Re: How to change pictures everyday using php

you could modify the input file.

name1.jpg,some text here
name2.jpg,todays text here
name3.jpg,different text here


in the script:
change this line

if(count($lines)<$dayofyear) $todayspicture = $lines[$dayofyear];

to

if(count($lines)<$dayofyear) {
$todaysdata = $lines[$dayofyear]; // get line from array
$todaysdataarray = explode(",",$todaysdata); // create array of todays data
$todayspicture = $todaysdataarray[0]; // assign first element of array to
todays picture
$alt = $todaysdataarray[1]; // assign second element of array to alt
}
