how to rotate image in php?

image, php, rotation

Solution

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);

Problem

I have a function that generates text that fits the lower part of a circle. Because I do not know any other way that I can make the function fit the upper part of the circle so that it faces me, I want to rotate the image, write on it, rotate it back and again write on it. How can I do that without changing the name of the image? I have 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 it doesn't work. It doesn't rotate the image. Can you please help me? Thanx !
