Exceptions¶
Zephir implements exceptions at a very low level, providing similar behavior and functionality to PHP.
When an exception is thrown, a catch block can be used to capture the exception and allow the developer to provide proper handling.
Exceptions can be thrown inside the try block. Handling happens in the catch block, exactly as in PHP:
var e;
try {
throw new \Exception("This is an exception");
} catch \Exception, e {
echo e->getMessage();
}
Zephir also provides a "silent" try block, that simply ignores any exceptions produced within that block:
If you don't need an exception variable when 'catch'ing, then you can safely not provide it:
try {
throw new \Exception("This is an exception");
} catch \Exception {
echo "An exception occur!";
}
A single catch block can be used to catch multiple types of exception:
var e;
try {
throw new \Exception("This is an exception");
} catch \RuntimeException|\Exception, e {
echo e->getMessage();
}
Zephir allows you to throw literals or static typed variables as if they were the message of the exception:
// throw new \Exception("Test");
throw "Test";
// throw new \Exception((string) 't');
throw 't';
// throw new \Exception((string) 123);
throw 123;
// throw new \Exception((string) 123.123);
throw 123.123;
Zephir's exceptions provide the same methods to know where the exception happened that PHP's exceptions do. That is, Exception::getFile() and Exception::getLine() return the location in the Zephir code where the exception was thrown:
