dump() 方法

全局 composer.json

"require": { "squizlabs/php_codesniffer": "*", "fxp/composer-asset-plugin": "^1.4", "symfony/var-dumper": "3.3.16"}

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

# 新增 autoload"autoload": { "files": [ "D:/web/php/debugHelper.php" ]}

新建 debugHelper.php

# install symfony/var-dump to your project# composer require symfony/var-dumper// use namespaceuse ComponentVarDumperClonerVarCloner;use ComponentVarDumperDumperCliDumper;use ComponentVarDumperDumperHtmlDumper as SymfonyHtmlDumper;/** * Class HtmlDumper */class HtmlDumper extends SymfonyHtmlDumper{ /**大专栏 PHP 全局使用 Laravel 辅助函数 ddnt"> * Colour definitions for output. * * @var array */ protected $styles = [ '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', 'num' => 'color:#a71d5d', 'const' => 'color:#795da3', 'str' => 'color:#df5000', 'cchr' => 'color:#222', 'note' => 'color:#a71d5d', 'ref' => 'color:#a0a0a0', 'public' => 'color:#795da3', 'protected' => 'color:#795da3', 'private' => 'color:#795da3', 'meta' => 'color:#b729d9', 'key' => 'color:#df5000', 'index' => 'color:#a71d5d', ];}/** * Class Dumper */class Dumper{ /** * Dump a value with elegance. * * @param mixed $value * @return void */ public function dump($value) { if (class_exists(CliDumper::class)) { $dumper = 'cli' === PHP_SAPI ? new CliDumper : new HtmlDumper; $dumper->dump((new VarCloner)->cloneVar($value)); } else { var_dump($value); } }}if (! function_exists('dd')) { /** * Dump the passed variables and end the script. * * @param mixed * @return void */ function dd(...$args) { foreach ($args as $x) { (new Dumper)->dump($x); } die(1); }}if (! function_exists('dda')) { /** * Dump the passed array variables and end the script. * * @param mixed * @return void */ function dda(...$args) { foreach ($args as $x) { (new Dumper)->dump($x->toArray()); } die(1); }}
