`vsprintf()` is a PHP function that formats a string using an array of arguments, similar to `sprintf()` but accepting an array instead of variable arguments.PHP 8.PHP 8.1,PHP 8.2,PHP 8.3,and PHP 8.4.

Syntax<?phpvsprintf(string $format, array $values): string|false?>Example 1: Basic usage$format = "There are %d monkeys in the %s";$args = [5, "tree"];$result = vsprintf($format, $args);echo $result; // Output: There are 5 monkeys in the tree

Key Points1. `vsprintf()` works exactly like `sprintf()` but takes an array of arguments2. In PHP 8.2, argument mismatches throw a `ValueError` (previously a warning)3. Useful when you have arguments in an array or need to pass them dynamically4. Supports all the same format specifiers as `sprintf()`The function returns the formatted string or `false` on failure (though in PHP 8.2, most failures throw exceptions instead).
