# Phar::offsetSet

(no version information, might be only in CVS)

Phar::offsetSet -- set the contents of an internal file to those of an external file

## Descrição

void Phar::offsetSet ( string offset, string value )

This is an implementation of the ArrayAccess interface allowing direct manipulation of the contents of a Phar archive using array access brackets. offsetSet is used for modifying an existing file, or adding a new file to a Phar archive.

## Parâmetros

`offset`

  The filename (relative path) to modify in a Phar.

`value`

  Content of the file.

## Valores de retornado

No return values.

## Erros/Excessões

if phar.readonly is `1`, BadMethodCallException is thrown, as modifying a Phar is only allowed when phar.readonly is set to `0`. Throws PharException if there are any problems flushing changes made to the Phar archive to disk.

## Exemplos

Exemplo 1. A Phar::offsetSet() example offsetSet should not be accessed directly, but instead used via array access with the [] operator.
`<?php $p = new Phar('/path/to/my.phar', 0, 'my.phar'); try { // calls offsetSet $p['file.txt'] = 'Hi there'; } catch (Exception $e) { echo 'Could not modify file.txt:', $e; } ?>`
