### Parameters

`offset`

  The filename (relative path) to modify in a tar or zip archive.

`value`

### Return Values

### Errors/Exceptions

### Examples

Example #1 A PharData::offsetSet example

offsetSet should not be accessed directly, but instead used via array access with the [] operator.

`<?php
$p = new PharData('/path/to/my.tar');
try {
// calls offsetSet
$p['file.txt'] = 'Hi there';
} catch (Exception $e) {
echo 'Could not modify file.txt:', $e;
}
?>`
