php var_dump() limits the number of levels

Problem:

php var_dump() limits the number of levels to three.

Solution:

This is the default setting of xdebug.

To change the default, edit your xdebug.ini file and add the folllowing line:
xdebug.var_display_max_depth=n

Ubuntu:

• sudo vi /etc/php5/conf.d/xdebug.ini
• or
• sudo vi /etc/php/7.0/mods-available/xdebug.ini

  • xdebug.var_display_max_depth = 15 

• sudo apache2ctl restart

Moreover:

• e.g. cut off string:

  • xdebug.var_display_max_data = 4096

• heavily nested:

  • xdebug.max_nesting_level = 200
