PHP Non-capturing Catches

Description

Since PHP 8.0, exceptions are allowed without capturing them into variables1.

Syntax

Pre PHP8

try {
    changeImportantData();
} catch (PermissionException $ex) {
    echo "You don't have permission to do this";
}

Post PHP8

try {
    changeImportantData();
} catch (PermissionException) { // The intention is clear: exception details are irrelevant
    echo "You don't have permission to do this";
}
