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。
<?php // 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{ ?> <form action=" <?php echo $_SERVER['PHP_SELF']; ?> " method="post" enctype="multipart/form-data"> <p><input type="file" /></p> <p><input type="submit" value="Upload!" /></p> </form> <?php foreach(glob($smalDir.'*') as $img){ echo ' <img src="'https://www.jb51.net/article/.str_replace($_SERVER['DOCUMENT_ROOT'], '',$img).'" /> '; } } ?>
