# Maximum length of description is 6o characters. 
description = This is a sample PHP app for testing purpose

# The programming language , currently support python or php only
# If this is a Python Django app use python
# if this is a  PHP app chose , php
# Accepted values [ python , php]
language = php

# This app version number
version = 1.0.0

# The version_check_url is a remote url shows the available current version of the app
# This url must give the version number as plain text output
# This version should ensure if the app is up-to-date
version_check_url =  https://download.eenos.com/apps/sample-php-app/version.txt

# The auto update script path used to update the scripts
# You can place this in ,/scripts/ folder so that will be installed 
auto_update = /usr/local/eenos/scripts/samplephpapp_update

[wap]
# The general settings for WAP admin app

# Supported values ,[ on , off ]
status = on

# If you wish to open the app in new browser window during a click action

        return false;
    }
 }
Custom Preg 
<?php
 
function is_notsuspended($username){
    if (file_exists("/var/eenos/suspended/$username")){        
        return false;
    }else{        
        return true;
       
    }
}

function iseenosuer($username){
    if (file_exists("/var/eenos/users/$username")){        
        return true;
    }else{        
        return false;
    }
}

function sauthenticate($user, $pass){
    if (iseenosuer(($user))){
        if (is_notsuspended($user)){
        $shad =  preg_split("/[$:]/",`cat /etc/shadow | grep "^$user\:"`);
        if (!isset($shad[2]) || !isset($shad[3])) return false;
        $mkps = preg_split("/[$:]/",crypt($pass, '$'.$shad[2].'$'.$shad[3].'$'));         
        return ($shad[4] == $mkps[3]);
        }else{
            return false;
