有一篇文字$str
我现在需要替换这篇文字里的关键词$key
全部替换是

如何随机逐个替换,才能做到不重复的呢?
------解决方案--------------------
既然是“随机”,就不能避免重复
------解决方案--------------------
随机,逐个?听起来有点矛盾哦
------解决方案--------------------
描述的模模糊糊的。 你让key随机不就行了。
------解决方案--------------------
如果$key是数组,$k = array_rand($key,1);用$k进行替换
------解决方案--------------------
for($i=0;$i $string=str_ireplace("你好","你们好$i",$string);
}

Convert basic data types to strings using Java's String.valueOf() function In Java development, when we need to convert basic data types to strings, a common method is to use the valueOf() function of the String class. This function can accept parameters of basic data types and return the corresponding string representation. In this article, we will explore how to use the String.valueOf() function for basic data type conversions and provide some code examples to

Method of converting char array to string: It can be achieved by assignment. Use {char a[]=" abc d\0efg ";string s=a;} syntax to let the char array directly assign a value to string, and execute the code to complete the conversion.

What is Identity in SQL? Specific code examples are needed. In SQL, Identity is a special data type used to generate auto-incrementing numbers. It is often used to uniquely identify each row of data in a table. The Identity column is often used in conjunction with the primary key column to ensure that each record has a unique identifier. This article will detail how to use Identity and some practical code examples. The basic way to use Identity is to use Identit when creating a table.

1. Function Overview Keyspace notification allows clients to receive events that modify Rediskey changes in some way by subscribing to channels or patterns. All commands that modify key keys. All keys that received the LPUSHkeyvalue[value…] command. All expired keys in the db database. Events are distributed through Redis's subscription and publishing functions (pub/sub), so all clients that support subscription and publishing functions can directly use the keyspace notification function without any modifications. Because the current subscription and publishing functions of Redis adopt a fireandforget strategy, if your program

Replace characters (strings) in a string using Java's String.replace() function In Java, strings are immutable objects, which means that once a string object is created, its value cannot be modified. However, you may encounter situations where you need to replace certain characters or strings in a string. At this time, we can use the replace() method in Java's String class to implement string replacement. The replace() method of String class has two types:

Hello everyone, today I will share with you the basic knowledge of Java: String. Needless to say the importance of the String class, it can be said to be the most used class in our back-end development, so it is necessary to talk about it.

An unpatchable Yubico two-factor authentication key vulnerability has broken the security of most Yubikey 5, Security Key, and YubiHSM 2FA devices. The Feitian A22 JavaCard and other devices using Infineon SLB96xx series TPMs are also vulnerable.All

Problems encountered: During the development process, you will encounter keys that need to be deleted in batches according to certain rules, such as login_logID (ID is a variable). Now you need to delete data such as "login_log*", but redis itself only has batch query. Command keys for class key values, but there is no command for batch deletion of a certain class. Solution: Query first, then delete, use xargs to pass parameters (xargs can convert pipe or standard input (stdin) data into command line parameters), execute the query statement first, and then remove the queried key value and the original del parameters. delete. redis-cliKEYSkey* (search condition)|xargsr
