# PharFileInfo::__construct

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

PharFileInfo::__construct — Construct a Phar entry object

### 说明

public PharFileInfo::__construct(string `$filename`)

This should not be called directly. Instead, a PharFileInfo object is initialized by calling Phar::offsetGet() through array access.

### 参数

`filename`

  The full url to retrieve a file. If you wish to retrieve the information for the file `my/file.php` from the phar `boo.phar`, the entry should be `phar://boo.phar/my/file.php`.

### 错误／异常

Throws BadMethodCallException if __construct() is called twice. Throws UnexpectedValueException if the phar URL requested is malformed, the requested phar cannot be opened, or the file can't be found within the phar.

### 示例

示例 #1 A PharFileInfo::__construct() example

`<?php
try {
$p = new Phar('/path/to/my.phar', 0, 'my.phar');
$p['testfile.txt'] = "hi\nthere\ndude";
$file = $p['testfile.txt'];
foreach ($file as $line => $text) {
echo "line number $line: $text";
}
// this also works
$file = new PharFileInfo('phar:///path/to/my.phar/testfile.txt');
foreach ($file as $line => $text) {
echo "line number $line: $text";
}
} catch (Exception $e) {
echo 'Phar operations failed: ', $e;
}
?>`

以上示例会输出：

    line number 1: hi
    line number 2: there
    line number 3: dude
    line number 1: hi
    line number 2: there
    line number 3: dude
