php - 在 PHP 中包含名称空间的文件意外终止脚本，即使它是 include_once
问题描述
我首先尝试将每个文件包含在 GitHub 项目中。我的目的是在那之后调用 get_declared_classes() 作为一种反射形式，这样我就可以了解项目中声明了哪些类。我从没想过会遇到这个问题，经过大量研究和测试后我没有解决方案。请帮忙。
我正在使用的项目：https ://github.com/farafiri/PHP-parsing-tool
我把它下载到一个文件夹中。写了这段代码：
$toparse = shell_exec("find '/Users/user/Documents/PHP-parsing-tool-master/src' -iname '*.php' 2> /dev/null");
$filenames = explode("\n", $toparse);
//d() is a custom function that acts like var_dump.
d($filenames);
$filenames 转储（请原谅 d() 附带的自定义格式。基本上 $filenames 是一个由 77 个元素组成的数组，每个元素是一个字符串，表示 Github 项目中每个文件的路径）：

]
然后：
foreach ($filenames as $n=>$f) {
d($f);
include_once $f;
d($f);
}
直到索引为 15 的元素之前，foreach 循环都没有问题。脚本在包含该文件时终止。我知道这一点是因为执行包含之前的 d() 函数，而不是包含之后的 d() 函数。我在命令行上运行了脚本，并在 macOS 10.13.6 上使用了来自 MAMP 4 的 PHP7.2.10。
这是该文件的完整内容：
<?php
namespace ParserGenerator\Extension;
echo "hello in interface";
interface ExtensionInterface
{
function extendGrammar($grammarGrammar);
function modifyBranches($grammar, $parsedGrammar, $grammarParser, $options);
function createGrammarBranch($grammar, $grammarBranch, $grammarParser, $options);
function fillGrammarBranch($grammar, $grammarBranch, $grammarParser, $options);
function buildSequenceItem(&$grammar, $sequenceItem, $grammarParser, $options);
function buildSequence($grammar, $rule, $grammarParser, $options);
}
echo "hello in interface 2";
回显“界面中的你好”后脚本终止。“接口 2 中的你好”从未得到回应。
奇怪的是，即使我的 php.ini 文件已经设置为 error_reporting=E_ALL 和 display_errors=On，也没有任何关于脚本终止的信息被转储到我的终端。没有解析错误，致命错误等。
有什么问题，如何让脚本一直执行到最后？抱歉，但我在命名空间和接口上遗漏了什么吗？
