PDO exception error

code does not seem to be picking up the PDOException

[topr8]

test environment:
Apache 2.2 on windows xp

i'm using the most basic script:

try {

$dbh = new PDO('mysql:host=localhost;dbname=db', 'user', 'password');

echo "<p>Connection SUCCESS!</p>";

// disconnect
$dbh = null;
}
catch (PDOException $e) {
die($e->getMessage());
}

if i run this script with the correct username and password then naturally the success message is displayed, thus i assume pdo is installed properly.

however if i enter an incorrect username, password or database name then i was expecting to get the 'catch' error message written to the page.

but, i'm getting this message:

Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[28000] [1045] ....etc,etc.

which means to me that the exception is not being caught.
as this script is about as simple as it gets, i'm wondering if i'm missing the point - surely if i enter an incorrect username it should throw an exception and the script should catch it!

any ideas?

ok, i've been looking at this and trying some other examples that i've got from either books or the web

i can't get my code to 'catch' ANY of the exceptions that i have tried...

is there something i need to configure?

i'm using php 5.2.1

Try the basics first, start with the sample code on the PHP Exceptions [php.net] manual page. Or better yet and even more simple, use the example on the getMessage [php.net] method page.

something odd is happening!

i cut and pasted the getMessage example which is as simple as it gets.

and it fails, the error i get is the same-
Fatal Error:uncaught exception ...

if i try the getMessage example with the following code pasted above it:

/*** a default Exception handler ***/
function my_default_handler($exception){
echo "Uncaught exception: " , $exception->getMessage();
}
set_exception_handler('my_default_handler');

then the default handler catches it and the followign message is printed to the page:

Uncaught exception: Some error message

which is correct, in that the default exception handler is obviously catching the exception.

.....
just to be clear, the exact code i initially used is..

<?php

try {
throw new Exception("Some error message");
} catch(Exception $e) {
echo $e->getMessage();
}
?>

and it throws up the: Fatal error, uncaught exception message.

i'm testing this in a file in the root, there is no .htaccess or anything that i imagine could be interfering with the code.

seems very strange to me!

Looks to me like there is an exception handler in effect already.

When an exception is thrown, code following the statement will not be executed, and PHP will attempt to find the first matching catch block. If an exception is not caught, a PHP Fatal Error will be issued with an "Uncaught Exception ..." message, unless a handler has been defined with set_exception_handler() [php.net].

My emphasis added

Resource: Exceptions [php.net]

I have run into existing exception handler overrides before. I use the set_exception_handler() function to override temporarily with my own and then reset it after I am completed with my portion of the processing. The function will return ... well, here ... read it right from the manual pages ...

Return Values

Returns the name of the previously defined exception handler, or NULL on error. If no previous handler was defined, NULL is also returned.
