array_push question

[Anon]

I set up a function to clean up some form fields, however I can't seem to push the values in to a new array. When I run this, only garbage is returned. Hopefully someone can see what I'm missing.

Thanks,

Andrew

Here's the function and calling method:

<?
function cleanHTML($html) {
$cleanFields = array();
foreach ($html as $key => $value) {
array_push($cleanFields, $key[nl2br(htmlspecialchars($value))]);
}
return $cleanFields;
} # END function cleanHTML
?>

<?
$cleanFields = cleanHTML($HTTP_POST_VARS);
foreach ($cleanFields as $blah => $blam) {
echo "Key: $blah; Value: $blam<br>\n";
}
?>

Well, what's going on here?

array_push($cleanFields, $key[nl2br(htmlspecialchars($value))]);

Looks like you are trying to push the value of $key where the index is
nl2br(htmlspecialchars($value))

I doubt this is what you want.

If you just want to clean the content of the array, why not just assign it directly?
$cleanfields=array()
foreach(...)
{
$cleanfields[$key]=nl2br(htmlspecialchars($value));
};
