If you want to check if the variable exists, use isset otherwise use empty if the variable will always be set and you want to determine if its value is falsey.
How check variable is NULL or not in laravel? The is_null() function checks whether a variable is NULL or not. This function returns true (1) if the variable is NULL, otherwise it returns false/nothing.
The IS NOT NULL condition is used in SQL to test for a non-NULL value. It returns TRUE if a non-NULL value is found, otherwise it returns FALSE. It can be used in a SELECT, INSERT, UPDATE, or DELETE statement.
You can either use
null coalescing operator: {{ $material_details ?? 'second value' }}
or elvis operator: {{ $material_details ?: 'default value' }}
(checks given value is empty or null)
Read on Elvis and Null coalescing operator.
