Coalesce is a function in Laravel that allows you to set a default value if a given value is null. Here is an example of how to use coalesce in Laravel:

  1. First, make sure you have Laravel installed and set up.
  2. Open your Laravel project in your preferred code editor.
  3. Locate the file or function where you want to use coalesce.
  4. Use the coalesce function to set a default value if a variable is null. The syntax of the coalesce function is coalesce($variable, $default). Here, $variable is the variable you want to check for null, and $default is the default value you want to set if the variable is null. For example, let's say you have a variable $name that may or may not have a value. You can set a default value of "Unknown" if $name is null using the coalesce function like this: $name = coalesce($name, "Unknown");
  5. Continue with your logic or output using the variable $name knowing that it will always have a value, either the original value or the default value you set.


That's it! You have successfully used coalesce in Laravel to set a default value if a variable is null.
