Removing empty items from an array ?

[Floodboy]

I just can't figure out how to do this, I was trying to do this but didn't work 🙁

function remove($myarray){
	if (in_array(" ", $myarray)){
		foreach($myarray as $show){
			if(($show == " ") || (empty($show))){
				unset($show);
				exit();
			}
		}
		exit();
	}
	return $myarray;
}

Any ideas ?

You're unsetting the temporary variable name, not the array. I'm a little tired, but what you want to do is get the key, then unset the actual array key that is empty. Something like this

function remove($myarray){
    if (in_array(" ", $myarray)){
        foreach($myarray as $key => $value){
            if(($value == " ") || (empty($value))){
                unset($myarray["$key"]);
            }
        }
    }
    return $myarray;
}

It worked but what if $myarray comes from

trim($_POST['name']);
$myarray = explode(" ", $_POST['name']);

What I want to do is remove all the spaces from the $_POST

so if in the input form someone writes "John (5 spaces) Smith "

transform this into "John Smith" my idea was to explode this, then remove empty values in the array and then implode the new array with just one space :p

Try:

$s = "John     Smith";
echo preg_replace("/\s+/","\040",$s);

Edit: Had to use the code tags, what is up with the php tags?

thanks a lot 😃

I didn't used preg_replace before can you please explain me a bit what means

040

I know regex from Perl, but I don't know the meaning of those numers, or can you give me a reference to read about it ?

Thanks 🙂

Sorry I should've explained. 040 is octal for the space character. Check out futher information here:
