Home / Randomizers	Today :

Random ID Strings Works best as an include file. The functions will return a string of random characters of any specified length. You choose upper&lowercase letters and numbers, numbers only, upper&lowercase letters only, or lowercase letters only. Also includes a function to create anti-robot images if you have a directory with images in it. (named a.gif, b.gif, etc.) You need upper and lowercase images and number images. Very handy for user sign-ups!

Random Text State Have you ever wanted to have your text randomly inserted in uppercase or lowercase for any specific reason? Well now you can do it with my handy function that uses moduls division to output the same result everytime! The usage of this function is quite simple just go:

Random Picture Display This code will display a picture at random from the specified directory.

The $file_dir variable is the relative path to the pictures folder.

The $f_type variable is the extension of the image files that you wish to display. In the example, all the files that I wish to display end in "tm.jpg"

Finally, you must ensure that the second argument in the explode function matches the number of characters specified in the extension variable. In my example the digit is 6 because my extension (tm.jpg) has 6 characters.
