Increase var_display_max_depth for xdebug

I recently installed xdebug on my ststem and wanted to increase xdebug.var_display_max_depth from 3 to 10. How can I go about doing that?

There are two ways to do that. You can edit this value locally and globally too.

Local setting ("Local value") in your own PHP file:

<?php  
    ini_set('xdebug.var_display_max_depth', '10');    
    // here comes your code...  
?>

Global setting ("Master value") in php.ini:
1. First locate your php.ini file. _{In phpinfo(), you can get to know where it is from "Loaded Configuration File" directive.
  You can also locate it using command prompt/terminal:
  
  Windows: php --ini | findstr /C:"Loaded Configuration File"
  Linux/UNIX-like: php --ini | grep 'Loaded Configuration File'
  
  using php_ini_loaded_file(): <?php echo php_ini_loaded_file(); ?>}
Open your php.ini in a text editor file.

You have to put something like the following to this file (in this example, I'm using php_xdebug-2.2.3-5.3-vc9-nts.dll _{(use http://xdebug.org/wizard.php to get to know which version you need)}), and of course, you need to substitute <path to your XDebug> to the appropriate path:

[Xdebug]  
;; <path to your XDebug> is like
;; C:\Program Files (x86)\PHP\v5.3\ext in Windows
;; (should be e.g. in PHP directory's "ext" subdir)
;; [backslash UNDER WINDOWS, / under UNIX-like operating systems]  
zend_extension = "<path to your XDebug>\php_xdebug-2.2.3-5.3-vc9-nts.dll"  

;; HERE comes the answer to your question, we set the mentioned variable to 10  
xdebug.var_display_max_depth = 10

Simple as that... you can check the results in phpinfo's xdebug part in a table: there will be a "Local value" and a "Master value" column.

Here's a sample screenshot from my localhost server; in this example, the global configuration is 3, but I set the local value to 10, with the above mentioned ini_set():

In addition to Sk8erPeter answer you can of course set it in your .htaccess file for faster management:

php_value xdebug.var_display_max_depth 10
