Takes a given directory and lists all the files and folders under it, including sub folders. Resulting array contains associative (folders) and indexed (files) elements. Doesn't return "." and ".."

This function takes a directory, and a "folder" search parameter.
If it finds the directory (either in single level, or any sub folder) it will return the relative path of that folder. "FALSE" if not found. Skips over files and "." and ".." directories. Recursive by default.

This function tries to locate a file in a give folder (either single level, or in any sub folder). Returns the relative file and path, or FALSE if not found. Skips over "." and "..".

This function will take four arguments, the year, month, day and number of days in the future you want to go and return to you as an array (year,month,day) of that date.

It is a simple function that is only for convenience. It is meant to be used in conjunction with the list() command.

This function will let you find the Sunday, Monday, Tuesday, etc of a month and return to you that date.

It is a modification of a script I found online at this site: http://filchiprogrammer.wordpress.com/2008/02/27/getting-the-first-monday-of-the-month/.

The function takes three arguments, the month, year and the weekday you are looking for. The weekday is represented by an integer, 0 for Sunday, 1 for Monday and so on.

Cuando concatenamos varios campos con CONCAT( Campo1, Campo2,... ) si algún valor es NULL no se realiza la concatenación, para concater campos (aunque algunos tengan NULL) usaremos COALESCE que devuelve el primer valor que no sea null de la lista.
Asi le pasaremos una listca con el nombre del campo seguido de "", si el campo estava lleno, devuelve el campo, si es null devuelve el segundo, es decir ""

Best use of ob_, custom error handling, and variable variales evar: simple templating.

_parse($filename[,$locals])
includes $filename and renders its output to the return value. $locals, if used, will add a set of variables to the included context.

Parse($template[,$locals])
Same as above, but allows you to define a base template folder and omit the .php - just for cleaner code.

t($template[,$obj])
...
t()
Same as Parse, but any output between the opening call and the closing call (no arguments) will be buffered intot he $content variable of the template.

Play around with t(..) to find out more; I don't feel like documenting it.

This little function does great for passwords, usernames, files, and anything else you need a random string for.
