Catch
catch is the complement clause of try. It defines which exception is caught. Optionally, it defines which variable holds the exception when it happens, since PHP 8.0.
Multiple catches may be used. They are applied in the order of writing, and the first clause which succeed is the last.
It is possible to catch multiple exceptions at the same time: in that case, the second exception is chained.
<?php
try {
callSomeMethod();
} catch (\SomeException $e) {
display("Warning");
} catch (\SomeSeriousException $e) {
display("Alert");
} catch (\Exception) {
// process the error here
}
?>
