Question

In a previous ticket i asked about logging PHP errors in MySQL which gives me:

function myErrorHandler($errno, $errstr, $errfile, $errline)
{
         // mysql connect etc here...
    $sql = "INSERT INTO `error_log` SET
            `number` = ".mysql_real_escape_string($errno).",
            `string` = ".mysql_real_escape_string($errstr).",
            `file` = ".mysql_real_escape_string($errfile).",
            `line` = ".mysql_real_escape_string($errline);
    mysql_query($sql);
    // Don't execute PHP internal error handler
    return true;
}

// set to the user defined error handler 
$new_error_handler = set_error_handler("myErrorHandler");

I can make this work but only if it is triggerred like this:

trigger_error("message here");

However, I also want the error handler to be called for all errors such as syntax errors like:

echo "foo;

But these errors are just outputted to the screen, what am i doing wrong?

You can only handle runtime errors with a custom error handler. The echo "foo error in your example happens when parsing (i.e. reading in) the source. Since PHP can not fully parse the code, it can also not run your error handler on this error.
