该文件的权限未设置为写模式。它设置为777，并具有以下code测试。
The file permissions was not set to writing mode. set it to 777 and tested with the following code.
<?php
$base = $_POST['encoded'];
$base = base64_decode($base);
$im = imagecreatefromstring($base);
if ($im !== false) {
header('Content-Type: image/png');
imagepng($im,'image.png'); // saving image to the same directory
imagedestroy($im);
}
else {
echo 'An error occurred.';
}
?>
