# vfprintf

(PHP 5)

vfprintf -- Write a formatted string to a stream

## Description

int vfprintf ( resource handle, string format, array args )

Write a string produced according to `format` to the stream resource specified by `handle`. `format` is described in the documentation for sprintf().

Operates as fprintf() but accepts an array of arguments, rather than a variable number of arguments.

Returns the length of the outputted string.

See also: printf(), sprintf(), sscanf(), fscanf(), vsprintf(), and number_format().

## Examples

Exemplo 1. vfprintf(): zero-padded integers
`<?php if (!($fp = fopen('date.txt', 'w'))) return; vfprintf($fp, "%04d-%02d-%02d", array($year, $month, $day)); // will write the formatted ISO date to date.txt ?>`
