This worked for me.

/**
 * return phpinfo() results as an array
 *
 * @credit http://php.net/manual/en/function.phpinfo.php#106862
 * @param void
 * @return array
 */
function phpinfo_array(){
    ob_start();
    phpinfo();
    $info_arr = array();
    $info_lines = explode("\n", strip_tags(ob_get_clean(), '<tr><td><h2>'));
    $cat = 'general';
    foreach($info_lines as $line){
        preg_match('/<h2>(.*)<\/h2>/', $line, $title) ? $cat = preg_replace('/\s+/', '_', strtolower(trim($title[1]))) : null;
        if(preg_match('/<tr><td[^>]+>([^<]*)<\/td><td[^>]+>([^<]*)<\/td><\/tr>/', $line, $val)){
            $subcat = preg_replace('/\s+/', '_', strtolower(trim($val[1])));
            $info_arr[$cat][$subcat] = $val[2];
        } elseif(preg_match('/<tr><td[^>]+>([^<]*)<\/td><td[^>]+>([^<]*)<\/td><td[^>]+>([^<]*)<\/td><\/tr>/', $line, $val)){
            $subcat = preg_replace('/\s+/', '_', strtolower(trim($val[1])));
            $info_arr[$cat][$subcat] = array('local' => $val[2], 'master' => $val[3]);
        }
    }
    return $info_arr;
}


// output proper response code
$phpinfo = phpinfo_array();
$configure = (@isset($phpinfo['general']['configure_command'])) ?: null;

// properly account for FastCGI
if ($configure && preg_match('/--enable-fastcgi/', $configure)){
    // fastcgi response
    header('Status: 403 Access is forbidden');
} else {
    // http response
    header('HTTP/1.0 403 Access is forbidden');
}

php_sapi_name() or PHP_SAPI, both work.

http://php.net/manual/en/function.php-sapi-name.php

<?php
    if (php_sapi_name() != 'cgi-fcgi'){
        echo 'I knew fastcgi wasn\'t working.';
    }else{
        echo 'Holy crap, something worked for once.';
    }
