php實現圖片上傳並利用ImageMagick產生縮圖

使用ImageMagick，您可以輕鬆，更快地建立縮圖，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{?><?phpforeach(glob($smalDir.'*') as $img){echo '  ';}}?>
