Question

What wrong with the following code?

WHen I tried to run the linter, it give me:

# PHP Parse error:  syntax error, unexpected '}' in test.ph on line 19

<?php

   function foo()
    {

        return function() 

        {
            print 'bar';
        }    
    }

Answer 1

The return expression needs to end and have a correct syntax.

// correct syntax
return EXPRESION;

// your function
function foo()
{
    return function()
    {
        print 'bar';
    }; // You need to add a semicolon.
}
