How to rotate image in php?

Question

I have a function that generates text that matches the bottom of the circle. Since I don’t know another way that I can make the function fit the top of the circle so that it appears in front of me, I want to rotate the image, write on it, rotate it back and write it again. How can I do this without changing the image name?

I tried something like this:

<?php function create_image() { $im = @imagecreate(140, 140)or die("Cannot Initialize new GD image stream"); $background_color = imagecolorallocate($im, 255, 255, 255); imageellipse ( $im , $cx , $cy , $size*2 , $size*2 , $black ); write($im,$cx,$cy,$size,$s,$e,$black,$text1,$font,$size,$pad); imagerotate($im, 180,0); write($im,$cx,$cy,$size,$s,$e,$black,$text2,$font,$size,$pad); imagerotate($im, 180,0); imagepng($im,"image.png"); imagedestroy($im); } ?> <?php create_image(); print "<img src=image.png?".date("U").">"; ?> 

But that will not work. He does not rotate the image.

Can you help me?

Thanx!

Not sure why you need to rotate twice .. but this is what your code should look like

 function create_image($img) { $im = @imagecreatefrompng($img) or die("Cannot Initialize new GD image stream"); $rotate = imagerotate($im, 180, 0); imagepng($rotate); imagedestroy($rotate); imagedestroy($im); } header('Content-Type: image/png'); $image = "a.png"; create_image($image);

Why don't you just take a normal image and add CSS to it?

CSS

 .yourImage { -webkit-transform: rotate(-90deg); -moz-transform: rotate(-90deg); filter: progid:DXImageTransform.Microsoft.BasicImage(rotation=3); } 

HTML

 <img class="yourImage" src="originalImage.jpg">

You can do this easily using the php rotation function. Here is a simple code

 <?php $image = 'test.jpg'; // The file you are rotating //How many degrees you wish to rotate $degrees = 180; // This sets the image type to .jpg but can be changed to png or gif header('Content-type: image/jpeg') ; // Create the canvas $src = $image; $system = explode(".", $src); if (preg_match("/jpg|jpeg/", $system[1])) { $src_img=imagecreatefromjpeg($src); } if (preg_match("/png/", $system[1])) { $src_img = imagecreatefrompng($src); } if (preg_match("/gif/", $system[1])) { $src_img = imagecreatefromgif($src); } // Rotates the image $rotate = imagerotate($src_img, $degrees, 0) ; // Outputs a jpg image, you could change this to gif or png if needed if (preg_match("/png/", $system[1])) { imagepng($rotate,$image); } else if (preg_match("/gif/", $system[1])) { imagegif($rotate, $image); } else { imagejpeg($rotate, $image); } imagedestroy($rotate); imagedestroy($src_img); ?>
