Description:
------------
Using the following snippet, I get the correct response:

    var_dump(file_get_contents('my_local_file')); //Prints file contents
    fopen('my_local_file', 'r+');
    var_dump(file_get_contents('my_local_file')); //Prints file contents again

However, changing the mode in fopen to 'w+', causes weird behaviour:

    var_dump(file_get_contents('my_local_file')); //Prints file contents
    fopen('my_local_file', 'w+');
    var_dump(file_get_contents('my_local_file')); //Prints an empty string

Error is reproductible in PHP 5.6.

Test script:
---------------
    <?php
    var_dump(file_get_contents('my_local_file')); //Prints file contents
    fopen('my_local_file', 'w+');
    var_dump(file_get_contents('my_local_file')); //Prints an empty string
