PHP String Exercises: Put a string in an array

Sample Solution:

PHP Code:

<?php
// Define a multi-line string containing the lyrics of a song
$str = "Twinkle, twinkle, little star,\nHow I wonder what you are.\nUp above the world so high,\nLike a diamond in the sky.";

// Explode the multi-line string into an array using "
" as the delimiter
$arra1 = explode("<br>", $str);

// Display the array containing the lines of the song
var_dump($arra1);
?>

Output:

array(1) {                                                  
  [0]=>                                                     
  string(112) "Twinkle, twinkle, little star,               
How I wonder what you are.                                  
Up above the world so high,                                 
Like a diamond in the sky."                                 
}

Explanation:

In the exercise above,

It defines a multi-line string variable $str, which contains the lyrics of a song. Each line is separated by the newline character \n.
It uses the "explode()" function to split the multi-line string $str into an array $arra1. The delimiter used for splitting is <br>, which implies that the function is attempting to split the string at occurrences of <br>.
Finally, it displays the contents of the array $arra1 using var_dump(), which shows each element of the array (i.e., each line of the song) along with its index.
