What potential issues can arise when using array_pad to resize an array in PHP?

One potential issue that can arise when using array_pad to resize an array in PHP is that if the original array is larger than the specified size, the function will not truncate the array but simply return the original array. To solve this issue, you can use array_slice after using array_pad to resize the array to ensure that it is exactly the desired size.

// Original array
$originalArray = [1, 2, 3, 4, 5];

// Resize the array using array_pad
$resizedArray = array_pad($originalArray, 7, 0);

// Ensure the array is exactly the desired size
$resizedArray = array_slice($resizedArray, 0, 7);

// Output the resized array
print_r($resizedArray);
