    get_browser() attempts to determine the capabilities of the user's browser. This is done by looking up the browser's information in the browscap.ini file.

    echo $_SERVER['HTTP_USER_AGENT'] . "<hr />\n";

    $browser = get_browser    ();

    foreach (    $browser as $name => $value    ) {
        echo     "<b>$name</b> $value <br />\n"    ;
    }

    Difference between require() and require_once():  require() includes and evaluates a specific file, while require_once() does that only if it has not been included before (on the same page).
    So, require_once() is recommended to use when you want to include a file where you have a lot of functions for example. This way you make sure you don't include the file more times and you will not get the "function re-declared" error.

    Difference between require() and include() is that require() produces a FATAL ERROR if the file you want to include is not found, while include() only produces a WARNING.

    There is also include_once() which is the same as include(), but the difference between them is the same as the difference between require() and require_once().

    Require_once():-using this function we can access the data of another page once i. e we can not access the same page multiple times.

    require():-using this function we can access the data of another page at the desire page multiple times i.e we can access the contents of same page multiple times.

    Include() and require() dose same work.The difference is on error cheeking .Require () gives a fatal error when file cant load whereas include() gives a warning and continue to execute.

    How to use email validation in Java script.Like User can't enter invalid email address?

    First of all, here is the javascript function that tests if an email address is valid.
    It checks for a lot of things: to see if the email contains a "@" sign and a dot, checks to see if the @ is before the dot, and so on.

    <script>
    function isMail(str)
    {
       var at="@";
       var dot=".";
       var lat=str.indexOf(at);
       var lstr=str.length;
       var ldot=str.indexOf(dot);
       if (str.indexOf(at)==-1) return false;
       if (str.indexOf(at)==-1 || str.indexOf(at)==0 || str.indexOf(at)==lstr) return false;
       if (str.indexOf(dot)==-1 || str.indexOf(dot)==0 || str.indexOf(dot)==lstr) return false;
       if (str.indexOf(at,(lat+1))!=-1) return false; if (str.substring(lat-1,lat)==dot || str.substring(lat+1,lat+2)==dot) return false;
       if (str.indexOf(dot,(lat+2))==-1) return false;
       if (str.indexOf(" ")!=-1) return false;
       return true;
    }

    // the next function will be used to validate the form. I made this as a separate function because you might want to validate more fields.
    function validate_form()
    {
       if (!isMail(document.form1.mail.value))
       {
          alert("Please enter a valid email address");
          document.form1.mail.focus();
          return false;
       }
       // if the value entered is not a valid email address, 
       // we show a message, focus on the field and return false.
       // returning false will make sure the form is not submitted

       // if we got here, it means the email address is valid
       return true;
       // return true means that the form is submitted.
    }
    </script>

    After placing this function in the code, here is what you need to put in the form.

    Let's say the form only has the email address and a submit button.

    <form action="/" method="post" onsubmit="return validate_form()" name="form1">
    <input type="text" name="email" value="">
    <input type="submit" name="submit_button" value="continue">
    </form>
