How does one shave arrays?

[ipruthi]

Hi,

I'm having trouble shaving some neighboring arrays :-) Seriously, this thing is driving me crazy! The concept is that I am submitting a form that collects its data into an array called $form. So the data are something like: $form[username], $form[password], $form[password2], etc.

The thing is that I want to trim any white spaces before or after the value in each field of my array. This is what I did on the top of the file.

<?

//Check to see if goal is to register
if ($what == "register")
{

$form = trim($form);

//I'm doing this below to check if the
//array's been shaved off. But it is not
//working though.
foreach ($form as $temp)
{
print "$idiot<br>";
}
}

?>

The thing is that the $form element-array is not being shaved off (boy do I like the term "shave off" this night). Anyone has a solution to my everlasting problem?

Well, anyhow, thanks in advance.

Ilir.

When using a form, HTML translates spaces to "&nbsp;" so you need to do a search for that particular character (chr 160).

Try this (found on the PHP.net site):

$str = str_replace( chr( 160 ), '', $str );

Hope it helps!

Maybe this:

foreach ($arr as $key => $value) {
trim($value);
echo($value."<br>");
}

This should trim any and all white space (spaces, tabs, cr/lf's)...
