7. Insert New Array Item by Position

Write a PHP script that inserts a new item in an array in any position.

Sample Solution:

PHP Code:

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

// Output a message indicating the original array
echo 'Original array : ' . "\n";

// Iterate through the elements of the original array and echo them
foreach ($original as $x) {
    echo "$x ";
}

// Define a string '$' to be inserted into the array
$inserted = '$';

// Use array_splice() to insert the value '$' at index 3 in the original array
array_splice($original, 3, 0, $inserted);

// Output a message indicating the array after the insertion
echo " \n After inserting '$' the array is : " . "\n";

// Iterate through the modified array and echo its elements
foreach ($original as $x) {
    echo "$x ";
}

// Output a newline character for better formatting
echo "\n";
?>

Output:

Original array :                                            
1 2 3 4 5                                                   
 After inserting '$' the array is :                         
1 2 3 $ 4 5
