调用aritsan命令Artisan：：call (‘cache:clear’)时，Laravel出现错误‘尝试访问int类型的值上的数组偏移量’；

Question

我正在尝试使用代码清除缓存。它抛出了一个错误Trying to access array offset on value of type int

Route::get('/clear-cache', function() {
    Artisan::call('cache:clear');
    return "Cache is cleared";
});

行elseif ('-' === $key[0])中有错误

protected function parse()
{
    foreach ($this->parameters as $key => $value) {
        if ('--' === $key) {
            return;
        }
        if (0 === strpos($key, '--')) {
            $this->addLongOption(substr($key, 2), $value);
        } elseif ('-' === $key[0]) {
            $this->addShortOption(substr($key, 1), $value);
        } else {
            $this->addArgument($key, $value);
        }
    }
}

键变量现在可能不是数组。您可以显式地将此类型转换为数组

protected function parse()
{
    foreach ($this->parameters as $key => $value) {
        $key = (array)$key;
        if ('--' === $key) {
            return;
        }
        if (0 === strpos($key, '--')) {
            $this->addLongOption(substr($key, 2), $value);
        } elseif ('-' === $key[0]) {
            $this->addShortOption(substr($key, 1), $value);
        } else {
            $this->addArgument($key, $value);
        }
    }
}
