你可以很容易地使用css。
.rounded-image {
border-radius: 160px;
overflow: hidden;
}

<img src="http://i.stack.imgur.com/mhjeT.jpg" class="rounded-image" />

<?php
// Created by NerdsOfTech
// Step 1 - Start with image as layer 1 (canvas).
$img1 = ImageCreateFromjpeg("img.jpg");
$x=imagesx($img1)-$width ;
$y=imagesy($img1)-$height;
// Step 2 - Create a blank image.
$img2 = imagecreatetruecolor($x, $y);
$bg = imagecolorallocate($img2, 255, 255, 255); // white background
imagefill($img2, 0, 0, $bg);
// Step 3 - Create the ellipse OR circle mask.
$e = imagecolorallocate($img2, 0, 0, 0); // black mask color
// Draw a ellipse mask
// imagefilledellipse ($img2, ($x/2), ($y/2), $x, $y, $e);
// OR
// Draw a circle mask
$r = $x <= $y ? $x : $y; // use smallest side as radius & center shape
imagefilledellipse ($img2, ($x/2), ($y/2), $r, $r, $e);
// Step 4 - Make shape color transparent
imagecolortransparent($img2, $e);
// Step 5 - Merge the mask into canvas with 100 percent opacity
imagecopymerge($img1, $img2, 0, 0, 0, 0, $x, $y, 100);
// Step 6 - Make outside border color around circle transparent
imagecolortransparent($img1, $bg);
// Step 7 - Output merged image
header("Content-type: image/png"); // output header
$input = imagepng($img1); // output merged image
$output = 'vola.png';
file_put_contents($output, file_get_contents($input));
// Step 8 - Cleanup memory
imagedestroy($img2); // kill mask first
imagedestroy($img1); // kill canvas last

先生,我得到了这段代码。只是无法将其保存到我的文件夹中。
感谢。
