In fact, PHP debugging can be adjusted at any time, where you want to tune, the simplest is where the output. Of course Zend-studio also provides a breakpoint function debugging, but far less convenient.
In fact, each has its own advantages, brother, or from the bar.

You also need to throw an exception in the try{} statement block, throw new Exception (' It is a exception! '), and then capture by catch (Exception $e).

Use Echo to find the anomaly, PHP can't.

Then go to see PHP error_log ah ... There will be a variety of detailed error messages .... What else can catch ...
------Solution--------------------
There are basically two types of errors, one that can be captured by PHP, such as syntax errors. There is also a logical error that the machine does not capture, so the try catch is used to capture the artifact.
I think you said the error is just the previous one, then open the error prompt display_errors = On, you can see.

Your code is no exception, of course, will not execute that sentence

Reference:

PHP Code

try{
$a = "SGFDFGDF";
$b = (int) $a;
Echo ($b);
}
catch (Exception $e) {
Echo ("Error". $e->getmessage ());//Here and the wood is executed.
}

shaping Conversion Errors It's not a mistake.

Coercion of type conversions is not an error in any language!
Although sometimes you don't get the results you expect.

PHP error exceptions are similar to Java, but they are usually thrown on their own: examples:
try{
$m = 0;
if ($m < 1) {
throw new Exception (' m= '. $m. ': Less than 0 ');
}
Echo $m;
} catch (Exception $e) {
echo "Error [line->". ( $e->getline ()). "]:". ($e->getmessage ());
}

PHP Weak type change data type no problem

Let the divisor be 0, and you'll see the throw anomaly.
