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

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.

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));

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()...
