Create Auto Generated Table according to no of record in table

If we want to create table automatic according to no of record come from database;

first we declare how much no of col in table want to display.

<?php

$colNo;

$i=0;

$slectQuery="select title from table";

$Result=mysql_query($selectQuery,$dbc)or die('error in fetch record:-'.mysql_error());

while($row=mysql_fetch_row($Result)){

if($i==0){

echo '<tr>';

}

echo '<td>

$i++;

if($i==$colNo){

echo '</tr>';

$i=0;

}

How to Use a CAPTCHA in php

To put it simply a captcha works by generating a random string, writing it to an image, then storing the string inside of a session or cookie or by some other method. This is then checked when the form or operation is performed.
Their are 7 basic Step

Random text generated
Text written to image
Text stored in session/cookie/database
Image displayed to user
User enters the code
User entered code is checked against the stored key
If they match then something is done

Random text

I will use the php functions, microtime() and mktime() to generate a number. This number will then be encrypted using md5(). With this 32 character long encrypted string we will then use substr() to cut it down to a 5 letter long string. This is our random text.

//Start the session so we can store what the code actually is.
session_start();

//Now lets use md5 to generate a totally random string
$md5 = md5(microtime() * mktime());

/*
We dont need a 32 character long string so we trim it down to 5
*/
$string = substr($md5,0,5);
?>

Text to the image

/*
Now for the GD stuff, for ease of use lets create
the image from a background image.
*/

$captcha = imagecreatefrompng("./captcha.png");

/*
Lets set the colours, the colour $line is used to generate lines.
Using a blue misty colours. The colour codes are in RGB
*/

$black = imagecolorallocate($captcha, 0, 0, 0);
$line = imagecolorallocate($captcha,233,239,239);

/*
Now to make it a little bit harder for any bots to break,
assuming they can break it so far. Lets add some lines
in (static lines) to attempt to make the bots life a little harder
*/
imageline($captcha,0,0,39,29,$line);
imageline($captcha,40,0,64,29,$line);
?>

Text stored in session/cookie

/*
Now for the all important writing of the randomly generated string to the image.
*/
imagestring($captcha, 5, 20, 10, $string, $black);

/*
Encrypt and store the key inside of a session
*/

$_SESSION['key'] = md5($string);

/*
Output the image
*/
header("Content-type: image/png");
imagepng($captcha);
?>
Image displayed to user/User Enter COde
User simple img tag and input box

Check Enter Code is correct or not

session_start();

//Encrypt the posted code field and then compare with the stored key

if(md5($_POST['code']) != $_SESSION['key'])
{
die("Error: You must enter the code correctly");
}else{
echo 'You entered the code correctly';
}
?>
