How to fix laravel 5.2 this error "Maximum function nesting level of '100' reached, aborting!"?

Issue is caused by default xdebug.max_nesting_level which is 100.

The workaround for now is to increase xdebug.max_nesting_level to a certain level say 200 or 300 or 400.

I fixed mine by increasing xdebug.max_nesting_level to 120, by adding the line below to bootstrap/autoload.php in the Laravel 5.1

ini_set('xdebug.max_nesting_level', 120);

............

define('LARAVEL_START', microtime(true));

This usually happens because you are loading the relations from the two models at once by something like $with property.

Let's say a Category hasMany Product and a Product belongsTo a Category.

If in both models you load the relations by default like this: in Product model $with=['category'], in Category model $with=['products']

This would result this infinite nesting. So, to solve this load the relations whenever wanted only.

Also this could happen with GlobalScopes and the idea is similar to $with property.

In my case, I accidentally assigned the same name to both a class method and an imported trait resulting in a loop of $this->doThis() --> $this->doThis() --> $this->doThis() --> $this->doThis()...
