Through the replacement technology of string, the specified characters in the specified string can be replaced. String replacement technology can be implemented through the following two functions: str_irplace() function and substr_replace() function.
str_irplace() function
Use a new string (substring) to replace the specified string to be replaced in the original string .
The syntax format is as follows:
str_irplace(search, replace, subject, count)
Copy after login
Instructions: Replace all the parameter subject that appears in the parameter subject with the parameter replace, and the parameter count represents the number of times the replacement string is executed. The str_irplace() function is not case sensitive.
##parameter number
say 明
search
Required parameters, specify the string to be found
#replace
Required parameters, specify the value to be replaced
subject
Required parameters, specify the range to be searched
count
Optional parameters, get the number of times to perform replacement
Replace the string specified in the text, and then output the replaced result. The example code is as follows:
Watching ** play a game is like having unrequited love for someone who doesn't love you. If he gives you a little bit of a good look, you think it's okay.
Note: This function is not case-sensitive when performing the replacement operation. If you need to distinguish between upper and lower case, you can use the str_replace() function. The most commonly used string replacement technology is in the keyword processing of
Note: Marking the query keywords in red means marking the query keywords in a special color, font size or font. This allows the viewer to quickly find the required keywords and facilitates the viewer to select from the search results. Find what you need. Query keywords marked in red are suitable for fuzzy queries. The following uses a specific example to introduce how to implement the red marking function of query keywords. Use the str_irplace() function to replace the query keyword. When the relevant information being queried is displayed, replace the font of the output keyword with red. The sample code is as follows:
WatchNational Football TeamPlaying a game is like having unrequited love for someone who doesn’t love you. If he gives you a little bit of a good look, you I thought it was going to work
Note: The query keyword red function is widely used in search engines. I hope that friends can learn from examples and draw inferences to develop more flexible and convenient programs.
substr_replace() function
Replaces part of the string in the specified string. The syntax format is as follows:

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
A string is a sequence of characters, including letters, numbers, and symbols. This tutorial will learn how to calculate the number of vowels in a given string in PHP using different methods. The vowels in English are a, e, i, o, u, and they can be uppercase or lowercase.
What is a vowel?
Vowels are alphabetic characters that represent a specific pronunciation. There are five vowels in English, including uppercase and lowercase:
a, e, i, o, u
Example 1
Input: String = "Tutorialspoint"
Output: 6
explain
The vowels in the string "Tutorialspoint" are u, o, i, a, o, i. There are 6 yuan in total
What are the magic methods of PHP? PHP's magic methods include: 1.\_\_construct, used to initialize objects; 2.\_\_destruct, used to clean up resources; 3.\_\_call, handle non-existent method calls; 4.\_\_get, implement dynamic attribute access; 5.\_\_set, implement dynamic attribute settings. These methods are automatically called in certain situations, improving code flexibility and efficiency.
PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.
PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.
PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7
PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.
