Hi Geeks,
In this tutorial we will learn that how to Create and save dynamic image in php using gd library or Text to Image Convert using php code . in this example we have a requirement to create a image with specific width and height and specific background and watermark also.
So that we have created a PHP Class to generate and save the image to specific folder or path.
please follow the steps to achive this task.
Step 1. Create a class file for generate image with name class.img.php with following code:

<?php
class IMG_PROCESS{

var $_font1="";
var $_font2="";
var $_font_size="";
var $_font_size_watermark="";

public function __construct($font_1,$font_2,$font_size="40",$font_size_watermark="15")
{
	$this->_font1=$font_1;
	$this->_font2=$font_2;
	$this->_font_size=$font_size;
	$this->_font_size_watermark=$font_size_watermark;
	
}

public function imagettftext_cr(&$im, $size, $angle, $x, $y, $color, $fontfile, $text)
{
	// retrieve boundingbox
	$bbox = imagettfbbox($size, $angle, $fontfile, $text);
	// calculate deviation
	$dx = ($bbox[2]-$bbox[0])/2.0 - ($bbox[2]-$bbox[4])/2.0;         // deviation left-right
	$dy = ($bbox[3]-$bbox[1])/2.0 + ($bbox[7]-$bbox[1])/2.0;        // deviation top-bottom
	// new pivotpoint
	$px = $x-$dx;
	$py = $y-$dy;
	return imagettftext($im, $size, $angle, $px, $y, $color, $fontfile, $text);
}

public function generate_img($name,$savepath,$size_arr,$watermark,$rgb=array("34","96","76"))
{
 
     
$image = imagecreate($size_arr['width'],$size_arr['height']);
$rgb_background = imagecolorallocate($image,$rgb[0],$rgb[1],$rgb[2]);
$grey_shade = imagecolorallocate($image,40,40,40);
$white = imagecolorallocate($image,255,255,255);


// Local font files, relative to script
$otherFont = $this->_font1;
$font = $this->_font2;

 
$i=0;
while($i<10){
$this->imagettftext_cr($image,12,$this->_font_size_watermark,rand(100,500),rand(200,500),$grey_shade,$otherFont,$watermark);
$i++;
}

// Main Text

$w=$size_arr['width'] / 2 ;
$h=$size_arr['height'] / 2 ;

$this->imagettftext_cr($image,$this->_font_size,0,$w,$h,$white,$font,$name);
$this->imagettftext_cr($image,$this->_font_size_watermark,0,$w,$h+30,$white,$otherFont,$watermark);
imagejpeg($image,$savepath);

}

}
?>

<?php

class IMG_PROCESS{

var $_font1="";

var $_font2="";

var $_font_size="";

var $_font_size_watermark="";

public function __construct($font_1,$font_2,$font_size="40",$font_size_watermark="15")

{

$this->_font1=$font_1;

$this->_font2=$font_2;

$this->_font_size=$font_size;

$this->_font_size_watermark=$font_size_watermark;

}

public function imagettftext_cr(&$im, $size, $angle, $x, $y, $color, $fontfile, $text)

{

// retrieve boundingbox

$bbox = imagettfbbox($size, $angle, $fontfile, $text);

// calculate deviation

$dx = ($bbox[2]-$bbox[0])/2.0 - ($bbox[2]-$bbox[4])/2.0; // deviation left-right

$dy = ($bbox[3]-$bbox[1])/2.0 + ($bbox[7]-$bbox[1])/2.0; // deviation top-bottom

// new pivotpoint

$px = $x-$dx;

$py = $y-$dy;

return imagettftext($im, $size, $angle, $px, $y, $color, $fontfile, $text);

}

public function generate_img($name,$savepath,$size_arr,$watermark,$rgb=array("34","96","76"))

{

$image = imagecreate($size_arr['width'],$size_arr['height']);

$rgb_background = imagecolorallocate($image,$rgb[0],$rgb[1],$rgb[2]);

$grey_shade = imagecolorallocate($image,40,40,40);

$white = imagecolorallocate($image,255,255,255);

// Local font files, relative to script

$otherFont = $this->_font1;

$font = $this->_font2;

$i=0;

while($i<10){

$this->imagettftext_cr($image,12,$this->_font_size_watermark,rand(100,500),rand(200,500),$grey_shade,$otherFont,$watermark);

$i++;

}

// Main Text

$w=$size_arr['width'] / 2 ;

$h=$size_arr['height'] / 2 ;

$this->imagettftext_cr($image,$this->_font_size,0,$w,$h,$white,$font,$name);

$this->imagettftext_cr($image,$this->_font_size_watermark,0,$w,$h+30,$white,$otherFont,$watermark);

imagejpeg($image,$savepath);

}

Step 2. make another php file with any name.
and include the class file as follow:

<?php
include 'class.img.php';//include class file for generate image
?>

<?php

include 'class.img.php';//include class file for generate image

Now create a instance of img class with font file names and sizes as following :

<?php
$font_file1="fonts/arial.ttf";
$font_file2="fonts/times.ttf";
$font_size="40";
$font_size_watermark="15";
?>

<?php

$font_file1="fonts/arial.ttf";

$font_file2="fonts/times.ttf";

$font_size="40";

$font_size_watermark="15";

Init with font files and font sizes as follow:

<?php
$img_obj=new IMG_PROCESS($font_file1,$font_file2,$font_size,$font_size_watermark);
?>

<?php

$img_obj=new IMG_PROCESS($font_file1,$font_file2,$font_size,$font_size_watermark);

Now generate a single image as follow:

<?php
	$text_to_image="THIS IS MY TEXT";//
	$size_arr=array("width"=>"500","height"=>"500"); //define height and width
	$savepath="images/my_image_test.jpg";
	$watermark="w3school test";
	$rgb=array("0","0","0");//define a black rgb scheme
	$img_obj->generate_img($text_to_image,$savepath,$size_arr,$watermark,$rgb); //call the generate image 
?>

<?php

$text_to_image="THIS IS MY TEXT";//

$size_arr=array("width"=>"500","height"=>"500"); //define height and width

$savepath="images/my_image_test.jpg";

$watermark="w3school test";

$rgb=array("0","0","0");//define a black rgb scheme

$img_obj->generate_img($text_to_image,$savepath,$size_arr,$watermark,$rgb); //call the generate image

Generate multiple images in loop as following code :

<?php
$text=array("MY IMAGE TEXT 1","MY IMAGE TEXT 2","MY IMAGE TEXT 3","MY IMAGE TEXT 4","MY IMAGE TEXT 5",);
foreach($text as $title)
{
	 
	//
	$img_name=strtolower(str_replace(" ","-",$title));
	$size_arr=array("width"=>"1366","height"=>"768"); //define height and width
	$savepath="images/".$img_name.".jpg";
	$watermark="w3school test watermark";
	$rgb=array("34","96","76");//define a light green rgb scheme
	$img_obj->generate_img($title,$savepath,$size_arr,$watermark,$rgb); //call the generate image function
	// 
 
	
}
?>

<?php

$text=array("MY IMAGE TEXT 1","MY IMAGE TEXT 2","MY IMAGE TEXT 3","MY IMAGE TEXT 4","MY IMAGE TEXT 5",);

foreach($text as $title)

{

$img_name=strtolower(str_replace(" ","-",$title));

$size_arr=array("width"=>"1366","height"=>"768"); //define height and width

$savepath="images/".$img_name.".jpg";

$watermark="w3school test watermark";

$rgb=array("34","96","76");//define a light green rgb scheme

$img_obj->generate_img($title,$savepath,$size_arr,$watermark,$rgb); //call the generate image function

}

Complete Code of above snippets:

<?php 
include 'class.img.php';//include class file for generate image

//now create a instance of img class with font file names and sizes as following 
$font_file1="fonts/arial.ttf";
$font_file2="fonts/times.ttf";

$font_size="40";
$font_size_watermark="15";

$img_obj=new IMG_PROCESS($font_file1,$font_file2,$font_size,$font_size_watermark); //init with font files and font sizes

//now generate a single image  

	$text_to_image="THIS IS MY TEXT";//
	$size_arr=array("width"=>"500","height"=>"500"); //define height and width
	$savepath="images/my_image_test.jpg";
	$watermark="w3school test";
	$rgb=array("0","0","0");//define a black rgb scheme
	$img_obj->generate_img($text_to_image,$savepath,$size_arr,$watermark,$rgb); //call the generate image 


//now generate a single image  

 


//generate multiple images in loop

$text=array("MY IMAGE TEXT 1","MY IMAGE TEXT 2","MY IMAGE TEXT 3","MY IMAGE TEXT 4","MY IMAGE TEXT 5",);
foreach($text as $title)
{
	 
	//
	$img_name=strtolower(str_replace(" ","-",$title));
	$size_arr=array("width"=>"1366","height"=>"768"); //define height and width
	$savepath="images/".$img_name.".jpg";
	$watermark="w3school test watermark";
	$rgb=array("34","96","76");//define a light green rgb scheme
	$img_obj->generate_img($title,$savepath,$size_arr,$watermark,$rgb); //call the generate image function
	// 
 
	
}

//generate multiple images in loop

?>

<?php

include 'class.img.php';//include class file for generate image

//now create a instance of img class with font file names and sizes as following

$font_file1="fonts/arial.ttf";

$font_file2="fonts/times.ttf";

$text_to_image="THIS IS MY TEXT";//

$size_arr=array("width"=>"1366","height"=>"768"); //define height and width

$savepath="images/".$img_name.".jpg";

$watermark="w3school test watermark";

$rgb=array("34","96","76");//define a light green rgb scheme

$img_obj->generate_img($title,$savepath,$size_arr,$watermark,$rgb); //call the generate image function

}

//generate multiple images in loop
