Question

I’m just converting a site to PDO and this is my first exposure to it, but I’m having difficulty obtaining any kind of useful error information from PDO. I’ve read numerous other posts on this subject but none of them seem to provide a solution which works for me.

Here is the code:

try {
    $dbh    = new PDO("mysql:host=".CO_DB_HOST.";dbname=".CO_DB_NAME, CO_DB_UNAME, CO_DB_PWORD);

    $dbh    ->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
}
catch(PDOException $e) {
    echo $e->getMessage();
}


function addRec($data) {

    global $part_id, $dbh;
    $part_id++;

    try {
        $sth=$dbh->prepare("
            INSERT INTO 
                non_existent_table
                (
                    name
                ) VALUES (
                    ?
                );
        ");

        for ($i = 0; $i < count($data); $i++) {
            $sth->execute($data[$i]);
        }
    }

    catch(PDOException $e) {
        echo "Something went wrong. Please report this error.";
        file_put_contents('/PDOErrors.txt', PDOStatement::errorInfo(), FILE_APPEND);
    }
}

// Insert a database record
$data = array(
        array(
            'joe blogs',    /* name */
        )
);
addRec($data);

The table does not exist but I’m getting no error in PDOError.txt and nothing in my httpd error log. Can someone shed some light on what I’m doing wrong please? Thanks.

Answer 1

errorInfo() is not a static method. Also, it returns an array, not a string.

You should be fine with the information in the exception. Use something like this instead

file_put_contents('/PDOErrors.txt', $e->getMessage(), FILE_APPEND);

For extra information, you could also append the stacktrace.

Edit

Are you sure /PDOErrors.txt is the correct file path for your error log? That’s in the filesystem root which I doubt is what you want or even possible.
