我的 PHP 脚本无法上传 50M 以上的图片

Question

我必须上传 75MB（JPEG 和 PNG）的图像。出现这样的错误：

（致命错误：内存不足（已分配-1912078336）（试图分配30000字节）

如果我上传 40+、50+ 以上的 png 或 jpeg。

在这一步$new_image = imagecreatetruecolor($width, $height); 如果我上传 30+ JPG 图片我会收到错误：

致命错误：内存不足（已分配-1910767616）（试图分配43200字节）

我还在 PHP 值下方的 .htaccess 中添加：

php_value upload_max_filesize 2000M
php_value max_input_time 1000
php_value memory_limit 2000M
php_value max_execution_time 20000
php_value post_max_size 2000M

这是脚本：

<?php
set_time_limit(300);
ini_set('memory_limit', '64800M');
ini_set("max_execution_time",10000);
ini_set ("display_errors", "1");
error_reporting(E_ALL);

$target_dir = "uploads/";
$unq_name=(mt_rand(10,1000));
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);

$source_photo = 'uploads/'.basename( $_FILES["fileToUpload"]["name"]);
$dest_photo = 'uploads/testing_'.$unq_name.'.'.$imageFileType;


$image = new SimpleImage(); 
$image->load($source_photo);
$image->scale(50);
$image->save($dest_photo);

请更改您的 php.ini 设置。

找线：

upload_max_filesize = 100M
post_max_size = 100M
