Description:
------------
When attempting to use the PDO class, Apache GPF's.
My PHP.ini reads as follows:
extension_dir = "C:\php\ext"
extension=php_pdo.dll
extension=php_pdo_odbc.dll
Apache/PHP doesn't alert me that the libraries couldn't be loaded.
The code provided is 100% reproducable on my system.
Removing all the code except the database connection doesn't crash. The code does say that the connection was established.
I'm not 100% sure if it's php or my php.ini file. The backtrace tells me that the class doesn't exist. That leaves me with a suspicion that it could be config related.
Reproduce code:
---------------
<?php
try {
$dbh = new PDO('odbc:IBMDB2', 'USER', 'PASS',
array(PDO_ATTR_PERSISTENT => true));
echo "Connected\n";
} catch (Exception $e) {
echo "Failed: " . $e->getMessage();
}
$email = "me@somewhere.com";
$stmt = $dbh->prepare("CALL SPROC(?, ?)");
$stmt->bindParam(1, $email);
$stmt->bindParam(2, $return_value, PDO_PARAM_STR, 80);
$stmt->execute();
print "procedure returned $return_value\n";
?>
Expected result:
----------------
Results from the database without error
Actual result:
--------------
(gdb) target exec C:\php\php.exe
(gdb) run test.php

Sounds like two different issues, neither of which is PDO specific ;-) Check that you were modifying the right php.ini file, and that you restarted apache after changing it. (phpinfo() will help you to figure that out). Your script is broken, btw. You catch the exception, effectively ignoring the error, and then continue to use the $dbh even though you "know" it isn't there. You should move that code inside the try {} block, just after you echo "Connected"; The GPF concerns me, but I suspect it will go away once you load PDO correctly. If you're feeling motivated, can you try pruning down your script to the smallest possible test case that reproduces the GPF? I'm hoping you can cut it down to something like this: <?php class foo { function __construct() { throw new Exception("bang"); } } try { $foo = new foo; } catch (Exception $e) { echo "Failed " . $e->getMessage(); } $foo->bar(); ?>Oops sorry about that. This fails with a gpf: <?php try { $dbh = new PDO('odbc:DATABASE', 'USER', 'PASS') $stmt = $dbh->prepare("SELECT * FROM TABLE"); } catch (Exception $e) { echo "Failed: " . $e->getMessage(); } ?> While this works just fine and prints "Connected", <?php try { $dbh = new PDO('odbc:DATABASE', 'USER', 'PASS') print "Connected\n"; } catch (Exception $e) { echo "Failed: " . $e->getMessage(); } ?> When I use exec, I don't get the GPF, but I'm also not getting the correct results. When trying to query a fake table, I don't get an error. When I query the correct table, I don't get a count. When I put in an incorrect database, user or password, I do get the correct error. So that tells me that I can connect to the database. <?php try { $dbh = new PDO('odbc:DATABASE', 'USER', 'PASS') print "Connected<br>"; $count = $dbh->exec("SELECT * FROM FAKETABLE"); print "Count: $count"; } catch (Exception $e) { echo "Failed: " . $e->getMessage(); } ?> I did verify the php.ini is correct. I put in a typo in the ini file to see if Apache will err on start up and it did. (brute force method :) ) Hope that's not too much information. --DavidWhen I installed the link you provided on my Windows machine, php/apache starts, but I get an error "Unable to load dynamic library 'C:\php\ext\php_pdo.dll' - the specified procedure could not be found.
