【问题描述】：
我使用PHP Image Magician 为图像创建缩略图和多重上传表单。当我尝试上传 10 张大小约为 30kb 的图像时，它们会被上传，但如果我尝试上传 2 张大小约为 6-7mb 的图像，它只会将第一张图像保存到文件夹和数据库中，然后页面就会崩溃。没有将任何内容保存到拇指文件夹中。
如果我尝试只使用一张图像，它将保存到两个文件夹（普通 + 拇指）和数据库中。完全没有问题。
我也在php.ini中增加了
max_execution_time: 600;
max_input_time: 600;
memory_limit: 96;
upload_max_filesize: 100;
post_max_size: 100;
可能是什么问题。如果需要，我还可以发布一些来源。
编辑：upload.php
if (isset($_POST["sub2"])) {
// include resized library
require_once('php-image-magician/php_image_magician.php');
$msg = "";
$valid_image_check = array("image/gif", "image/jpeg", "image/jpg", "image/png", "image/bmp");
if (count($_FILES["user_files"]) > 0) {
$folderName = "../../images/gallery/";
$thumbFolder = "../../gallery/thumb/";
$sql = "INSERT INTO images (image_name, image_size, image_type, image_album, image_path, image_thumb) VALUES (:img, :size, :type, :album, :path, :thumb)";
$stmt = $pdo->prepare($sql);
for ($i = 0; $i < count($_FILES["user_files"]["name"]); $i++) {
if ($_FILES["user_files"]["name"][$i] <> "") {
$image_mime = strtolower(image_type_to_mime_type(exif_imagetype($_FILES["user_files"]["tmp_name"][$i])));
// if valid image type then upload
if (in_array($image_mime, $valid_image_check)) {
$ext = explode("/", strtolower($image_mime));
$ext = strtolower(end($ext));
$filename = rand(10000, 990000) . '_' . time() . '.' . $ext;
$filepath = $folderName . $filename;
$thumbpath = $thumbFolder . $filename;
$fileSize = $_FILES['user_files']['size'][$i];
$fileType = $_FILES['user_files']['type'][$i];
$album = $_POST['image_album'];
if (!move_uploaded_file($_FILES["user_files"]["tmp_name"][$i], $filepath)) {
$emsg .= "Error while uploading - <strong>" . $_FILES["user_files"]["name"][$i] . "</strong>. Please, try again. <br>";
$counter++;
} else {
$smsg .= "Image <strong>" . $_FILES["user_files"]["name"][$i] . "</strong> is added successfully . <br>";
/* * ****** insert into database starts ******** */
$magicianObj = new imageLib($filepath);
$magicianObj->resizeImage(500, 500);
$magicianObj->saveImage($folderName . 'thumb/' . $filename, 500);
try {
$stmt->bindValue(":img", $filename);
$stmt->bindValue(":size", $fileSize);
$stmt->bindValue(":type", $fileType);
$stmt->bindValue(":album", $album);
$stmt->bindValue(":path", $filepath);
$stmt->bindValue(":thumb", $thumbpath);
$stmt->execute();
$result = $stmt->rowCount();
if ($result > 0) {
// file uplaoded successfully.
} else {
// failed to insert into database.
}
} catch (Exception $ex) {
$emsg .= "<strong>" . $ex->getMessage() . "</strong>. <br>";
}
/* * ****** insert into database ends ******** */
}
} else {
$emsg .= "This file <strong>" . $_FILES["user_files"]["name"][$i] . "</strong> is not an image. <br>";
}
}
}
$msg .= (strlen($smsg) > 0) ? successMessage($smsg) : "";
$msg .= (strlen($emsg) > 0) ? errorMessage($emsg) : "";
} else {
$msg = errorMessage("You need to add at least one image.");
}
}
和表格
<form name="f2" action="" method="post" enctype="multipart/form-data">
<fieldset>
<select name="image_album">
<option></option>;
</select><br/><br />
<input class="files" name="user_files[]" type="file" multiple><span><a href="javascript:void(0);" class="add" >add more</a></span>
<div><input type="submit" class="submit" name="sub2" value="Up" /> </div>
</fieldset>
</form>
编辑
<?php
function errorMessage($smsg) {
return '<div style="width:50%; margin:0 auto; border:2px solid #F00;padding:2px; color:#000; margin-top:10px; text-align:center;">' . $smsg . '</div>';
}
function successMessage($str) {
return '<div style="width:50%; margin:0 auto; border:2px solid #06C;padding:2px; color:#000; margin-top:10px; text-align:center;">' . $str . '</div>';
}
?>
