이 기사의 예에서는 PHP에 업로드된 파일에서 썸네일을 만드는 방법을 설명합니다. 참고할 수 있도록 모든 사람과 공유하세요. 구체적인 구현 방법은 다음과 같습니다.
<?php if ($_REQUEST['action']=="add"){ $userfile = $HTTP_POST_FILES['photo']['tmp_name']; $userfile_name = $HTTP_POST_FILES['photo']['name']; $userfile_size = $HTTP_POST_FILES['photo']['size']; $userfile_type = $HTTP_POST_FILES['photo']['type']; ///////////////////////// //GET-DECLARE DIMENSIONS // $dimension = getimagesize($userfile); $large_width = $dimension[0]; // GET PHOTO WIDTH $large_height = $dimension[1]; //GET PHOTO HEIGHT $small_width = 120; // DECLARE THUMB WIDTH $small_height = 90; // DECLARE THUMB HEIGHT ///////////////////////// //CHECK SIZE // if ($userfile_size>102400){ $error=1; $msg = "The photo is over 100kb. Please try again."; } //////////////////////////////// // CHECK TYPE (IE AND OTHERS) // if ($userfile_type="image/pjpeg"){ if ($userfile_type!="image/jpeg"){ $error=1; $msg = "The photo must be JPG"; } } ////////////////////////////// //CHECK WIDTH/HEIGHT // if ($large_width!=600 or$large_height!=400){ $error=1; $msg = "The photo must be 600x400 pixels"; } /////////////////////////////////////////// //CREATE THUMB / UPLOAD THUMB AND PHOTO /// if ($error<>1){ $image = $userfile_name; //if you want to insert it to the database $pic = imagecreatefromjpeg($userfile); $small = imagecreatetruecolor($small_width,$small_height); imagecopyresampled($small,$pic,0,0,0,0, $small_width, $small_height, $large_width, $large_height); if (imagejpeg($small,"path/to/folder/to/upload/thumb".$userfile_name, 100)){ $large = imagecreatetruecolor($large_width,$large_height); imagecopyresampled($large,$pic,0,0,0,0, $large_width, $large_height, $large_width, $large_height); if (imagejpeg($large,"path/to/folder/to/upload/photo".$userfile_name, 100)) {} else {$msg="A problem has occured.
