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:
- First, make sure you have Laravel installed and set up.
- Open your Laravel project in your preferred code editor.
- Locate the file or function where you want to use coalesce.
- 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");
- 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.
