Dece-mi arata doar cele gresite intr-un cod php? Adica, cand rulez nu-mi apare varianta pe care o vreau, ci opusul.

<?php
$color = "red";
echo "My car is " . $color . "
";
echo "My house is " . $COLOR . "
";
echo "My boat is " . $coLOR . "
";
?>


Inloc sa-mi apara my car is red, imi apare celalalte doua gresite ( my house is...my boat is...).
