With a bit of rooting about with reflection, I spotted that the mysqli_warning class has a next()
function, so I tried calling it and it does indeed progress through the available warnings!
Following on from my earlier example:
<?php
$r = mysqli_query($db, "INSERT INTO blah SET z = '1'");
$j = mysqli_warning_count($db);
if ($j > 0) {
$e = mysqli_get_warnings($db);
for ($i = 0; $i < $j; $i++) {
var_dump($e);
$e->next();
}
}
?>
This is a pretty rubbish interface - it's clearly a kind of half-baked iterable / traversable,
but doesn't advertise those interfaces. It's actually more code than doing and processing
a SHOW WARNINGS query manually!
