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

By John Koster

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}
