striping some thing from a variable

[prakash]

suppose

 

$var="http://www.website.com";

$var="http://website.com";

$var="www.website.com";

$var="http://www.www.com";

$var="http://www.com";

 

so how can I stripe http:// or http://www or www of the above var using php

 

output must be

 

website.com

www.com

[phpQuestioner]

<?php

$var="http://www.google.com";

$myvar = explode(".", $var);

echo $myvar[0];
echo $myvar[3];

?>

 

you will need an array for multiple values in one variable.

[prakash]

<?php

$var="http://www.google.com";

$myvar = explode("//", $var);

echo $myvar[1];

?>

 

you will need an array for multiple values in one variable.

 

this will produce www.google.com or www.www.com

but I need to produce only google.com and www.com

 

any idea

[phpQuestioner]

try my code again - I had to correct it

[yzerman]

parse_url($var, PHP_URL_HOST);

[kenrbnsn]

Here's a solution that uses the parse_url() function:

<?php
$vars = array();
$vars[]="http://www.website.com";
$vars[]="http://website.com";
$vars[]="www.website.com";
$vars[]="http://www.www.com";
$vars[]="http://www.com";
foreach($vars as $url) {
   echo 'Original url: ' . $url . "<br>\n";  //debug
   if (strtolower(substr($url,0,7)) != 'http://') $url = 'http://' . $url;
   $tmp = parse_url($url);
   $tmp2 = explode('.',$tmp['host']);
   if (count($tmp2) > 2) $dmp = array_shift($tmp2);
   echo implode('.',$tmp2)."<br>\n";
}
?>

[phpQuestioner]

Actually, I think you will need to use explode_assoc().

 

Update: Skip the above statement I just made - do this:

 

<?php

$var="http://www.google.com";

$myvars = explode(".", trim($var, "http://"));

echo $myvars[0];
echo ".";
echo $myvars[2];

?>

[prakash]

I finally made my own

 

$var="http://www.site.com";

$var="http://www.subdomain.site.com";

$var="http://www.www.site.com";

$var="http://www.www.com";

$var="www.com";

$var="http://www.phpfreaks.com/forums/index.php?action=post;topic=171945.0;num_replies=6";

 

etc....

 

<?php
$query=parse_url(htmlspecialchars(trim($var)), PHP_URL_HOST);
$myvar= explode(".", $query);
$totalIndex=count($myvar);
$ext=$myvar[$totalIndex-1];
$domainName=$myvar[$totalIndex-2];
$query=$domainName.'.'.$ext;
?>

 

just tested and works gr8 for every urls

[prakash]

UPDATE: not working for urls like www.com or site.com

any help?

[phpQuestioner]

try this:

 

<?php

$var="http://www.site.com";

$myvars = explode(".", trim($var, "http://"));

$query="". $myvars[0] .".". $myvars[2] ."";

?>

[kenrbnsn]

Use the code I posted. It works for all of the examples you have shown so far.

that code doesn't work for http://www.subdomain.site.com or http://www.www.site.com,

[kenrbnsn]

Yes it does. Here are the results I get for those two examples:

Original url: http://www.subdomain.site.com
subdomain.site.com
Original url: http://www.www.site.com
www.site.com
Original url: www.subdomain.site.com
subdomain.site.com
Original url: www.www.site.com
www.site.com

 

Ken

[prakash]

Yes it does. Here are the results I get for those two examples:

Original url: http://www.subdomain.site.com
subdomain.site.com
Original url: http://www.www.site.com
www.site.com
Original url: www.subdomain.site.com
subdomain.site.com
Original url: www.www.site.com
www.site.com

 

Ken

 

yes but I said only name plus extension not the www or subdomain prefix

[phpQuestioner]

is this all you want; "subdomain.website.com" from the original "http://www.subdomain.website.com"?

 

if it is - just do this:

 

<?php

$var="http://www.subdomain.website.com";

$myvar = trim($var, "http://www.");

echo "$myvar";

?>

[kenrbnsn]

When you have something like http://www.www.example.com/ only the first "www." is the prefix, the rest is the domain (or subdomain). Since now you're saying you only want the true domain part replace this line in my code

<?php
if (count($tmp2) > 2) $dmp = array_shift($tmp2);
?>

with

<?php
while (count($tmp2) > 2) $dmy = array_shift($tmp2);
?>

now seems it's 100% perfect.

works on all example urls.

thanks ken for you help

[prakash]

in addition I also want to add ip address on $var

so how can it be added

 

when I pass $var="http://111.11.11.11/";

or $var="111.11.11.11"; it's not supported and outputs only 11.11

 

any help?

Here is my code, reworked to satisfy this new condition:

$vars[]='http://site.com/';
$vars[]='site.com';
$vars[]='http://www.subdomain.site.com';
$vars[]='http://www.www.site.com';
$vars[]='www.subdomain.site.com';
$vars[]='www.www.site.com';
$vars[]="http://111.11.11.11/";
$vars[]="111.11.11.11/";
$vars[]='this.is.12.test.com';
foreach($vars as $url) {
   echo 'Original url: ' . $url . "\n";
   if (strtolower(substr($url,0,7)) != 'http://') $url = 'http://' . $url;
   $tmp = parse_url($url);
   $tmp2 = explode('.',$tmp['host']);
   if (count($tmp2) != 4 || !is_ip_addr($tmp2))
      while (count($tmp2) > 2) $dmy = array_shift($tmp2);
   echo implode('.',$tmp2)."\n";
}

function is_ip_addr($ary) {
  $ok = true;
  foreach($ary as $part)
        $ok = is_numeric($part);
