How to Send Email in PHP Using PHPMailer Library

Aj is article me ham parhen gen ke PHP me mail "PHPMailer" library ko use krte hue kis tarah bheji jati hay aur PHP ka built-in function mail() q nh use krna chaiye.

PHP me mail kis tarah bheje jate hain usko samajhne se pehle hamen ye samajhna hoga ke jab ham kisi ko koi email bhjte hain to wo email kis tarah se process hokar receiver ke pas pounchta hay.

What is SMTP:

Jab bhi ham kisi ko koi mail bhjtey hain to receiver ke pas email ek protocol follow krte hue ata hay, Aur is protocol ko ham SMTP (Simple Mail Transfer Protocol) kehte hain.

Jese hi ham kisi ko mail bhjtey hain to wo mail pehle ek server ke pas jata hay jo is SMTP protocol ko follow krta hay isliye ham usey SMTP server kehte hain, Ye server phir receiving end ke SMTP server ke pas mail ko bhjta hay aur phir receiver is SMTP server se mail receive krta hay.

PHP Mail Function:

PHP me hamare pas ek built in function hay jis ke through kisi ko bhi mail send krskte hain, Example dekhen.

1.  <?php  

2.      $to="abc@gmail.com";  

3.      $sub="This is Subject";  

4.      $messg="This is Messege Body";  

5.      mail($to,$sub,$messg);  

6.  ?>  

Code self explanatory hay, simply ham mail function me jis email per mail bhjna hay uska address then subject and then apna message pass krte hain, Additionally ham is me headers bhi pass krskte hain, Header extra information hoti hay mail ke bare me.

Lekin Jab is code ko execute karen gen to apke pas pehle to foran se mail nh ae ga balke ap ko wait krna parega, Dusra mail bhi spam folder me aega, Iski waja kia hay?

Iski waja hay ke PHP mail function ek to apka locally SMTP server use krta hay mail bhjne ke liye, Agar ap locally chala rhe hain apna code to Xampp me mojud local SMTP server aur agar hosting per apka code hay to hosting ka SMTP server aur mostly mail service locally ya hosting servers ko blacklist krdeti hay, Uski waja hay ke SMTP server bohat sari security policies ko follow nh krta isliye mostly mail services hamare server ki IP addres ko blacklist krdeti hain aur phir mail function use krne se  security mazeed kharab hojati hay q ke mail function ko easily spam purpose ke liye use kia jsakta hay.

Ab jese hi ham code execute karen gen to pehle to hamare SMTP server se gaye mail ko dusri mail services accept nh karen gen, response me hamara server continuously mail send krne ki koshish kare ga aur finally dusra mail server hamari request accept to krle ga lekin wo mail ko spam folder me dal dey ga.

Iska ek to hal yeh hay ke ham complex headers use krke apne mail function ko kuch had tak secure banae, Lekin developer ne iska haal pehle se hi bana kr muktalif libraries ki surat me hame de diya.

Ek aur waja PHP mail function ko na use krne ki ye bhi hay ke ye function hamari ziada kuch madad nh krta agar hamen koi attachment mail ke sath bhjni hay etc.

PHP libraries ko banane ka maqsad yehi hay k ek to security ko improve kia jae take dusri mail services hamare mail ko accept karen, Isi tarah agar hamen mail me attachment wagera bhjni hay to us ke liye PHP libraries ne kam asan krdiya.

PHP se mail send krni ki bohat sari libraries hain aur sab se popular library hay “PHP Mailer”.

PHP Mailer:

PHPMailer php ki ek popular mail library hay jis ke through ham complex kam ko bari asani ke sath krskte hain.

Ye library complex headers ko backend per khud manage krti hay jis ki madad se mail services ke hamare mail accept krne ke chance barh jate hain.

Lekin bat yahan per khatam nh hoti, Ab jesa ke bataya hay ke security reasons ki waja se locally ya shared hosting ke mostly SMTP servers blacklisted hote hain, To ab ek tarika to yeh hay ke ham headers ko propely format karen, Lekin kia hi bat ho agar ham Google ke SMTP server ko apna mail send krne ke liye use karen !

Google hamen ye service provide krta hay ke ham uske Gmail ke SMTP server ko use krskte hain apna mail bhjne ke liye aur is kam ko mazeed asan krdiya hay PHPMailer library ne.

Google kay SMTP server ko use krne ka ye faida hoga ke Google ka SMTP for sure blacklisted nh hay aur na hi security vulnerabilities hain, jiska matlab dusri mail services easily hamare mail ko accept krlen gen !

To is library ko install aur configure krne ke liye Github me iski repository me mojud readme file me mojud instructions ko read karen.

Ab ham simply basic example dekhte hain ke kis tarah is library ke use krte hue ham Google ke SMTP server ke zariye kisi bhi mail service per mail bhj skte hain

1.  <?php  

2.        

3.      //Import PHPMailer classes into the global namespace  

4.      use PHPMailer\PHPMailer\PHPMailer;  

5.        

6.      require '../vendor/autoload.php';  

7.        

8.      //Create a new PHPMailer instance  

9.      $mail = new PHPMailer;  

10.       

11.     //Tell PHPMailer to use SMTP  

12.     $mail->isSMTP();  

13.       

14.     //Enable SMTP debugging  

15.     // 0 = off (for production use)  

16.     // 1 = client messages  

17.     // 2 = client and server messages  

18.     $mail->SMTPDebug = 2;  

19.       

20.     //Set the hostname of the mail server  

21.     $mail->Host = 'smtp.gmail.com';  

22.     // use  

23.     // $mail->Host = gethostbyname('smtp.gmail.com');  

24.     // if your network does not support SMTP over IPv6  

25.       

26.     //Set the SMTP port number -

27.     $mail->Port = 587;  

28.       

29.     //Set the encryption system to use - ssl (deprecated) or tls  

30.     $mail->SMTPSecure = 'tls';  

31.       

32.     //Whether to use SMTP authentication  

33.     $mail->SMTPAuth = true;  

34.       

35.     //Username to use for SMTP authentication - use full email address for gmail  

36.     $mail->Username = "username@gmail.com";  

37.       

38.     //Password to use for SMTP authentication  

39.     $mail->Password = "yourpassword";  

40.       

41.     //Set who the message is to be sent from  

42.     $mail->setFrom('from@example.com', 'First Last');  

43.       

44.     //Set an alternative reply-to address  

45.     $mail->addReplyTo('replyto@example.com', 'First Last');  

46.       

47.     //Set who the message is to be sent to  

48.     $mail->addAddress('whoto@example.com', 'John Doe');  

49.       

50.     //Set the subject line  

51.     $mail->Subject = 'PHPMailer GMail SMTP test';  

52.       

53.     //Mail message  

54.     $mail->Body = 'This is a plain-text message body';  

55.   

56.     //send the message, check for errors  

57.     if (!$mail->send()) {  

58.         echo "Mailer Error: " . $mail->ErrorInfo;  

59.     } else {  

60.         echo "Message sent!";  

61.   

62.   

63.     }  

64. ?>  

Mostly code self  explanatory hay, Lekin kuch cheezen hain jinka me bata deta hn.

1.      $mail->Host = 'smtp.gmail.com';  

Is ke through ham apni library ko bata rhe hain ke mail ko  bhjne ke liye Google ka SMTP server use kia jae.

1.  //Username to use for SMTP authentication - use full email address for gmail  

2.      $mail->Username = "username@gmail.com";  

3.        

4.      //Password to use for SMTP authentication  

5.      $mail->Password = "yourpassword";  

    

Ab yahan uper hame apni koi gmail Id aur uska pass dena hoga, Q ke Gmail ka SMTP server authentication ke liye ye details use kare ga, Agar ap Gmail Id aur Password nh lagna chate then ap XOAuth authentication bhi use krskte hain, Jis me apko client id aur client secret likhna hoga username aur password ki jaga.

Agar apko Gmail ka SMTP server use nh krna balke khud ka locally server use krna hay then ap wo kam bhi is library ke through krskte hain, Github per iski muktalif examples mojud hain.  

Conclusion:

PHPMailer library ko use krne ka faida yeh hoga ke apke pas email ki jis tarah normal delivery hoti hay wese hi hogi koi delay nh hooga, Similarly apko complex headers  likhne ki zarort nh, Backend per ye library wo sara kam khud krdey gi.
