Spliting a string

Anon

Hi,

I need to split a domain name (Using PHP3) taking everything to the left of the "." in the domain anme and assign it into a variable named $Name

Example
if
$domain = "test.com" or
$domain = "test.net"
then
$Name should equal "test"

Basiclly, I need everything to the left of the "."
I have tried several methods but all have failed to get the result I needed.If anyone caould help it would be appreciated.

Thanks in advance,
Joe

Joe,

Here's what I will suggest you to do.

For example, $domain ="test.com"

$temp=split(".",$domain);
$Name=$temp[0];

with these codes, you should be able to put everything to the left of the . to the variable $Name.

Hopefully it helps you.

Regards,
CL

Hi,

Thanks... that did it! I just had to escape out the period and it worked...

$temp=split(".",$domain);

Thanks again for taking the time out to reply.

Now what if you have a domain like store.yahoo.com You will only get the first part which would be store. In which case you would need to:

$temp = explode(".", $domain);
if (count($temp) > 2) {
for($i=0;$i<count($temp) - 1;$i++) {
$left .= $temp[$i].".";
}
}
else {
$left = $tmp[0];
}

Right, a host-name can have any number of dots. If you know you always want the leftmost part, or always want the top-level-domain part, you could right a regex to split the string at the first or last dot.

the split \ replace functions does not recoganize "\" charcter.

example:
i need to take just the file name (new.gif) from this dynamic string.

"C:\windows\programfiles\new.gif"

i did the following

var arr;
var len;
var fil;
var temp
temp= "C:\windows\programfiles\new.gif";
arr = temp.split("\");
len = arr.length;
fil = arr[len-1];
alert(fil);

it gave me an error.

if i give the following

var arr;
var len;
var fil;
var temp
temp= "C:windows:programfiles:new.gif";
arr = temp.split(":");
len = arr.length;
fil = arr[len-1];
alert(fil);

it worked !

how can i solve this problem ?

try use "\" instead of "\"
