Phar::offsetGet

(PHP 5 >= 5.3.0, PHP 7, PHP 8, PECL phar >= 1.0.0)

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

说明

public Phar::offsetGet(string $localName): SplFileInfo

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

localName: 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

示例 #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
