I want to write a php program to grab a report that changes each day so I could save a copy in a DH directory for a permanent record. The url is :http://www.usbr.gov/pn/hydromet/yakima/yakstats.txt. I started writing a little php program to give the url to curl, then explode it on newline characters to an array, then write the array to a file and save to a directory with the file name derived from the current system date. But then I thought, hey it’s already just a text file. Do I need to get this complicated? Is there a way to just copy the text file from the original location to my directory? A shell script even?
