How to split a string into an array in PHP

Use the PHP explode() function

You can use the PHP explode() function to split or break a string into an array by a separator string like space, comma, hyphen etc. You can also set the optional limit parameter to specify the number of array elements to return. Let's try out an example and see how it works:

<?php
$my_str = 'The quick brown fox jumps over the lazy dog.';
print_r(explode(" ", $my_str));
echo "<br>";
print_r(explode(" ", $my_str, 4));
?>
