I really love <code>var_export()</code>. If you like copy/paste-able code, try:

<pre><code>echo '&lt;pre&gt;' . var_export($data, true) . '&lt;/pre&gt;';
</code></pre>

Or even something like this for color syntax highlighting:

<pre><code>highlight_string("&lt;?php\n\$data =\n" . var_export($data, true) . ";\n?&gt;");
</code></pre>

You can do the same with <code>print_r()</code>. For <code>var_dump()</code> you would just need to add the <code>&lt;pre&gt;</code> tags:

<pre><code>echo '&lt;pre&gt;';
var_dump($data);
echo '&lt;/pre&gt;';
</code></pre>

I have make an addition to @AbraCadaver answers.
I have included a javascript script which will delete php starting and closing tag.
We will have clean more pretty dump.

May be somebody like this too.

<pre><code>function dd($data){
 highlight_string("&lt;?php\n " . var_export($data, true) . "?&gt;");
 echo '&lt;script&gt;document.getElementsByTagName("code")[0].getElementsByTagName("span")[1].remove() ;document.getElementsByTagName("code")[0].getElementsByTagName("span")[document.getElementsByTagName("code")[0].getElementsByTagName("span").length - 1].remove() ; &lt;/script&gt;';
 die();
}

Result before:

I had to add another answer here because I didn't really want to go through the steps in the other solutions. It is extremely simple and requires no extensions, includes etc and is what I prefer. It's very easy and very fast.

First just json_encode the variable in question:

<pre><code>echo json_encode($theResult);
</code></pre>

Copy the result you get into the JSON Editor at <a href="http://jsoneditoronline.org/" rel="nofollow noreferrer">http://jsoneditoronline.org/</a> just copy it into the left side pane, click Copy > and it pretty prints the JSON in a really nice tree format.

To each their own, but hopefully this helps some others have one more nice option! :)

If it's "all smushed together" you can often give the ol' "view source code" a try. Sometimes the dumps, messages and exceptions seem like they're just one long string when it turns out that the line breaks simply don't show. Especially XML trees.

Alternatively, I've once created a small little tool called <a href="https://github.com/woodrowshigeru/InteractiveVarDump" rel="nofollow noreferrer">InteractiveVarDump</a> for this very purpose. It certainly has its limits but it can also be very convenient sometimes. Even though it was designed with PHP 5 in mind.

The best what and easiest way to get nice var_dump is use xDebug (must have for any php dev)
Debian way install

In console: <code>apt-get install php-xdebug</code>
after that you should open php.ini (depends on which stack you use) for it's /etc/php/7.0/fpm/php.ini

Search for <code>display_errors</code>

set same -> <code>display_errors = On</code>

Check <code>html_errors</code> in same file a little bit below, it's also must be <code>On</code>

Save and exit

After open <code>/etc/php/7.0/fpm/conf.d/20-xdebug.ini</code>

And add to the end:
```
xdebug.cli_color=1

```
Save and exit.

A lot other available option and documentation for xdebug can be founded here.

<a href="https://github.com/kint-php/kint" rel="nofollow noreferrer">https://github.com/kint-php/kint</a>
It works with zero set up and has more features than Xdebug's var_dump.
Example which bypasses the dumped object size limit on the fly with Kint:
<pre class="lang-php prettyprint-override"><code> require 'kint.phar';
 +d( $variable ); // append `+` to the dump call
</code></pre>

Here is my function to have a pretty var_dump. Combined with <a href="https://xdebug.org/index.php" rel="nofollow noreferrer">Xdebug</a>, it helps a lot to have a better view of what we are dumping.

I improved a bit the display of Xdebug (give some space around, separator between values, wrap long variables, etc).

When you call the function, you can set a title, a background, a text color to distinguish all your var_dump in a page.

Or not ;)

Here is a function I made for showing arrays in a nice way:
<pre><code>function nicevar($var,$title=''){
 if(is_array($var)){
 $table = '&lt;table&gt;';
 if($title){
 $table .= '&lt;tr&gt;&lt;th colspan=&quot;20&quot;&gt;'.$title.'&lt;/th&gt;&lt;/tr&gt;';
 }
 foreach($var as $k =&gt; $v){
 $table .= '&lt;tr&gt;';
 $table .= '&lt;td&gt;&lt;b&gt;'.$k.'&lt;/b&gt;&lt;/td&gt;';
 $table .= '&lt;td&gt;';
 if(is_array($v)){
 $table .= nicevar($v);
 }else{
 $table .= $v;
 }
 $table .= '&lt;/td&gt;';
 $table .= '&lt;/tr&gt;';
 }
 $table .= '&lt;/table&gt;';
 }else{
 $table = $var;
 }
 return $table; 
}
</code></pre>
usage:
<pre><code>echo nicevar($_SESSION['debug'],'Structure of debug');
</code></pre>
use this styling to make it nice:
<pre class="lang-html prettyprint-override"><code>&lt;style&gt;
body {
 padding: 30px;

table {
 margin: 5px;
}
table, th, td {

 if(FALSE == empty($var) &amp;&amp; $var !== NULL &amp;&amp; $var != '0') {
 if(is_array($var)) {
 echo "Number of Indexes: " . count($var) . "\n";
 print_r($var);
 } elseif(is_object($var)) {
 print_r($var);
 } elseif(@is_file($var)){
 $stat = stat($var);
 $perm = substr(sprintf('%o',$stat['mode']), -4);
 $accesstime = gmdate('Y/m/d H:i:s', $stat['atime']);
 $modification = gmdate('Y/m/d H:i:s', $stat['mtime']);
 $change = gmdate('Y/m/d H:i:s', $stat['ctime']);

This should work ^^

I have a simple <code>$_GET[]</code> query var set for showing testing data when pulling down queries from the DB.

<pre><code>&lt;?php if($_GET['test']): ?&gt;
 &lt;div id="test" style="padding: 24px; background: #fff; text-align: center;"&gt; 
 &lt;table&gt;
 &lt;tr style="font-weight: bold;"&gt;&lt;td&gt;MLS&lt;/td&gt;&lt;/tr&gt;
 &lt;tr&gt;&lt;td&gt;&lt;?php echo KEY; ?&gt;&lt;/td&gt;&lt;/tr&gt;
 &lt;tr style="font-weight: bold;"&gt;&lt;td&gt;QUERY&lt;/td&gt;&lt;/tr&gt;
 &lt;tr&gt;&lt;td&gt;&lt;?php echo $data_q; ?&gt;&lt;/td&gt;&lt;/tr&gt;
 &lt;tr style="font-weight: bold;"&gt;&lt;td&gt;DATA&lt;/td&gt;&lt;/tr&gt;
 &lt;tr&gt;&lt;td&gt;&lt;?php var_dump($data); ?&gt;&lt;/td&gt;&lt;/tr&gt;
 &lt;/table&gt; 
&lt;/div&gt;
&lt;?php endif; ?&gt;
</code></pre>

When I do <code>var_dump</code>, as expected it's this big array string that is all smushed together. Is there a way to add in line breaks at least for this or display the <code>var_dump</code> in a way that's more readable? I'm open to jQuery suggestions on manipulating the string after it's posted.

Make var_dump look pretty

数据库

jQuery

Debian

JSON

我有一个简单的$_GET[]查询变量集，用于在从数据库下拉查询时显示测试数据。<?php if($_GET['test']): ?> <div id="test" style="padding: 24px; background: #fff; text-align: center;"> <table> <tr style="font-weight: bold;"><td>ML
