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 $_SERVER["PHP_SELF"]; ?> " method="post" enctype="multipart/form-data"><p><input type="file" name="photo" /></p><p><input type="submit" value="Upload!" name="submit" /></p></form><?phpforeach(glob($smalDir."*") as $img){echo " <img src="".str_replace($_SERVER["DOCUMENT_ROOT"], "",$img)."" /> ";}}?>希望本文所述对大家学习php程序设计有所帮助。
