在本篇文章里小编给大家整理了关于PHP全局使用Laravel辅助函数dd的相关知识点，需要的朋友们学习下。

dump() 方法

全局 composer.json

1. "require": {
2. "squizlabs/php_codesniffer": "*",
3. "fxp/composer-asset-plugin": "^1.4",
4. "symfony/var-dumper": "3.3.16"
5. }

配置PHP.ini

auto_prepend_file = "C:UsersMSAppDataRoamingComposervendorautoload.php"

更新Composer

composer global update

更新后重启apache就可以全局使用函数 dump()

dd() 方法

全局 composer.json

1. # 新增 autoload
2. "autoload": {
3. "files": [
4. "D:/web/php/debugHelper.php"
5. ]
6. }

新建 debugHelper.php

1. # install symfony/var-dump to your project
2. # composer require symfony/var-dumper
3. // use namespace
4. use ComponentVarDumperClonerVarCloner;
5. use ComponentVarDumperDumperCliDumper;
6. use ComponentVarDumperDumperHtmlDumper as SymfonyHtmlDumper;
7. /**
8. * Class HtmlDumper
9. */
10. class HtmlDumper extends SymfonyHtmlDumper
11. {
12. /**
13. 大专栏 PHP 全局使用 Laravel 辅助函数 ddnt"> * Colour definitions for output.
14. *
15. * @var array
16. */
17. protected $styles = [
18. 'default' => 'background-color:#fff; color:#222; line-height:1.2em; font-weight:normal; font:12px Monaco, Consolas, monospace; word-wrap: break-word; white-space: pre-wrap; position:relative; z-index:100000',
19. 'num' => 'color:#a71d5d',
20. 'const' => 'color:#795da3',
21. 'str' => 'color:#df5000',
22. 'cchr' => 'color:#222',
23. 'note' => 'color:#a71d5d',
24. 'ref' => 'color:#a0a0a0',
25. 'public' => 'color:#795da3',
26. 'protected' => 'color:#795da3',
27. 'private' => 'color:#795da3',
28. 'meta' => 'color:#b729d9',
29. 'key' => 'color:#df5000',
30. 'index' => 'color:#a71d5d',
31. ];
32. }
33. /**
34. * Class Dumper
35. */
36. class Dumper
37. {
38. /**
39. * Dump a value with elegance.
40. *
41. * @param mixed $value
42. * @return void
43. */
44. public function dump($value)
45. {
46. if (class_exists(CliDumper::class)) {
47. $dumper = 'cli' === PHP_SAPI ? new CliDumper : new HtmlDumper;
48. $dumper->dump((new VarCloner)->cloneVar($value));
49. } else {
50. var_dump($value);
51. }
52. }
53. }
54. if (! function_exists('dd')) {
55. /**
56. * Dump the passed variables and end the script.
57. *
58. * @param mixed
59. * @return void
60. */
61. function dd(...$args)
62. {
63. foreach ($args as $x) {
64. (new Dumper)->dump($x);
65. }
66. die(1);
67. }
68. }
69. if (! function_exists('dda')) {
70. /**
71. * Dump the passed array variables and end the script.
72. *
73. * @param mixed
74. * @return void
75. */
76. function dda(...$args)
77. {
78. foreach ($args as $x) {
79. (new Dumper)->dump($x->toArray());
80. }
81. die(1);
82. }
83. }

更新composer自动加载

composer global dump-autoload

更新后就可以全局使用函数 dd()
