SoAs.in June 21, 2017 PHP

This post about "Sending Mail using SMTP and PHP". Now you can send emails with SMTP authentication using this script. Every mail needed server authentication, So you have to buy mail server. It's very useful you can implement this on your web projects.

This tutorial contains three files.

- Index.php
- SMTPconfig.php // SMTP Server Cofiguration
- SMTPClass.php // SMTP Mail Sending Class

SMTPconfig.php
You have to change SMTP server details.

<?php
//Server Address
$SmtpServer="127.0.0.1";
$SmtpPort="25"; //default
$SmtpUser="username";
$SmtpPass="password";
?>

SMTPclass.php
SMTP mail sending class.

<?php
class SMTPClient
{

function SMTPClient ($SmtpServer, $SmtpPort, $SmtpUser, $SmtpPass, $from, $to, $subject, $body)
{

$this->SmtpServer = $SmtpServer;
$this->SmtpUser = base64_encode ($SmtpUser);
$this->SmtpPass = base64_encode ($SmtpPass);
$this->from = $from;
$this->to = $to;
$this->subject = $subject;
$this->body = $body;

if ($SmtpPort == "")
{
$this->PortSMTP = 25;
}
else
{
$this->PortSMTP = $SmtpPort;
}
}

function SendMail ()
{
if ($SMTPIN = fsockopen ($this->SmtpServer, $this->PortSMTP))
{
fputs ($SMTPIN, "EHLO ".$HTTP_HOST."\r\n");
$talk["hello"] = fgets ( $SMTPIN, 1024 );
fputs($SMTPIN, "auth login\r\n");
$talk["res"]=fgets($SMTPIN,1024);
fputs($SMTPIN, $this->SmtpUser."\r\n");
$talk["user"]=fgets($SMTPIN,1024);
fputs($SMTPIN, $this->SmtpPass."\r\n");
$talk["pass"]=fgets($SMTPIN,256);
fputs ($SMTPIN, "MAIL FROM: <".$this->from.">\r\n");
$talk["From"] = fgets ( $SMTPIN, 1024 );
fputs ($SMTPIN, "RCPT TO: <".$this->to.">\r\n");
$talk["To"] = fgets ($SMTPIN, 1024);
fputs($SMTPIN, "DATA\r\n");
$talk["data"]=fgets( $SMTPIN,1024 );
fputs($SMTPIN, "To: <".$this->to.">\r\nFrom: <".$this->from.">\r\nSubject:".$this->subject."\r\n\r\n\r\n".$this->body."\r\n.\r\n");
$talk["send"]=fgets($SMTPIN,256);
//CLOSE CONNECTION AND EXIT ...
fputs ($SMTPIN, "QUIT\r\n");
fclose($SMTPIN);
//
}
return $talk;
}
}
?>

index.php

<?php
include('SMTPconfig.php');
include('SMTPClass.php');
if($_SERVER["REQUEST_METHOD"] == "POST")
{
$to = $_POST['to'];
$from = $_POST['from'];
$subject = $_POST['sub'];
$body = $_POST['message'];
$SMTPMail = new SMTPClient ($SmtpServer, $SmtpPort, $SmtpUser, $SmtpPass, $from, $to, $subject, $body);
$SMTPChat = $SMTPMail->SendMail();
}
?>
<form method="post" action="">
To:<input type="text" name="to" />
From :<input type='text' name="from" />
Subject :<input type='text' name="sub" />
Message :<textarea name="message"></textarea>
<input type="submit" value=" Send " />
</form>

PHP Login Page Example.

SoAs.in June 21, 2017 PHP

Are you looking for PHP login script, in this post I want to discuss how to create a simple PHP login with welcome page using MySQL database. This will explain you creating user tables, posting form values and storing and destroying the session values.

Database
MySQL admin table columns id, username, passcode.

CREATE TABLE admin
(
id INT PRIMARY KEY AUTO_INCREMENT,
username VARCHAR(30) UNIQUE,
passcode VARCHAR(30)
);

Config.php
Database configuration file.

<?php
define('DB_SERVER', 'localhost');
define('DB_USERNAME', 'username');
define('DB_PASSWORD', 'password');
define('DB_DATABASE', 'database');
$db = mysqli_connect(DB_SERVER,DB_USERNAME,DB_PASSWORD,DB_DATABASE);
?>

Login.php
Contains PHP and HTML code.

<?php
include("config.php");
session_start();
if($_SERVER["REQUEST_METHOD"] == "POST")
{
// username and password sent from Form
$myusername=mysqli_real_escape_string($db,$_POST['username']);
$mypassword=mysqli_real_escape_string($db,$_POST['password']);
$passwordSecure=md5($mypassword);
$sql="SELECT id FROM admin WHERE username='$myusername' and passcode='$passwordSecure'";
$result=mysqli_query($db,$sql);
$row=mysqli_fetch_array($result,MYSQLI_ASSOC);
$active=$row['active'];
$count=mysqli_num_rows($result);


// If result matched $myusername and $mypassword, table row must be 1 row
if($count==1)
{
session_register("myusername");
$_SESSION['login_user']=$myusername;

header("location: welcome.php");
}
else
{
$error="Your Login Name or Password is invalid";
}
}
?>
<form action="" method="post">
<label>UserName :</label>
<input type="text" name="username"/><br />
<label>Password :</label>
<input type="password" name="password"/><br/>
<input type="submit" value=" Submit "/><br />
</form>

lock.php
Session verification. If no session value page redirect to login.php

<?php
include('config.php');
session_start();
$user_check=$_SESSION['login_user'];

$ses_sql=mysqli_query($db,"select username from admin where username='$user_check' ");

$row=mysqli_fetch_array($ses_sql,MYSQLI_ASSOC);

$login_session=$row['username'];

if(!isset($login_session))
{
header("Location: login.php");
}
?>

welcome.php

<?php
include('lock.php');
?>
<body>
<h1>Welcome <?phpecho $login_session; ?></h1>
</body>

logout.php
SignOut Destroy the session value.

<?php
session_start();
if(session_destroy())
{
header("Location: login.php");
}
?>

URLs as Links with Regular Expressions using PHP Function.

SoAs.in June 21, 2017 PHP

I'm using this PHP function to redirect text URLs as Links with Regular Expression validation. Just five lines of code, It's very useful.

To_Link.php
Contains PHP Code $text value validating with Regular Expressions

<?php
function To_Link($text)
{
$text = html_entity_decode($text);
$text = " ".$text;
$text = eregi_replace('(((f|ht){1}tp://)[-a-zA-Z0-9@:%_\+.~#?&//=]+)',
'<a href="\\1">\\1</a>', $text);
$text = eregi_replace('(((f|ht){1}tps://)[-a-zA-Z0-9@:%_\+.~#?&//=]+)',
'<a href="\\1">\\1</a>', $text);
$text = eregi_replace('([[:space:]()[{}])(www.[-a-zA-Z0-9@:%_\+.~#?&//=]+)',
'\\1<a href="http://\\2">\\2</a>', $text);
$text = eregi_replace('([_\.0-9a-z-]+@([0-9a-z][0-9a-z-]+\.)+[a-z]{2,3})',
'<a href="mailto:\\1">\\1</a>', $text);
return $text;
}
?>

index.php
You have to include To_link.php. Using function To_Link('You Text and URL')

<?php
include('To_Link.php');

$text='jQuery and Ajax best 9lessons http://tinyurl.com/naottn';

echo To_Link($text);

?>

Analyzing URLs as Links to the resource using a PHP function.

SoAs.in June 21, 2017 PHP

This is PHP function split_url_fuction() writter for twitter like application that i am developing, useful to split URL from the updated sentence(posted message), then URL changing like tinyurl and link to the resource.

This function is break up the URL from the sentence, if the URL string length greater than 30 words it's change like TinyURL.

Step 1. You have to include the file split_url_function.php into the PHP file that will use the function.

include("split_url_function.php");

Now you have to pass the updated data:

<?php echo  split_url_function($message); ?>

Here $message is the value from a SQL query.( Table structure )

This is the code of split_url_funtion() PHP function:

<?php
include("tiny_url.php"); //tinyurl function
function split_url_function($update)   
{
    //----URL Checking in Update.
    $http= substr_count($update,"http://");
    $www=substr_count($update,"www.");
    $htp=substr_count($update,"http//");

    if($http==1)
   {
         $str="http://";
         $h=1;
    }
    if($www==1)
   {
      $str="www.";
      $w=1;
    }
    if($h==1 && $w==1)
    {
       $str='http://www.'; //--Both
    }
    if($htp==1)
    {
          $comb_str=$update; //--No url
     }
//--- explode the update 
$fa=explode($str,$update);
$cnt_fa=count($fa);
$se=explode(" ",$fa[1]);
$cnt_se=count($se);

for($i=1;$i<=$cnt_se;$i++)
{
     $sep.=$se[$i].' ';
}
     // Split URL 
      $split_url=$str.$se[0];
      if($split_url=='')
     {
         $final_update=$update;
      }
      else
    {
         // URL link sting lenght verfication
         if(strlen($split_url)>=30)
        {
             $tiny = tiny_url($split_url);
$final_update=$fa[0].'<a href="'.$tiny.'" target="_blank">'.$tiny.'</a>'.$sep;
echo $final_update;
         }
         else
        {
          // Combine all the explode parts
$final_update=$fa[0].'<a href="'.$split_url.'" target="_blank">'.$split_url.'</a>'.$sep;
echo $final_update;
         }
     }
}
?>

tiny_url.php Original reference http://davidwalsh.name/create-tiny-url-php

<?php
function tiny_url($url)
{
$ch = curl_init();
$timeout = 5;
curl_setopt($ch,CURLOPT_URL,'http://tinyurl.com/api-create.php?url='.$url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,$timeout);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
