Remove a child from an array in PHP?

Question

Lets say I have this array:

$queue = array("orange", "banana", 'apple', 'watermelon');

If I want to remove any of them,for example I want to remove banana, how to do it?

Answer 1

You'll need to search for that element and remove it using the key:

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

If the array can contain the value more than once, you should use array_keys() instead:

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

Answer 2

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

Answer 3

with array_filter:

$array = array_filter($array, create_function('$v', 'return $v != \'value to remove\';'));
