Descriptionstring dbplus_chdir ( [string newdir])
This function is EXPERIMENTAL. The behaviour of this function, the name of this function, and anything else documented about this function may change without notice in a future release of PHP. Use this function at your own risk.
dbplus_chdir() will change the virtual current directory where relation files will be looked for by dbplus_open(). dbplus_chdir() will return the absolute path of the current directory. Calling dbplus_chdir() without giving any newdir may be used to query the current working directory.
