PHP编译错误:"不能在数组中使用空数组元素"

Question

我有一个Laravel 5项目使用bepsvpt/secure-headers包和以下配置文件:

config/secure-headers.php

<?php

return [
    'x-content-type-options' => 'nosniff',
    'x-download-options' => 'noopen',
    'x-frame-options' => 'sameorigin',
    'x-permitted-cross-domain-policies' => 'none',
    'x-xss-protection' => '1; mode=block',

    /*

     *                  'same-origin', 'strict-origin', 'strict-origin-when-cross-origin', 'unsafe-url'
     */

    'referrer-policy' => 'strict-origin-when-cross-origin',

    'hsts' => [
        'enable' => env('SECURITY_HEADER_HSTS_ENABLE', false),
        'max-age' => 15552000,
        'include-sub-domains' => false,
    ],

    /*

     */

    'custom-csp' => env('SECURITY_HEADER_CUSTOM_CSP', null),

    'csp' => [
        'report-only' => false,

        'report-uri' => env('CONTENT_SECURITY_POLICY_REPORT_URI', false),,

        'upgrade-insecure-requests' => false,

        'base-uri' => [
            //
        ],

        'default-src' => [
            //
        ],

        'child-src' => [
            //

        'script-src' => [
            'allow' => [
                //

            'hashes' => [
                // ['sha256' => 'hash-value'],
            ],

            'nonces' => [
                //
            ],

            'self' => false,

            'unsafe-inline' => false,

            'unsafe-eval' => false,
        ],

        'style-src' => [
            'allow' => [
                //
            ],

            'self' => false,

            'unsafe-inline' => false,
        ],

        'img-src' => [
            'allow' => [
                //
            ],

            'types' => [
                //
            ],

            'self' => false,

            'data' => false,
        ],

        /*
         * The following directives are all use 'allow' and 'self' flag.
         *
         * Note: default value of 'self' flag is false.
         */

        'font-src' => [
            //
        ],

        'connect-src' => [
            //
        ],

        'form-action' => [
            //
        ],

        'frame-ancestors' => [
            //
        ],

        'media-src' => [
            //
        ],

        'object-src' => [
            //
        ],

        /*
         * plugin-types only support 'allow'.
         */

        'plugin-types' => [
            //
        ],
    ],
];

当我尝试运行应用程序(Web请求或php artisan)时,我收到以下错误:

PHP Fatal error:  Cannot use empty array elements in arrays in C:\Web\myapp\config\secure-headers.php on line 4

当然,该文件的第4行看起来完全没问题!

这是什么问题？

Answer 1

这个错误在我可以在网上找到的任何地方都没有记录,来自连续两个逗号,它们在数组中没有任何内容.

在我的情况下,这实际上出现在文件的第42行,而不是第4行,如错误消息所示,这听起来像编译器中的错误,它识别数组中的第一项而不是"空数组的实际位置"元件".

Answer 2

我得到了同样的错误,同时指向第2行,错误在第6行.

我花了几个小时无助地进行故障排除,因为它是一个熟悉的代码,我不知道什么时候额外,得到了'available' => $faker->boolean(85),

return [
  'id'          => $id,
  'user_id'     => $id,
  'slug'        => $slug,
  'speciality'  => $faker->randomElement(['Option A','Optoin B']),
  'available'   => $faker->boolean(85),,
  'subscription_ends_at' => $faker->dateTimeBetween('-5 day', '30 day'),
  'verified_at' => $faker->dateTimeBetween('-50 day', '-16 minute'),
];

只需,,, ,在@Moshe Katz指出的同一行中搜索代码或两个逗号之间的空格即可.
