Phar::offsetGet — Gets a PharFileInfo object for a specific file

### 설명

int Phar::offsetGet ( string `$offset` )

This is an implementation of the ArrayAccess interface allowing direct manipulation of the contents of a Phar archive using array access brackets. Phar::offsetGet is used for retrieving files from a Phar archive.

### 인수

`offset`

  The filename (relative path) to look for in a Phar.

### 반환값

A PharFileInfo object is returned that can be used to iterate over a file's contents or to retrieve information about the current file.

### 오류/예외

This method throws BadMethodCallException if the file does not exist in the Phar archive.

### 예제

Example #1 Phar::offsetGet() example

As with all classes that implement the ArrayAccess interface, Phar::offsetGet is automatically called when using the [] angle bracket operator.

`<?php
$p = new Phar(dirname(__FILE__) . '/myphar.phar', 0, 'myphar.phar');
$p['exists.txt'] = "file exists\n";
try {
// automatically calls offsetGet()
echo $p['exists.txt'];
echo $p['doesnotexist.txt'];
} catch (BadMethodCallException $e) {
echo $e;
}
?>`

위 예제의 출력:

    file exists
    Entry doesnotexist.txt does not exist
