Array of problems with arrays
Posted: Thu Nov 17, 2011 5:17 pm
Hi,
I cannot, for the life of me, figure out what is happening. I have the following:
About ten lines up (directories = getFileList...) I am trying to get a list of the folders in that folder. when I print_r($directories), I get the following output:
Array ( [0] => Array ( [name] => apps/plogger-1.0RC1/plog-content/images/varsity-football---2011/guestbook/ ) [1] => Array ( [name] => apps/plogger-1.0RC1/plog-content/images/varsity-football---2011/2011-gateway-game/ ) [2] => Array ( [name] => apps/plogger-1.0RC1/plog-content/images/varsity-football---2011/varsity-football---2011-kickoff-classic-vs.-ocoee/ ) [3] => Array ( [name] => apps/plogger-1.0RC1/plog-content/images/varsity-football---2011/2011-lake-mary-game/ ) [4] => Array ( [name] => apps/plogger-1.0RC1/plog-content/images/varsity-football---2011/uhs-spring-2011-game-vs.-poincianna/ ) [5] => Array ( [name] => apps/plogger-1.0RC1/plog-content/images/varsity-football---2011/index.php ) [6] => Array ( [name] => apps/plogger-1.0RC1/plog-content/images/varsity-football---2011/2011-hagerty-game/ ) [7] => Array ( [name] => apps/plogger-1.0RC1/plog-content/images/varsity-football---2011/2011-deltona-game/ ) )
I want to pull one random path from this array. When I
resultant output is the word Array about ten times. I have tried echo array_slice($directories,1,1), and echo $directories[0], echo $directories[1] and so forth, each time the word Array, not the contents of the 1st or 2nd element.
I am simply trying to select photos from a random folder on each page load. grrr. I hate my job, anyone hiring beer taste testers???
Thanks in advance,
