PHP Random Text

**GamingHybrid** · July 1st, 2007, 2:04 AM

Well, I've been checking via Google and such, but there is no help... either has information on random numbers or inefficient ways to make random things...

Anyone have a simple, easy customize, php code for randomly displaying text (changes on reload)? I might just go java...

what kind of text are you looking to display? If you have like a few phrases, I would say just use a switch and a random number to pick one to display or use.

Here's what I use to spit out a 5 character image from randomly generated text. You could probably put the chr(rand(48,126)) part inside a loop to generate however many characters you needed and dump all the image stuff and just echo out $code if all you wanted was the text.

PHP Code:


			
<?php

    session_start();

    // generate random characters and output it as an image



    $code = chr(rand(48,126)).chr(rand(48,126)).chr(rand(48,126)).chr(rand(48,126)).chr(rand(48,126));

    $im = @imagecreate(60, 20) or die("Cannot Initialize new GD image stream");

    $background_color = imagecolorallocate($im, 255, 255, 255);

    $text_color = imagecolorallocate($im, 233, 14, 91);

    imagestring($im, 4, 3, 3,  $code, $text_color);

    //imagepng($im);

    $_SESSION['code'] = $code;

    header("Content-type: image/gif");

    imagegif($im);

    imagedestroy($im);

?>

wait, are these set phrases that you want to display randomly? or you just want a random word showing up much like a bot-deterant thing

Hey MarkRH, could anyone use that, if so, I may if I can get my contact form up, implement that for verification, way better then what I had.

Thanks.

Sure.. just include it (a separate php file) as the src of an img tag. Add a field in the form to accept input from the user.. and then check the value in the form field against the session variable. Most bots don't even request the php file and the session variable doesn't even exist.

It's in action on my guestbook. I reset my guestbook log at 10:23 this morning and 55 failed attempts so far.

thank you MarkRH, plus explaining its use, this will make the form even better.

Thanks for the help, sorry I never replied!

I foudn a solution from using a .txt that had a word on each line. Basically, it would display a random image, but this image was made of three different ones... so a random word would define the name of the image for all three.

Thanks for the help though!
