Creating Text as Image using PHP

You can simply represent a text as image using PHP by simple following program.

$text = "Hello World! Hows You???";
$textlLength = strlen($text);
$fontSize = 5;

/* imagefontheight() returns the pixel height of a character in specified font. */
$imageHeight = imagefontheight($fontSize);

/* imagefontwidth() returns the pixel width of a character in specified font. */
$imageWidth = imagefontwidth($fontSize) * $textLength;

/* imagecreate() returns an image identifier representing a blank image of specified size. */
$image = imagecreate($imageWidth, $imageHeight);

/* imagecolorallocate() allocated colour to an image */
imagecolorallocate($image, 255, 255, 255);
$fontColor = imagecolorallocate($image, 0, 0, 0);

/* imagestring() draws a string horizontally at given co-ordinates. */
imagestring($image, $fontSize, 0, 0, $text, $fontColor);

/* imagejpeg() creates a jpeg file from given image. */

Implementing Client Side WebRTC using Sipml5 javascript

Step 1:

Download and require Sipml5 library function.

Step 2:

Initialize sipml5 Engine in your web page :

var readyCallback = function(e) {
// function called when sipml is successfully initialised.
createSipStack(); // calling this function to create sip stack(see below)

var errorCallback = function(e) {
// function called when error occured during sipml initialisation.

SIPml.init(readyCallback, errorCallback);

Step 3:

Create Sip Stack :-
Sip Stack is an object that must be created before making/receiving call and sms. Creating Sip stack is an asynchronous process, so you need to create an event listener function to get state change notification.

var sipStack;

function EventListener(e) {

* e.type ;type of event listener
* e.session ; current event session
* e.getSipResponseCode() ; event response code
* e.description ; event description

if(e.type == 'started'){
// successfully started the stack.
} else if(e.type == 'i_new_call'){
// when new incoming call comes.
