The method to get the current time without date in PHP is to use the date() function and specify the format. The specific steps are as follows: 1. Use echo date("H:i:s") to get the current time (including seconds) of the 24-hour system; 2. Use echo date("H:i") to get the current time (excluding seconds) of the 24-hour system; 3. Use echo date("h:i A") to get the current time (including AM/PM) of the 12-hour system; 4. Use date_default_timezone_set() to set the time zone to ensure the accuracy of time, such as date_default_timezone_set("Asia/Shanghai"); 5. Note that the time() function only returns a timestamp and needs to be used in combination with date().
To get the current time (without date) in PHP is actually quite simple, the key is to format the time output. PHP provides a date() function, which can easily extract the current hours, minutes and seconds.
Use the date() function to get the current time
This is the most commonly used method. date() function allows you to control the output time format by specifying the format string. If you want to display only the time part, you can use the following format:
echo date("H:i:s"); This code will output a result similar to 14:35:22 , indicating the current hours (24-hour system), minutes and seconds.
If you don't need seconds, only hours and minutes, you can write this:
echo date("H:i"); This outputs a time like 14:35 .
Get time in different formats (such as 12-hour time)
Sometimes you may want to use AM/PM format to display time. At this time you can use the following format:
echo date("h:i A"); This outputs a time similar to 02:35 PM , suitable for scenarios that require a more friendly display.
Notice:
-
hmeans 12-hour hours -
Ameans uppercase AM or PM
Set the time zone (avoid inaccurate time)
By default, date() uses the time zone where the server is located. But many times you may want to display the time according to your needs, such as Beijing time or Eastern Time.
At this time, you need to set the time zone first, for example:
date_default_timezone_set("Asia/Shanghai");
echo date("H:i:s");This ensures that the output is the current time in your time zone.
Common time zones include:
-
America/New_York -
Europe/London -
Asia/Tokyo
You can choose the right time zone according to your actual needs.
Small details: the difference between time() and date()
Sometimes you will see time() function, which returns the current Unix timestamp (seconds starting January 1, 1970) and cannot be used directly to display "current time". So if you want to display a good readability time, you still have to use date() .
Basically that's it. By mastering these tips, you can flexibly deal with the problem of obtaining the current time in PHP.

How can you handle file uploads securely in PHP?
Jun 19, 2025 am 01:05 AM
To safely handle file uploads in PHP, the core is to verify file types, rename files, and restrict permissions. 1. Use finfo_file() to check the real MIME type, and only specific types such as image/jpeg are allowed; 2. Use uniqid() to generate random file names and store them in non-Web root directory; 3. Limit file size through php.ini and HTML forms, and set directory permissions to 0755; 4. Use ClamAV to scan malware to enhance security. These steps effectively prevent security vulnerabilities and ensure that the file upload process is safe and reliable.
What are the differences between == (loose comparison) and === (strict comparison) in PHP?
Jun 19, 2025 am 01:07 AM
In PHP, the main difference between == and == is the strictness of type checking. ==Type conversion will be performed before comparison, for example, 5=="5" returns true, and ===Request that the value and type are the same before true will be returned, for example, 5==="5" returns false. In usage scenarios, === is more secure and should be used first, and == is only used when type conversion is required.
How can you interact with NoSQL databases (e.g., MongoDB, Redis) from PHP?
Jun 19, 2025 am 01:07 AM
Yes, PHP can interact with NoSQL databases like MongoDB and Redis through specific extensions or libraries. First, use the MongoDBPHP driver (installed through PECL or Composer) to create client instances and operate databases and collections, supporting insertion, query, aggregation and other operations; second, use the Predis library or phpredis extension to connect to Redis, perform key-value settings and acquisitions, and recommend phpredis for high-performance scenarios, while Predis is convenient for rapid deployment; both are suitable for production environments and are well-documented.
How do I perform arithmetic operations in PHP ( , -, *, /, %)?
Jun 19, 2025 pm 05:13 PM
The methods of using basic mathematical operations in PHP are as follows: 1. Addition signs support integers and floating-point numbers, and can also be used for variables. String numbers will be automatically converted but not recommended to dependencies; 2. Subtraction signs use - signs, variables are the same, and type conversion is also applicable; 3. Multiplication signs use * signs, which are suitable for numbers and similar strings; 4. Division uses / signs, which need to avoid dividing by zero, and note that the result may be floating-point numbers; 5. Taking the modulus signs can be used to judge odd and even numbers, and when processing negative numbers, the remainder signs are consistent with the dividend. The key to using these operators correctly is to ensure that the data types are clear and the boundary situation is handled well.
