Conditionals: if/else, switch, match

Master conditional logic with if/else, switch, and the modern match expression.

If/Else

\$score = 85;
if (\$score >= 90) {
    echo "A";
} elseif (\$score >= 80) {
    echo "B";
} else {
    echo "C";
}

Switch

switch (\$day) {
    case 1: echo "Mon"; break;
    case 2: echo "Tue"; break;
    default: echo "Unknown";
}

Match Expression (PHP 8.0+)

\$result = match (\$status) {
    200 => "OK",
    404 => "Not Found",
    500 => "Server Error",
    default => "Unknown",
};

Unlike switch, match is an expression (returns a value) and does strict comparison (===).

Examples

<?php
$age = 20;
$status = match(true) {
    $age < 13 => 'Child',
    $age < 20 => 'Teen',
    $age < 65 => 'Adult',
    default => 'Senior',
};
echo $status;
