post 数据大小的限制问题
遇到一个问题:往后台post提交数据时,当超过一定大小,就发现后台的post数据为空,后台收不到post数据。
请问是什么原因?是不是因为屏蔽了哪个php函数?还是php.ini的某项设置?
php.ini 中 post_max_size = 64M;
回复讨论(解决方案)
php 5.3.9 以后还有个数据项数的限制
php 5.3.9 以后还有个数据项数的限制
请问是哪个数据项限制?
post 表单控件数

是 max_file_uploads 么?
你有上?文件的??
?有一?upload_max_filesize 需要?
你有上?文件的??
?有一?upload_max_filesize 需要?
upload_max_filesize = 30M
max_file_uploads = 500
post_max_size = 64M;
这个设置按道理是可以满足一般post数据提交。
是的,但你的??有多大呢?
你post的数据有多大,print_r($_POST); 看看。
你post的数据有多大,print_r($_POST); 看看。
echo print_r($_POST);
输出结果
Array
(
)
1
很奇怪的输出。
print_r($_POST);
print_r($_POST);
输出结果显示,没有提交的那个数据过大的post变量。
单独测试了一下,数据如果超过 64999,就无法正常提交,小于这个数据,后台能收到。
另外,这个数据过大,不影响别的post数据。
print_r($_POST);
打印出空数组,表示你没有用 post 方式提交
或是你在 php.ini 禁用了 post 提交方式
如果是 post 失败(数据超出允许范围)则打印出的是什么都没有
print_r($_POST);
打印出空数组,表示你没有用 post 方式提交
或是你在 php.ini 禁用了 post 提交方式
如果是 post 失败(数据超出允许范围)则打印出的是什么都没有
好像是被限制了单个post数据的大小,但是,不知道是在php.ini里面被限制的还是哪里,网上搜索的相关条件限制都无法解决这个问题。
你看看 echo file_get_contents('php://input'); 的结果
一般出错时都有错误信息,你也不去看看
查到原因了,前些天加了 suhosin 的功能,被这个 suhosin 给限制了。现在的问题变成:怎么配置 suhosin?
suhosin.post.max_value_length 65000 65000
搞定了,在php.ini里面添加 suhosin 的设置
suhosin.post.max_value_length = 4194304
suhosin.post.max_vars = 20000
suhosin.request.max_vars=2000

DDREASE is a tool for recovering data from file or block devices such as hard drives, SSDs, RAM disks, CDs, DVDs and USB storage devices. It copies data from one block device to another, leaving corrupted data blocks behind and moving only good data blocks. ddreasue is a powerful recovery tool that is fully automated as it does not require any interference during recovery operations. Additionally, thanks to the ddasue map file, it can be stopped and resumed at any time. Other key features of DDREASE are as follows: It does not overwrite recovered data but fills the gaps in case of iterative recovery. However, it can be truncated if the tool is instructed to do so explicitly. Recover data from multiple files or blocks to a single

0.What does this article do? We propose DepthFM: a versatile and fast state-of-the-art generative monocular depth estimation model. In addition to traditional depth estimation tasks, DepthFM also demonstrates state-of-the-art capabilities in downstream tasks such as depth inpainting. DepthFM is efficient and can synthesize depth maps within a few inference steps. Let’s read about this work together ~ 1.

The performance of JAX, promoted by Google, has surpassed that of Pytorch and TensorFlow in recent benchmark tests, ranking first in 7 indicators. And the test was not done on the TPU with the best JAX performance. Although among developers, Pytorch is still more popular than Tensorflow. But in the future, perhaps more large models will be trained and run based on the JAX platform. Models Recently, the Keras team benchmarked three backends (TensorFlow, JAX, PyTorch) with the native PyTorch implementation and Keras2 with TensorFlow. First, they select a set of mainstream

Facing lag, slow mobile data connection on iPhone? Typically, the strength of cellular internet on your phone depends on several factors such as region, cellular network type, roaming type, etc. There are some things you can do to get a faster, more reliable cellular Internet connection. Fix 1 – Force Restart iPhone Sometimes, force restarting your device just resets a lot of things, including the cellular connection. Step 1 – Just press the volume up key once and release. Next, press the Volume Down key and release it again. Step 2 – The next part of the process is to hold the button on the right side. Let the iPhone finish restarting. Enable cellular data and check network speed. Check again Fix 2 – Change data mode While 5G offers better network speeds, it works better when the signal is weaker

I cry to death. The world is madly building big models. The data on the Internet is not enough. It is not enough at all. The training model looks like "The Hunger Games", and AI researchers around the world are worrying about how to feed these data voracious eaters. This problem is particularly prominent in multi-modal tasks. At a time when nothing could be done, a start-up team from the Department of Renmin University of China used its own new model to become the first in China to make "model-generated data feed itself" a reality. Moreover, it is a two-pronged approach on the understanding side and the generation side. Both sides can generate high-quality, multi-modal new data and provide data feedback to the model itself. What is a model? Awaker 1.0, a large multi-modal model that just appeared on the Zhongguancun Forum. Who is the team? Sophon engine. Founded by Gao Yizhao, a doctoral student at Renmin University’s Hillhouse School of Artificial Intelligence.

The latest video of Tesla's robot Optimus is released, and it can already work in the factory. At normal speed, it sorts batteries (Tesla's 4680 batteries) like this: The official also released what it looks like at 20x speed - on a small "workstation", picking and picking and picking: This time it is released One of the highlights of the video is that Optimus completes this work in the factory, completely autonomously, without human intervention throughout the process. And from the perspective of Optimus, it can also pick up and place the crooked battery, focusing on automatic error correction: Regarding Optimus's hand, NVIDIA scientist Jim Fan gave a high evaluation: Optimus's hand is the world's five-fingered robot. One of the most dexterous. Its hands are not only tactile

This week, FigureAI, a robotics company invested by OpenAI, Microsoft, Bezos, and Nvidia, announced that it has received nearly $700 million in financing and plans to develop a humanoid robot that can walk independently within the next year. And Tesla’s Optimus Prime has repeatedly received good news. No one doubts that this year will be the year when humanoid robots explode. SanctuaryAI, a Canadian-based robotics company, recently released a new humanoid robot, Phoenix. Officials claim that it can complete many tasks autonomously at the same speed as humans. Pheonix, the world's first robot that can autonomously complete tasks at human speeds, can gently grab, move and elegantly place each object to its left and right sides. It can autonomously identify objects

Recently, the military circle has been overwhelmed by the news: US military fighter jets can now complete fully automatic air combat using AI. Yes, just recently, the US military’s AI fighter jet was made public for the first time and the mystery was unveiled. The full name of this fighter is the Variable Stability Simulator Test Aircraft (VISTA). It was personally flown by the Secretary of the US Air Force to simulate a one-on-one air battle. On May 2, U.S. Air Force Secretary Frank Kendall took off in an X-62AVISTA at Edwards Air Force Base. Note that during the one-hour flight, all flight actions were completed autonomously by AI! Kendall said - "For the past few decades, we have been thinking about the unlimited potential of autonomous air-to-air combat, but it has always seemed out of reach." However now,
