用for给数组赋值
$tests=array(id => "910003", params => array("param1" => '', "param2" => '', "param3" => ''));for ($i = 0; $i <= count($tests["params"]); $i++) { }
如何用上述方法修改param1,param2,param3值?
回复讨论(解决方案)
$i <= count($tests["params"])
应为
$i < count($tests["params"])
$tests = array('id' => "910003", 'params' => array("param1" => '', "param2" => '', "param3" => ''));foreach($tests["params"] as $k=>&$t) $t = $k;print_r($tests);
Array( [id] => 910003 [params] => Array ( [param1] => param1 [param2] => param2 [param3] => param3 ))
$tests = array('id' => "910003", 'params' => array("param1" => '', "param2" => '', "param3" => ''));for($i=1; $i<=count($tests["params"]); $i++) { $tests["params"]['param'.$i] = $i;}print_r($tests);
Array( [id] => 910003 [params] => Array ( [param1] => 1 [param2] => 2 [param3] => 3 ))
谢谢!,如果这个参数名是没有规律的(如:param_23、paramAbc……),那有如何实现
不是给了你两个方案了吗?
哦,明白了!谢谢!
$tests=array('id' => "910003", 'params' => array( "param1" => '', "param2" => '', "param3" => '' ));for ($i = 1; $i<=count($tests["params"]); $i++) { $tests['params']['param'.$i]=$i;}print_r($tests['params']);

如果没有规律,只能换一种办法了

The method of using a foreach loop to remove duplicate elements from a PHP array is as follows: traverse the array, and if the element already exists and the current position is not the first occurrence, delete it. For example, if there are duplicate records in the database query results, you can use this method to remove them and obtain results without duplicate records.

Methods for deep copying arrays in PHP include: JSON encoding and decoding using json_decode and json_encode. Use array_map and clone to make deep copies of keys and values. Use serialize and unserialize for serialization and deserialization.

The performance comparison of PHP array key value flipping methods shows that the array_flip() function performs better than the for loop in large arrays (more than 1 million elements) and takes less time. The for loop method of manually flipping key values takes a relatively long time.

This article will show you how to enable or disable automatic copying of selections to the clipboard in Windows Terminal. Windows Terminal is a multi-tab terminal emulator developed by Microsoft specifically for Windows 11/10, replacing the traditional command prompt. It supports running applications such as Command Prompt, PowerShell, WSL, Azure, etc. Often when working in the terminal, users need to copy commands and output, however the terminal does not support copying selection operations by default. Keep reading this article to learn how to fix this issue. How to enable or disable automatic copying of selections to cache in Terminal? Here's how you can enable or disable automatic copying of selections to the Terminal clipboard: Open the Terminal application and click above

The best practice for performing an array deep copy in PHP is to use json_decode(json_encode($arr)) to convert the array to a JSON string and then convert it back to an array. Use unserialize(serialize($arr)) to serialize the array to a string and then deserialize it to a new array. Use the RecursiveIteratorIterator to recursively traverse multidimensional arrays.

PHP's array_group_by function can group elements in an array based on keys or closure functions, returning an associative array where the key is the group name and the value is an array of elements belonging to the group.

Multidimensional array sorting can be divided into single column sorting and nested sorting. Single column sorting can use the array_multisort() function to sort by columns; nested sorting requires a recursive function to traverse the array and sort it. Practical cases include sorting by product name and compound sorting by sales volume and price.

The PHP array merging and deduplication algorithm provides a parallel solution, dividing the original array into small blocks for parallel processing, and the main process merges the results of the blocks to deduplicate. Algorithmic steps: Split the original array into equally allocated small blocks. Process each block for deduplication in parallel. Merge block results and deduplicate again.
