图片上传并使用ImageMagick生成缩略图

使用ImageMagick，您可以轻松，更快地创建缩略图，比使用PHP的容易得多。

 // Location to upload main image:
$mainDir = $_SERVER['DOCUMENT_ROOT'].'/images/l/';
// Location to create the thumb image:
$smalDir = $_SERVER['DOCUMENT_ROOT'].'/images/s/';
// Command to use:
$command = '/usr/bin/convert';
// Thumbnail width:
$size = 210;
// Make sure we have an image:
if(isset($_POST['submit'])){
    if(getimagesize($_FILES['photo']['tmp_name'])){
        $name = $_FILES['photo']['name'];
        $uploadfile = $mainDir . $name;
        move_uploaded_file($_FILES['photo']['tmp_name'], $uploadfile);
        $lrgImg = $mainDir . $name;
        $smlImg = $smalDir . $name;
        $imageMagick = $command . " '". $lrgImg . "' -resize '$size' '" . $smlImg . "'";
        shell_exec($imageMagick);
    }
    header("Location: /test.php");
    exit;
}else{
?>


    foreach(glob($smalDir.'*') as $img){
        echo '  ';
    }
}
?>
