Yii Framework中插入时间类型数据到数据库
在PHP代码中取得当前日期时间再插入数据库 默认情况下,PHP解释显示的时间为“林威治标准时间”,与我们本地的时间相差8个小时 ,所以date(“Y-m-d H:i:s”)得出的时间比当前时间少了8个小时。 gmdate(“Y-m-d H:i:s”)函数得出的时间是经过与GMT相加减过的,
在PHP代码中取得当前日期时间再插入数据库
默认情况下,PHP解释显示的时间为“格林威治标准时间”,与我们本地的时间相差8个小时
,所以date(“Y-m-d H:i:s”)得出的时间比当前时间少了8个小时。
gmdate(“Y-m-d H:i:s”)函数得出的时间是经过与GMT相加减过的,能得到本地时间,但要在
PHP.ini中用date.timezone这个选项设置时区,但默认是关闭的,而且在部分PHP版本中无法
正常实现。
一个比较好的实现的方法,手动修正时差,如下:
$timeoffset = 8; echo gmdate("Y-m-d H:i:s", mktime() + $timeoffset * 3600) . "<br>"; echo gmdate("Y-m-d H:i:s", time() + $timeoffset * 3600) . "<br>"; echo date("Y-m-d H:i:s", mktime() + $timeoffset * 3600) . "<br>"; echo date("Y-m-d H:i:s", time() + $timeoffset * 3600) . "<br>";
都输出如下格式:2007-11-24 17:41:58
根据上述的知识,很快,我顺利插入了数据,代码如下:
public function actionAdd() { $news_model = new News(); $news_model->title = "测试的第6条新闻标题"; $news_model->pubdate = date("Y-m-d H:i:s", time() + 8 * 3600); $news_model->author = "yuanpengfei"; if ($news_model->save()) { echo "success save"; } else { echo "failed save"; } }

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

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,

Last week, amid the internal wave of resignations and external criticism, OpenAI was plagued by internal and external troubles: - The infringement of the widow sister sparked global heated discussions - Employees signing "overlord clauses" were exposed one after another - Netizens listed Ultraman's "seven deadly sins" Rumors refuting: According to leaked information and documents obtained by Vox, OpenAI’s senior leadership, including Altman, was well aware of these equity recovery provisions and signed off on them. In addition, there is a serious and urgent issue facing OpenAI - AI safety. The recent departures of five security-related employees, including two of its most prominent employees, and the dissolution of the "Super Alignment" team have once again put OpenAI's security issues in the spotlight. Fortune magazine reported that OpenA

Apple's latest releases of iOS18, iPadOS18 and macOS Sequoia systems have added an important feature to the Photos application, designed to help users easily recover photos and videos lost or damaged due to various reasons. The new feature introduces an album called "Recovered" in the Tools section of the Photos app that will automatically appear when a user has pictures or videos on their device that are not part of their photo library. The emergence of the "Recovered" album provides a solution for photos and videos lost due to database corruption, the camera application not saving to the photo library correctly, or a third-party application managing the photo library. Users only need a few simple steps

How to use MySQLi to establish a database connection in PHP: Include MySQLi extension (require_once) Create connection function (functionconnect_to_db) Call connection function ($conn=connect_to_db()) Execute query ($result=$conn->query()) Close connection ( $conn->close())

To handle database connection errors in PHP, you can use the following steps: Use mysqli_connect_errno() to obtain the error code. Use mysqli_connect_error() to get the error message. By capturing and logging these error messages, database connection issues can be easily identified and resolved, ensuring the smooth running of your application.

Llama3, the majestic king of open source, the original context window is only... 8k, which makes me swallow back the words "it smells so good". Today, when 32k is the starting point and 100k is common, is this intentional to leave room for contributions to the open source community? The open source community certainly didn't miss this opportunity: now with just 58 lines of code, any fine-tuned version of Llama370b can automatically scale to 1048k (one million) contexts. Behind the scenes is a LoRA, extracted from a fine-tuned version of Llama370BInstruct that extends good context, and the file is only 800mb. Next, using Mergekit, you can run it with other models of the same architecture or merge it directly into the model. 1048k context used

70B model, 1000 tokens can be generated in seconds, which translates into nearly 4000 characters! The researchers fine-tuned Llama3 and introduced an acceleration algorithm. Compared with the native version, the speed is 13 times faster! Not only is it fast, its performance on code rewriting tasks even surpasses GPT-4o. This achievement comes from anysphere, the team behind the popular AI programming artifact Cursor, and OpenAI also participated in the investment. You must know that on Groq, a well-known fast inference acceleration framework, the inference speed of 70BLlama3 is only more than 300 tokens per second. With the speed of Cursor, it can be said that it achieves near-instant complete code file editing. Some people call it a good guy, if you put Curs
