How Can I Split a String into an Array Using Newline Characters in PHP?

Using PHP to Split a String by Newline Characters

When working with string data, it's often necessary to split it into an array based on specific delimiters. One common delimiter is new line characters. This allows you to parse strings containing line breaks into individual elements of the array.

Split String into Array by Newline Characters

To split a string with new line characters in PHP, you can use the preg_split() function. This function takes a regular expression as its first argument and a string as its second argument. The regular expression specifies the delimiter pattern you want to use for splitting.

Example:

Consider the following string:

My text1
My text2
My text3

To split this string into an array by newline characters, you can use the following code:

$array = preg_split("/\r\n|\n|\r/", $string);

Explanation:

The regular expression used in this code is:

/\r\n|\n|\r/

This regular expression matches three different types of newline characters: rn (carriage return followed by a line feed), n (line feed), and r (carriage return). By using a vertical bar (|) between these three patterns, it matches any of these characters as a delimiter.

Result:

The resulting array will look like this:

Array
(
    [0] => My text1
    [1] => My text2
    [2] => My text3
)

This array now contains individual line breaks from the original string, providing you with a convenient way to work with each line separately.
