Get variable used to create image - php

I'm making my own 'captcha' form and I now have a page that generates the image:
<?php
header('Content-Type: image/png');
$im = imagecreatetruecolor(200, 50);
$white = imagecolorallocate($im, 255, 255, 255);
$gray = imagecolorallocate($im, 160, 160, 160);
imagefilledrectangle($im, 0, 0, 200, 50, $white);
$captcha = "SOMErandomTEXT";
$font = 'Chewy.ttf';
imagettftext($im, 20, 0, 0, 20, $gray, $font, $captcha);
imagepng($im);
imagedestroy($im);
?>
Now I also have another page that shows this image, inside the form. Now I want to get the value $captcha from the page shown above on the other page. How can I do it?

Using sessions did the job for me.

Can't save image that created with php - imagepng();

Hi I coded an image generator from textbox to image, after it creates, when I want to save it as image it shows me
-*.php file, and not .png (image)-
code:
$name = $_POST['tekst'];
$file ="imgs/tbybc1.png";
header('Content-Type: image/png');
$im = imagecreatefrompng($file);
$white = imagecolorallocate($im, 255, 255, 255);
$grey = imagecolorallocate($im, 128, 128, 128);
$black = imagecolorallocate($im, 0, 0, 0);
$text = $name;
$font = 'fonts/Roboto-Thin.ttf';
imagettftext($im, 40, 0, 70, 215, $white, $font, $text);
//imagettftext($im, 20, 0, 260, 255, $white, $font, $data);
imagepng($im);
imagedestroy($im);
what can I do for it, i googled but I didn't find anything. is there any solution to do this? or if there is any method of image generator tell me :) Thank You :)
You can use a htaccess rewrite for this.
eg.
RewriteRule ^/captcha.png$ /gen.php [NC,L]
then just include captcha.png in your page source:
<img src="/captcha.png" alt="" />

php how add transparent background color for php image?

background is comming in white i want to remove white and put transparent.please help
this is an image: http://funbusy.com/fbtest/user_image.php
?php
// Create the image
$im = imagecreatetruecolor(400, 25);
// Create some colors
$white = imagecolorallocate($im, 255, 255, 255);
$grey = imagecolorallocate($im, 128, 128, 128);
$black = imagecolorallocate($im, 22, 125, 0);
imagefilledrectangle($im, 0, 0, 399, 29, $white);
// The text to draw
$text = ucwords('tanuja sree');
// Replace path by your own font path
$font = 'OpenSans-Italic.ttf';
// Add some shadow to the text
imagettftext($im, 20, 0, 11, 21, $grey, $font, $text);
// Add the text
imagettftext($im, 20, 0, 10, 20, $black, $font, $text);
// Using imagepng() results in clearer text compared with imagejpeg()
ob_start();
imagepng($im);
$image_data = ob_get_clean();
$image_code = '<img id="image_code" src="data:image/png;base64,'. base64_encode($image_data) . '">';

Try adding this piece of code after imagettftext($im, 20, 0, 10, 20, $black, $font, $text);
imagecolortransparent($im, $white);
imagesavealpha($im,true);
imagealphablending($im, true);

Weird image glitch when using imagepng()

I am trying to make a gamecard for a RSPS. This is my first time using PHP to generate text on images and when trying to apply this weird glitch happens:
But, when the original photo looks like this:
As you can see the corners are not curved like they should be. But, in the original it comes out fine. I am not talking about the location of the numbers.
Here is the code I am using:
<?php
header('Content-Type: image/png');
// Image Creation
$image_file = "SoulSplitCard.png";
$im = imagecreatefrompng($image_file);
//Colors
$white = imagecolorallocate($im, 255, 255, 255);
$grey = imagecolorallocate($im, 128, 128, 128);
$black = imagecolorallocate($im, 0, 0, 0);
$rscol = imagecolorallocate($im, 23, 113, 183);
// Levels (for now)
$text = '99';
$text2 = '87';
// Font
$font = 'arial.ttf';
//Text Applications
imagettftext($im, 15, 0, 150, 35, $rscol, $font, $text);
imagettftext($im, 15, 0, 150, 81, $rscol, $font, $text2);
// Using imagepng() instead of imagejpeg()
imagepng($im);
imagedestroy($im);
?>
What is causing this to happen?

Making captcha image in PHP

I'm trying to use the GD graphics library to make this captcha image, and the box shows up how Id like it to, but the text isn't being displayed over the image at all. I can't figure out why it's not showing up.
<?php
session_start();
putenv('GDFONTPATH=' . realpath('.') );
$font = 'Molle';
header('Content-Type: image/png');
$im = imagecreatetruecolor(260, 40);
$white = imagecolorallocate($im, 255, 255,255);
$grey = imagecolorallocate($im, 215, 215, 215);
$black = imagecolorallocate($im, 0, 0, 0);
imagefilledrectangle($im, 3, 3, 255, 34, $grey);
$text = 'Testing';
$_SESSION["captcha"] = $text;
imagettftext( $im, 20, 0, 16, 26, $white, $font, $text );
imagettftext( $im, 20, 0, 15, 25, $black, $font, $text );
imagepng($im);
imagedestroy($im);
?>

How to add a background image while creating a text image using php?

I'm currently using the following script--
<?php
// Set the content-type
header('Content-type: image/png');
// Create the image
$im = imagecreatetruecolor(400, 30);
// Create some colors
$white = imagecolorallocate($im, 255, 255, 255);
$grey = imagecolorallocate($im, 128, 128, 128);
$black = imagecolorallocate($im, 115, 150, 195);
imagefilledrectangle($im, 0, 0, 399, 29, $white);
// The text to draw
$text = 'My Name';
// Replace path by your own font path
$font = 'AGENCYB.TTF';
// Add some shadow to the text
imagettftext($im, 20, 0, 11, 21, $grey, $font, $text);
// Add the text
imagettftext($im, 20, 0, 10, 20, $black, $font, $text);
// Using imagepng() results in clearer text compared with imagejpeg()
imagepng($im);
imagedestroy($im);
?>
But I want to add a background image too. Please help, I'm new to this function especially.
Would something like the following work for you? You want to open the image you want to use as the background, and then write your text over the top.
<?php
// Set the content-type
header('Content-type: image/png');
/* Attempt to open */
$im = #imagecreatefrompng('backgroundimage.png');
/* See if it failed */
if(!$im)
{
// Create some colors
$white = imagecolorallocate($im, 255, 255, 255);
$grey = imagecolorallocate($im, 128, 128, 128);
$black = imagecolorallocate($im, 115, 150, 195);
imagefilledrectangle($im, 0, 0, 399, 29, $white);
// The text to draw
$text = 'My Name';
// Replace path by your own font path
$font = 'AGENCYB.TTF';
// Add some shadow to the text
imagettftext($im, 20, 0, 11, 21, $grey, $font, $text);
// Add the text
imagettftext($im, 20, 0, 10, 20, $black, $font, $text);
// Using imagepng() results in clearer text compared with imagejpeg()
imagepng($im);
imagedestroy($im);
}else
{
//you want to do something here if your image didn't open like maybe fpassthru an alternative image
}
?>
