(no version information, might be only in CVS)
Phar::offsetGet -- get a PharFileInfo object for a specific file
说明
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. 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.
错误/异常
This method throws BadMethodCallException if the file
does not exist in the Phar archive.
范例
例 1. A Phar::offsetGet() example
As with all classes that implement the ArrayAccess
interface, 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; } ?>
