This is the code that i have on my site for url link's. I want to make a new think:
-each time when a user post a url: http://youtube.com/watch?blablabla , i want to show on the site : Link youtube
-each time when a user post a url" http://www.facebook.com/picture/etcetcetctjkjk , i want to show on the site: Link facebook
Anyone have an ideea how to make something like this? I gues that with preg_replace or url_parsing but i don't know how

[something else]

$str = preg_replace('/http:\/\/(.*)./is', $1, $arr[2]);
// $str is now the site name instead of $arr[2]


//or

$str = explode(".",explode("://",$arr[2]));
// $str[1] is now the site name instead of $arr[2]

//or there is many other ways to script it :P

$str = preg_replace('/http:\/\/(.*)./is', $1, $arr[2]);
// $str is now the site name instead of $arr[2]


//or

$str = explode(".",explode("://",$arr[2]));
// $str[1] is now the site name instead of $arr[2]

//or there is many other ways to script it :P 

where i put this?

function links_preg2($arr)
{
    global $set;
    if (preg_match('#^http://' . preg_quote($_SERVER['HTTP_HOST']) . '#',$arr[2]))
    return $arr[1] . '<a href="' . $arr[2] . '">' . $arr[2] . '</a>' . $arr[4];
    else
    return $arr[1] . '<a' . ($set['web'] ? ' target="_blank"' : null) . ' href="http://' . $_SERVER['HTTP_HOST'] . '/go.php?go=' . base64_encode(html_entity_decode($arr[2])) . '">Link</a>' . $arr[4];
} 

i can't do it, Warning: explode() expects parameter 2 to be string, array given in

oops i missed an array key out in the 2nd code >.<

try this:

function links_preg2($arr)
{
    global $set;
        $str = preg_replace('/http:\/\/(.*)./is', $1, $arr[2]); 
    if (preg_match('#^http://' . preg_quote($_SERVER['HTTP_HOST']) . '#',$arr[2]))
    return $arr[1] . '<a href="' . $arr[2] . '">' . $str . '</a>' . $arr[4];
    else
    return $arr[1] . '<a' . ($set['web'] ? ' target="_blank"' : null) . ' href="http://' . $_SERVER['HTTP_HOST'] . '/go.php?go=' . base64_encode(html_entity_decode($arr[2])) . '">Link</a>' . $arr[4];
}

} 

Parse error: syntax error, unexpected T_LNUMBER, expecting T_VARIABLE or '$' in on line

$str = preg_replace('/http:\/\/(.*)./is', $1, $arr[2]); 

Added after 3 minutes:

fixed: i put $arr[1] instead $1 .

Now i put

 '#^(https://|http://)?(www|m)?\.?(youtube\.com|youtu.be)(/watch(\.php)?\?v=|/v/|/)(?P<id>[a-zA-Z0-9-_]{11})(?P<rest>[\w&=/\?\.\#\+]+)?#ism'. '#' 

in $str?

Added after 17 minutes:

i put this code:

function links_preg2($arr) 
{ 
    global $set; 
        $str = preg_replace('#(https://|http://)?(www|m)?\.?(youtube\.com|youtu.be)(/watch(\.php)?\?v=|/v/|/)(?P<id>[a-zA-Z0-9-_]{11})(?P<rest>[\w&=/\?\.\#\+]+)?#ism', $arr[1], $arr[2]);
        
    if (preg_match('#^http://' . preg_quote($_SERVER['HTTP_HOST']) . '#',$arr[2])) 
    return $arr[1] . '<a href="' . $arr[2] . '">' . $str . '</a>' . $arr[4]; 
    else 
    return $arr[1] . '<a' . ($set['web'] ? ' target="_blank"' : null) . ' href="http://' . $_SERVER['HTTP_HOST'] . '/go.php?go=' . base64_encode(html_entity_decode($arr[2])) . '">Link</a>' . $arr[4]; 
} 
function links($msg)
{
    global $set;
    if ($set['bb_img'])$msg = preg_replace_callback('/\[img\](.+)\[\/img\]/isU', 'img_preg', $msg);
    if ($set['bb_url'])$msg = preg_replace_callback('/\[url=(.+)\](.+)\[\/url\]/isU', 'links_preg1', $msg);
    
    if ($set['bb_http'])$msg = preg_replace_callback('~(^|\s)([a-z]+://([^ \r\n\t`\'"]+))(\s|$)~iu', 'links_preg2', $msg); 

but don't work: when i put this link on status http://www.youtube.com/watch?v=YAJ9ArSlUG0 doesn't appear Link Youtube, only Link

[something else]

ok i tried it myself and i forgot the quotes around the "$1"

So i tested this:

<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);
$arr[2] = "http://google.com";
$str = preg_replace('/http:\/\/(.*)./is', "$1", $arr[2]); 
echo $str;
?>

However this gave an unexpected result: google.co to which i am slighhtly confused to why it is doing that >.< arnage is good at preg_replace so he might be able to tell whats wrong with it.


anyway here is a working version:

function links_preg2($arr) 
{ 
    global $set; 
     $str = explode("://",$arr[2]);
    $str = explode(".",$str[1]); 
    if (preg_match('#^http://' . preg_quote($_SERVER['HTTP_HOST']) . '#',$arr[2])) 
    return $arr[1] . '<a href="' . $arr[2] . '">' . $str[0] . '</a>' . $arr[4]; 
    else 
    return $arr[1] . '<a' . ($set['web'] ? ' target="_blank"' : null) . ' href="http://' . $_SERVER['HTTP_HOST'] . '/go.php?go=' . base64_encode(html_entity_decode($arr[2])) . '">Link</a>' . $arr[4]; 
} 

[tzapone]

function links_preg2($arr)  
{  
    global $set;  
     $str = explode("://",$arr[2]); 
    $str = explode("/",$str[1]);  
    if (preg_match('#^http://' . preg_quote($_SERVER['HTTP_HOST']) . '#',$arr[2]))  
    return $arr[1] . '<a href="' . $arr[2] . '">' . $str[0] . '</a>' . $arr[4];  
    else  
    return $arr[1] . '<a' . ($set['web'] ? ' target="_blank"' : null) . ' href="http://' . $_SERVER['HTTP_HOST'] . '/go.php?go=' . base64_encode(html_entity_decode($arr[2])) . '">Link '.$str[0].'</a>' . $arr[4];  
} 

I did it with this function :D

Thank's for the help.

Your welcome

btw error was with (.*) regex in the preg_replace it needed [^a-zA-Z0-9] regex
the end "." must be to go back 1 letter which produce the .co instead of .com

Anyway, using explode or preg_replace fails due to sub-domains eg: http://m.youtube.com which will produces the letter "m"

but that's as far as I'm willing to script atm :P
