Laravel 5: Checking if a Variable Holds a Value With filled

The filled helper function is the logical opposite of the blank helper function, and can be used to quickly determine if the provided value has a non-null, or non-empty value. The provided $value is considered filled if any of the following conditions are met:

• The value is not null,
• The value is a string and contains non-whitespace characters with a length greater than 0,
• The value is numeric, and contains value,
• The value is boolean,
• The value is a Countable object and contains items,
• the PHP empty evaluates to false

#Signature

The signature of the filled function is:

1function filled(
2    $value
3);

#Example Use

The following example demonstrates the basic usage of the filled method and is the opposite of the example provided in the blank section:

 1// Set a value to null.
 2$testValue = null;
 3 
 4if (filled($testValue)) {
 5    // Perform some action when the
 6    // supplied value is not 'blank'.
 7} else {
 8    // Perform a different action when the
 9    // supplied value is 'bank'.
10}
