how to remove this string using regex

[bluewalrus]

Untested in PHP.

$url = preg_replace('/' . $domain . '.*?\/(.*)\/', $domain . '/$1/', $current_page);

i have tried it,
function.preg-replace ]: Unknown modifier '/'
:'(

Try this:

$url = str_replace("index.php", "", $url);  
$url = str_replace("//", "/", $url);

Opps, forgot to close the last one

$url = preg_replace('/' . $domain . '.*?\/(.*)\//', $domain . '/$1/', $current_page); 

That should do it.

I am terrible with functions, but try this:

<?php
$url="http://mysite.com";
$url=preg_replace('/\/index\.php\/?$/',"/",$url);
$url=preg_replace('/\/index\.php\/?/',"/",$url);
$url=preg_replace('/([a-zA-Z])$\/?/',"$1/",$url);
echo "$url";
?>

Jshor, what you propose would also turn http://mysite.com/ into http:/mysite.com/. It still might be possible to do this with str_replace, but I'm not sure how yet.

@james, bluwalrus, jshor: Thanks for all reply from you guys,
i have found my self
my be a little poor,

<?
function menu_top(){
    $domain = "http://www.mysite.ext"; //can be mysite.com, mysite.us, mysite.co.id, mysite.web.id, and so on
    $menu = array(
        'Home' => $domain,
        'People' => $domain.'/people/',
        'News' => $domain.'/news/',
        'Blog' => $domain.'/blog/'
    );

        $current_php_self = str_replace('index.php/', '', $_SERVER['PHP_SELF']);
        $current_php_self = str_replace('index.php', '', $current_php_self);

        $current_page = $domain.$current_php_self;

    
    //this current page always return something like http://www.mysite.ext/index.php/mypage/
    //sometimes return http://www.mysite.ext/index.php
    //
    //home link, in menu shows http://www.mysite.ext/ , but in current_page return http://www.mysite.ext/index.php
    //people link, in menu show http://www.mysite.ext/people/, but in current_page return http://www.mysite.ext/incex.php/people/
    //and the other link are too
    //
    /*
     so, i want a regex to remove index.php from $current_page,
     like:
     http://mysite.com/
     http://mysite.com/people/
    
     not like:
     http://mysite.com/
     http://mysite.com//people/ 
     
     not like:
     http://mysite.com
     http://mysite.com/people/
    */
    $ret ='<ul>';
    foreach($menu as $link_text => $link_url){
        
        if( $current_page == $link_url)
            $ret .='<li class="link_active">'.$link_text.'</li>';
        else
            $ret .='<li><a href="'.$link_url.'">'.$link_text.'</a></li>';
    }
    $ret .='</ul>';
   
    return $ret;
}
?>
