realpath() and SplFileInfo::getRealPath inside Phar

Description

I'm trying to include packages in my phar but many of them use realpath to files inside the Phar which spits out false instead of a path; breaking things. If the behavior was to return the same path when the path starts with phar:// it would just work.

The following code:

make_phar.php

<?php
$phar = new Phar('test.phar');
$phar->addFile('test.php');
$phar->setDefaultStub('test.php');
$phar->stopBuffering();

test.php

<?php
var_dump(
    __FILE__,
    realpath(__FILE__), 
    (new SplFileInfo(__FILE__))->getRealPath(),
);

php test.php && php make_phar.php && php test.phar

Resulted in this output:

string(45) "/home/murrant/projects/realpath_test/test.php"
string(45) "/home/murrant/projects/realpath_test/test.php"
string(45) "/home/murrant/projects/realpath_test/test.php"
string(62) "phar:///home/murrant/projects/realpath_test/test.phar/test.php"
bool(false)
bool(false)

But I expected this output instead:

string(45) "/home/murrant/projects/realpath_test/test.php"
string(45) "/home/murrant/projects/realpath_test/test.php"
string(45) "/home/murrant/projects/realpath_test/test.php"
string(62) "phar:///home/murrant/projects/realpath_test/test.phar/test.php"
string(62) "phar:///home/murrant/projects/realpath_test/test.phar/test.php"
string(62) "phar:///home/murrant/projects/realpath_test/test.phar/test.php"

PHP Version

PHP 8.3.7

No response

首先运行 make_phar.php、test.php 和提供的 php test.phar 命令，以复现 realpath() 和 SplFileInfo::getRealPath() 的错误结果。跟踪这些调用所涉及的 PHP 和 Phar 文件系统处理。完成标准是两个函数都返回预期输出中显示的 phar:// 路径，同时保持现有的非 Phar 结果不变。
