blocks|key|2028084|text|我一直在使用dBug，它模仿Coldfusion令人惊叹的cfdump标签：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2028085|http://dbug.ospinto.com/examples.php|2028086|entityMap|0|LINK|mutability|MUTABLE|url^0|T|6|0|0|10|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@$9|P|A|Q|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|R|8|@]|D|@$9|S|A|T|1|U]]|E|$]]|$1|H|3|-4|5|6|7|V|8|@]|D|@]|E|$]]]|I|$J|$5|K|L|M|E|$N|G]]]]

blocks|key|1814936|text|我的(部分)解决方案是简单地添加如下函数(使用Google+Chrome)：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1814937|<?
function+console_dump($value)
{+
?>
<script>
++++console.log(<?+echo+json_encode($value);+?>);
</script>
<?
}
?>|code-block|syntax|javascript|1814938|按Ctrl+%2B+Shift+%2BJ(打开控制台)，您可以在那里找到JSON结构。当然，对于漂亮的JSON响应打印更有用。|1814939|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

My (partial) solution for this is the simply add a function like this (using Google Chrome):

<pre><code>&lt;?
function console_dump($value)
{ 
?&gt;
&lt;script&gt;
 console.log(&lt;? echo json_encode($value); ?&gt;);
&lt;/script&gt;
&lt;?
}
?&gt;
</code></pre>

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.

Those fancy libraries are great ... except the overhead. If you want a simple, pretty var_dump that takes infinite parameters, try my function. It adds some simple HTML. Data attributes are added too, if you use HTML5, lower versions will just ignore them, but makes it easy to open element in browser console and get a little more info if what you see on screen is not enough.

The layout is very simple, no overhead. Provides a ton of info for each parameter including things like <code>gettype</code> and even <code>class</code> name for Object dumps (including XML). It's tried and true, I've been using it for years.

<pre><code>function preDump() { // use string "noEcho" to just get a string return only
 $args = func_get_args();
 $doEcho = TRUE; $sb;
 if ($args) {

And If you use Codeigniter, add it too your CI EXTREMELY SIMPLY. First, go to <code>application/config/autoload.php</code> and make sure the <code>helper</code> <code>'string'</code> is on.

<pre><code>$autoload['helper'] = array( 'string' ); 
</code></pre>

Then simply go create a file named <code>MY_string_helper.php</code> in <code>application/helpers</code> and simple insert the function in a typical <code>if</code> statement for existence check.

<pre><code>&lt;?php if (!defined('BASEPATH')) exit('No direct script access allowed');
 if (!function_exists('preDump')) {
 function preDump() {
 ...
 }
 }
// DON'T CLOSE PHP
</code></pre>

|OR|, if you want to take it a different direction.

The following snippet is the same as above, except will show your variables in the browser console. This can sometimes make it easier to debug sql object calls and other array and object calls where you're missing the key name or whatever.

<pre><code>function consoleDump() { // use string "noEcho" to just get a string return only
 $args = func_get_args();
 $doEcho = TRUE; $sb;
 if ($args) {
 $sb = '&lt;script type="text/javascript"&gt;console.log("&lt;" + new Array('.(count($args) &lt; 10 ? '49': '48').').join("-") + "[consoleDump: '.count($args).' items]" + new Array(50).join("-") + "&gt;"); console.log([';

 foreach (func_get_args() as $i =&gt; $arg) {
 if (gettype($arg) == 'string') if ($arg == 'noEcho') { $doEcho = FALSE; $sb = preg_replace('/(consoleDump: )[0-9]+/', 'consoleDump: '.(count($args)-1), $sb); continue; }
 $sb .= '{ "type": "'.gettype($arg).'", ';
 switch (gettype($arg)) {
 case "boolean":
 case "integer":
 case "string":
 $sb .= '"value": '.json_encode($arg);
 break;
 default:
 $sb .= '"value": '.json_encode($arg);
 if (is_object($arg) || is_array($arg)) $sb .= ', "count": '.json_encode(count((array)$arg));
 if (is_object($arg)) $sb .= ', "objectClass": "'.get_class($arg).'"';
 }
 $sb .= '}';
 if ($i &lt; count($args)-1) $sb .= ', ';
 }
 $sb .= ']); console.log("&lt;" + new Array(120).join("-") + "&gt;"); &lt;/script&gt;';
 }
 else {
 $sb = '&lt;script type="text/javascript"&gt;console.log("&lt;" + new Array(120).join("-") + "&gt;");console.log("consoleDump: [ERROR] No Parameters Found");console.log("&lt;" + new Array(120).join("-") + "&gt;");&lt;/script&gt;';
 }
 if ($doEcho) echo($sb);
 return $sb;
}
</code></pre>

Works with everything!

<pre><code>consoleDump($simpXMLvar, $_SESSION, TRUE, NULL, array( 'one' =&gt; 'bob', 'two' =&gt; 'bill' ), (object)array( 'one' =&gt; 'bob', 'two' =&gt; 'bill' ));


&lt;------------------------------------------------[consoleDump: 6 items]-------------------------------------------------&gt;

If you're dealing with very big arrays in PHP, this function may help:

<pre><code>function recursive_print ($varname, $varval) {
 if (! is_array($varval)):
 print $varname . ' = ' . var_export($varval, true) . ";&lt;br&gt;\n";
 else:
 print $varname . " = array();&lt;br&gt;\n";
 foreach ($varval as $key =&gt; $val):
 recursive_print ($varname . "[" . var_export($key, true) . "]", $val);
 endforeach;
 endif;
}
</code></pre>

It basically dumps the whole array where each element is in separate line, which is beneficial to find the right full paths for certain elements.

Example output:

<pre><code>$a = array();
$a[0] = 1;
$a[1] = 2;
$a[2] = array();
$a[2][0] = 'a';
$a[2][1] = 'b';
$a[2][2] = 'c';
</code></pre>

I'm surprised nobody mentioned the easiest (albeit not very pretty) code. If you just want to get a readable output (no colors or indentation), a simple <code>&lt;pre&gt;</code> around a <code>var_dump</code> works, as in:

<pre><code>echo "&lt;pre&gt;";
var_dump($myvariable);
echo "&lt;/pre&gt;";

Can't get much lower overhead than this!

This is a great tool which is intended to replace the buggy PHP function <code>var_dump</code> and <code>print_r</code>, since it can correctly identify the recursively referenced objects in a complex object structure. It also has a recursive depth control to avoid indefinite recursive display of some peculiar variables.

And in other cases, well you don't need much for a simple WP website for example

So I use:

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

that really help me a lot.

but because I prefer the DevConsole Environment I use this awesome but simple function:

<a href="https://codeinphp.github.io/post/outputting-php-to-browser-console/" rel="nofollow noreferrer">https://codeinphp.github.io/post/outputting-php-to-browser-console/</a>

Little tweak: 

<pre><code>&lt;?php 

/**
 * Logs messages/variables/data to browser console from within php
 *
 * @param $name: message to be shown for optional data/vars
 * @param $data: variable (scalar/mixed) arrays/objects, etc to be logged
 * @param $jsEval: whether to apply JS eval() to arrays/objects
 *
 * @return none
 * @author Sarfraz
 */
function logConsole($name, $data = NULL, $jsEval = FALSE)
{
 if (! $name) return false;

 $isevaled = false;
 $type = ($data || gettype($data)) ? 'Type: ' . gettype($data) : '';

 if ($jsEval &amp;&amp; (is_array($data) || is_object($data)))
 {
 $data = 'eval(' . preg_replace('#[\s\r\n\t\0\x0B]+#', '', json_encode($data)) . ')';
 $isevaled = true;
 }
 else
 {
 $data = json_encode($data, JSON_PRETTY_PRINT | JSON_UNESCAPED_SLASHES);
 }

 # sanitalize
 $data = $data ? $data : '';
 $search_array = array("#'#", '#""#', "#''#", "#\n#", "#\r\n#");
 $replace_array = array('"', '', '', '\\n', '\\n');
 $data = preg_replace($search_array, $replace_array, $data);
 $data = ltrim(rtrim($data, '"'), '"');
 $data = $isevaled ? $data : ($data[0] === "'") ? $data : "'" . $data . "'";

$js = &lt;&lt;&lt;JSCODE
\n&lt;script&gt;
// fallback - to deal with IE (or browsers that don't have console)
if (! window.console) console = {};
console.log = console.log || function(name, data){};
// end of fallback

console.log('===== PHP Dump =====');
console.log('$name');
console.log('$type');
console.log($data);
console.log('===== / PHP Dump =====');
console.log('\\n');
&lt;/script&gt;
JSCODE;

 echo $js;
} # end logConsole
</code></pre>

Every decent PHP programmer has a <code>print_r</code> or <code>var_dump</code> wrapper they use, love and assign shortcut keys to, why don't we share our favourite ones.

A more pretty/informative Var_dump alternative in PHP?

GitHub

HTML5

JSON

每个不错的PHP程序员都有他们使用的print_r或var_dump包装器，他们喜欢并为其分配快捷键，为什么我们不分享我们最喜欢的。
