PHP Echo vs. PHP Short Echo Tags: A Comparison
In PHP, both the echo statement and the short echo tag (=) can be used to output data. However, there are some subtle differences between the two that should be considered.
Safety
Contrary to popular belief, the short echo tag is not less safe than the echo statement. It is actually a shorthand for
Performance
There is also no significant difference in performance between the two methods. Both the echo statement and the short echo tag are executed in the same way by the PHP interpreter.
Advantages and Disadvantages
The main advantage of the short echo tag is that it is more concise than the echo statement. This can be beneficial when writing large amounts of code, as it can save time and make the code more readable.
However, there are also some disadvantages to using the short echo tag. One disadvantage is that it is not supported in all versions of PHP. For example, it is not supported in PHP versions prior to 5.4.0. Another disadvantage is that it can be confusing to read for developers who are not familiar with PHP.
Conclusion
Ultimately, the decision of whether to use the echo statement or the short echo tag is a matter of personal preference. There is no significant difference in safety or performance between the two methods. However, it is important to consider the advantages and disadvantages of each method before making a decision.
Additional Notes
- The only true short open tag in PHP is the tag. It should be noted that the tag is not enabled by default, and it can be disabled using the short_open_tag directive in PHP's configuration file.
- For security reasons, it is always best practice to encode output data according to the rules of the output medium. For example, data that is echoed into HTML should be HTML-encoded, and data that is echoed into JavaScript should be JavaScript-encoded.

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.

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.

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.

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.
