+PHP has a huge standard library with the most extravagant and highly specific string and array functions available. 
+`levenshtein` & `array_change_key_case` anyone??
+
+On the flip side, historically it has missed some very common string operations. There's always been a way to get the same results, but they are cumbersome and error prone.
+
+For example, if you want to check if a string contains a string you might use `strpos`. Eg:
+
+```php
+if (strpos('colourful', 'colour')) {
+}
+```
+Well, this check will fail because `strpos` will return `0` which will be interpreted as false. You will need to adapt that check to account for 0 with `strpos('colourful', 'colour') !== false` where the strict comparison is important.
+
+Thankfully, PHP 8 has done away with all that nonsense. Please welcome the following functions in to the world of PHP:
+
+* `str_contains`
+* `str_starts_with`
+* `str_ends_with`
+
+----------------------------------------------------------------------
+
+Create a program the accepts two arguments, the first is a word, the second is a sentence (random words).
+
+You must print a table which contains the results of each of the above functions with the provided word and sentence.
+
+* First, does the sentence contain the word?
+* Second, does the sentence start with the word?
+* Lastly, does the sentence end with the word?
+
+You will use the composer package `symfony/console` to print a table using the `Table` helper.
+
+The table headers should be `Function` & `Result`
+
+There should be three rows, one for each function. The function column should contain the function name, eg `str_contains`.
+The result column should be `true` or `false` based on the result of the corresponding function call.
+
+### The advantages of the new string functions
+
+* Simpler and more concise.
+* Saner return types.
+* It is harder to get their usage wrong, for example checking for 0 vs false with `strpos`
+* The functions are faster, being implemented in C.
+* The operations require less function calls, for example no usages of `strlen` are required.
+
+----------------------------------------------------------------------
+## HINTS
+
+Point your browser to [https://getcomposer.org/doc/00-intro.md](https://getcomposer.org/doc/00-intro.md) which will walk you through **Installing Composer** if you haven't already!
+
+Use `composer init` to create your `composer.json` file with interactive search.
+
+For more details look at the docs for...
+
+**Composer** - [https://getcomposer.org/doc/01-basic-usage.md](https://getcomposer.org/doc/01-basic-usage.md)
+**Symfony Console** - [https://symfony.com/doc/current/components/console.html](https://symfony.com/doc/current/components/console.html)
+**str_contains** - [https://www.php.net/manual/en/function.str-contains.php](https://www.php.net/manual/en/function.str-contains.php)
+**str_starts_with** - [https://www.php.net/manual/en/function.str-starts-with.php](https://www.php.net/manual/en/function.str-starts-with.php)
+**str_ends_with** - [https://www.php.net/manual/en/function.str-ends-with.php](https://www.php.net/manual/en/function.str-ends-with.php)
+
+For Symfony Console you will want to look specifically for the Table Helper.
+
+Oh, and don't forget to use the Composer autoloader with:
+
+```php
+require_once __DIR__ . '/vendor/autoload.php';
+```
