  📌 PHP array_pad() Function Tutorial with Examples The array_pad() function in PHP is used to pad an array to a specified length with a specified value . If the array has fewer elements than the target size, it fills the rest with the value you provide. 📌 Syntax: array_pad ( array $array , int $size , mixed $value ): array Parameters: $array → The original array you want to pad. $size → The target size of the new array. Positive value: Pads to the end (right). Negative value: Pads to the beginning (left). $value → The value to use for padding. 📌 How it Works: If the array is already equal to or larger than the desired size, no padding is added. If it's smaller, the function adds the specified value until the array reaches the target size. It returns a new array — the original remains unchanged. 📌 Example 1: Pad Array to the Right <?php $fruits = array ( "Apple" , "Banana" ); $result = array_pad ( $fr...
