How to remove elements from an array in PHP?

@orpha 

To remove elements from an array in PHP, you can use several built-in functions depending on your use case:

1. unset() function: You can use the unset() function to remove a specific element from an array. It takes the array and the index of the element you want to remove as arguments.

Here's an example:

1
2
3

$array = array('apple', 'banana', 'orange', 'grape');
unset($array[2]); // removes 'orange' from the array
print_r($array); // prints Array ( [0] => apple [1] => banana [3] => grape )

1. array_splice() function: The array_splice() function allows you to remove a range of elements from an array. It takes the array, the start index of the range, the length of the range, and an optional replacement array as arguments.

Here's an example:

1
2
3

$array = array('apple', 'banana', 'orange', 'grape');
array_splice($array, 1, 2); // removes 'banana' and 'orange' from the array
print_r($array); // prints Array ( [0] => apple [1] => grape )

1. array_filter() function: The array_filter() function allows you to remove elements from an array based on a condition. It takes the array and a callback function as arguments. The callback function should return true for the elements you want to keep and false for the elements you want to remove.

Here's an example:

1
2
3
4
5

$array = array('apple', 'banana', 'orange', 'grape');
$array = array_filter($array, function($value) {
    return $value != 'orange'; // removes 'orange' from the array
});
print_r($array); // prints Array ( [0] => apple [1] => banana [3] => grape )
