I know I can send sms through php using api or gateway.
But my question is how those websites send sms through our mobile no. How is this done.
Any help
SMS is fundamentally like email, it trusts the sender to be truthful about who they are sending from. I use clickatell to send SMS and in the early days - 2004/5 you could send an sms to anyone from anyone without any special permission, but they quickly shut this down for security reasons, you now have to register and prove your rights to send from a particular address.
Basically in order for you to do it you need to either sign up with a mobile provider or have an agreement with your sms provider to allow you to send sms from whoever you wish. There may be senders out there who are less strict in setting the sender.
They would communicate with a provider (possibly through a third party) also using an API of sort. One of the parameters they would pass is a source number. So when the SMS is sent there is header information saying it came from a specific number. It is possible to set this value to a text string too instead of a number. So the SMS might look to come from for example 'STACKOVERFLOW' instead of '12345678'.

In PHP if I save the users mobile number into my phpmyadmin database and want to push certain notifications to the users phone I would have to email them at that specified number. How would you go about determining the users carrier to email such as #vtext.com or #at&temail.com or #virginmobile.com ect. How would I determine the ending email to send to? I know there are sites online that can determine this already for you which I can possibly send a curl request to and fetch the carrier it displays on the screen but how do these sites specifically determine these carriers? If they can determine it so can I right? There must be a way?
Most carriers do not offer an email to SMS gateway, so you don't. Use a service designed for sending SMS instead. e.g. Twilio or Amazon Simple Notification Service.
I notice that a lot of websites like Facebook and GitHub allow you to reply to an email notification which then posts the reply back to the application using a unique Reply-To address. How does this work on the back-end? I searched a lot but, only found that people were using unique Reply-To addresses. That's understandable but, what do they use to receive these emails? Do these companies set up email servers? I am trying to build this using PHP.
A common method is to set unique message ID's in the outgoing email and then looking at the In-Reply-To header to see which email this was in reply to. That lets you match up your server application's messaging system to emails. For example, if you send an email that represents a help desk ticket with ID 1234, the Message-ID could be something like
ticket-1234#myserver
Then, in email clients that work nicely (I'm looking at you Android), when you hit Reply, the reply has the header In-Reply-To: ticket-1234#mysever. You can go further by adding security tokens to ensure people can't forge messages (e.g. ticket-1234-hf29e9f2gf2e9fh29f#myserver). That security token is generated on the server when you send your first message and is then confirmed in the reply.
This normally works but can cause real headaches when email clients don't behave as they should!
This is how GitLab manages emails by using an identifier in the email address itself and catching it when the user replies. Although it is not relevant to any scripting language like PHP and uses server configs, this is what backend servers do to support reply by email functionality.
You have to set up a mail server to receive mail answers.
SIEVE filters on a IMAP server could be use to make some actions when a certain filter is detected.
But you can't only use PHP to make that type of system.
This specific example is using AT&T as the carrier of the receiver.
When sending SMS messages to clients via their carrier email address (1234567890#txt.att.net) from a static email address, the messages arrive on the phone from a number in the format of 1 (400) 000-244. Every time a new SMS message is sent, that number changes slightly. This causes phones, such as the iPhone, from properly threading the SMS messages that are coming from the same source email address.
Basic research shows that this has something to do with how AT&T's gateway handles turning emails into SMS messages. We've also looked at and decided that Common Short Codes (CSC) are not worth $1000 per month to purchase, so this is not an option for us.
Does anyone know of another way around this limitation in which it would be possible to force all SMS messages from the same source email to appear that way on the phone so that they are threaded correctly?
In our configuration, the emails are going out via SMTP using the PHP PEAR Mail_Mime package. We're really looking for a way we can do it on our end without the purchase of a shared or dedicated CSC.
Use:
<10 digit phone number>#mms.att.net
Instead of 'txt.att.net'
This will solve the short code dilemma.
For your AT&T issue they use a cluster model to send out SMS using the email gateway. To over come your problem there might be a couple of solutions but it all depends on what your needs are looks like they increment the phone number by one for each new message. Not sure how you could thread these.
Zeep Mobile lets you send SMS with a shared Short Code but they tag the end of your SMS message with ads, but the service is free (limited text per month I think)
Twilio might be a good cheap alternative as they offer such services. No short code but I believe they use the same From number for your threading issue.
Using your own GSM Modem could be an option but there is some work on getting this to work properly. Also it uses a Long Code (Think telephone number) instead of a Short Code.
There are a couple of other solutions so I will update my answer soon.

I have been asked to design a website for a client but one of the requirements is that there is a form which includes such things as name, email, dob and mobile number once the user submits the form a SMS is automatically sent to the users mobile almost like a autoresponder.
How to achieve this?
This can be done using an external SMS gateway which will not be free, but also not awfully expensive.
However, you say you are not a programmer. For this to be built well and most important of all, safely, it might be a good idea to use the services of one.
If you want to do it yourself, consider using a pre-paid plan with the SMS provider of your choice so you can't be ruined by a bot flooding your form with thousands of requests.
Web sms functionality can be added to any web application or website. As #Pekka said you need to use an external SMS gateway and to connect your application to this SMS Gateway. Most SMS gateways provide external API which can be used to do that. They usually have documentation which you can use to find out how to integrate SMS notification in your PHP code. Unfortunately there are no reliable free sms service provides so you have to pay for this sms service. You can check http://www.phpjabbers.com/web-sms/ which seems to work a lot easy. Their integration code is pretty simple:
<?php
$SMSLIB["phone"] = '44111222333'; // your phone number
$SMSLIB["key"] = 'abcdefghijklmnopqrs'; // your personal API code
include("smslib.php"); // we will provide you with smslib.php file
sendSMS("test message", $SMSLIB["phone"]); // function which sends the message
?>
The easiest way to do this is to send it to their mobile numbers assigned email address (which is different by each carrier) then have it sent like a normal email.
The only issue is you will probably have to have a Dropbox with each carrier then add something to the PHP that changes the email address (ex. $tmobile would be tmomail.net).

Does anyone know how can i send a sms messsage when e-mails are arriving in a gmail account?
I know some PHP, C/C++ and C#, and I plan to read the new message using POP3. The problem is that I don't know how can I send a SMS message to a mobile phone. Do I need a SMS server?
can you give me some advices?
you need to register with and buy credit at some bulk SMS gateway with API. personally, i would recommend: http://www.clickatell.com/
which allows to send SMS via email, HTTP/GET/POST, REST, XML etc.
Many cell carriers have the ability to send SMS messages to an email address (ie yourphonenumber#telus.com). If you're sending to a specific mobile phone (for keeping an eye on your website, say), this would be something to look into, because it's free and simple. For the general case of sending an SMS to any mobile phone, that's somewhat more complicated. You can either hook into an SMS gateway (such as clickatell, as dusoft mentions), or you can attach a GSM modem to your PC and send commands through it.
