Laravel Eloquent Mutators and Accessors allows you to transform Eloquent attribute values when you retrieve or set them on model instances.

Laravel Eloquent Mutators and Accessors is of the Eloquent ORM in the Laravel web framework.

In Laravel, mutators and accessors allow you to alter data before it's saved to and fetched from a database.

Basically through mutators you can alter data before it saved to database and through accessor allows you to alter data after it's fetched from a database. To define an accessor, create a get{Attribute}Attribute method on your model where {Attribute} will be your table column name will be like for example you have first_name as column name then it accessors will be getFirstNameAttribute() and mutators will be setFirstNameAttribute().

First we will create custom class file inside laravel project app/Classes If Classes folder doesn't exist inside app folder then create it manually.

Second step is to create your class file, I have created like SendSms.php inside your app/Classes folder.

Third step define your class code.

Finally you have created your custom class now how to access custom class method.?

Define use App\Classes\SendSms; on the top of your controller.Then only you can able to access custom class method.

jQuery noConflict() method.

Bhanu Pratap Singh — Wed, 12 Feb 2020 06:30:07 +0000

What is noConflict()
noConflict() is an inbuilt function in jQuery by which you can resolve conflict situation when you use multiple JavaScript frameworks/libraries.

Why we use noConflict()
As we know we use $ sign in jquery for defination and for single project we also other JavaScript libraries and frameworks like ReactJs,Angular,Knockout etc.What if other JavaScript frameworks/libraries also use $ sign.?
In that case one of them might not work as excepted so to overcome this situation jQuery introduce noConflict() method.

Basically noConflict() method releases the hold on the $ shortcut identifier, so that other scripts can use it.
