怎样在数组中插入一个值
$arr1=array(1,4,5,7,9,15,18,20);
假设在5的后面插入一个6,并输出数组
1,4,5,6,7,9,15,18,20

------解决方案--------------------
你头像换得蛮快嘛...如果不是升序的话.... 这是刚写的函数,如果需要插入多个自己修改吧.

PHP code
$arr1 = array (1, 4, 5, 7, 9, 15, 18, 20 );print_r ( input_array ( $arr1, 5, 6 ) );function input_array($array, $value, $input) {    $key = array_search ( $value, $array );    if ($key !== false) {        array_splice ( $array, $key, 1, array ($array [$key], $input ) );        return $array;    }    return false;}<div class="clear">
                 
              
              
        
            </div>

Detailed explanation of the usage of return in C language Detailed explanation of the usage of return in C language Oct 07, 2023 am 10:58 AM

The usage of return in C language is: 1. For functions whose return value type is void, you can use the return statement to end the execution of the function early; 2.

How SpringBoot monitors redis Key change events How SpringBoot monitors redis Key change events May 26, 2023 pm 01:55 PM

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

How to solve the problem of batch deletion of key values ​​in redis How to solve the problem of batch deletion of key values ​​in redis May 31, 2023 am 08:59 AM

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
