PHP
Conditionals
if, elseif, and else work the
same as most C-family languages, each block wrapped in curly braces,
condition in parentheses.
Example: a time-of-day greeting
<?php
$hour = 14;
if ($hour < 12) {
echo "Good morning";
} elseif ($hour < 18) {
echo "Good afternoon";
} else {
echo "Good evening";
}
?>Good afternoonNote the spelling: PHP uses elseif as one word (though
else if as two words also works), a small but real
difference from JavaScript's else if, worth knowing so it
doesn't trip you up switching between languages.
<?php
$hour = 14;
if ($hour < 12) {
echo "Good morning";
} elseif ($hour < 18) {
echo "Good afternoon";
} else {
echo "Good evening";
}
?>Good afternoon
