Ever wondered how many people know what a browser is? If you haven’t this video may make you cry a little.
I was recently on YouTube and I noticed that did not check the shortened strings for potentially embarrassing shortenings of words.
How to make a great example?
Here is the code so you can shorten strings and check for potentially embrassing words.
A few months ago 3 Google employees explored an innovative approach to CAPTCHA (What’s Up CAPTCHA? A CAPTCHA Based On Image Orientation). Essentially they suggested that having a user orientate an image into its upright position is easier for users (typing difficult to read text can be problematic) and harder for computers.
A computer finds it really difficult to know if this is correctly orientated.
Here is a version I wrote which to can use on your website.
This script makes use of jQuery to allow the user to rotate the images and a little PHP to check the image was rotated into the correct position.
Handling errors in PHP can be quite a handful at times. Here is a really simple PHP class which I use to manage errors:
<?php
/*
errors class - Helps management of errors in a script.

$this->errors_data[] = $new_error;
return TRUE;
}

public function output_errors(){
if(is_array($this->errors_data)){
// Cycle through the errors.
foreach($this->errors_data as $error) {
$return .= '<p>'.$error.'</p>';
}
// Add it to the error div
return '<div id="error">'.$return.'</div>';
}
return NULL;
}
}
// @Example - creating the class:
$errors = new errors;
// @Example - Add an error
$errors->add_error('Username is incorrect');
// @Example - Return the errors
echo $errors->output_errors();
?>
If you are looking to fully integrate a script similar to the above, there is a really good post regarding the set_error_handler() function on Tinsology ( PHP Error Handling ).
