Sending “var_dump” to FireBug console

Question

As you know var_dump() in addition to value show its data type and length.

Is there any way to log its output to

Answer 1

From: http://sixrevisions.com/web-development/how-to-debug-php-using-firefox-with-firephp/ Fb::log($array, "dumping an array") That will get you the type and data. You'll have to do extra logging manually for length/count.

Answer 2

You can dump JavaScript to the console by putting a console.log() in a script tag:

<script type="text/javascript">
console.log("hello");
</script>

So if you do a php dump in there...

<script type="text/javascript">
console.log("<?php var_dump('abc'); ?>");
</script>

You just need to be careful about ' and " in the var_dump breaking your JavaScript. In this example it will be ok because the HTML would be:

<script type="text/javascript">
console.log("string 'abc' (length=3)");
</script>

Just remember the php is processed then put in the JavaScript. You could also dump it to a comment:

<!--
<?php 
var_dump('abc');
?>
-->

Then you can view source, or inspect element.

Answer 3

<script>console.log( <?= json_encode( $var ) ?> )</script>

Just throwing my hat in the ring. It sounds like FirePHP is the best way to go.

Answer 4

if you just want to see the var_dump out put in the firebug (client side) without doing any things in Javascript I would recommande using cookies following is an illustration how you can perform it that way:

<?php
$str =  "Abu Romaïssae";

sendVarDumpToFront($str);

echo "<pre>";
echo $str."\n";

function sendVarDumpToFront( $mixed ){
    ob_start();
    var_dump($mixed);
    $content = ob_get_contents();
    ob_end_clean();
    setcookie("var_dump",$content);
}

than you can have it in firebug this way:

IMPORTANT

since this way uses cookies you will have to put the var_dump content before outputing any content otherwise this will not work

FirePHP does the job well + you can use it while you're developing Ajax.

Sample code:

require_once('FirePHPCore/fb.php'); # add the library

fb($var); #log the variable
fb( var_export($var,true) ); # log the variable with the var_export format

If you're passing an array to it, you can click it from your console and it will open a popup on your screen. You can even expand/collapse arrays and objects.

EDIT: If you're looking for data types and length, use var_dump().

fb( var_dump( array(
    1,
    'a',
    true
  ) ) );

I think one easy way to achieve this goal is to do a simple

console.log(<?php var_export($var, true) ?>);
