The following functions are available:

+ +

random_string()

+ +

Generates a random string based on the type and length you specify. Useful for creating passwords or generating random hashes.

+ +

The first parameter specifies the type of string, the second parameter specifies the length. The following choices are available:

+ + +

alnum: Alpha-numeric string with lower and uppercase characters.
numeric: Numeric string.
nozero: Numeric string with no zeros.
unique: Encrypted with MD5 and uniquid(). Note: The length parameter is not available for this type. +Returns a fixed length 33 character string.

+ +

Usage example:

+ +echo random_string('alnum', 16); + + +

alternator()

+ +

Allows two or more items to be alternated between, when cycling through a loop. Example: + +for ($i = 0; $i < 10; $i++) +{ + echo alternator('string one', 'string two'); +} + + +

You can add as many parameters as you want, and with each each iteration of your loop the next item will be returned.

+ +

for ($i = 0; $i < 10; $i++)

+{

+    echo alternator('one', 'two', 'three', 'four', 'five');

+}

+

+ +

Note: To use multiple separate calls to this function simply call the function with no arguments to re-initialize.

+ + + +

repeater()

Generates repeating copies of the data you submit. Example:

$string = "\n";

+echo repeater($string, 30);

+ +

The above would generate 30 newlines.
