why do I have an extra item in my array?

trying to explode url to get sections

[HelenDev]

Why is my code...

$urlarray = explode("/", "/about/new/index.php");
print_r($urlarray);

...returning this...

Array ( [0] => [1] => about [2] => new [3] => index.php )

Perhaps I am being dense but why do I have an extra empty value at the beginning of the array? I was expecting only 3 items.

Is there any way I can make it return the ones I want (ie only those containing an actual value) or do I simply have to work around this?

$urlarray = explode("/", "/about/new/index.php");
print_r($urlarray);

Removing the first backslash will give you the result you are looking for. $urlarray[0] is the empty value before the first backslash, so removing it will remove the $urlarray[0].

It should be like this:
$urlarray = explode("/", "about/new/index.php");
print_r($urlarray);

Thanks Habtom. I wondered if it was something like that.

The problem is that I'm actually using $_SERVER["PHP_SELF"] to get the URL. What's the easiest way to remove the initial slash from this?

[jatar_k]

[php.net...]

$url = substr($_SERVER['PHP_SELF'],1);

that will return the string minus the first char

Thanks jatar_k. Perfect :)
