PharFileInfo::__construct()

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

Construct a Phar entry object

说明

publicPharFileInfo::__construct(string $entry)

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

参数

$entry

The full url to retrieve a file. If you wish to retrieve the information for the filemy/file.phpfrom the pharboo.phar, the entry should bephar://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.

范例

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
