Laravel Miscellaneous Helper Function: value

value($value)

The value function will return the default value of the supplied $value. Although this sounds redundant, if the supplied $value is an instance of the Closure class, the function will be executed and the value will be returned. If the $value is not an instance of Closure, the value is simply returned.

Using value with an instance of Closure:

1<?php
2 
3$value = value(function()
4{
5    return 42;
6});

In the above example, $value would contain the integer 42, because it was returned from the function.

The following example does not use an instance of Closure:

1<?php
2 
3$value = value(42);

Again, $value would contain the integer 42.
