#9 Krumo CAN show the name of the passed variable

[Jawad]

With this little piece of code found on http://fr3.php.net/manual/en/language.variables.php :
function var_name(&$var, $scope=0)
{
$old = $var;
if (($key = array_search($var = 'unique'.rand().'value', !$scope ? $GLOBALS : $scope)) && $var = $old) return $key;
}

I would be happy to help in Krumo's development if you need help.

I made a simply modification, so a description to the variable is shown.

In class.krumo.php I changed:
1. Function dump($data, $name = '...')

2. (about line 580)
<div class="krumo-root">
<ul class="krumo-node krumo-first">
<?php echo krumo::_dump($data, $name);?>

Now I call: krumo( $variable, 'variable' );

I think, this solution will have some side effects. But If you are only using the call above, it should work. Nethertheless the idea is a good starting-point for easily extend krumo.

I had an other idea:
You know the file, you know the line, let's grep out the krumo call of the php file.

$varname=exec('sed -n -r \''.$d['line'].' s/.+krumo\((\$.+)\);/\1/ p\' '.$d['file']);

For less precision, we could just print the calling line, and it could be done more simply with sed, awk, head | tail, grep, ...

Cons:
* need to be sure to have sed and of the options to send to sed (mine is GNU sed version 4.2.1)
* krumo function must not be renamed (or you must know the name and adapt the call)
* will write all the args for each box if krumo has been called with 2 vars. krumo($var1, $var2)
* will only write the last call if krumo has been called twice, once per var. krumo($var1); krumo($var2);

Hi guys,
I made a similar workaround too. You can find it here
https://sourceforge.net/tracker/?func=detail&aid=3022585&group_id=194198&atid=948468
(there's a ready modified class)

Basically it's the same idea issued by ppir .
However I'm using it since last year and I did't notice any side effect.

I'm curios to hear what do you think about it.
cheers,
G

I just benchmarked with your file and mine.

My current technique is $varname=exec("sed -n '$d[line] p' $d[file]");
For 1000 krumo calls, my file takes 3 s.
With your file, it takes 68 ms.

So exec(sed) is not performant at all (i could have guessed it).
