It is dealing with recursive references, may highlight syntax and export closures. Requirements ------------ [](#requirements) - PHP 8.0 - 8.5. Installation ------------ [](#installation) The package could be installed with [Composer](https://getcomposer.org): ``` composer require yiisoft/var-dumper ``` General usage ------------- [](#general-usage) ### Quick debugging [](#quick-debugging) In case you want to echo a string representing variable contents use the following code: ``` \Yiisoft\VarDumper\VarDumper::dump($variable); ``` That is useful for quick debugging. By default, it goes deep `10` levels into variable and highlights syntax. You may adjust these settings via second and third argument of the method respectively. For convenience, you can use the functions: ``` // Prints variables: d($variable, /* Further variables to dump. */); // The same as above dump($variable, /* Further variables to dump. */); // Prints variables and terminate the current script: dd($variable, /* Further variables to dump. */); ``` ### Formatting debug string [](#formatting-debug-string) To get a string representing variable contents, same as above but without `echo`: ``` $string = \Yiisoft\VarDumper\VarDumper::create($variable)->asString(10, true); ``` `10` is maximum recursion depth and `true` is telling dumper to highlight syntax. ### Exporting as PHP code [](#exporting-as-php-code) In order to get a valid PHP expression string that can be evaluated by PHP parser, and the evaluation result will give back the variable value, use the following code: ``` $string = \Yiisoft\VarDumper\VarDumper::create($variable)->export(); ``` It is similar to `var_export()` but uses short array syntax, handles closures, and serializes objects. In the above `export()` will give you nicely formatted code. You can remove formatting by passing `false` as the first `$format` argument. `$useVariables` argument allows specifying array of variables that will be in `use` statement for closures. That is especially useful if an object contains callbacks that should get info from upper scope. `$serializeObjects` argument when given `false` allows to force turn off using of serialization for objects so instead closures and reflection API are used the same was as for exporting closures. De-serialization performance is better. Closures are way more readable. ### Exporting as JSON string [](#exporting-as-json-string) ``` $string = \Yiisoft\VarDumper\VarDumper::create($variable)->asJson(); ``` It is similar to `json_encode()` but uses short array syntax, handles closures, and serializes objects. In the above `asJson()` will give you nicely formatted code. You can remove formatting by passing `false` as the first `$format` argument. `$depth` argument allows you to set maximum recursion depth. Output destination ------------------ [](#output-destination) Choose one of existing classes or create a new one to control the destination where "dumps" will be sent to: - [EchoHandler](./src/Handler/EchoHandler.php) - Uses `echo` to write to stdout stream. - Used by default. - [StreamHandler](./src/Handler/StreamHandler.php) - Uses `ext-sockets` to sent dumps encoded with `json_encode` to a UDP socket. - [CompositeHandler](./src/Handler/CompositeHandler.php) - Helpful class to sent dumps to multiple handlers in a row, for example `EchoHandler` and `StreamHandler`. Output handlers are set via `VarDumper::setDefaultHandler()` method. Limitations ----------- [](#limitations) Current limitations are: - Variables or properties that are anonymous classes or contain anonymous classes are not supported. Documentation ------------- [](#documentation) - [Internals](docs/internals.md) If you need help or have a question, the [Yii Forum](https://forum.yiiframework.com/c/yii-3-0/63) is a good place for that.
