How to Remove Specific Item from a Set in PHP

How to Remove Specific Item from a Set in PHP ?

To remove a specific item from a set in PHP, you can use the unset() function.

In this example,

First, we create a set of integers named $numberSet with values $numberSet = [1, 2, 3, 4, 5];.
Next, we use the unset() function to remove the item '2' from $numberSet.
The unset() function removes the specified item from the set.
We print the updated set to verify that '2' has been removed.

<?php 
$numberSet = [1, 2, 3, 4, 5];
unset($numberSet[array_search(2, $numberSet)]);
print_r($numberSet);
?>

Array
(
    [0] => 1
    [1] => 3
    [2] => 4
    [3] => 5
)

In this example,

First, we create a set of strings named $stringSet with values $stringSet = ['apple', 'banana', 'orange'];.
Next, we use the unset() function to remove the string 'banana' from $stringSet.
The unset() function removes the specified item from the set.
We print the updated set to verify that 'banana' has been removed.

<?php 
$stringSet = ['apple', 'banana', 'orange'];
unset($stringSet[array_search('banana', $stringSet)]);
print_r($stringSet);
?>

Array
(
    [0] => apple
    [1] => orange
)
