meet it

Ask an array for its biggest, smallest and total.

hands back the biggest item in an array and the smallest. array_sum adds every item up, so a total does not always need a loop.

checks whether a value is in the array. Put the value first, then the array: in_array(19, $temps). It gives true or false, so it fits straight into an if.

To find the first item that matches a question, loop with foreach, check each item with an if, and break as soon as you find it.

<?php
$temps = [14, 19, 11, 17];
echo "Hottest: " . max($temps) . "\n";
echo "Coldest: " . min($temps) . "\n";
echo "All added up: " . array_sum($temps) . "\n";
if (in_array(19, $temps)) {
    echo "We had a 19 degree day!\n";
}

in_array looks for an exact match, so "Dog" with a capital D will not find "dog".

guess first

Find the first name with 3 letters. What will this show?

Guess before you run it. Wrong guesses are how you learn, and nothing is marked.

<?php
$names = ["Al", "Ben", "Cleo", "Dee"];
foreach ($names as $name) {
    if (strlen($name) === 3) {
        echo "Found $name\n";
        break;
    }
}

your turn

Your turn. Find the first long snack.

Type three snacks. Make sure at least one has more than 5 characters, then run it to find the first long one.

fix it

There is an apple in there. Why the crash? Fix it.

Broken code to fix

press run to see what happens

Read the error: in_array wanted an array second, but it got a string. Look at the order inside the brackets.
in_array needs the value to look for first, then the array to look in.
Swap them so line 3 says in_array("apple", $snacks), then press run.

nailed it

you can search an array like a detective. :D

max, min and array_sum work on a whole array.
in_array(value, array) gives true or false.
Loop, check each item, and break when you find it.
