SugarCRM 7 is only approved for PHP Version 5.3. If you run PHP 5.4 or 5.5 in your development system and need to install Sugar, you'll have to hack a core file to get it to run. Note that SugarCRM is not officially supported on PHP 5.4 or 5.5, but in my experience, it seems to run well enough.

install_hack_utils.php

<?php
# /include/utils.php
# line 2980 opens function check_php_version
# just make it return 1

function check_php_version($sys_php_version = '')
{
    return '1';
    ...
}
