HomeBackend DevelopmentPHP Tutorial数组随机排序怎么随机排序

在1.2.3.4文本里面随机选择一行,然后组合成一句话,比如:
去干嘛,去吃饭,太好了,么么哒
或者
太好了,吃饱了,做什么,开心


回复讨论(解决方案)

$filenames=array('1.txt','2.txt','3.txt','4.txt');$str='';foreach($filenames as $k=>$file){	$tmp=file_get_contents($file);	$data[$k]=explode(PHP_EOL,$tmp);	$str.=$data[$k][array_rand($data[$k])].',';}echo $str;//太好了,吃饭了,去干嘛,谢谢,

$filenames=array('1.txt','2.txt','3.txt','4.txt');$str='';foreach($filenames as $k=>$file){	$tmp=file_get_contents($file);	$data[$k]=explode(PHP_EOL,$tmp);	$str.=$data[$k][array_rand($data[$k])].',';}echo $str;//太好了,吃饭了,去干嘛,谢谢,


测试了,你这个排序是顺序的,比如说从1.txt读取一行,接着2.txt读取一行,接着3.txt读取一行,4.txt读取一行组成的一句话。
我想要的效果是随机从1.2.3.4文本读取一行组成一句话。

在 $filenames=array('1.txt','2.txt','3.txt','4.txt'); 下面加上这一句
shuffle($filenames);

在 $filenames=array('1.txt','2.txt','3.txt','4.txt'); 下面加上这一句
shuffle($filenames);

非常感谢哦,我是个纯新手,稍微懂一点,但是不知道php的写法和顺序,反正特别累

When would you use a trait versus an abstract class or interface in PHP?When would you use a trait versus an abstract class or interface in PHP?Apr 10, 2025 am 09:39 AM

In PHP, trait is suitable for situations where method reuse is required but not suitable for inheritance. 1) Trait allows multiplexing methods in classes to avoid multiple inheritance complexity. 2) When using trait, you need to pay attention to method conflicts, which can be resolved through the alternative and as keywords. 3) Overuse of trait should be avoided and its single responsibility should be maintained to optimize performance and improve code maintainability.

What is a Dependency Injection Container (DIC) and why use one in PHP?What is a Dependency Injection Container (DIC) and why use one in PHP?Apr 10, 2025 am 09:38 AM

Dependency Injection Container (DIC) is a tool that manages and provides object dependencies for use in PHP projects. The main benefits of DIC include: 1. Decoupling, making components independent, and the code is easy to maintain and test; 2. Flexibility, easy to replace or modify dependencies; 3. Testability, convenient for injecting mock objects for unit testing.

Explain the SPL SplFixedArray and its performance characteristics compared to regular PHP arrays.Explain the SPL SplFixedArray and its performance characteristics compared to regular PHP arrays.Apr 10, 2025 am 09:37 AM

SplFixedArray is a fixed-size array in PHP, suitable for scenarios where high performance and low memory usage are required. 1) It needs to specify the size when creating to avoid the overhead caused by dynamic adjustment. 2) Based on C language array, directly operates memory and fast access speed. 3) Suitable for large-scale data processing and memory-sensitive environments, but it needs to be used with caution because its size is fixed.

How does PHP handle file uploads securely?How does PHP handle file uploads securely?Apr 10, 2025 am 09:37 AM

PHP handles file uploads through the $\_FILES variable. The methods to ensure security include: 1. Check upload errors, 2. Verify file type and size, 3. Prevent file overwriting, 4. Move files to a permanent storage location.

What is the Null Coalescing Operator (??) and Null Coalescing Assignment Operator (??=)?What is the Null Coalescing Operator (??) and Null Coalescing Assignment Operator (??=)?Apr 10, 2025 am 09:33 AM

In JavaScript, you can use NullCoalescingOperator(??) and NullCoalescingAssignmentOperator(??=). 1.??Returns the first non-null or non-undefined operand. 2.??= Assign the variable to the value of the right operand, but only if the variable is null or undefined. These operators simplify code logic, improve readability and performance.

What is Content Security Policy (CSP) header and why is it important?What is Content Security Policy (CSP) header and why is it important?Apr 09, 2025 am 12:10 AM

CSP is important because it can prevent XSS attacks and limit resource loading, improving website security. 1.CSP is part of HTTP response headers, limiting malicious behavior through strict policies. 2. The basic usage is to only allow loading resources from the same origin. 3. Advanced usage can set more fine-grained strategies, such as allowing specific domain names to load scripts and styles. 4. Use Content-Security-Policy-Report-Only header to debug and optimize CSP policies.

What are HTTP request methods (GET, POST, PUT, DELETE, etc.) and when should each be used?What are HTTP request methods (GET, POST, PUT, DELETE, etc.) and when should each be used?Apr 09, 2025 am 12:09 AM

HTTP request methods include GET, POST, PUT and DELETE, which are used to obtain, submit, update and delete resources respectively. 1. The GET method is used to obtain resources and is suitable for read operations. 2. The POST method is used to submit data and is often used to create new resources. 3. The PUT method is used to update resources and is suitable for complete updates. 4. The DELETE method is used to delete resources and is suitable for deletion operations.

HTTPS is a protocol that adds a security layer on the basis of HTTP, which mainly protects user privacy and data security through encrypted data. Its working principles include TLS handshake, certificate verification and encrypted communication. When implementing HTTPS, you need to pay attention to certificate management, performance impact and mixed content issues.
