A more pretty/informative Var_dump alternative in PHP?
提问by raveren
Every decent PHP programmer has a print_ror var_dumpwrapper they use, love and assign shortcut keys to, why don't we share our favourite ones.
每个体面的 PHP 程序员都有一个print_r或var_dump他们使用的包装器，喜欢并为其分配快捷键，我们为什么不分享我们最喜欢的。

A full year of time and labor after asking this, I've finally open sourced my version of var_dump, Kint. Read about it in the project page, or directly in github.
问这个问题后，我花了整整一年的时间和精力，终于开源了我的 var_dump 版本，Kint。在项目页面或直接在 github 中阅读它。

My prefered on is the var_dumpfunction, as provided by the Xdebug extension: just install the extension (easy, both on windows and Linux), and var_dumpgets a better output :
我上者优先的是var_dump功能，如Xdebug扩展提供：刚安装扩展（容易，无论是在Windows和Linux） ，并var_dump得到一个更好的输出：
- better formating
- HTML
- colors
- and you have options to tune how much informations should be displayed
- 更好的成型
- HTML
- 颜色
- 并且您可以选择调整应该显示多少信息
And a quick screenshot :

Here's mine, which I use inline, very useful:
这是我的，我使用内联，非常有用：
$pretty = function($v='',$c=" ",$in=-1,$k=null)use(&$pretty){$r='';if(in_array(gettype($v),array('object','array'))){$r.=($in!=-1?str_repeat($c,$in):'').(is_null($k)?'':"$k: ").'<br>';foreach($v as $sk=>$vl){$r.=$pretty($vl,$c,$in+1,$sk).'<br>';}}else{$r.=($in!=-1?str_repeat($c,$in):'').(is_null($k)?'':"$k: ").(is_null($v)?'<NULL>':"<strong>$v</strong>");}return$r;};
echo $pretty($some_variable);

You are looking for Krumo(Warning, Chrome alerts for Malware).
您正在寻找Krumo（警告，Chrome 恶意软件警报）。
To put it simply, Krumo is a replacement for print_r() and var_dump(). By definition Krumo is a debugging tool (initially for PHP4/PHP5, now for PHP5 only), which displays structured information about any PHP variable.
简单地说，Krumo 是 print_r() 和 var_dump() 的替代品。根据定义，Krumo 是一个调试工具（最初用于 PHP4/PHP5，现在仅用于 PHP5），它显示有关任何 PHP 变量的结构化信息。

- It writes the logging information out using headers, so it doesn't break AJAX.
- Gives you a very nice graphical representation of the variables/objects you log
- Can display file name and line number where each log statement occurs
- Easy to use in your project, either with a procedural or object-oriented API
- 它使用标头写出日志信息，因此它不会破坏 AJAX。
- 为您记录的变量/对象提供非常漂亮的图形表示
- 可以显示每个日志语句出现的文件名和行号
- 易于在您的项目中使用，无论是程序化的还是面向对象的 API

My (partial) solution for this is the simply add a function like this (using Google Chrome):
我的（部分）解决方案是简单地添加一个这样的功能（使用谷歌浏览器）：
<?
function console_dump($value)
{
?>
<script>
console.log(<? echo json_encode($value); ?>);
</script>
<?
}
?>
Press Ctrl + Shift + J (opens up the console), and you can find there the JSON structure. Even more useful for a pretty print of JSON responses ofcourse.
按 Ctrl + Shift + J（打开控制台），您可以在那里找到 JSON 结构。对于 JSON 响应的漂亮打印当然更有用。
