php carriage return to array

PHP is a widely used server-side scripting language that can be used to build dynamic web applications. In PHP, handling strings is one of the required operations.

Sometimes, we need to convert a string containing multiple lines of text into an array. At this time, we can use the PHP built-in function explode to split this string into an array using the carriage return character `
`.

The following is a code example that uses the carriage return character to convert to an array in PHP:

// 定义一个包含多行文本的字符串
$text = "Hello
World
This is a
Multiline text
";

// 使用explode函数将字符串使用回车符分割为数组
$array = explode("
", $text);

// 输出数组
print_r($array);

The above code will output the following results:

Array
(
    [0] => Hello
    [1] => World
    [2] => This is a
    [3] => Multiline text
)

is used in the code explode function, the first parameter is the delimiter used to split the string. Here we use the carriage return character `
as the delimiter. The second parameter is the string variable to be split, and the explode` function returns an array consisting of the split strings.

Now we can use normal array functions to operate on the array, such as count, foreach, etc.

In addition to the carriage return character, there are some other delimiters that can be used to split a string into an array, such as comma, semicolon, space, etc. It depends on how you want to split it and what type of data you want.

Using the above techniques, we can easily convert a string containing multiple lines of text into an array, and then perform subsequent operations.
