PHP Array Exercises : Delete an element from an array

PHP Array: Exercise-4 with Solution

$x = array(1, 2, 3, 4, 5);
Delete an element from the above array. After deleting the element, integer keys must be normalized.

Sample Solution:

PHP Code:

<?php
// Create an indexed array $x with elements 1, 2, 3, 4, 5
$x = array(1, 2, 3, 4, 5);

// Dump the variable $x to display its structure and values
var_dump($x);

// Unset the element with index 3 in the array $x
unset($x[3]);

// Reset the array indices after unset using array_values()
$x = array_values($x);

// Echo a newline character for better formatting
echo '';

// Dump the variable $x again after unset and array_values
var_dump($x);
?>

Output:

array(5) {                                                  
  [0]=>                                                     
  int(1)                                                    
  [1]=>                                                     
  int(2)                                                    
  [2]=>                                                     
  int(3)                                                    
  [3]=>                                                     
  int(4)                                                    
  [4]=>                                                     
  int(5)                                                    
}                                                           
array(4) {                                                  
  [0]=>                                                     
  int(1)                                                    
  [1]=>                                                     
  int(2)                                                    
  [2]=> 
  int(3)                                                    
  [3]=>                                                     
  int(5)
