(PHP 5 >= 5.3.0, PHP 7, PECL phar >= 1.0.0)
PharFileInfo::__construct — Construct a Phar entry object
$entry
   )This should not be called directly. Instead, a PharFileInfo object is initialized by calling Phar::offsetGet() through array access.
entryThe 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.
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.
Example #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;
}
?>
以上例程会输出:
line number 1: hi line number 2: there line number 3: dude line number 1: hi line number 2: there line number 3: dude
