Automatic Intelligent Random Password Generator

mohamed

It is something usual to produce a random password. It is used when a user has forgotten his password and need a new password; or in sum login register forms which the user can not choose his password at first. This script is an intelligent password generator. You set the number of letters and numbers used in the password phrase, and it randomly generates it. If you have a special name, number or character that must be in the phrase, you can insert it in the form. The script randomly select the place of numbers, letters and special phrases.

PHP CODE :

<?php

if (isset($_POST['Gen'])){

$num=$_POST['num'];

$let=$_POST['let'];

$schar=$_POST['schar'];

$sname=$_POST['sname'];

$snum=$_POST['snum'];

$l=strlen($sname)+strlen($snum)+strlen($schar)+$let+$num;

$max=pow(10,$num)-1;

$cnum=rand(1,$max);

if (strlen($cnum)<$num) $cnum=$cnum*pow(10,$num-strlen($cnum));

$clet='';

for ($i=1;$i<=$let;$i++){

$r=rand(1,2);

if ($r==1)

$c=chr(rand(65,90));

else

$c=chr(rand(97,122));

$clet.=$c;

}

$pass_a=array(0,$schar,$sname,$snum,$clet,$cnum);

$pass_b[0]=0;

for ($i=1;$i<=5;$i++){

$used=true;

while ($used==true){

$n=rand(1,5);

$used=false;

for ($j=1;$j<=count($pass_b)-1;$j++)

if ($n==$pass_b[$j]) $used=true;

}

$pass_b[]=$n;

}

?>

You may have visitors that hurt your site and you want to block their access. Here is a code that get this ability to you. just replace the $blocked with the IP that must be blocked.

<?php

$blocked="127.0.0.1";

if (ereg($blocked,$ip)) die('
?>
<p style="text-align: center; color: #FF0000; font-size: 32pt;">
<strong>Your IP is Blocked!</strong>
</p>
<?php
');

Get The Current Page URL

mohamed

Sometimes, you might want to get the current page URL that is shown in the browser URL window. For example if you want to let your visitors submit a blog post to Digg you need to get that same exact URL. There are plenty of other reasons as well. Here is how you can do that.

Add the following code to a page:

<?php
function curPageURL() {
$pageURL = 'http';
if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";}
$pageURL .= "://";
if ($_SERVER["SERVER_PORT"] != "80") {
$pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
} else {
$pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
}
return $pageURL;
}
?>

You can now get the current page URL using the line:

<?php
echo curPageURL();
?>

Sometimes it is needed to get the page name only. The following example shows how to do it:

<?php
function curPageName() {
return substr($_SERVER["SCRIPT_NAME"],strrpos($_SERVER["SCRIPT_NAME"],"/")+1);
}

echo "The current page name is ".curPageName();
?>
