset($array[$key]) does not reorder the array.

You can use array filter to remove the items by a specific condition on $v:

$arr = array_filter($arr, function($v){
    return $v != 'some_value';
});

Just u can do single line .it will be remove element from array

$array=array_diff($array,['strawberry']);
