Php array has value

$myArr = [38, 18, 10, 7, "15"];

echo in_array(10, $myArr); // TRUE
echo in_array(19, $myArr); // TRUE

// Without strict check
echo in_array("18", $myArr); // TRUE
// With strict check
echo in_array("18", $myArr, true); // FALSE

In_array php

<?php
$os = array("Apple", "Banana", "Lemon");
if (in_array("Apple", $os)) {
    echo "Yeah. Exist Apple";
}
if (!in_array("Buleberry", $os)) {
    echo "Oh, Don't Exist Blueberry!!!";
}
?>

In_array php

<?php
$os = array("Mac", "NT", "Irix", "Linux");
if (in_array("Irix", $os)) {
    echo "Existe Irix";
}
if (in_array("mac", $os)) {
    echo "Existe mac";
}
?>
