Phar::offsetGet
(PHP 5 >= 5.3.0, PHP 7, PECL phar >= 1.0.0)
Phar::offsetGet — Gets a PharFileInfo object for a specific file
说明
public Phar::offsetGet
( string $offset
) : PharFileInfo
This is an implementation of the ArrayAccess interface allowing direct manipulation of the contents of a Phar archive using array access brackets. Phar::offsetGet() is used for retrieving files from a Phar archive.
参数
offset- The filename (relative path) to look for in a Phar.
返回值
A PharFileInfo object is returned that can be used to iterate over a file's contents or to retrieve information about the current file.
范例
Example #1 Phar::offsetGet() example
As with all classes that implement the ArrayAccess
interface, Phar::offsetGet() is automatically
called when using the [] angle bracket operator.
<?php$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;}?>
以上例程会输出：
file exists Entry doesnotexist.txt does not exist
