Trim array print_r?

[EchoFool]

Hey

 

 

Is there a way to trim the print_r($array); so its completed and void of white space?

 

 

It prints like this:

 

 

 

Array
(
    [0] => Array
        (
            [id] => 10
            [f] => data/tiles/image.png
        )
)

 

 

But I want it to be compressed like this:

 

 

Array([0]=>Array([id]=>10[f]=>data/tiles/image.png))

This is then to be stored in the database, so any compressed possible is a plus in this situation.

 

 

Any ideas?

You can do a regex replace of white-space.  Though that'd remove it from any string values if you have them.

$out = print_r($arr, true);
$out = preg_replace('/\s+/', '', $out);

 

edit:

why are you storing the output of print_r in a database?

Yeh its fine if it removes them from strings!

 

Thanks for the info! : )

May I ask why you'd store that in a database, instead of just storing it serialized?

[EchoFool]

Well i store it as an array then load it then json_encode it for javascript. I've not heard of serialized before?

PHP has serialize and unserialize functions that will convert variables to/from string form.  In your case though, why not just json_encode the array and store that in the database?
