The is_writeable() function checks whether a file is writeable. It returns TRUE if the file exists and is writeable.
The is_writeablle() function is an alias of is_writable(). A benefit of using is_writeable() instead of is_writable() is that the is_writable() function will pollute search results when searching source code for files containing the word "table".
