How to convert array to list in php

In PHP development, arrays and lists are two commonly used data structures. An array is a simple data structure that consists of numeric subscripts and corresponding values. A list is a complex data structure that consists of multiple elements, and each element can contain multiple values.

In many scenarios, we need to convert arrays into lists. At this time, we can use PHP's built-in functions to achieve this.

Here is an example that demonstrates how an array is converted into a list:

<?php

$my_array = array(&#39;apple&#39;, &#39;banana&#39;, &#39;cherry&#39;);

// 使用 implode 函数将数组转换成字符串
$my_string = implode(&#39;, &#39;, $my_array);

// 使用 explode 函数将字符串转换成列表
$my_list = explode(&#39;, &#39;, $my_string);

// 输出结果
print_r($my_list);

?>

The above code first creates an array of three elements and then uses implode() Function concatenates arrays into a comma- and space-separated string. Next, we use the explode() function to convert the string into a list, separated by commas and spaces. Finally, we use the print_r() function to output the converted list.

Run the above code, we will see the following output:

Array
(
    [0] => apple
    [1] => banana
    [2] => cherry
)

The above output is the converted list. We can see that it is exactly the same as the original array, except that the data type is changed to a list.

In addition to using the implode() and explode() functions, you can also use the array_values() function to copy all the values ​​of the array to a new In the index array, get a list with the same values ​​as the original array. The following is a code example:

<?php

$my_array = array(&#39;apple&#39;, &#39;banana&#39;, &#39;cherry&#39;);

// 使用 array_values 函数将数组转换成索引数组
$my_list = array_values($my_array);

// 输出结果
print_r($my_list);

?>

In the above code, we use the array_values() function to copy all the values ​​of the original array to a new index array. Finally, we use the print_r() function to output the converted list.

Run the above code, we will see the following output:

Array
(
    [0] => apple
    [1] => banana
    [2] => cherry
)

The same as the previous code sample output, the above output is also a converted list, which is exactly the same as the original array, except The data type becomes a list.

To summarize, there are many ways to convert arrays into lists in PHP. In addition to using the implode() and explode() functions, you can also use the array_values() function to copy all the values ​​of an array into a new indexed array . These functions are very simple and easy to use. We can choose the function that suits us according to the actual situation to achieve conversion between arrays and lists.
