In laravel, dd () belongs to the laravel helper function; the dd function is used to output a given value and end the script, printing all variables in laravel with the syntax "dd ($value1,$value2...)".

This article operating environment: Windows10 system, Laravel6 version, Dell G3 computer.

Is dd a function in laravel?

The dd function outputs the given value and ends the script running:

Dd ($value); dd ($value1, $value2, $value3,...)

The example PHP globally uses the Laravel helper function dd:

Global composer.json

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

Configure PHP.ini

Auto_prepend_file = "C:UsersMSAppDataRoamingComposervendorautoload.php"

Update Composer

Composer global update

Restart apache after updating and you can use the function dump () globally.

Dd () method

Global composer.json

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

Create a new 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 {/ * * Big column PHP globally uses the Laravel helper function 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 ZMuiindexconst' 100000000, '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?
