In PHP, you can split a string into an array by using the explode() function. The function takes two arguments - the separator and the string to be split. It separates the string at the positions where the separator occurs and returns an array of substrings.
Example 1: Splitting a string with a space separator
$string = "Hello World!";
$parts = explode(" ", $string);
print_r($parts);
Output:
Array
(
[0] => Hello
[1] => World!
)
Example 2: Splitting a string with a comma separator
$string = "apple,banana,grape";
$parts = explode(",", $string);
print_r($parts);
Output:
Array
(
[0] => apple
[1] => banana
[2] => grape
)
Example 3: Splitting a string with a hyphen separator
$string = "PHP-is-awesome";
$parts = explode("-", $string);
print_r($parts);
Output:
Array
(
[0] => PHP
[1] => is
[2] => awesome
)
