PHP5中文手册·get a PharFileInfo object for a specific file -- 追寻梦想＞编程乐园＞PHP 编程

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

Example#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;
}
?>

上例将输出：

file exists
Entry doesnotexist.txt does not exist
