This code:
<?
//PHP SCRIPT: getimages.php
Header("content-type: application/x-javascript");
//This function gets the file names of all images in the current
directory
//and ouputs them as a JavaScript array
function returnimages($d irname="images" ) {
$pattern="(\.jp g$)|(\.png$)|(\ .jpeg$)|(\.gif$ )"; //valid image
extensions
$files = array();
$curimage=0;
if($handle = opendir($dirnam e)) {
while(false !== ($file = readdir($handle ))){
if(eregi($patte rn, $file)){ //if this file is a valid image
//Output it as a JavaScript array element
echo 'fadeimages['.$curimage.']=["images/'.$file .'", "", ""]';
echo "\n";
$curimage++;
}
}
closedir($handl e);
}
return($files);
}
echo 'var fadeimages=new Array();'; //Define array in JavaScript
echo "\n";
returnimages() //Output the array elements containing the image file
names
?>
captures every file in the images directory into the fadeimages array.
How can I tell php to randomly capture only 5 or so of the images and
store only those in the array? Any help would be greatly appreciated! 2 1338 gu********@gmai l.com wrote: This code captures every file in the images directory into the fadeimages array. How can I tell php to randomly capture only 5 or so of the images and store only those in the array?
Instead of outputting every file name, store file names in an array
(lets say, $files) and then randomly draw five elements from that
array:
$n = count($files) - 1;
for ($i=1; $i <= 5; $i++) {
echo 'fadeimages[', $i, ']=["images/', $files[rand(0, $n)] ,'", "",
""]';
}
For more information on rand(), see the Manual: http://www.php.net/rand

My understanding -- I'm not an expert -- is that on (some? many? all?)
standard Internet servers a URL can point to a subdirectory name
followed by a backslash, and that links to this URL will automatically
go to an "index.html" file located in that subdirectory, if there is one.
Q1: Is this more or less correct?
At least some HTML texts also recommend using this as the basis for
organizing a web site: Put the web pages associated...

What is the default directory in the client file system that is used for
file urls?
From performing a few experiments, it is clear that an unqualified
reference from another file url is always directed to the source directory.
I.e., from within url "file://c:/abc/def.htm", if you make a reference like
<href="ghi.htm">, or <img src="jkl.gif">,the browser will look for
"file://c:/abc/ghi.htm" or "file://c:/abc/jkl.gif".

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
