以下是我在普通 PHP 项目中实际使用的代码 sn-ps,这些代码 sn-ps 用于各种框架的良好特性和最佳实践。
1。
下面的代码是用来检查你工作的环境,根据环境可以设置一些全局变量,报错等等。
if(!defined('ENVIRONMENT')){
define('ENVIRONMENT','DEVELOPMENT');
}
if (defined('ENVIRONMENT'))
{
switch (ENVIRONMENT)
{
case 'DEVELOPMENT':
case 'TESTING':
$base_url = 'http://localhost/project_name/';
error_reporting(E_ALL);
break;
case 'PRODUCTION':
$base_url = 'http://hostname/project_name/';
error_reporting(0);
break;
default:
exit('The application environment is not set correctly.');
}
}

/* This function is used to PRINT the ARRAY data in the pre formatted manner */
if (!function_exists('pr')) {
function pr($data) {
echo '<pre>', print_r($data), '</pre>';
}
}
3.
/* This function is used to Sanitize the user data and make data safe to insert into the database */
function sanitize($data) {
global $link;
$data = trim($data);
return htmlentities(strip_tags(mysqli_real_escape_string($link, $data)));
}
4.
/* Used to get the difference of 2 arrays
Returns the array with difference
*/
function multi_diff($arr1,$arr2){
$result = array();
foreach ($arr1 as $k=>$v){
if(!isset($arr2[$k])){
$result[$k] = $v;
} else {
if(is_array($v) && is_array($arr2[$k])){
$diff = multi_diff($v, $arr2[$k]);
if(!empty($diff))
$result[$k] = $diff;
}
}
}
return $result;
}
5.
/* This fnction is used to generate the random keys of specific length
Accepts parameter of certain length if not specified it will generate 20 bit length automatically
*/
function generate_random_key($length = 20) {
//Initializing the varialble
$keystring = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz1234567890';
$random_key = '';
for ($i = 0; $i < $length; $i++) {
$random_key.=$keystring[rand(0, strlen($keystring) - 1)];
}
//Return the randomly generated key
return $random_key;
}
6.
/* This function outputs the errors in ul>li format with unstyled
* To get the bullets styling remove class='list-unstyled' in <ul> tag */
function output_errors($errors){
$output = array();
foreach ($errors as $error) {
$output[] = '<li>'.$error.'</li>';
}
return '<ul class="list-unstyled">'.implode('', $output).'</ul>';
}
7.
/* Checks whether the user is loggedin else will redirect to the protectect page */
function protected_page(){
if(is_loggedin() === false){
// header('Location: protected.php');
header('Location: logout.php');
exit();
}
}
8.
/* If user tries to access the page directly accessing through the URL,
* If already loggedin then redirect him to any of the inner page
*/
function login_redirect(){
if(is_loggedin() === true){
header('Location: home.php');
}
}
9.
/* This function is used to check whether the user exists or not */
function email_exists($email){
/* Your Code */
}
/* This function is used to check whether the user isActive or not */
function is_active($email){
/* Your Code */
}
/* This function will get the userid from the email */
function userid_from_email($email) {
/* Your Code */
}
/* This fucntion is used to login the user based on the email-id and password */
function login($email,$password){
/* Your Code */
}
/* Check whether the USER is loggedin or not */
function is_loggedin(){
return (isset($_SESSION['userid'])) ? true : false;
}
