[SalesForce] Sending data from PHP to Salesforce using CURL

I have to send the data from PHP to Salesforce and save the data in Salesforce. I have tried with the following code:

$curlurl    = "https://www.mysalesforce.com/services/apexrest/Contact?email={$email}&lastname={$lastname}&firstname={$firstname}&telephone={$telehone_number}&phone={$phone_number}&title={$title}&companyname={$companyname}";
$params     = "&grant_type=refresh_token&client_id={$id}&client_secret={$secret}&username={$username}&password={$password}&refresh_token={$token}";
$ch         = curl_init( $curlurl );  

curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, 0 );   
curl_setopt( $ch, CURLOPT_SSL_VERIFYHOST, 0 );   
curl_setopt( $curl, CURLOPT_HEADER, $params );
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );                                                               
curl_setopt( $ch, CURLOPT_CUSTOMREQUEST, "POST" );                                                                     
curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, true );

$json_value = curl_exec( $ch );
$info       = @curl_getinfo( $ch );

print_r( $info );

if( FALSE === $json_value ) {
    //post failed
    die( curl_error( $ch ) );

} else {
    echo "Response {$json_value}";
}

curl_close( $ch );

In return when I send the data I'm getting a response like this:

Array (
    [url]                       => https://mysalesforce.com/services/apexrest/Contact?email=asd@123.cox&lastname=asd&firstname=asd&telephone=1234567890&phone=1234567890&title=asd&companyname=asd

    [local_port]                => 2940
    [redirect_url]              =>
)

Response[{
    "message"   : "Session expired or invalid",
    "errorCode" : "INVALID_SESSION_ID"
}]

HTTP - Code 401 states that:

The request requires user authentication. The response MUST include a WWW-Authenticate header field (section 14.47) containing a challenge applicable to the requested resource

Seems like you are not authenticating properly before making the callout to create the records in salesforce. Looking at your code, you need to obtain an access token which you need to pass in your request headers which will allow you access in order to be able to start making subsequent callouts.

Here is a good example of how to configure oAuth 2.0 for PHP integration with Salesforce. Also have a read here and here
